Nutrition involves understanding how food impacts health, including dietetics, the professional practice of managing diet plans. Macronutrients (carbohydrates, proteins, fats) provide energy, while micronutrients (vitamins, minerals) support body functions. Metabolism refers to how our bodies process food into energy. Behavioral change involves adopting healthier eating habits, often supported by organizations like the American Dietetic Association. Precision Nutrition tailors diet plans to individual needs, while tools like MyFitnessPal help track intake. The Institute for Nutrition promotes applied research, and concepts like HAES focus on health without weight obsession. Chrono-nutrition considers meal timing, and experts like Dr. John Berardi and Dr. David Katz contribute to advances in nutrition science.
