Dr. Dean Ornish, one of the most famous cardiologists and nutritionists in the United States, as well as the inventor of the Ornish diet, also considered one of the best diets against cholesterol , for the second time rises to the chair to warn against a protein-based diet animals and fats of animal origin, underlining some studies, in part his own. He had already done it about a year ago, to speak out about him against the trend of high-protein diets. Now, however , the New York Times publishes a new article of his, in which Dr. Ornish warns of the danger of animal-based foods for our health and explains that the consumption of animal proteins and animal fats increase blood cholesterol. In summary, Dr. Ornish recalls and cites all the studies where the consumption of animal protein and fat has been linked to an increased risk of cardiovascular health and cholesterol.
True? False? Do animal proteins and fats raise cholesterol yes or no? Do they increase the risk of cancer, yes or no? What about the risks of cardiovascular problems?Personally I follow a varied diet, which also includes saturated fats and animal proteins, and I have never had cholesterol problems, for one thing, but my experience or experience as a guy or a guy or a thousand other people unfortunately is not enough to determine where the truth is.
I think Dr. Ornish is right, but not entirely.

Is it right to avoid high-protein diets and diets that lead to excessive consumption of animal fats, such as the ketogenic diet? Absolutely yes. Is it right to avoid all animal products and saturated fats? Not necessarily.
Dr. Ornish says our Western diet is full of sugars, fats and other things that are bad for us, and that we generally eat more than thirty or forty years ago. My impression is that we eat worse, not necessarily more.
In the studies conducted on animal protein consumption and cardiovascular risk, studies that now appear for the most part questionable in the way in which they were conducted, one of the major criticisms against these studies is the following:no studies have ever shed light on the type of animal protein and the type of saturated fat consumed . If I eat game I will not have the same health problems that I can have by eating intensively farmed chicken. A piece of Grana Padano is in no way comparable to a spoonful of light cream cheese from a nutritional point of view. No food is alike if we consider it only from the point of view of the food category to which it belongs. Otherwise there would be no difference between an apple and a jar of apricot jam: is it correct to say that it is fruit either way? Here, most of the experiments conducted say nothing about the quality of the foods that the sample of people studied chose
