Nutrition is the science of how the body obtains and utilizes nutrients from food to maintain optimal health and function. A balanced diet, encompassing a variety of macronutrients (carbohydrates, proteins, and fats), micronutrients (vitamins and minerals), fiber, and adequate hydration, is fundamental for supporting bodily functions, promoting growth and repair, and preventing various diseases. A well-rounded dietary approach involves mindful eating, portion control, and adherence to specific dietary guidelines based on individual needs, lifestyle, and health goals.

Specialized diets, such as the Mediterranean, vegetarian, or ketogenic, cater to different preferences and health requirements. Nutritional supplements may be considered when dietary needs cannot be met through regular food consumption. It's crucial to consult with healthcare professionals or registered dietitians to create personalized nutrition plans that align with individual health conditions and objectives.
