According to the Centers for Disease Control and Prevention, nearly four of every ten adults in the U.S. are obese. Among children, one in ten pre-schoolers are obese. Obesity and related illnesses are said to disproportionately affect poor and minority communities. One theory is that lack of access to healthy food makes it difficult for these families to maintain healthy weight. So-called food deserts, where few stores offer fresh produce or other healthy items, are commonly believed to keep people with low income from eating better. But new research says there could be another reason.
