Nutrition generally refers to the science of consuming food to maintain health, promote growth, and provide energy. Nutrition has two main components: macronutrients and micronutrients. Macronutrients include carbohydrates, proteins, fats, and water, while micronutrients consist of vitamins and minerals.
To maintain a properly functioning body, a person needs to consume the appropriate amounts of these nutrients to support a healthy immune system and prevent diseases. Proper nutrition also plays a crucial role in maintaining healthy skin and overall well-being. A balanced diet containing all essential nutrients is vital for growth and the prevention of certain health conditions.
