उत्तर

Deficiency of vitamin A causes Xerophthalmia (hardening of the cornea of the eye) and night blindness. So, its use is essential to us. It is available in fish liver oil, carrots, butter and milk. It promotes growth and increases resistance to diseases.

Vitamin C is very essential to us because its deficiency causes Scurvy (bleeding of gums) and pyorrhoea (loosening and bleeding of teeth). Vitamin C increases the resistance of the body towards diseases. It promotes healthy skin and allows injuries and abrasions to heal effectively. It's soluble in water. Citrus fruits include oranges, lemons, amla, tomatoes, green vegetables (cabbage), chillies, sprouting legumes, and germinated grains.
