THE MILK LETTER : A MESSAGE TO MY PATIENTS

"MILK"Just the word itself sounds
comforting! "How about a nice cup of hot milk?" The last time you
heard that question it was from someone who cared for you--and you
appreciated their effort.
The entire matter of food and especially that
of milk is surrounded with emotional and cultural importance. Milk was our
very first food. If we were fortunate it was our mother's milk. A loving
link, given and taken. It was the only path to survival. If not mother's milk
it was cow's milk or soy milk "formula"--rarely it was goat, camel
or water buffalo milk.
Now, we are a nation of milk drinkers. Nearly
all of us. Infants, the young, adolescents, adults and even the aged. We
drink dozens or even several hundred gallons a year and add to that many
pounds of "dairy products" such as cheese, butter, and yogurt.
Can there be anything wrong with this? We see
reassuring images of healthy, beautiful people on our television screens and
hear messages that assure us that, "Milk is good for your body."
Our dieticians insist that: "You've got to have milk, or where will you
get your calcium?" School lunches always include milk and nearly every
hospital meal will have milk added. And if that isn't enough, our nutritionists
told us for years that dairy products make up an "essential food
group." Industry spokesmen made sure that colourful charts proclaiming
the necessity of milk and other essential nutrients were made available at no
cost for schools. Cow's milk became "normal."
You may be surprised to learn that most of
the human beings that live on planet Earth today do not drink or use cow's
milk. Further, most of them can't drink milk because it makes them ill.
There are students of human nutrition who are
not supportive of milk use for adults. Here is a quotation from the
March/April 1991 Utne Reader:
If you really want to play it safe, you may
decide to join the growing number of Americans who are eliminating dairy
products from their diets altogether. Although this sounds radical to those
of us weaned on milk and the five basic food groups, it is eminently viable.
Indeed, of all the mammals, only humans--and then only a minority,
principally Caucasians--continue to drink milk beyond babyhood. Indeed, of
all the mammals, only humans--and then only a minority, principally
Caucasians--continue to drink milk beyond babyhood.
Who is right? Why the confusion? Where best
to get our answers? Can we trust milk industry spokesmen? Can you trust any
industry spokesmen? Are nutritionists up to date or are they simply repeating
what their professors learned years ago? What about the new voices urging
caution?
I believe that there are three reliable
sources of information. The first, and probably the best, is a study of
nature. The second is to study the history of our own species. Finally we
need to look at the worlds scientific literature on the subject of milk.
Lets look at the scientific literature
first. From 1988 to 1993 there were over 2,700 articles dealing with milk
recorded in the Medicine archives. Fifteen hundred of theses had milk as
the main focus of the article. There is no lack of scientific information on
this subject. I reviewed over 500 of the 1,500 articles, discarding articles
that dealt exclusively with animals, esoteric research and inconclusive
studies.
How would I summarize the articles? They were
only slightly less than horrifying. First of all, none of the authors spoke
of cows milk as an excellent food, free of side effects and the perfect
food as we have been led to believe by the industry. The main focus of the
published reports seems to be on intestinal colic, intestinal irritation,
intestinal bleeding, anemia, allergic reactions in infants and children as
well as infections such as salmonella. More ominous is the fear of viral
infection with bovine leukemia virus or an AIDS-like virus as well as concern
for childhood diabetes. Contamination of milk by blood and white (pus) cells
as well as a variety of chemicals and insecticides was also discussed. Among
children the problems were allergy, ear and tonsillar infections, bedwetting,
asthma, intestinal bleeding, colic and childhood diabetes. In adults the
problems seemed centered more around heart disease and arthritis, allergy,
sinusitis, and the more serious questions of leukemia, lymphoma and cancer.
I think that an answer can also be found in a
consideration of what occurs in nature what happens with free living
mammals and what happens with human groups living in close to a natural state
as hunter-gatherers.
Our paleolithic ancestors are another crucial
and interesting group to study. Here we are limited to speculation and
indirect evidences, but the bony remains available for our study are
remarkable. There is no doubt whatever that these skeletal remains reflect
great strength, muscularity (the size of the muscular insertions show this),
and total absence of advanced osteoporosis. And if you feel that these people
are not important for us to study, consider that today our genes are
programming our bodies in almost exactly the same way as our ancestors of
50,000 to 100,000 years ago.
WHAT IS MILK?
Milk is a maternal lactating secretion, a
short term nutrient for new-borns. Nothing more, nothing less. Invariably,
the mother of any mammal will provide her milk for a short period of time
immediately after birth. When the time comes for weaning, the young
offspring is introduced to the proper food for that species of mammal. A
familiar example is that of a puppy. The mother nurses the pup for just a few
weeks and then rejects the young animal and teaches it to eat solid food.
Nursing is provided by nature only for the very youngest of mammals. Of
course, it is not possible for animals living in a natural state to continue
with the drinking of milk after weaning.
IS ALL MILK THE SAME?
Then there is the matter of where we get our
milk. We have settled on the cow because of its docile nature, its size, and
its abundant milk supply. Somehow this choice seems normal and blessed by
nature, our culture, and our customs. But is it natural? Is it wise to drink
the milk of another species of mammal?
Consider for a moment, if it was possible, to
drink the milk of a mammal other than a cow, lets say a rat. Or perhaps the
milk of a dog would be more to your liking. Possibly some horse milk or cat
milk. Do you get the idea? Well, Im not serious about this, except to
suggest that human milk is for human infants, dogs milk is for pups, cows
milk is for calves, cats milk is for kittens, and so forth. Clearly, this is
the way nature intends it. Just use your own good judgement on this one.
