Eating sugar is worse than eating nothing! In A History of Nutrition, Elmer McCollum cited experiments in which animals fed water alone lived substantially longer than those fed sugar and water. The body requires certain nutrients to metabolize the sugar you eat, including B vitamins, calcium, magnesium, chromium, and zinc. Refined sugar does not contain these nutrients, so the body robs them from your reserves, which creates deficiencies and throws the body out of balance, creating disease. The purpose of food is to supply nutrients, but sugar robs you of nutrients.
