Nutrition science is an important scientific discipline that is both researched and taught in universities. Its findings are published not only in scientific literature, but also in magazines, newspapers, books, articles, and social media. Professionals and non-professionals often discuss healthy nutrition on television. Healthy nutrition is crucial for achieving a high quality of life, establishing a healthy lifestyle, and preventing diseases. Raising awareness and providing training on food, nutrition, and health issues can improve public health. In education, the basic principle is to determine adequate and balanced nutrition and appropriate physical activity levels for protecting individual and public health. Adequate and balanced nutrition is achieved by consuming recommended amounts of energy and food elements, according to personal characteristics and within a diverse diet. The practice of evidence-based nutrition entails utilizing the most reliable and current nutritional evidence, in combination with clinical experience, to assist individuals in the prevention, management, or coping with physical, mental, and social issues. This practice requires searching for and understanding clinical research, evidence, and nutrition.