Milk is not just milk. The milk of every
species of mammal is unique and specifically tailored to the requirements of
that animal. For example, cows' milk is very much richer in protein than
human milk. Three to four times as much. It has five to seven times the
mineral content. However, it is markedly deficient in essential fatty acids
when compared to human mothers' milk. Mothers' milk has six to ten times as
much of the essential fatty acids, especially linoleic acid. (Incidentally,
skimmed cows milk has no linoleic acid). It simply is not designed for
humans.
Food is not just food, and milk is not just
milk. It is not only the proper amount of food but the proper qualitative
composition that is critical for the very best in health and growth.
Biochemists and physiologists - and rarely medical doctors - are gradually
learning that foods contain the crucial elements that allow a particular
species to develop its unique specializations.
Clearly, our specialization is for advanced
neurological development and delicate neuromuscular control. We do not have
much need of massive skeletal growth or huge muscle groups as does a calf.
Think of the difference between the demands make on the human hand and the
demands on a cow's hoof. Human new-borns specifically need critical material
for their brains, spinal cord and nerves.
Can mothers milk increase intelligence? It
seems that it can. In a remarkable study published in Lancet during 1992
(Vol. 339, p. 261-4), a group of British workers randomly placed premature
infants into two groups. One group received a proper formula, the other group
received human breast milk. Both fluids were given by stomach tube. These
children were followed up for over 10 years. In intelligence testing, the
human milk children averaged 10 IQ points higher! Well, why not? Why wouldnt
the correct building blocks for the rapidly maturing and growing brain have a
positive effect?
In the American Journal of Clinical Nutrition
(1982) Ralph Holman described an infant who developed profound neurological
disease while being nourished by intravenous fluids only. The fluids used
contained only linoleic acid - just one of the essential fatty acids. When
the other, alpha linoleic acid, was added to the intravenous fluids the
neurological disorders cleared.
In the same journal five years later Bjerve,
Mostad and Thoresen, working in Norway found exactly the same problem in
adult patients on long term gastric tube feeding.
In 1930 Dr. G.O. Burr in Minnesota working
with rats found that linoleic acid deficiencies created a deficiency
syndrome. Why is this mentioned? In the early 1960s pediatricians found skin
lesions in children fed formulas without the same linoleic acid. Remembering
the research, the addition of the acid to the formula cured the problem.
Essential fatty acids are just that and cows milk is markedly deficient in
these when compared to human milk.
WELL, AT LEAST COW'S MILK IS PURE
Or is it? Fifty years ago an average cow
produced 2,000 pounds of milk per year. Today the top producers give 50,000
pounds! How was this accomplished? Drugs, antibiotics, hormones, forced
feeding plans and specialized breeding; that's how.
The latest high-tech onslaught on the poor
cow is bovine growth hormone or BGH. This genetically engineered drug is
supposed to stimulate milk production but, according to Monsanto, the
hormone's manufacturer, does not affect the milk or meat. There are three
other manufacturers: Upjohn, Eli Lilly, and American Cyanamid Company.
Obviously, there have been no long-term studies on the hormone's effect on
the humans drinking the milk. Other countries have banned BGH because of safety
concerns. One of the problems with adding molecules to a milk cows' body is
that the molecules usually come out in the milk. I don't know how you feel,
but I don't want to experiment with the ingestion of a growth hormone. A
related problem is that it causes a marked increase (50 to 70 per cent) in
mastitis. This, then, requires antibiotic therapy, and the residues of the
antibiotics appear in the milk. It seems that the public is uneasy about this
product and in one survey 43 per cent felt that growth hormone treated milk
represented a health risk. A vice president for public policy at Monsanto was
opposed to labelling for that reason, and because the labelling would create
an artificial distinction. The country is awash with milk as it is, we produce
more milk than we can consume. Lets not create storage costs and further
taxpayer burdens, because the law requires the USDA to buy any surplus of
butter, cheese, or non-fat dry milk at a support price set by Congress! In
fiscal 1991, the USDA spent $757 million on surplus butter, and one billion
dollars a year on average for price supports during the 1980s (Consumer
Reports, May 1992: 330-32).
Any lactating mammal excretes toxins through
her milk. This includes antibiotics, pesticides, chemicals and hormones.
Also, all cows' milk contains blood! The inspectors are simply asked to keep
it under certain limits. You may be horrified to learn that the USDA allows
milk to contain from one to one and a half million white blood cells per
millilitre. (Thats only 1/30 of an ounce). If you dont already know this,
Im sorry to tell you that another way to describe white cells where they
dont belong would be to call them pus cells. To get to the point, is milk
pure or is it a chemical, biological, and bacterial cocktail? Finally, will
the Food and Drug Administration (FDA) protect you? The United States General
Accounting Office (GAO) tells us that the FDA and the individual States are
failing to protect the public from drug residues in milk. Authorities test
for only 4 of the 82 drugs in dairy cows.
As you can imagine, the Milk Industry
Foundation's spokesman claims it's perfectly safe. Jerome Kozak says, "I
still think that milk is the safest product we have."
Other, perhaps less biased observers, have
found the following: 38% of milk samples in 10 cities were contaminated with
sulfa drugs or other antibiotics. (This from the Centre for Science in the
Public Interest and The Wall Street Journal, Dec. 29, 1989).. A similar study
in Washington, DC found a 20 percent contamination rate (Nutrition Action
Healthletter, April 1990).
Whats going on here? When the FDA tested
milk, they found few problems. However, they used very lax standards. When
they used the same criteria , the FDA data showed 51 percent of the milk samples
showed drug traces.
