Vitamin A and Vitamin C are the two vitamins that are necessary for us since their deficiency can cause dangerous diseases, such as xerophthalmia (hardening of the cornea) and night blindness. Scurvy(bleeding gums) is caused by a vitamin C deficiency.

These two vitamins can be found in the following foods:

Carrots, cod liver oil, milk, and butter for vitamin A.

Amla, citrus fruits, and green leafy vegetables for vitamin C.
