Nutritional guidelines are recommendations designed to help individuals make healthy food choices. They provide information on the types and amounts of foods to consume for optimal health. These guidelines often emphasize a balanced diet that includes a variety of food groups, such as fruits, vegetables, whole grains, proteins, and healthy fats. Organizations like the World Health Organization and the U.S. Department of Agriculture create these guidelines based on scientific research. They aim to reduce the risk of chronic diseases, promote overall well-being, and support healthy growth and development in individuals of all ages.