Lets focus in on this because its critical
to our understanding of the apparent discrepancies. The FDA uses a disk-assay
method that can detect only 2 of the 30 or so drugs found in milk. Also, the
test detects only at the relatively high level. A more powerful test called
the Charm II test can detect 4o drugs down to 5 parts per billion.
One nasty subject must be discussed. It seems
that cows are forever getting infections around the udder that require
ointments and antibiotics. An article from France tells us that when a cow
receives penicillin, that penicillin appears in the milk for from 4 to 7
milkings. Another study from the University of Nevada, Reno tells of cells in
mastic milk, milk from cows with infected udders. An elaborate analysis of
the cell fragments, employing cell cultures, flow cytometric analysis , and a
great deal of high tech stuff. Do you know what the conclusion was? If the
cow has mastitis, there is pus in the milk. Sorry, its in the study, all
concealed with language such as
macrophages containing many vacuoles and
phagocytosed particles, etc.
IT GETS WORSE
Well, at least human mothers' milk is pure!
Sorry. A huge study showed that human breast milk in over 14,000 women had
contamination by pesticides! Further, it seems that the sources of the
pesticides are meat and--you guessed it--dairy products. Well, why not? These
pesticides are concentrated in fat and that's what's in these products. (Of
interest, a subgroup of lactating vegetarian mothers had only half the levels
of contamination).
A recent report showed an increased
concentration of pesticides in the breast tissue of women with breast cancer
when compared to the tissue of women with fibrocystic disease. Other articles
in the standard medical literature describe problems. Just scan these titles:
1.Cows Milk as a Cause of Infantile Colic
Breast-Fed Infants. Lancet 2 (1978): 437 2.Dietary Protein-Induced Colitis
in Breast- Fed Infants, J. Pediatr. I01 (1982): 906 3.The Question of the
Elimination of Foreign Protein in Womens Milk, J. Immunology 19 (1930): 15
There are many others. There are dozens of
studies describing the prompt appearance of cows milk allergy in children
being exclusively breast-fed! The cows milk allergens simply appear in the
mothers milk and are transmitted to the infant.
A committee on nutrition of the American
Academy of Pediatrics reported on the use of whole cows milk in infancy
(Pediatrics 1983: 72-253). They were unable to provide any cogent reason why
bovine milk should be used before the first birthday yet continued to
recommend its use! Doctor Frank Oski from the Upstate Medical Centre
Department of Pediatrics, commenting on the recommendation , cited the
problems of occult gastrointestinal blood loss in infants, the lack of iron,
recurrent abdominal pain, milk-borne infections and contaminants, and said:
Why give it at all - then or ever? In the
face of uncertainty about many of the potential dangers of whole bovine milk,
it would seem prudent to recommend that whole milk not be started until the
answers are available. Isnt it time for these uncontrolled experiments on
human nutrition to come to an end?
In the same issue of Pediatrics he further
commented:
It is my thesis that whole milk should not be
fed to the infant in the first year of life because of its association with
iron deficiency anemia (milk is so deficient in iron that an infant would
have to drink an impossible 31 quarts a day to get the RDA of 15 mg), occult gastrointiestinal
bleeding, and various manifestations of food allergy. I suggest that
unmodified whole bovine milk should not be consumed after infancy because of
the problems of lactose intolerance, its contribution to the genesis of
atherosclerosis, and its possible link to other diseases.
In late 1992 Dr. Benjamin Spock, possibly the
best known pediatrician in history, shocked the country when he articulated
the same thoughts and specified avoidance for the first two years of life.
Here is his quotation:
I want to pass on the word to parents that
cows milk from the carton has definite faults for some babies. Human milk is
the right one for babies. A study comparing the incidence of allergy and
colic in the breast-fed infants of omnivorous and vegan mothers would be
important. I havent found such a study; it would be both important and
inexpensive. And it will probably never be done. There is simply no academic
or economic profit involved.
OTHER PROBLEMS
Let's just mention the problems of bacterial
contamination. Salmonella, E. coli, and staphylococcal infections can be
traced to milk. In the old days tuberculosis was a major problem and some
folks want to go back to those times by insisting on raw milk on the basis
that it's "natural." This is insanity! A study from UCLA showed
that over a third of all cases of salmonella infection in California,
1980-1983 were traced to raw milk. That'll be a way to revive good old
brucellosis again and I would fear leukemia, too. (More about that later). In
England, and Wales where raw milk is till consumed there have been outbreaks
of milk-borne diseases. The Journal of the American Medical Association (251:
483, 1984) reported a multi-state series of infections caused by Yersinia
enterocolitica in pasteurised whole milk. This is despite safety precautions.
All parents dread juvenile diabetes for their
children. A Canadian study reported in the American Journal of Clinical
Nutrition, Mar. 1990, describes a "...significant positive correlation
between consumption of unfermented milk protein and incidence of insulin
dependent diabetes mellitus in data from various countries. Conversely a
possible negative relationship is observed between breast-feeding at age 3
months and diabetes risk.".
Another study from Finland found that
diabetic children had higher levels of serum antibodies to cows milk
(Diabetes Research 7(3): 137-140 March 1988). Here is a quotation from this
study:
We infer that either the pattern of cows
milk consumption is altered in children who will have insulin dependent
diabetes mellitus or, their immunological reactivity to proteins in cows
milk is enhanced, or the permeability of their intestines to cows milk
protein is higher than normal.
