Dr. Mark Hyman explains why milk may be causing health problems. He
provides six reasons why milk should be avoided to maintain wellness.
Dr. Mark Hyman: Hi, this is Doctor Mark Hyman. Today I’m going to tell
you six reasons why you should avoid dairy. Got milk? Well these days it
seems like almost everybody does, celebrities, athletes, even former
President Clinton’s head of Health and Human Services, Donna Shalala are
all proud to wear the white milk mustache.
After
all, everybody knows that you need milk to be healthy, right? Not
necessarily. Sure, dairy is nature’s perfect food, but only if you’re a
calf. If that sounds shocking to you, it’s because very few people are
willing to tell the truth about dairy.
In fact, criticizing milk in America is like taking on motherhood, apple
pie or baseball, but that’s just what I’m about to do. Based on the
research and my experience in practicing medicine, I typically advise
most of my patients to avoid dairy products completely. I like ice cream
just as much as the next person, but as a scientist I have to look
honestly at what we know. In just a second I’ll explore the many ill
effects that are documented from eating dairy.
Now that advice flies in the face of the new “up to date” Food Pyramid
from the United States Department of Agriculture. Now the USDA’s Food
Pyramid recommends drinking three glass of milk a day. What’s wrong with
that? Well for one thing, it’s a recommendation that’s not based on
strict science. Some of the experts who helped create the pyramid
actually work for the dairy industry, which makes the US Department of
Agriculture recommendations reflect industry interest, not science or
our best interest.
In fact, Doctor Walter Willett, the second most cited scientist in all
of clinical medicine and the head of Nutrition at Harvard School of
Public Health is one of the most vocal critics of the US Food Pyramid.
He’s even called its guidelines quote “udderly ridiculous,” as in
u-d-d-e-r-l-y ridiculous. That’s not something a Harvard scientist says
lightly, but Doctor Willett’s right. The pyramid just isn’t based on key
scientific findings about health. Just take a look at some of the
pyramid’s recommendations and why I disagree with them.
One, consume a variety of foods within and among the basic food groups
while staying within your body’s energy needs. Sounds sensible, but
which food groups? If you choose dairy, meats, fats, and carbohydrates,
the perfect meal could be a cheeseburger, milkshake, fries with ketchup.
Let’s face it, tomatoes and potatoes are vegetables, right, and they’re
the two top vegetables eaten in America. Generic advice like that is
pretty meaningless and potentially harmful.
The second bit of advice is control your caloric intake to manage your
body weight. Again, sounds pretty good, but as I wrote in my book,
UltraMetabolism, even the best trained nutritionists and dieticians
cannot come close to correctly estimating their own caloric intake in a
day. And is it okay to consume all of my calories from cola or ice cream
as long as I stay within my caloric needs? Of course not, so this is
more useless advice.
Number three, they say increase intake of fruits and vegetables, whole
grains, non-fat or low-fat milk products. Well fruits and veggies and
whole grains are great, milk not so much; I’ll get back to that in a
minute.
Choose carbohydrates wisely, that’s the next bit of advice from the Food
Pyramid. Who could argue with that, but how do they define ‘wisely?’
The real advice should be to cut down sugar intake from a hundred and
eighty-five pounds per person per year, which is what we currently
consume, to less than a pound a year, to avoid flour products, except as
a treat, and stick to whole food carbohydrates like vegetables, fruits,
whole grains, beans, nuts, and seeds.
The next bit of advice is to choose to prepare foods with little salt.
Not bad advice, but what if not of the food you eat is packages or
processed foods that you don’t actually prepare and are full of salt?
Like most Americans who eat half their meals outside the homes, this
isn’t healthful. So a better recommendation would be to avoid packaged,
canned, processed, prepared, and fast foods unless you know exactly how
they’re made.
The next bit of advice was if you drink alcoholic beverages, do so in
moderation. Sounds goods, but if you’re usually drinking two bottles of
wine a night, then one seems like moderation. I don’t think that’s a
good suggestion. I think it’s better to limit your alcohol consumption
to half a drink a day or three glasses a week; that seems to have the
most benefit with the least risk.
The next tip is don’t eat unsafe foods. Well of course you shouldn’t
leave your egg salad in the hot sun or toss your salad with hands and
just handle raw chicken coated with salmonella, but the Food Pyramid
guidelines don’t mention pesticides, hormones, antibiotics, genetically
modified foods despite scientific evidence of their harm; shame on the
USDA.
