This is a really interesting article, especially if you do the questionnaire at the bottom that attempts to determine your age expectancy.

However I wondered about the following question

Do you avoid fatty foods, and emphasize fresh fruits and vegetables?

High protein diets, and the combination of a high fat and protein diet, have been associated with increased risk of cancer of the breast, uterus, prostate, colon, pancreas and kidney. An important mechanism is that these foods can be inefficient sources of energy and cause excess oxygen radical formation. Of course, saturated fats also lead to obesity and its risks. On the other hand, diets which emphasize fruits and vegetables have been associated with significantly lower heart disease risk and better quality of life. For more information go to:

NIH's Live Healthier and Longer

If we are to reduce carbohydrates, what is there left to eat if we also keep protein and fat in check. There is a lack of consistency here.

Is this statement true ? what studies was it based on.
