Marxist vs cultural and educational approaches of healthy eating

"The results indicate that healthier food consumption patterns may have an associated time cost. In this study, healthier food consumption patterns, characterized by more frequent consumption of fruits and vegetables, less money spent on food away from home, and fewer visits to fast food restaurants, were all significantly associated with more time spent preparing, cooking, and cleaning up from meals. One interpretation of these findings is that time spent cooking at home is a prerequisite to achieving healthier food consumption patterns. Even the USDA’s Thrifty Food Plan (characterized by a healthy diet plan at the lowest cost) heavily relies on cooking at home, implying that home cooking is important for achieving higher diet quality at lower costs."
