What Is Nutrition?
Nutrition is the science of how food affects the body’s health, energy, and overall function. It involves understanding how nutrients—like carbohydrates, proteins, fats, vitamins, and minerals—are absorbed, used, and stored by the body. Good nutrition supports growth, repair, immune function, and mental clarity, while poor nutrition can lead to fatigue, illness, and chronic disease. At its core, nutrition is about fueling your body with the right balance of foods to thrive physically, mentally, and emotionally.
