(Taubes; from an on-line source)
Although nutritionists dont like to talk about this in an era that considers fruits and vegetables to be the sine qua non of a healthful diet, animal products happen to contain all the amino acids, minerals and vitamins essential for health, with the only point of controversy being vitamin C. And the evidence suggests that the vitamin C content of meat products is more than sufficient for health, so long as the diet is indeed carbohydrate-restricted, absent the refined and easily digestible carbohydrates and sugars that would raise blood sugar and insulin levels and so increase our need to obtain vitamin C from the diet.