The April 18, 1992 British Medical Journal
has a fascinating study contrasting the difference in incidence of juvenile
insulin dependent diabetes in Pakistani children who have migrated to
England. The incidence is roughly 10 times greater in the English group
compared to children remaining in Pakistan! What caused this highly
significant increase? The authors said that the diet was unchanged in Great
Britain. Do you believe that? Do you think that the availability of milk,
sugar and fat is the same in Pakistan as it is in England? That a grocery
store in England has the same products as food sources in Pakistan? I dont
believe that for a minute. Remember, were not talking here about adult
onset, type II diabetes which all workers agree is strongly linked to diet as
well as to a genetic predisposition. This study is a major blow to the its
all in your genes crowd. Type I diabetes was always considered to be genetic
or possibly viral, but now this? So resistant are we to consider diet as
causation that the authors of the last article concluded that the cooler
climate in England altered viruses and caused the very real increase in
diabetes! The first two authors had the same reluctance top admit the
obvious. The milk just may have had something to do with the disease.
The latest in this remarkable list of
reports, a New England Journal of Medicine article (July 30, 1992), also
reported in the Los Angeles Times. This study comes from the Hospital for
Sick Children in Toronto and from Finnish researchers. In Finland there is
"...the world's highest rate of dairy product consumption and the
world's highest rate of insulin dependent diabetes. The disease strikes about
40 children out of every 1,000 there contrasted with six to eight per 1,000
in the United States.... Antibodies produced against the milk protein during
the first year of life, the researchers speculate, also attack and destroy
the pancreas in a so-called auto-immune reaction, producing diabetes in
people whose genetic makeup leaves them vulnerable." "...142
Finnish children with newly diagnosed diabetes. They found that every one had
at least eight times as many antibodies against the milk protein as did
healthy children, clear evidence that the children had a raging auto immune
disorder." The team has now expanded the study to 400 children and is
starting a trial where 3,000 children will receive no dairy products during
the first nine months of life. "The study may take 10 years, but we'll
get a definitive answer one way or the other," according to one of the
researchers. I would caution them to be certain that the breast feeding
mothers use on cows' milk in their diets or the results will be confounded by
the transmission of the cows' milk protein in the mother's breast milk....
Now what was the reaction from the diabetes association? This is very
interesting! Dr. F. Xavier Pi-Sunyer, the president of the association says:
"It does not mean that children should stop drinking milk or that
parents of diabetics should withdraw dairy products. These are rich sources
of good protein." (Emphasis added) My God, it's the "good
protein" that causes the problem! Do you suspect that the dairy industry
may have helped the American Diabetes Association in the past?
LEUKEMIA? LYMPHOMA? THIS MAY BE THE
WORST--BRACE YOURSELF!
I hate to tell you this, but the bovine
leukemia virus is found in more than three of five dairy cows in the United
States! This involves about 80% of dairy herds. Unfortunately, when the milk
is pooled, a very large percentage of all milk produced is contaminated (90
to 95 per cent). Of course the virus is killed in pasteurisation--if the
pasteurisation was done correctly. What if the milk is raw? In a study of
randomly collected raw milk samples the bovine leukemia virus was recovered
from two-thirds. I sincerely hope that the raw milk dairy herds are carefully
monitored when compared to the regular herds. (Science 1981; 213:1014).
This is a world-wide problem. One lengthy
study from Germany deplored the problem and admitted the impossibility of
keeping the virus from infected cows' milk from the rest of the milk. Several
European countries, including Germany and Switzerland, have attempted to
"cull" the infected cows from their herds. Certainly the United
States must be the leader in the fight against leukemic dairy cows, right?
Wrong! We are the worst in the world with the former exception of Venezuela
according to Virgil Hulse MD, a milk specialist who also has a B.S. in Dairy
Manufacturing as well as a Master's degree in Public Health.
As mentioned, the leukemia virus is rendered
inactive by pasteurisation. Of course. However, there can be Chernobyl like
accidents. One of these occurred in the Chicago area in April, 1985. At a
modern, large, milk processing plant an accidental "cross
connection" between raw and pasteurised milk occurred. A violent salmonella
outbreak followed, killing 4 and making an estimated 150,000 ill. Now the
question I would pose to the dairy industry people is this: "How can you
assure the people who drank this milk that they were not exposed to the
ingestion of raw, unkilled, bully active bovine leukemia viruses?"
Further, it would be fascinating to know if a "cluster" of leukemia
cases blossoms in that area in 1 to 3 decades. There are reports of
"leukemia clusters" elsewhere, one of them mentioned in the June
10, 1990 San Francisco Chronicle involving No. California.
What happens to other species of mammals when
they are exposed to the bovine leukemia virus? Its a fair question and the
answer is not reassuring. Virtually all animals exposed to the virus develop
leukemia. This includes sheep, goats, and even primates such as rhesus
monkeys and chimpanzees. The route of transmission includes ingestion (both
intravenous and intramuscular) and cells present in milk. There are obviously
no instances of transfer attempts to human beings, but we know that the virus
can infect human cells in vitro. There is evidence of human antibody
formation to the bovine leukemia virus; this is disturbing. How did the
bovine leukemia virus particles gain access to humans and become antigens?
Was it as small, denatured particles?
If the bovine leukemia viruses causes human
leukemia, we could expect the dairy states with known leukemic herds to have
a higher incidence of human leukemia. Is this so? Unfortunately, it seems to
be the case! Iowa, Nebraska, South Dakota, Minnesota and Wisconsin have
statistically higher incidence of leukemia than the national average. In
Russia and in Sweden, areas with uncontrolled bovine leukemia virus have been
linked with increases in human leukemia. I am also told that veterinarians
have higher rates of leukemia than the general public. Dairy farmers have
significantly elevated leukemia rates. Recent research shows lymphocytes from
milk fed to neonatal mammals gains access to bodily tissues by passing
directly through the intestinal wall.
