High content of proteins, diets low in carbohydrates with compound of Colon cancer

Persons after a high content of protein, low carbohydrate diet may be an increased risk of colon cancer, says a new study, due to changes in the colon.
High content of proteins, "low-carb" diets advocate eating foods heavy in saturated fat and Bacon, eggs, red meat and dairy products, but to avoid foods high in carbohydrates such as bread, pasta, cereals and fruits.
This is in contrast with the advice of traditional diet, recommended to eat less animal products and more fruits, vegetables and whole grains.
The study, published in the American Journal of Clinical Nutrition, researchers since 17 obese men on diets of tres-corto term.
The first diet was a plan of one week that allowed 360 grams of carbohydrate each day and includes food such as eggs and toast for breakfast; a sandwich and salad for lunch. and pasta with fish or soybean for dinner.
Number two, a four-week plan, diet allowed a lean 22 grams of carbohydrates per day; Bacon and eggs for breakfast; lunch and dinner consisted of foods high in meat, poultry, fish and some cheeses and vegetables.
The last of the diet, a "moderate-" carbohydrates, allowed only 181 grams of carbohydrate each day for four weeks; both diets of high protein biscuits amounted to less than 140 grams of protein every day.
After each diet, scientific fecal samples of men collected and analyzed the levels of specific metabolic by-products; find to eat a diet high in proteins, males had higher levels of N-nitrous, and other compounds related to cancer. In addition, samples showed lower levels of compounds that help reduce the risk of cancer.
However, scientists not sure how these results will affect health long term of a person, but they suggest be cautious before taking any diet that is low in dietary fiber. Meat does not contain fiber. Health experts recommend adults consume 28 grams of fiber a day.
Diets low in carbohydrates rose to fame in 1972 when Dr. Robert Atkins published Dr. Atkins diet revolution promote the consumption of foods with high content of fat for weight loss and challenging approach of low fat content.
Since then, many books have been written advocating meat more to improve health, claiming ancestors human were mainly hunters and mainly consume meat. But this opinion continues to be controversial and not accepted.
In previous years, the American Heart Association has cooled down in its criticism of low carbohydrate diets; recognition of low carbohydrate diets provide some benefit in the treatment of conditions such as metabolic syndrome.
