What is proper nutrition?

Proper nutrition involves consuming a balanced diet that provides all the necessary nutrients required for optimal health and well-being. It includes macronutrients such as carbohydrates, proteins, and fats, as well as micronutrients such as vitamins and minerals. A balanced diet should consist of a variety of foods from all food groups, including fruits, vegetables, whole grains, lean proteins, and healthy fats.

When should we focus on proper nutrition?

Proper nutrition should be a lifelong focus, starting from infancy through old age. Good nutrition is essential during pregnancy and lactation, as well as during childhood and adolescence when growth and development occur. As we age, proper nutrition becomes even more critical to help prevent chronic diseases and maintain overall health and wellbeing.