An optimistic note from the University of
Illinois, Ubana from the Department of Animal Sciences shows the importance
of ones perspective. Since they are concerned with the economics of milk and
not primarily the health aspects, they noted that the production of milk was
greater in the cows with the bovine leukemia virus. However when the leukemia
produced a persistent and significant lymphocytosis (increased white blood
cell count), the production fell off. They suggested
a need to re-evaluate
the economic impact of bovine leukemia virus infection on the dairy
industry. Does this mean that leukemia is good for profits only if we can
keep it under control? You can get the details on this business concern from
Proc. Nat. Acad. Sciences, U.S. Feb. 1989. I added emphasis and am insulted
that a university department feels that this is an economic and not a human
health issue. Do not expect help from the Department of Agriculture or the
universities. The money stakes and the political pressures are too great.
Youre on you own.
What does this all mean? We know that virus
is capable of producing leukemia in other animals. Is it proven that it can
contribute to human leukemia (or lymphoma, a related cancer)? Several
articles tackle this one:
1.Epidemiologic
Relationships of the Bovine Population and Human Leukemia in Iowa. Am
Journal of Epidemiology 112 (1980): 80
2.Milk of Dairy Cows Frequently Contains a Leukemogenic Virus. Science 213
(1981): 1014 3.Beware of the Cow.
(Editorial) Lancet 2 (1974):30
4.Is Bovine Milk A Health Hazard?. Pediatrics; Suppl. Feeding the Normal
Infant. 75:182-186; 1985
In Norway, 1422 individuals were followed for
11 and a half years. Those drinking 2 or more glasses of milk per day had 3.5
times the incidence of cancer of the lymphatic organs. British Med. Journal
61:456-9, March 1990.
One of the more thoughtful articles on this
subject is from Allan S. Cunningham of Cooperstown, New York. Writing in the
Lancet, November 27, 1976 (page 1184), his article is entitled, Lymphomas
and Animal-Protein Consumption. Many people think of milk as liquid meat
and Dr. Cunningham agrees with this. He tracked the beef and dairy
consumption in terms of grams per day for a one year period, 1955-1956., in
15 countries . New Zealand, United States and Canada were highest in that
order. The lowest was Japan followed by Yugoslavia and France. The difference
between the highest and lowest was quite pronounced: 43.8 grams/day for New
Zealanders versus 1.5 for Japan. Nearly a 30-fold difference!
(Parenthetically, the last 36 years have seen a startling increase in the
amount of beef and milk used in Japan and their disease patterns are
reflecting this, confirming the lack of genetic protection seen in
migration studies. Formerly the increase in frequency of lymphomas in
Japanese people was only in those who moved to the USA)!
An interesting bit of trivia is to note the
memorial built at the Gyokusenji Temple in Shimoda, Japan. This marked the
spot where the first cow was killed in Japan for human consumption! The
chains around this memorial were a gift from the US Navy. Where do you
suppose the Japanese got the idea to eat beef? The year? 1930.
Cunningham found a highly significant
positive correlation between deaths from lymphomas and beef and dairy
ingestion in the 15 countries analysed. A few quotations from his article
follow:
The average intake of protein in many
countries is far in excess of the recommended requirements. Excessive
consumption of animal protein may be one co-factor in the causation of
lymphomas by acting in the following manner. Ingestion of certain proteins
results in the adsorption of antigenic fragments through the gastrointestinal
mucous membrane.
This results in chronic stimulation of
lymphoid tissue to which these fragments gain access
Chronic immunological
stimulation causes lymphomas in laboratory animals and is believed to cause
lymphoid cancers in men
The gastrointestinal mucous membrane is only a
partial barrier to the absorption of food antigens, and circulating
antibodies to food protein is commonplace especially potent lymphoid
stimulants. Ingestion of cows milk can produce generalized lymphadenopathy,
hepatosplenomegaly, and profound adenoid hypertrophy. It has been
conservatively estimated that more than 100 distinct antigens are released by
the normal digestion of cows milk which evoke production of all antibody
classes [This may explain why pasteurized, killed viruses are still antigenic
and can still cause disease.
Heres more. A large prospective study from
Norway was reported in the British Journal of Cancer 61 (3):456-9, March
1990. (Almost 16,000 individuals were followed for 11 and a half years). For
most cancers there was no association between the tumour and milk ingestion.
However, in lymphoma, there was a strong positive association. If one drank
two glasses or more daily (or the equivalent in dairy products), the odds
were 3.4 times greater than in persons drinking less than one glass of
developing a lymphoma.
There are two other cow-related diseases that
you should be aware of. At this time they are not known to be spread by the
use of dairy products and are not known to involve man. The first is bovine
spongiform encephalopathy (BSE), and the second is the bovine
immunodeficiency virus (BIV). The first of these diseases, we hope, is
confined to England and causes cavities in the animal's brain. Sheep have
long been known to suffer from a disease called scrapie. It seems to have
been started by the feeding of contaminated sheep parts, especially brains,
to the British cows. Now, use your good sense. Do cows seem like carnivores?
