Diet and Eating Habits


The ubiquity of food in developed nations does not necessarily imply that people will choose healthy options, nor does the scarcity of food in some developing areas imply poor eating habits. RAND research on diet and eating habits investigates economic and social factors behind such concerns as diet choices, nutrition, access to foods, obesity, and weight loss.

    Regulators Should Insist Food Providers “First, Do No Harm”

    Everyone needs food, water, and shelter, yet society offers protective standards and regulations for just two of these three essentials. Food regulations focus on preventing illnesses like botulism, but when it comes to chronic diseases like obesity and diabetes, regulations offer little protection to U.S. consumers.

    Supermarkets Are the Problem

    Thirty percent of all supermarket sales can be attributed to end-of-aisle displays, where retailers have placed more foods that increase the risk of obesity and chronic diseases. Relocating those foods to less conspicuous places would still allow those who want them to get them, but the decision to buy would be deliberate rather than impulsive.

    In-Store Promotions and Obesity Risk: Is There a Connection?

    A close look at marketing tactics (like special displays and price cuts) in Pittsburgh "food deserts" revealed that stores allocate more price reductions to low-nutrient foods than to healthy choices. These strategies are associated with increased body mass among regular shoppers, but more research is needed to confirm a causal link to obesity.

    Calorie Labels Won't Fix America's Problem with Away-From-Home Food

    The FDA's new guidelines for calorie labeling on restaurant menus, retail establishments like convenience stores and movie theaters, and vending machines are a long-due recognition that eating away from home can be hazardous to health. But the new mandate falls far short of providing the necessary fix.

    Improved Access May Not Be the Key to Addressing Food Deserts

    As part of the ongoing battle to fight obesity in the U.S., current policies are aimed at improving access to healthy foods, especially in neighborhoods designated as food deserts. However, research indicates proximity to full-service supermarkets was unrelated to weight or dietary quality.

    With its Global Food Initiative, the University of California is seeking ways to help the billion people who go to bed hungry each night. At the same time, UC could also be addressing obesity. Experimenting with changes to the food environment and documenting their impact on diet and weight gain would accelerate progress on this national problem not just for students, but for all Americans.

    The problem of obesity cannot be attributed to a single dietary or physiological factor, like too much sugar, too much fat, or even factors like viruses, bacteria, and endocrine disrupters. The real problem is that Americans now live in a food swamp and there is just too much food easily available.
