Nutrition and its impact on health and performance are of crucial importance. Nutrition plays a significant role in one's life. "Good nutrition" encompasses more than preventing nutrient deficiencies or inadequacies related to diseases. It also forms the foundation of one's fitness, physical performance, and overall well-being. The scientific method offers a systematic, unbiased approach to evaluating the relationships between food and health or performance. Such an increase in societal interest creates opportunities for nutritional misinformation to flourish. According to the American Dietetic Association, the media are consumers' leading source of nutrition information, but news reports of nutrition research often provide inadequate depth for consumers to make wise decisions. The best means to evaluate claims of enhanced health and sports performance made by nutritional products or practices is to possess a good background in nutrition and a familiarity with the experimental process of high-quality research.
