High-Protein, Low-Carb Diets Linked to Colon Cancer Compound

People following a high-protein, low-carbohydrate diet may be at higher risk of colon cancer, says a new study, due to changes in the colon.

High-protein, "low-carb" diets advocate eating foods heavy in saturated fat like bacon, eggs, red meat, and dairy, but avoiding high-carbohydrate foods, such as bread, pasta, grains, and fruit.

This is in stark contrast to traditional diet advice, which recommends eating fewer animal products and more fruits, vegetables, and whole grains.

For the study, published in the American Journal of Clinical Nutrition, researchers put 17 obese men on three-short term diets.

The first diet was a one week plan that allowed 360 grams of carbohydrates each day and included foods like eggs and toast for breakfast; a sandwich and salad for lunch; and pasta with fish or soy for dinner.

Diet number two, a four week plan, allowed a meager 22 grams of carbs per day; bacon and eggs for breakfast; lunch and dinner consisted of meals high in meat, poultry, fish, and some cheese and vegetables.

The last diet, a "moderate-carbohydrate" diet, allowed only 181 grams of carbs each day for four weeks; both high-protein diets totaled less than 140 grams of protein every day.

After each diet, scientist collected fecal samples from the men and analyzed levels of specific metabolic byproducts; finding when eating a high-protein diet, men had higher levels of N-nitroso, and other compounds linked to cancer. Additionally, samples showed lower levels of compounds that help reduce the risk of cancer.

However, the scientists aren't sure how these results will affect a person's long-term health, but suggest being cautious before adopting any diet that is so low in dietary fiber. Meat does not contain fiber. Health experts recommend adults consume 28 grams of fiber per day.

Low-carb diets climbed to fame in 1972 when Dr. Robert Atkins published Dr. Atkins Diet Revolution promoting the consumption of high-fat foods for weight-loss and challenging the low-fat approach.

Since then, many other books have been written advocating more meat for better health, claiming human ancestors were primarily hunters and consumed mostly meat. But this opinion remains controversial and not widely accepted.

In previous years, the American Heart Association has cooled in its criticism of low-carb diets; acknowledging low-carbohydrate diets offer some benefit in treating conditions like metabolic syndrome.

Link to high-protein, low carbohydrate diet colon cancer compounds

Higher risk of colon cancer have people following high-protein low-carb diet, says new study changes in the colon.

High-protein "low carb" diet food heavy Bacon, eggs, lean meat, dairy products, of like advocated avoiding high carbohydrate foods such as pasta grain fruit bread eating saturated fat is.

This is the advice with the traditional diets recommend eating as opposed to less animal products and more fruits, vegetables and whole grains.

Was published in the journal of the American clinical nutrition, researchers 17 obese men 3 putting short-term dieting.

First meal is 360 g for carbohydrate breakfast each day and included food such as eggs and toast permission was planning week; sandwich or salad lunch;-dinners of pasta, fish and soy beans.

Diet number 2, 4-week plan that allowed just 22 grams carbohydrate per day; breakfast of bacon and eggs. Configuration for lunch and dinner meat, poultry, fish and some cheese and vegetable diet.

Last 4 weeks daily 181 grams carbohydrates only allow the "moderate-carbohydrate" of diet therapy diet; both high protein-protein meal was less than 140 g daily.

Faeces samples from each diet scientists, men of collect and analyze levels of certain metabolic byproducts; find a high links to n-nitroso-protein meal to eat, but higher than the men and other compounds. In addition, sample showed lower levels of the compound to reduce the risk of cancer.

But the effect of the result of long term health of scholars who are not sure, but dietary fiber is very low, being cautious before adopting a diet is recommended. Include fiber in the meat. Health professional adults 28 grams we recommend use of fiber per day.

Low-carb diet and promote consumption of high fat foods of Dr. Robert Atkins Dr Atkins diet for weight loss fame rose low fat approach to challenging Revolution published in 1972.

Since human ancestors, primarily hunters, mainly meat consumption insisted on advocating more meat for better health has written many other books. And controversial this opinion, is still widely accepted.

In previous years, the American Heart Association, has cooled in criticism of the low-carb diet; offers to treat conditions such as low-carb diet metabolic syndrome admit several advantages.
