List the four basic points to be kept in mind when advising food exchange.
To develop the food exchange list points to keep in mind are:
a) Group similar foods in one group. For example cereals, roots, tubers, sugar, fat and oils are grouped under the energy giving group. Likewise milk, pulses, meat, fish, and eggs are grouped under body building groups.
b) Develop an exchange list on the basis of item si-e. For example, chapatti, idli, dosa and puris are of different si-es in different parts of India. Hence, there is need to define item si-e.
c) Calculate the energy, carbohydrate, protein and fat content of one serving.
d) Create an exchange list of different dishes in terms of item si-e that will give approximately the same amount of energy or carbohydrate or fat.Life Style Modification
