Vitamins

Vitamins are tiny nutrients that protect our body from various illnesses.

Vitamins 'B' and 'C' are water-soluble, which means they dissolve in water. Vitamins 'A', 'D', 'E', and 'K' are fat-soluble, which means they dissolve in fat.

Vitamin 'A' strengthens our night vision and saves us from night blindness. It also protects us from diseases. We can get vitamin 'A' from foods like fish, meat, eggs, dark green vegetables, fruits, nuts, carrots and oranges.

Vitamin 'B' helps in digestion. There are different types of vitamin 'B' like thiamine, riboflavin, niacin, biotin, and folic acid. We can find vitamin 'B' in green vegetables, fruits, bananas, milk, and meat.