You can now see why I have a big problem with the Food Pyramid. Mostly
its guidelines try to sound sensible while still protecting the interest
of the food industry, the agriculture industry, and all the lobbyists
paying for the elections of Congress. Everybody’s happy, right? Well I’m
not, and you shouldn’t be either. The public just isn’t served by the
watered down, confusing, useless pyramid. Worse, some of the
recommendations are downright harmful, like the one to drink more milk
and dairy products.
According to Doctor Walter Willett, who has done many of the studies and
reviewed this topic extensively, there are many reasons to pass up
milk, including one, milk doesn’t reduce bone fractures. Contrary to
popular belief, eating dairy has never been shown to reduce fracture
risk, but dairy may actually increase the risk of fractures by fifty
percent according to the large Nurses Health Study. Less dairy equals
better bones. Countries with the lowest rates of dairy and calcium
consumption, like those in Africa and Asia, have the lowest rates of
osteoporosis.
Next thing is that calcium isn’t a bone protective as we thought.
Studies of calcium supplementation have shown no benefit in reducing
fracture risk. Vitamin D, on the other hand, appears to be much more
important than calcium in preventing practices. Also, calcium may raise
cancer risk. Research shows that higher intakes of both calcium and
dairy products may increase a man’s risk of prostate cancer by thirty to
fifty percent. Plus, dairy consumption increases the body’s level of
insulin-like growth factor 1, a known cancer promoter.
Calcium has benefits that dairy doesn’t. Calcium supplements, but not
dairy products, may reduce the risk of colon cancer. And another problem
with dairy is that not everyone can stomach dairy. About seventy-five
percent or three quarters of the world’s population is genetically
unable to properly digest milk and other dairy products, a problem
called lactose intolerance.
So based on such findings, Doctor Walter Willett has come to some
important conclusions. One, everyone needs calcium, but probably not as
much as our government’s recommended daily allowance of fifteen hundred
milligrams a day.
Two, calcium probably doesn’t prevent broken bones. Few people in this
country are likely to reduce their fracture risk by getting more
calcium. Three, men may not want to take calcium supplements;
supplements of calcium and vitamin D may be reasonable for women. And
four, dairy may be unhealthy. Advocating dairy consumption may have
negative effects on health. Now this is from Doctor Walter Willett, not
me, so you should think about your next glass of milk.
If all of that isn’t enough to swear you off milk, there are a few other
scientific findings worth noting. First, the Federal Trade Commission
recently asked the USDA to look into the scientific basis of claims made
in their milk mustache ads. Their panel of scientists stated the truth
clearly. Number one, milk doesn’t benefit sports performance. Number
two, there’s no evidence that dairy is good for your bones or prevents
osteoporosis.
In fact, the animal protein in it may actually help cause bone loss.
Number three, dairy is linked to prostate cancer. Number four, it’s full
of saturated fat and it’s linked to heart disease. Number five, dairy
causes digestive problems for seventy-five percent of people with
lactose intolerance. And number six, dairy aggravates irritable bowel
syndrome. Simply put, the FTC asked the dairy industry ‘got proof,’ and
the answer was no. Plus, dairy may contribute to more health problems
like allergies, sinus issues, ear infections, type I diabetes, chronic
constipation, and anemia in children.
But what about raw milk, isn’t that a healthier form of dairy? Well not
really. Yes, raw, whole, organic milk eliminates some of the concerns,
like pesticides, hormones, antibiotics, and the effects of
homogenization and pasteurization, but to me these benefits don’t
outweigh dairy’s potential risk. From an evolutionary point of view,
milk is a strange food for humans. Until ten thousand years ago, we
didn’t domesticate animals, and we weren’t able to drink milk unless
some brave hunter gatherer milked a wild tiger or a buffalo.
Now most scientists agree that it’s better for us to get calcium,
potassium, protein, and fats from other sources, like whole plant foods,
vegetables, fruits, beans, whole grains, nuts, seeds, and seaweed,
great source of minerals. Convinced yet? Well here’s my advice for
dealing with dairy. If you want healthy bones, take vitamin D, don’t
rely on dairy.
Get your calcium from dark leafy vegetables, sesame tahini, sea
vegetables, or sardines or salmon with the bones in it. And try giving
up all dairy, and see how you feel after a few weeks. And if you can
tolerate dairy, only use raw organic dairy products, preferably
fermented products like yogurt or kefir.
Still got milk? I hope not. Remember, dairy is not crucial for good
health. I encourage you to go dairy-free and see what it does for you.
