Obesity prevention messages should not only focus on eating healthy, but also eating less food, finds a study from Brazil. According to the study, a high availability of healthy foods does not necessarily mean a low availability of unhealthy foods, i.e., people are not replacing the purchase of unhealthy foods with healthy foods. They, in fact, just eat more overall.
Among populations with low access to food, a higher diversity of available healthy foods was associated with a lower prevalence of underweight. As expected, households with higher incomes and education levels had greater dietary diversity.
