Question

Give reasons.

(a) We boil milk from time to time.

(b) We should include fibrous substances in our diet.

Answer 1

(a) We boil milk from time to time in order to kill the germs and microbes present in it which can spoil the milk.

(b) We must include dietary fibres in our food due to the following reasons:

• They help to prevent constipation by increasing the volume of stool in our body. Therefore, people who include a lot of dietary fibres in their diet suffer from fewer problems of constipation.

• They help in retaining water in the body.

• They help in getting rid of undigested food easily.
