This leads him to a controversial conclusion: that the saturated fat in butter, cheese and meats does not contribute to the clogging of arteries — and in fact is beneficial in moderate amounts in the context of a healthy diet (lots of fruits, vegetables, whole grains and other fresh, unprocessed foods). His own diet attests to that. Along with fruits, vegetables and whole grains, he eats red meat several times a week and drinks whole milk daily. He cannot remember the last time he ate anything deep-fried. He has never used margarine, and instead scrambles eggs in butter every morning. He calls eggs one of nature’s most perfect foods, something he has been preaching since the 1970s, when the consumption of cholesterol-laden eggs was thought to be a one-way ticket to heart disease. “Eggs have all of the nine amino acids you need to build cells, plus important vitamins and minerals,” he said. “It’s crazy to just eat egg whites. Not a good practice at all.”
