Cereal and weight
Frequent cereal eaters tend to have healthier body weights – and that includes people who choose presweetened cereals. It's true of men. It's true of women. And it's true of kids.
A large study published in the Journal of the American Dietetic Association followed 2,000 American girls over a 10-year period. It found that girls who demonstrated a consistent cereal-eating pattern had healthier body weights and lower Body Mass Index (BMI) than those who did not. Frequency of breakfast consumption and cereal consumption declined with age, but girls who continued to eat cereal frequently maintained a healthier body weight through adolescence.
Ready-to-eat cereals, including presweetened cereals, also made significant nutrient contributions in the diets of the girls. Forty-one percent of the cereals consumed in the study were presweetened. Still, the number of days eating cereal – including presweetened cereal – remained predictive of lower BMI and higher nutrient intakes.5
A second study reported similar results. Cereal consumption was associated with better nutritional status and a lower likelihood of weight gain among adolescents.
This study found that although the frequency of breakfast eating declined with age, days on which the girls ate breakfast were associated with higher calcium and higher fiber intake.15
Another study found that breakfast consumption is associated with a lower body weight,6 especially when ready-to-eat cereals are consumed, while yet another study found that people who reported consuming a breakfast of ready-to-eat cereal had healthier body weights than those who consumed higher fat breakfasts.1
