Toddlers with sweet tooth likely to gain weight

"Eating in the absence of hunger is associated with being overweight among older children, but this is the first time we've seen this link in children as young as toddlerhood," said one of the researchers Julie C. Lumeng, pediatrician at University of Michigan's C.S. Mott Children's Hospital in the US.

The findings of the study showed that children between one and three years old who reached for cookies over chips when their bellies were full had a higher risk increase in body fat. 

"We found that toddlers' eating sweet, but not salty, tasty foods after they already ate a filling meal puts children at a greater risk of weight gain," Lumeng explained.

Also, toddlers who ate more desserts and who became upset when the food was removed experienced gradual increase in body fat by the time they were 3- years old. 

However, those who picked the salty foods did not show any increase.

For the study, published in the forthcoming issue of journal Pediatrics, the researchers asked 209 low-income mothers to have each child fast for one hour before eating a substantial lunch. 

Toddlers were then presented with a tray of sweet treats like chocolate chip cookies and salty snacks like potato chips. 

They were allowed to eat as much as they wanted.

"The tendency to eat when you're not hungry increases with age and could have lifelong implications for weight gain," Lumeng noted.

The researchers suggested the need to explore ways to target this drive to eat before children even turn three.
