Healthy food refers to items that provide essential nutrients, such as vitamins, minerals, and fiber, while being low in unhealthy fats, sugars, and sodium. Examples include fruits, vegetables, whole grains, lean proteins, and healthy fats like those found in nuts and avocados. These foods support overall well-being, help maintain a healthy weight, and reduce the risk of chronic diseases. Eating a balanced diet that includes a variety of healthy foods can improve energy levels and enhance mood. Incorporating Mediterranean diet principles, which emphasize fruits, vegetables, and whole grains, can also promote heart health and longevity.
