I agree with you doctor Delio Esteve was full of rubbish. What seemed strange to me is that doctor was bred as a vegan by his father. His father disapproved the intake of cow milk but the son recommends nowadays to take one litre of milk per day, at least. When I asked him for his father he told me this person have died and the doctor added that in the last days he have suffered rheumatism. Must I understand it was because of the lack of milk in his diet???.
