Micronutrients are nutrients required by organisms throughout life in small quantities to regulate a range of physiological functions. The micronutrients include iron, boron, copper, chloride, manganese, nickel, zinc, and molybdenum, while sulphur, carbon, hydrogen, oxygen, nitrogen, potassium, magnesium, calcium, and phosphorus are macronutrients.

Christopher Columbus called papaya "The fruit of the angel". The main vitamin found in Papaya is vitamin C. One medium size (200 gm) papaya contains about 226 mg vitamin C - that is two to three times more than our recommended daily dose, and it is also a good source of folate, fibre, vitamin A, magnesium, potassium, copper and pantothenic acid.

Mango, papaya, and carrot are the natural sources of vitamin A, while milk is not a natural source of vitamin A. Milk contains very small amount of vitamin A.

Heat, X-rays, heavy metal salts, etc., denature a protein, whereas infrared rays do not.

Proteins are called building blocks of our body. As per the NCERT, about 20 percent of our body weight comes from proteins. Proteins are essential for growth and repair of muscles and other body tissues. Proteins are made of amino acids that contain the elements carbon, hydrogen, oxygen, and nitrogen. We obtain proteins from animal as well as vegetable sources. Proteins of animal origin are found in milk, eggs, cheese, fish, and meat. Proteins from these sources contain all the essential amino acids (EAA) in adequate amounts. Vegetable proteins are found in pulses (legumes), cereals, beans, nuts, oilseeds, etc.

Elderly individuals are more likely to be influenced by various biological, environmental, and social factors. This would result to increase protein needs for adults as compared to younger one. Thus in practice, the protein needs of elderly people are probably higher than that for the young.
