“In the past 10 years, several studies have examined the effects of sugar on children’s behavior. Here are the aspects of the studies that make them credible:
1. Known quantities of sugar in the diets were studied.
2. The studies compared the effects of sugar with those of a placebo (a substance without any active ingredients).
3. The children, parents and researchers involved in the studies never knew which children were given which diets (this is known as a “double-blind” study and helps to prevent unconscious biases from affecting the results).
An analysis of the results of all these studies was published in the November 22, 1995, issue of the Journal of the American Medical Association. The researchers’ conclusions? Sugar in the diet did not affect the children’s behavior. The authors did point out, though, that the studies didn’t rule out completely that sugar might be having a slight effect on a small number of children.”
Of course you are right about Diabetes, and you forgot to mention tooth-decay.
