The Impact of Food Environment on Obesity Rates
The food environment plays a significant role in shaping obesity rates. Over the past 50 years, changes in the food environment in the US have coincided with a dramatic increase in obesity rates, suggesting a strong environmental influence. Highly processed, calorie-dense foods that are convenient and seductive play a major role in triggering overconsumption and sustaining hard-to-control eating behaviors.
