does a high-fat diet cause diabetes? (NO!!)

hpsnickers1

I have seen a couple of these articles lately. I am posting this link because I get tired of information getting so twisted around byt the media.

http://www.marksdailyapple.com/does-a-high-fat-diet-cause-type-2-diabetes/#more-22728

Mark explains the results very well. My father is on dialysis and dying and my older brother was diagnosed last year (hence my journey on MFP). So I don't take this kind of stuff lightly.

No need to respond. Please just read. I just want to cry when I see this stuff.

From article: "disease-promoting casein?". I stopped reading after this. While I agree that fat is far from proven to cause diabetes, casein gets thrown under a bus here with nothing to back up the claim. The pot is calling the kettle black.

It's not like this is coming completely out of left field. The rats in T. Colin Campbell's famous "China Study" were fed casein. It is the protein source that led him to make the declaration that animal protein causes cancer.

Controversies
AutismCasein has been documented to break down to produce the peptide casomorphin, an opioid that appears to act primarily as a histamine releaser.[13] Some research indicates this casomorphine aggravates the symptoms of autism.[14] A 2006 review of seven studies indicated although benefits were seen in all studies from the introduction of elimination diets (e.g., casein-free or gluten-free) in the treatment of autism spectrum disorders, none of the studies were performed in a manner to create an unbiased scientific opinion.[15] Preliminary data from the first and only double-blind randomized control trial of a gluten- and casein-free diet "indicated no statistically significant findings even though several parents reported improvement in their children."[16] Although research has shown high rates of use of complementary and alternative therapies (CAM) for children with autism, including gluten and/or casein exclusion diets,[citation needed] the evidence for efficacy of these diets is currently unsubstantiated.[17]

[A1/A2 beta caseinsFour casein proteins make up about 80% of the protein in cow's milk. One of the major caseins is beta-casein, of which there are several types, but "A1" and "A2" are the most common. According to Food Standards Australia New Zealand (FSANZ),[18] certain breeds of cows, such as Friesians, produce mostly A1 milk, whereas other breeds, such as Guernseys, as well as sheep and goats, produce mostly A2 milk.

FSANZ also reports despite some hypotheses that consumption of A2 milk "provides levels of protection to consumers from autism in children as well as schizophrenia, diabetes and heart disease", the scientific evidence for such claims is "very limited".[18] Additionally, the European Food Safety Authority carried out a literature review in 2009 concluding "a cause and effect relationship is not established between the dietary intake of BCM7, related peptides or their possible protein precursors and non-communicable diseases" (see A2 milk). Studies supporting these claims have had significant flaws, and the data are inadequate to guide autism treatment recommendations.[19]

Cancer - . Colin Campbell's The China Study (2006)one of the largest nutritional studies ever conducted, describes a direct correlation between casein administered to rats and the promotion of cancer cell growth when exposed to carcinogens. One group of rats was put on a 5% protein diet and another group on a 20% protein diet. Regardless of the amount of aflatoxin (a potent carcinogen) administered to these rats, none of the rats on 5% protein developed foci, precursors to cancerous cell growth, and every rat on 20% protein developed the pre-cancer foci. Other studies conducted by Dr. Campbell on humans confirmed this correlation between the amount of protein consumed and the promotion of cancerous cell growth. Basically, he discovered that cancer growth could be turned on and off by adjusting the amount of animal protein in the diet. When [20] A 2001 study suggests another milk protein, whey protein, but not casein, may play a protective role against colon tumors in rats.[21] According to a study from the Australian Dairy Council, casein has antimutagenic effects.[22]

Casein-free diet Main article: Gluten-free, casein-free diet
Casein has a molecular structure quite similar to that of gluten. Thus, some gluten-free diets are combined with casein-free diets and referred to as a gluten-free, casein-free diet. Casein is often listed as sodium caseinate, calcium caseinate or milk protein. These are often found in energy bars, drinks, and packaged goods. A small fraction of the population is allergic to casein.[23]

Altering the effects of polyphenolsA study of Charité Hospital in Berlin by Lorenzo et al., published in The European Heart Journal, showed adding milk to tea causes the casein to bind to the molecules in tea that cause the arteries to relax, especially a catechin molecule called EGCG, although a more recent study by Reddy et al. (2005) suggests the addition of milk to tea does not alter the antioxidant activity in vivo,[24] and the cardiovascular effect remains controversial.[25][26] A study published in the journal Free Radical Biology and Medicine indicates casein reduced the peak plasma levels of beneficial polyphenols after the consumption of blueberries.[citation needed]

Drug-casein interactionCaseinate salts have been shown to reduce the bioavailability of some drugs, including phenytoin. A patient on this drug should consult their doctor about altering their diet so that the efficacy of the drug is not diminished.[27]

Don't misunderstand me. I'm not saying that T. Colin Campbell's ultimate thesis is correct or that there aren't huge problems with his work. (If you know anything about the author of the blog post that started this thread, Denise Minger, you know that she is basically "internet famous" for coming out of nowhere and writing a huge blog post debunking a large portion of The China Study. So Ms. Minger isn't a China Study advocate herself, either.) I was simply noting that the idea of casein (by itself, not in milk) promoting cancer is not new and, I could be wrong, it does seem to be one of the few parts of his research that hasn't been refuted.

But, see, casein by itself isn't found in nature! It comes alongside whey, which is thought to have properties protecting against cancer. That is what is often so wrong with these lab studies is that they isolate nutrients in ways that nature does not and then make very large generalizations about those nutrients.

Right, and the OP's article treated it as if it was a well know fact. At least, that's how I read it. Hence, why I stopped reading.

Want casein protein without whey? Try cheese (Except ricotta, that's whey cheese without casein)

And I guess I thought that casein's cancer promoting properties *is* a relatively well-known fact -- at least to the typical reader of that blog. But you're right, she probably could have linked to some sources.

Yeah, but that's not how it came out of the cow (or goat, or whatever). There humans go again messing with stuff....
