Vitamins are nutrients that are required by the body in very small quantities. Vitamin D is important for healthy bones and teeth. If the body does not get sufficient amount of vitamin D, it leads to a deficiency disease called rickets in children. It results in softening and weakening of bones. In adults, deficiency of vitamin D causes another disease called osteomalacia.

Proteins, carbohydrates and fats are macronutrients. The word 'macro' means 'large scale'. These nutrients are required in large quantities and provide our body with energy. Vitamins and minerals are micronutrients. The word 'micro' means 'minute' so micronutrients are required in small quantities by the body. Each vitamin plays an important role in the body and not getting enough of them can cause health problems and diseases.
