Each food group contributes uniquely to overall health. Fruits and vegetables provide essential vitamins, minerals, and antioxidants that support immune function and reduce disease risk. Whole grains are rich in fiber, promoting digestive health and stabilizing blood sugar levels. Lean proteins, like fish and legumes, help build and repair tissues while supporting muscle health. Healthy fats, such as those from nuts and avocados, contribute to brain health and hormone regulation. A balanced diet incorporating all food groups ensures that individuals obtain a wide array of nutrients necessary for optimal well-being.
