Meat and Dairy Cause Cancer (T. Colin Campbell)

Alarming speech by Dr. Campbell (the China Study), who actually grew up on a dairy farm himself but became a vegan after seeing the results from his own research: animal products and their link to cancer.

A practically lone voice crying in the wilderness, it seems, considering the popularity of the low carb diets and the high consumption of animal products in general. We (and I include myself as a cheese lover) only want to hear what we want to hear, but the truth always comes out sooner or later.

Most people are aware of the connections between red and processed meats and cancer – that there is convincing evidence that these dangerous foods are a cause of colon cancer.1 In addition, cooking any meat at high temperatures (for example, grilled or fried chicken) forms carcinogenic compounds such as heterocyclic amines, which contribute to cancer risk.2,3 However, animal foods such as non-fat dairy products, egg whites, and fish are considered healthful by most people. It not yet widely recognized that foods such as these, since they are so high in animal protein, can also contribute to increased cancer risk.
When we consume animal protein, the body increases its production of a hormone called IGF-1, (insulin-like growth factor 1). IGF-1 is one of the body's important growth promoters during fetal and childhood growth, but later in life IGF-1 promotes the aging process. Reduced IGF-1 signaling in adulthood is associated with reduced oxidative stress, decreased inflammation, enhanced insulin sensitivity and longer lifespan.4 In contrast, IGF-1 has been shown to promote the growth, proliferation and spread of cancer cells, and elevated IGF-1 levels are linked to increased risk of several cancers, colon cancer included.5-8 Several observational studies have suggested that high circulating IGF-1 may translate into promotion of tumor growth in the colon. For example, one study in men and one another in women found that those with higher levels of IGF-1 had double the risk of colorectal ca ncers compared to those with lower levels.9,10
Which foods raise IGF-1?
Since the primary dietary factor that determines IGF-1 levels is animal protein, the excessive meat, fowl, seafood, and dairy intake common in our society elevates circulating IGF-1. Refined carbohydrates, like white flour, white rice, and sugars can also raise IGF-1 levels, because they cause rapid increases in insulin levels, leading to increases in IGF-1 signaling. In fact, IGF-1 signaling is thought to be a major factor in the connection between diabetes and cancer.11,12
It is the amino acid distribution of animal protein that sparks IGF-1 production.13 For this reason, isolated soy protein, found in protein powders and meat substitutes, may also be problematic because the protein is unnaturally concentrated and its amino acid profile is very similar to that of animal protein.
How can we keep IGF-1 in a safe range?
Reducing IGF-1 levels by dietary methods is now considered by many scientists to be an effective cancer prevention measure. Minimizing or avoiding animal protein, isolated soy protein and refined carbohydrates can help to keep our IGF-1 levels in a safe range. Green vegetables, beans and other legumes, and seeds are rich in plant protein and they have cancer-preventive, not cancer-promoting properties. For optimal cancer protection, vegetables, beans, fruits, intact grains, nuts and seeds should comprise the vast majority of our calories.

correlation != causation

Most people are aware of the connections between red and processed meats and cancer – that there is convincing evidence that these dangerous foods are a cause of colon cancer

But, if you're going to bring up associations:

Carbohydrates and colorectal cancer risk among Chinese in North America

These data indicate that increased eCarb (non-fiber carb) and total carbohydrate consumption are both associated with increased risk of colorectal cancer in both sexes, and that among women, relative risk appears greatest for the right colon, whereas among men, relative risk appears greatest for the rectum.

Dr. Joel Fuhrman, who is blinded by dietary dogma of his own (low fat vegetarian, dumb, dumb, dumb), at least gives a good critique of low carb diet myths in Eat to Live:

“So, it is certainly true – as the advocates of animal-food-rich diets, such as Atkins, Heller, Sears, and other proclaim – carbohydrates drive up insulin levels temporarily. These writers, however, have not presented the data in accurate fashion. A diet revolving around unrefined carbohydrates (fruits, vegetables, whole grains, and legumes) will not raise blood sugars or insulin levels. Studies have shown that such a diet can reduce fasting insulin levels 30-40 percent in just three weeks. Obviously, a low-fat diet that is high in refined sugars and refined carbohydrates and low in fiber is not a healthy diet. To lump refined and unrefined carbohydrates together is inaccurate and misleading.”

An expected part of aging in Western societies is to have the arteries feeding your heart, brain, legs, and penis close down by atherosclerosis. Yet these problems are almost never found in populations of people who follow a diet low in animal-derived and processed foods, such as those living in rural Asia, Africa, and Central and South America. The matter that clogs the arteries is living tissue (not concrete) and therefore, can heal given the right environment. To clean up your arteries (reverse atherosclerosis), a very low-fat, no-cholesterol diet must be followed strictly. Immediate benefits, such as relief of chest pains (angina) and tolerance for more exercise, are seen within days. Heart surgery fails to prolong life in the vast majority of people and is fraught with serious side effects, including permanent brain damage – don't go this route unless you have no other choice.

Processed foods, plant oils, fried foods

Processed foods, plant oils, fried foods, sugar and grains and meats cooked too well done cause all of the issues you mentioned. Properly raised and cooked meat, and dietary cholesterol are not the causes.

McDougall is a total train wreck.

name calling

is probably not the best way to start a discussion. it seems mcdougall mostly agrees with your man but sounds more knowledgeable on the subject.
http://drmcdougall.com/misc/2007nl/may/statins.htm

i know a couple who were very unhealthy, overweight and always going to the doctors. after attending a mcdougall seminar they decided they wanted to change. they followed his program and after a year i wouldn't have known it was the same two people, trim, tan, active and off all their meds. i'm sure they're not alone. why belittle someone who obviously has helped people just because it doesn't appeal to you?

i certainly agree that processed foods and fried foods are no good, as is overcooking, and i'd imagine most health minded folks would agree.

