Nutrition standards are guidelines that help individuals and organizations understand the essential nutrients needed for a healthy diet. These standards are often developed by health authorities, such as the World Health Organization or U.S. Department of Agriculture, and provide recommendations on daily intake levels for vitamins, minerals, proteins, fats, and carbohydrates. These guidelines aim to promote overall health and prevent chronic diseases by encouraging balanced eating habits. By following nutrition standards, people can make informed food choices that support their well-being and help maintain a healthy weight, ultimately leading to a better quality of life.