Should they eat meat? This profit-motivated practice backfired and bovine
spongiform encephalopathy, or Mad Cow Disease, swept Britain. The disease
literally causes dementia in the unfortunate animal and is 100 per cent
incurable. To date, over 100,000 cows have been incinerated in England in
keeping with British law. Four hundred to 500 cows are reported as infected
each month. The British public is concerned and has dropped its beef
consumption by 25 per cent, while some 2,000 schools have stopped serving
beef to children. Several farmers have developed a fatal disease syndrome
that resembles both BSE and CJD (Creutzfeldt-Jakob-Disease). But the British
Veterinary Association says that transmission of BSE to humans is
"remote."
The USDA agrees that the British epidemic was
due to the feeding of cattle with bonemeal or animal protein produced at
rendering plants from the carcasses of scrapie-infected sheep. The have
prohibited the importation of live cattle and zoo ruminants from Great
Britain and claim that the disease does not exist in the United States.
However, there may be a problem. "Downer cows" are animals who
arrive at auction yards or slaughter houses dead, trampled, lacerated,
dehydrated, or too ill from viral or bacterial diseases to walk. Thus they
are "down." If they cannot respond to electrical shocks by walking,
they are dragged by chains to dumpsters and transported to rendering plants
where, if they are not already dead, they are killed. Even a
"humane" death is usually denied them. They are then turned into
protein food for animals as well as other preparations. Minks that have been
fed this protein have developed a fatal encephalopathy that has some
resemblance to BSE. Entire colonies of minks have been lost in this manner,
particularly in Wisconsin. It is feared that the infective agent is a prion
or slow virus possible obtained from the ill "downer cows."
The British Medical Journal in an editorial
whimsically entitled "How Now Mad Cow?" (BMJ vol. 304, 11 Apr.
1992:929-30) describes cases of BSE in species not previously known to be
affected, such as cats. They admit that produce contaminated with bovine
spongiform encephalopathy entered the human food chain in England between
1986 and 1989. They say. "The result of this experiment is
awaited." As the incubation period can be up to three decades, wait we
must.
The immunodeficency virus is seen in cattle
in the United States and is more worrisome. Its structure is closely related
to that of the human AIDS virus. At this time we do not know if exposure to
the raw BIV proteins can cause the sera of humans to become positive for HIV.
The extent of the virus among American herds is said to be widespread. (The
USDA refuses to inspect the meat and milk to see if antibodies to this
retrovirus is present). It also has no plans to quarantine the infected
animals. As in the case of humans with AIDS, there is no cure for BIV in
cows. Each day we consume beef and diary products from cows infected with
these viruses and no scientific assurance exists that the products are safe.
Eating raw beef (as in steak Tartare) strikes me as being very risky,
especially after the Seattle E. coli deaths of 1993.
A report in the Canadian Journal of
Veterinary Research , October 1992, Vol. 56 pp.353-359 and another from the
Russian literature, tell of a horrifying development. They report the first
detection in human serum of the antibody to a bovine immunodeficiency virus
protein. In addition to this disturbing report, is another from Russia
telling us of the presence of virus proteins related to the bovine leukemia
virus in 5 of 89 women with breast disease (Acta Virologica Feb. 1990 34(1):
19-26). The implications of these developments are unknown at present.
However, it is safe to assume that these animal viruses are unlikely to
stay in the animal kingdom.
OTHER CANCERS--DOES IT GET WORSE?
Unfortunately it does. Ovarian cancer--a
particularly nasty tumour--was associated with milk consumption by workers at
Roswell Park Memorial Institute in Buffalo, New York. Drinking more than one
glass of whole milk or equivalent daily gave a woman a 3.1 times risk over
non-milk users. They felt that the reduced fat milk products helped reduce
the risk. This association has been made repeatedly by numerous
investigators.
Another important study, this from the
Harvard Medical School, analyzed data from 27 countries mainly from the
1970s. Again a significant positive correlation is revealed between ovarian
cancer and per capita milk consumption. These investigators feel that the
lactose component of milk is the responsible fraction, and the digestion of
this is facilitated by the persistence of the ability to digest the lactose
(lactose persistence) - a little different emphasis, but the same conclusion.
This study was reported in the American Journal of Epidemiology 130 (5):
904-10 Nov. 1989. These articles come from two of the countrys leading
institutions, not the Rodale Press or Prevention Magazine.
Even lung cancer has been associated with
milk ingestion? The beverage habits of 569 lung cancer patients and 569
controls again at Roswell Park were studied in the International Journal of
Cancer, April 15, 1989. Persons drinking whole milk 3 or more times daily had
a 2-fold increase in lung cancer risk when compared to those never drinking
whole milk.
For many years we have been watching the lung
cancer rates for Japanese men who smoke far more than American or European
men but who develop fewer lung cancers. Workers in this research area feel
that the total fat intake is the difference.
There are not many reports studying an
association between milk ingestion and prostate cancer. One such report
though was of great interest. This is from the Roswell Park Memorial
Institute and is found in Cancer 64 (3): 605-12, 1989. They analyzed the
diets of 371 prostate cancer patients and comparable control subjects:
Men who reported drinking three or more
glasses of whole milk daily had a relative risk of 2.49 compared with men who
reported never drinking whole milk
the weight of the evidence appears to
favour the hypothesis that animal fat is related to increased risk of prostate
cancer. Prostate cancer is now the most common cancer diagnosed in US men and
is the second leading cause of cancer mortality.
WELL, WHAT ARE THE BENEFITS?
Is there any health reason at all for an
adult human to drink cows' milk?
It's hard for me to come up with even one
good reason other than simple preference. But if you try hard, in my opinion,
these would be the best two: milk is a source of calcium and it's a source of
amino acids (proteins).
