TL;DR: This economic framework provides an explanation for the observed links between socioeconomic variables and obesity when taste, dietary energy density, and diet costs are used as intervening variables.

TL;DR: If higher SES is a causal determinant of diet quality, then the reported associations between diet quality and better health may have been confounded by unobserved indexes of social class, and some current strategies for health promotion, based on recommending high-cost foods to low-income people, may prove to be wholly ineffective.

TL;DR: Data from Asian nations, where diet structure is rapidly changing, suggest that diets higher in fats and sweeteners are also more diverse and more varied, and may be governed not by physiological mechanisms but by the amount of fat available in the food supply.

TL;DR: Dietary phytonutrients found in vegetables and fruit appear to lower the risk of cancer and cardiovascular disease, but some have long been viewed as plant-based toxins and pose a dilemma for the designers of functional foods.

TL;DR: Suggested research priorities are patient retention, natural history, assessment of intake and expenditure, obesity phenotypes, adolescence at a critical period, behavioral preference-reinforcement value, physical activity and social support, better linkage of new conceptual models to behavioral treatments, and the interface between pharmacological and behavioral methods.
