ABSTRACT
This research investigated changes in blood cholesterol levels in children who participated in the national school lunch (L) or breakfast and lunch (BL) programs. Fasting blood samples were collected at baseline and 4 months from thirty, 11–15 year old children (16 L and 14 BL) who ate school meals three times/week. Regardless of the type of program, there was a statistically significant decrease in mean total cholesterol (p=0.001) and low-density lipoprotein cholesterol levels (p=0.007) from baseline to 4 months. Although breakfast and lunch meals served to the children were above the recommendations, decrease in blood cholesterol levels may be associated with hormones during puberty.
