Camp food is just one of the summertime nutrition challenges for parents these days. While childhood health advocates often blame schools for poor nutrition and a lack of physical activity, the problem often gets worse in the summer. Last year, The American Journal of Public Health published a provocative study showing that schools may be taking too much of the blame for the childhood obesity epidemic.

Data from kindergarteners and first graders found that body mass index increased two to three times as fast in summer as during the regular school year. Minority children were especially vulnerable, as were children who were already overweight.
