There is a widespread myth that we have to be careful about what we eat so that we do not cause protein deficiency. We know today that it is virtually impossible to design a calorie-sufficient diet, whether it is based on meat, fish, eggs, various vegetarian diets or even unprocessed whole natural plant foods, which is lacking in protein and any of the amino acids. The body is capable of taking incomplete proteins and making them complete by utilizing the amino acid recycling mechanism. The majority of amino acids absorbed from the intestinal tract are derived from recycled body protein. Research shows that high levels of animal protein intake may significantly increase the risk of premature mortality from all causes, among them cardiovascular diseases, cancer and type 2 diabetes.