Also, it's not that McDougall "doesn't appeal" to me

Also, it's not that McDougall "doesn't appeal" to me. He has an abysmal understanding of cholesterol and gluten intolerance, among many other things. While some of what he says is good stuff, it is more than negated by the things where he's dead wrong.

Resist the temptation to feed the trolls.

I'm just being honest.

McDougall is a train wreck, and he doesn't look healthy. And he certainly is not more knowledgeable than Dr. Coldwell. Does Dr. Coldwell sound less knowledgeable to you because he's German, and English is his second language? If so, that is a shame.

I know a couple who have been doing McDougall for a long time. They look awful. They are thin, I'll grant that but they seem to be physically and mentally unhealthy. I've watched a couple of McDougall DVDs and get emails from him forwarded to me. Some of what he preaches is right on, some of it is not and some of it is toxic. Telling people to super-heat carbohydrates (potatoes in one case) in a teflon skillet is a recipe for disaster. Super-heating carbohydrates creates compounds that are toxic and super-heating the teflon skillet releases toxic compounds as well. This type of thing is why I say he's a train wreck. He knows just enough to be dangerous.

it had nothing to do with english

being his second language. maybe the couple you know are cheating and just eating vegan junk food, many do. mcdougall i believe was very unhealthy as a boy, overweight. i think he even had a heart attack and then changed his life with changing his eating, and would probably be dead had he not. i don't know about the teflon biz, but i found this:
http://www.drmcdougall.com/misc/2006nl/april/teflon.htm

personally i don't follow any one school but i try and learn from a variety
of nutritionists and i believe a lot of it is common sense.

"personally i don't follow..."

"personally i don't follow any one school but i try and learn from a variety of nutritionists and i believe a lot of it is common sense."

Same here.

That couple swears up and down that they stick with the McDougall diet strictly. Who knows. McDougall himself looks gray and unhealthy to me.

See, here's another thing. Everyone benefits from cleaning up their diet, as have I. What's different is what "cleaning up" means to different people. McDougall got rid of the vegetable oils, processed foods, etc. and got healthier. I think most all agree that lots of veggies in the diet is a good idea. He also got rid of meat and dairy, so he wrongly thinks that high carb is good and meat and dairy are bad. Many more people seem to be dairy intolerant than they think, so that may very well be a good thing for many to stay away from. I do. But he also wrongly blames the meat, chicken, fish etc. Again, one must understand the difference in steroid and antibiotic laden crap meat, processed junk meat, and organic, naturally raised and properly cooked meat. That's where he takes another wrong left turn.

Also, people are having more and more issues with candida overgrowth due to antibiotic use, steroids, birth control pills and a high sugar and...wait for it...high carbohydrate diet. And with more and more people becoming gluten intolerant, due to many issues but especially due to the hybridized, dwarf wheat strain that all of North America switched to in the 1980s, his high carb, high grain diet is a further recipe for disaster.

Resist the temptation to feed the trolls.

i think we agree

that nobody has all the answers. you may find this interesting.
http://experiencelife.com/article/paleo-vs-vegan/

That was really good.

That was really good. And maybe I missed something, but McDougall seemed kind of alone on the high carb, grains are great aspect. The other vegans were not hot on grains. Someone in there mentioned the current dwarf strain of wheat being bad news. McDougall must kind of be in denial regarding that wheat strain, and modern corn not being anything like what the ancient Mayans and Aztecs ate etc.

Everyone agrees that processed stuff of all kinds is bad. The Paleo folks were all against factory farm meats and pro wild game and fish and properly raised meats.

actually

i think greger confuses fuhrman with mcdougall since it is mcdougall not fuhrman who is down on nuts and seeds; seeds are even part of fuhrman's G-Bombs recommendation of slow burning micro-nutrients: greens,beans,onions, mushrooms, berries & seeds.

Not the meat and dairy products

its how it was raised, like a concentration camp, and having the animal eating poisonous crops.

We banned DDT many years ago and now roundup is more deadly but it is still being used. No wonder Monsanto needed immunity from Congress.

Broad Generalization

I'm on the blood type diet, and being blood type B, I do just fine digesting milk. One man's meat is another man's poison.

O's and A's would do better to avoid cow's milk. Stick to goat and sheep's milk. A's don't handle red meat very well, while O's lose muscle and get sick not having it.

This is another reason I don't want Congress governming what I eat. As a B, I'm in the minority.

Big difference from the meat at the grocery store

and grass feed beef. The store beef were fed loads of GMO crops, given lots of antibiotics to keep them from dying before slaughter. The poor cow has to live it whole life walking in its own manure. No animal can survive in a feed lot for more than two years they must slaughter them before 3 years of age.

If you continually eat sick animals your going to become as sick as they were. the ruminant was never intended to eat lots of grain. There is a good documentary out called franken beef that explains why they die off.

If you buy two steaks one from a grass fed beef the other from a fed lot, you will understand what is wrong. the fat content in the fed lot beef has a cake texture to it, I think it sticks to the inside of your mouth. The grass fed is a little tougher, has a slight game flavor but the fat is more translucent. It won't plug the arteries like the feed lot beef, can actually lower cholesterol.

I think we humans being a higher thinking beings need to start thinking of how our food was raised or treated humanly. We should all think about not buying from companies that house animals like concentration camps.
