Intense sweets taste especially good to some kids
Date:2/10/2010

PHILADELPHIA (February 10, 2010) New research from the Monell Center reports that children's response to intense sweet taste is related to both a family history of alcoholism and the child's own self-reports of depression.

The findings illustrate how liking for sweets differs among children based on underlying familial and biological factors.

"We know that sweet taste is rewarding to all kids and makes them feel good," said study lead author Julie A. Mennella, PhD, a developmental psychobiologist at Monell. "In addition, certain groups of children may be especially attracted to intense sweetness due to their underlying biology."

Because sweet taste and alcohol activate many of the same reward circuits in the brain, the researchers examined the sweet preferences of children with a genetic predisposition to alcoholism. They also studied the influence of depression, hypothesizing that children with depressive symptoms might have a greater affinity for sweets because sweets make them feel better.

In the study, published online in the journal Addiction, 300 children between 5 and 12 years of age tasted five levels of sucrose (table sugar) in water to determine their most preferred level of sweetness. The children also were asked questions to assess the presence of depressive symptoms, while their mothers reported information on family alcohol use.

Nearly half (49 percent) of the children had a family history of alcoholism, based on having a parent, sibling, grandparent, aunt or uncle who had received a diagnosis of alcohol dependence. Approximately one-quarter were classified as exhibiting depressive symptoms.

Liking for intense sweetness was greatest in the 37 children having both a positive family history of alcoholism and also reporting depressive symptoms. The most liked level of sweetness for these children was 24 percent sucrose, which is equivalent to about 14 teaspoons of sugar in a cup
