FRIDAY, May 1 (HealthDay News) -- People with higher levels of education as well as income tend to eat healthier diets, but pay more for selecting foods that are less energy-dense (lower calorie/higher nutrient content), a U.S. study finds. Less energy-dense diets are associated with lower rates of obesity, class 2 diabetes, cardiovascular disease as well as some forms of cancer. Improving diet quality by lowering energy density is standard advice for weight control, cancer prevention as well as best health, according to the University of Washington researchers. Their study included 164 adults in the Seattle area who recorded their usual frequency of consumption of 152 foods as well as 22 beverages, along with portion sizes. They as well as provided four-day dietary records as well as completed demographic as well as behavioral questionnaires. The researchers found that higher dietary energy density was associated with higher intakes of total overweight as well as saturated overweight as well as lower intakes of dietary fiber, potassium as well as vitamins A as well as C. Daily diet cost was $6.72 per day for men as well as $6.21 per day for women, which reflects the fact that the men ate more than the women. But women spent $8.12 for each 2,000 kcal of dietary energy, compared with $7.43 for men. Diets with lower energy density as well as higher nutrient content were more costly than those with higher energy density as well as lower nutrient content. Higher quality diets were associated with higher household levels of education as well as income. Education was a more dominant factor than income. "The findings that higher-quality diets were consumed by women of higher [socioeconomic status] as well as more costly per 2,000 kcal has implications for epidemiologic studies of diet as well as chronic disease," concluded study authors Pablo Monsivais as well as Adam Drewnowski. "Nutritional epidemiology has historically been based on the premise that nutrient exposures are directly linked to health outcomes. But, nutritional status is as well as intimately linked to socioeconomic status, as well as the findings reported here raise the possibility that the higher monetary cost of nutritious diets may provide one explanation for these observations. Expected studies, based on more representative samples, will be needed to elucidate the connections between diet quality as well as diet cost across socioeconomic strata," they wrote. The study appears in the May issue of the Journal of the American Dietetic Association. -- Robert Preidt SOURCE: Journal of the American Dietetic Association, news release, May 1, 2009
