The quality of foods available in the home is largely influenced by grocery shopping behavior, use of non-home sources for family meals, and food preparation methods. Studies have shown that households with overweight individuals purchased foods higher in fat and calories than those with normal weight adults and that more frequent shopping is related to better diets.The frequency with which family meals are obtained from non-home sources, such as fast food, takeout, and delivery, also has implications for weight management and healthfulness of the home food environment. One study found that parents who reported at least 1 family dinner per week from 1 of these sources were significantly more likely to be overweight or obese than those who did not report these food sources. Although not linked to family meals per se, it is well-established that fast-food consumption is associated with body mass index (BMI) and unhealthy diets.
