title: Treatment approaches: food first for weight management and health.
abstract: Many genetic, environmental, behavioral, and cultural factors affect health. Diet is as vital as any of them for preventing disease and promoting well-being. We know that what we eat can lead to premature disability and mortality: to obesity, coronary heart disease, type 2 diabetes, degenerative arthritis, sleep apnea, and other illnesses. Now scientific evidence points to links between dietary patterns and illness. The study of these links is a new approach to understanding the role that diet plays in chronic disease. Initial studies include those on eating patterns and risk of colon cancer. More recently, researchers have investigated all-cause mortality and leading causes of chronic disease. Novel epidemiological approaches include factorial analysis to evaluate dietary patterns and cluster analysis to examine nutrient intake, gender, and weight status across food-pattern clusters. These methods work best within groups to identify major dietary patterns, but not necessarily ideal diets. They may also differ across population groups. The success of the Dietary Approaches to Stop Hypertension and Lyon Diet Heart studies supports the value of dietary pattern analysis. At the same time, the relative failure of single-nutrient studies underscores the need for new methodologies and directions in research.