Let's look at the calcium first. Why are we
concerned at all about calcium? Obviously, we intend it to build strong bones
and protect us against osteoporosis. And no doubt about it, milk is loaded
with calcium. But is it a good calcium source for humans? I think not. These
are the reasons. Excessive amounts of dairy products actually interfere with
calcium absorption. Secondly, the excess of protein that the milk provides is
a major cause of the osteoporosis problem. Dr. Hegsted in England has been
writing for years about the geographical distribution of osteoporosis. It
seems that the countries with the highest intake of dairy products are
invariably the countries with the most osteoporosis. He feels that milk is a
cause of osteoporosis. Reasons to be given below.
Numerous studies have shown that the level of
calcium ingestion and especially calcium supplementation has no effect
whatever on the development of osteoporosis. The most important such article
appeared recently in the British Journal of Medicine where the long arm of
our dairy industry can't reach. Another study in the United States actually
showed a worsening in calcium balance in post-menopausal women given three
8-ounce glasses of cows' milk per day. (Am. Journal of Clin. Nutrition,
1985). The effects of hormone, gender, weight bearing on the axial bones, and
in particular protein intake, are critically important. Another observation
that may be helpful to our analysis is to note the absence of any recorded
dietary deficiencies of calcium among people living on a natural diet without
milk.
For the key to the osteoporosis riddle, dont
look at calcium, look at protein. Consider these two contrasting groups.
Eskimos have an exceptionally high protein intake estimated at 25 percent of
total calories. They also have a high calcium intake at 2,500 mg/day. Their
osteoporosis is among the worst in the world. The other instructive group are
the Bantus of South Africa. They have a 12 percent protein diet , mostly
plant protein, and only 200 to 350 mg/day of calcium, about half our womens
intake. The women have virtually no osteoporosis despite bearing six or more
children and nursing them for prolonged periods! When African women immigrate
to the United States, do they develop osteoporosis? The answer is yes, but
not quite are much as Caucasian or Asian women. Thus, there is a genetic
difference that is modified by diet.
To answer the obvious question, "Well,
where do you get your calcium?" The answer is: "From exactly the
same place the cow gets the calcium, from green things that grow in the
ground," mainly from leafy vegetables. After all, elephants and rhinos
develop their huge bones (after being weaned) by eating green leafy plants,
so do horses. Carnivorous animals also do quite nicely without leafy plants.
It seems that all of earth's mammals do well if they live in harmony with
their genetic programming and natural food. Only humans living an affluent
life style have rampant osteoporosis.
If animal references do not convince you,
think of the several billion humans on this earth who have never seen cows
milk. Wouldnt you think osteoporosis would be prevalent in this huge group?
The dairy people would suggest this but the truth is exactly the opposite.
They have far less than that seen in the countries where dairy products are
commonly consumed. It is the subject of another paper, but the truly
significant determinants of osteoporosis are grossly excessive protein
intakes and lack of weight bearing on long bones, both taking place over
decades. Hormones play a secondary, but not trivial role in women. Milk is a
deterrent to good bone health.
THE PROTEIN MYTH
Remember when you were a kid and the adults
all told you to make sure you get plenty of good protein. Protein was the
nutritional good guy when I was young. And of course milk is fitted right
in.
As regards protein, milk is indeed a rich
source of protein--"liquid meat," remember? However that isn't
necessarily what we need. In actual fact it is a source of difficulty. Nearly
all Americans eat too much
protein.
For this information we rely on the most
authoritative source that I am aware of. This is the latest edition (1oth,
1989: 4th printing, Jan. 1992) of the Recommended Dietary Allowances
produced by the National Research Council. OF interest, the current editor of
this important work is Dr. Richard Havel of the University of California in
San Francisco. First to be noted is that the recommended protein has been
steadily revised downward in successive editions. The current recommendation
is 0.75 g/kilo/day for adults 19 through 51 years. This, of course, is only
45 grams per day for the mythical 60 kilogram adult. You should also know
that the WHO estimated the need for protein in adults to by .6g/kilo per day.
(All RDA's are calculated with large safety allowances in case you're the
type that wants to add some more to "be sure.") You can "get
by" on 28 to 30 grams a day if necessary!
Now 45 grams a day is a tiny amount of
protein. That's an ounce and a half! Consider too, that the protein does not
have to be animal protein. Vegetable protein is identical for all practical
purposes and has no cholesterol and vastly less saturated fat. (Do not be
misled by the antiquated belief that plant proteins must be carefully
balanced to avoid deficiencies. This is not a realistic concern.) Therefore
virtually all Americans, Canadians, British and European people are in a
protein overloaded state. This has serious consequences when maintained over
decades. The problems are the already mentioned osteoporosis, atherosclerosis
and kidney damage. There is good evidence that certain malignancies, chiefly
colon and rectal, are related to excessive meat intake. Barry Brenner, an
eminent renal physiologist was the first to fully point out the dangers of
excess protein for the kidney tubule. The dangers of the fat and cholesterol
are known to all. Finally, you should know that the protein content of human
milk is amount the lowest (0.9%) in mammals.
IS THAT ALL OF THE TROUBLE?
Sorry, there's more. Remember lactose? This
is the principal carbohydrate of milk. It seems that nature provides
new-borns with the enzymatic equipment to metabolize lactose, but this
ability often extinguishes by age 4 or 5 years.
What is the problem with lactose or milk
sugar? It seems that it is a disaccharide which is too large to be absorbed
into the blood stream without first being broken down into monosaccharides,
namely galactose and glucose. This requires the presence of an enzyme,
lactase plus additional enzymes to break down the galactose into glucose.
