What is nutrition and why is it important?

Nutrition is the study of how food and drink affect the body's health and growth. It's crucial because it provides essential nutrients for energy, immune function, cell repair, and overall physical and mental well-being, helping prevent chronic diseases.

What are the main types of nutrients?

The main types are macronutrients (carbohydrates, proteins, and fats, needed in large amounts for energy and growth) and micronutrients (vitamins and minerals, required in smaller amounts for various bodily functions).

How can I improve my daily nutritional intake?

Focus on a balanced diet rich in whole foods: plenty of fruits and vegetables, lean proteins, whole grains, and healthy fats. Limit processed foods, excessive sugar, and unhealthy fats. Hydration is also key.

Are nutritional supplements necessary for everyone?

For most healthy individuals consuming a balanced diet, supplements are not strictly necessary. However, certain groups (e.g., pregnant women, vegans, those with specific deficiencies) may benefit from targeted supplementation under professional guidance.
