A healthy diet includes a variety of foods that provide essential nutrients, such as vitamins, minerals, proteins, carbohydrates, and healthy fats. It typically emphasizes whole foods like fruits, vegetables, whole grains, lean proteins, and healthy fats, while limiting processed foods, added sugars, and excessive salt. This balanced approach helps maintain overall health and supports bodily functions. Incorporating a range of food groups ensures that the body receives the necessary nutrients for energy and growth. Drinking plenty of water and practicing portion control are also important aspects of a healthy diet. Following guidelines from organizations like the World Health Organization can help individuals make informed dietary choices.
