Ordinary Foods, Extraordinary Health Claims
"Mayonnaise helps protect women from strokes.""Eating two servings of raisins a day may help lower the risk of colon cancer.""…scientists are studying links between honey consumption and athletic performance.""…compounds present in…sunflower seeds…have been shown to offer…protection against heart disease and cancer, as well as a role in memory and cognitive function." These are just a few examples of the claims that certain foods can improve health. However, if you ate a single serving of the mayonnaise, raisins, honey, and sunflower seeds on a daily basis, you'd be downing 550 calories from those foods alone.
Does Health Dictate the Shopping List?"It quickly gets very silly, this message of, 'this much on a daily basis will do whatever,'" says Jeanne Goldberg, PhD, director of the Center on Nutrition Communication at Tufts University. But does it work? Do people buy x food because of the message that it can prevent y disease? It appears they do—at least to some degree. "The primary determinant of food selection is taste," says Dr. Goldberg. Typically, cost is second, followed by convenience. However, people respond erratically. They'll add new products to their diet based on health claims. But, if they don't like them, then they won't buy them again. Regardless, Dr. Goldberg says that the health benefit angle has at least pushed them to give it a shot, especially if they are worried about getting cancer or some other disease.
