Obesity, diabetes, and heart illness can be traced back to unbalanced diet plans. By eating a balanced diet full of essential nutrients, we can remarkably safeguard our body against these aliments.
Essential Nutrients for Health
Our body is a complex system that requires diverse nutrients in the right proportions for optimal functioning. There are six essential nutrients: carbohydrates, proteins, fats, vitamins, minerals, and water, each serving unique purposes.

Carbs are the body's primary source of energy. A deficiency can lead to fatigue, weakness, and difficulty concentrating. It can also cause constipation due to lack of dietary fiber.
Proteins are vital for the growth, repair, and maintenance of our body tissues. Inadequate protein intake can lead to muscle atrophy and a weakened immune system. Dietary sources of high-quality proteins include:
