2. INTRODUCTION
 Life cannot be sustained without adequate nourishment.
 Man needs adequate food for growth and development and
to lead an active and healthy life.
 Food plays an important role in maintaining a person's
nutritional and health status.

5. CLASSIFICATION OF FOOD BY ORIGIN
 PLANTS
 Many plant & plant part are eaten as a food.
 Seeds are good source of food for animals including humans
because they contain nutrients.
 All seeds are not healthy. Eg- apple seeds & cherry seeds
contains cyanide.

6. PLANTS
 Fruits are ripened ovaries of plants including seeds within it.
 Vegetables are another most natural way of getting foods.

7.  ANIMALS
 They are used as a food directly or indirectly
 Direct- Meat, fish, chicken etc.
 Indirect- milk, honey, milk products ,eggs etc.

10. CLASSIFICATION OF FOOD BY FUNCTION
 Energy Yielding Foods
 This group includes foods rich in carbohydrate, fat and
protein. They may be broadly divided into two groups
 Cereals, pulses, roots and tubers(stems): Cereals provide
in addition to energy large amounts of proteins, minerals
and vitamins in the diet. Pulses also give protein and B
vitamins besides giving energy to the body

11. Energy Yielding Foods
Fats, Oils and pure carbohydrates like
sugars: Sugars provide only energy and fats
provide concentrated source of energy.

12. CLASSIFICATION OF FOOD BY FUNCTION
Body Building Foods
 Foods rich in protein are called body building foods. They
are classified into two groups.
1) Milk, egg, meat & fish. They are rich in proteins of high
biological value. These proteins have all the essential
amino acids. (When a protein contains essential amino
acids in the right portions required by humans, we say it
has high biological value).

13. CLASSIFICATION OF FOOD BY FUNCTION
Body Building Foods
 Foods rich in protein are called body building foods. They
are classified into two groups.
2) Pulses, nuts and oilseeds: They are rich in protein but
may not contain all the essential amino acids required by
the human body.

14. CLASSIFICATION OF FOOD BY FUNCTION
 Protective Foods
 Foods rich in protein, vitamins and minerals have
regulatory functions in the body like maintaining the
heartbeat, water balance, temperature, etc.
 Protective foods are broadly classified into two groups
1) Foods rich in vitamins and minerals and proteins of high
biological value (e.g.) milk, egg, and fish.

15. CLASSIFICATION OF FOOD BY FUNCTION
 Foods rich in certain vitamins and minerals only (e.g.)
green leafy vegetables and fruits.

16. CLASSIFICATION OF FOOD BY NUTRITIVE VALUE
1) CEREALS & MILLETS (bajra in hindi)
 They provide about 70-80 % of calories, proteins & other
nutrients
2) PULSES
 Dried pulses are rich in proteins containing about 19-24%
3) NUTS & OIL SEEDS
 They contain proteins 18-40%.

17. CLASSIFICATION OF FOOD BY NUTRITIVE
VALUE
4) VEGETABLES
 They are categorized as green leafy vegetables, roots &
tubers & other vegetables
 They contain high amount of nutrients & are very healthy

18. CLASSIFICATION OF FOOD BY NUTRITIVE
VALUE
5) FRUITS
 They are rich in vitamins.
6) MILK & MILK PRODUCTS
 1 litre of cow’s milk provide about 35 g protein, 35g fat, 1 g
calcium, 1.5mg riboflavin (vit B2),1500 IU of Vit A & small
amounts of Vit B & minerals.

19. CLASSIFICATION OF FOOD BY NUTRITIVE
VALUE
7) EGGS
 Hen’s egg contains 13% of protein & 13% of fat.
 Egg white contains of 12% of protein, some vitamin &
traces of fat.
 Egg yolk contains 15% protein & 3% fat.

20. CLASSIFICATION OF FOOD BY NUTRITIVE
VALUE
8) MEAT, FISH & ANIMAL PRODUCTS
 Meat- Rich in protein 18-22%
 Fish-Rich in protein 18-22%
 Liver- Rich in protein 18-20%