Lets think about his for a moment. Nature
gives us the ability to metabolize lactose for a few years and then shuts off
the mechanism. Is Mother Nature trying to tell us something? Clearly all
infants must drink milk. The fact that so many adults cannot seems to be
related to the tendency for nature to abandon mechanisms that are not needed.
At least half of the adult humans on this earth are lactose intolerant. It
was not until the relatively recent introduction of dairy herding and the ability
to borrow milk from another group of mammals that the survival advantage of
preserving lactase (the enzyme that allows us to digest lactose) became
evident. But why would it be advantageous to drink cows milk? After all,
most of the human beings in the history of the world did. And further, why
was it just the white or light skinned humans who retained this knack while
the pigmented people tended to lose it?
Some students of evolution feel that white
skin is a fairly recent innovation, perhaps not more than 20,000 or 30,000
years old. It clearly has to do with the Northward migration of early man to
cold and relatively sunless areas when skins and clothing became available.
Fair skin allows the production of Vitamin D from sunlight more readily than
does dark skin. However, when only the face was exposed to sunlight that area
of fair skin was insufficient to provide the vitamin D from sunlight. If
dietary and sunlight sources were poorly available, the ability to use the
abundant calcium in cows milk would give a survival advantage to humans who
could digest that milk. This seems to be the only logical explanation for
fair skinned humans having a high degree of lactose tolerance when compared
to dark skinned people.
How does this break down? Certain racial
groups, namely blacks are up to 90% lactose intolerant as adults. Caucasians
are 20 to 40% lactose intolerant. Orientals are midway between the above two
groups. Diarrhea, gas and abdominal cramps are the results of substantial
milk intake in such persons. Most American Indians cannot tolerate milk. The
milk industry admits that lactose intolerance plays intestinal havoc with as
many as 50 million Americans. A lactose-intolerance industry has sprung up
and had sales of $117 million in 1992 (Time May 17, 1993.)
What if you are lactose-intolerant and lust
after dairy products? Is all lost? Not at all. It seems that lactose is
largely digested by bacteria and you will be able to enjoy your cheese
despite lactose intolerance. Yogurt is similar in this respect. Finally, and
I could never have dreamed this up, geneticists want to splice genes to alter
the composition of milk (Am J Clin Nutr 1993 Suppl 302s).
One could quibble and say that milk is
totally devoid of fibre content and that its habitual use will predispose to
constipation and bowel disorders.
The association with anemia and occult
intestinal bleeding in infants is known to all physicians. This is chiefly
from its lack of iron and its irritating qualities for the intestinal mucosa.
The pediatric literature abounds with articles describing irritated
intestinal lining, bleeding, increased permeability as well as colic,
diarrhea and vomiting in cows milk-sensitive babies. The anemia gets a
double push by loss of blood and iron as well as deficiency of iron in the
cows milk. Milk is also the leading cause of childhood allergy.
LOW FAT
One additional topic: the matter of "low
fat" milk. A common and sincere question is: "Well, low fat milk is
OK, isn't it?"
The answer to this question is that low fat
milk isn't low fat. The term "low fat" is a marketing term used to
gull the public. Low fat milk contains from 24 to 33% fat as calories! The 2%
figure is also misleading. This refers to weight. They don't tell you that,
by weight, the milk is 87% water!
Well, then, kill-joy surely you must approve
of non-fat milk! I hear this quite a bit. (Another constant concern is:
What do you put on your cereal?) True, there is little or no fat, but now
you have a relative overburden of protein and lactose. It there is something
that we do not need more of it is another simple sugar-lactose, composed of
galactose and glucose. Millions of Americans are lactose intolerant to boot,
as noted. As for protein, as stated earlier, we live in a society that
routinely ingests far more protein than we need. It is a burden for our
bodies, especially the kidneys, and a prominent cause of osteoporosis.
Concerning the dry cereal issue, I would suggest soy milk, rice milk or
almond milk as a healthy substitute. If you're still concerned about calcium,
"Westsoy" is formulated to have the same calcium concentration as
milk.
SUMMARY
To my thinking, there is only one valid
reason to drink milk or use milk products. That is just because we simply
want to. Because we like it and because it has become a part of our culture.
Because we have become accustomed to its taste and texture. Because we like
the way it slides down our throat. Because our parents did the very best they
could for us and provided milk in our earliest training and conditioning.
They taught us to like it. And then probably the very best reason is
ICE
CREAM! Ive heard it described
to die for.
I had one patient who did exactly that. He
had no obvious vices. He didnt smoke or drink, he didnt eat meat, his diet
and lifestyle was nearly a perfectly health promoting one; but he had a
passion. You guessed it, he loved rich ice cream. A pint of the richest would
be a lean days ration for him. On many occasions he would eat an entire
quart - and yes there were some cookies and other pastries. Good ice cream
deserves this after all. He seemed to be in good health despite some expected
middle age spread when he had a devastating stroke which left him
paralyzed, miserable and helpless, and he had additional strokes and died several
years later never having left a hospital or rehabilitation unit. Was he old?
I dont think so. He was in his 50s.
So don't drink milk for health. I am
convinced on the weight of the scientific evidence that it does not "do
a body good." Inclusion of milk will only reduce your diet's nutritional
value and safety.
Most of the people on this planet live very
healthfully without cows' milk. You can too.
It will be difficult to change; we've been
conditioned since childhood to think of milk as "nature's most perfect
food." I'll guarantee you that it will be safe, improve your health and
it won't cost anything. What can you lose?
