The problem with doctor Delio Esteve was with the vegans. He is the president of the Asociacion Naturista Argentina, vegetarian people, which is an asociation created by his father, a not borne vegan. Delio Esteve warns nowadays to his devotees against not to drink cow milk. He, apparently, do not trust in whatsoever vegetarian food like a credible source of calcium. He says it is because of the phytic acid very common in veggies. To survive healthy a strict vegetarian diet you must take more than a litre of milk per day. He stresses it very strongly. He seemed to me like feeling guilty because the mistake of his father. He was raised as a strict vegan with a hidden hunger for proteins and calcium. I do not know the stature of the father but the son has scarcely more then 1,60 meters of high.
