Short answer: It doesn’t. There is no scientific evidence linking sugar consumption to hyperactivity.
If a child eats loads of candy, a hyperactive frenzy will follow, right? Actually, no. All of the studies done on this topic have found there is no link between sugar consumption and hyperactivity.
Dr. Mark Wolraich, chief of Developmental and Behavioral Pediatrics at Oklahoma University Health Sciences Center, says “sugar does not appear to affect behavior in children.”
It’s the parent’s expectations of these “sugar highs” that appear to cloud the way they view their child’s behavior, Wolraich said.
Sugar is often a staple at birthday parties, Halloween, and other times when children are likely to bounce off the walls. All of this energy is apparently due to kids just being excited or possibly being told they will get hyper, so they do. These instances reinforce the parent’s belief in the mythical “sugar high.” The placebo effect is a real thing.
Science first became interested in how sugar affected hyperactivity when the Feingold Diet became popular in 1973. The diet advocated removing of food additives, such as dyes and artificial flavors from children’s diets because they “could” lead to hyperactivity. Although the diet did not originally mention sugar, sugar was grouped into the food additives category, due to the belief that it affected behavior.
Do you think your children get hyper after eating sugar?
