NIOS Class 10 Home Science Activity 2.2 Solutions -Food and its Nutrients

This activity helps us calculate the daily protein requirement for ourselves and our family members based on body weight. It shows how protein is essential for growth, repair of tissues, and body health.

Chapter -1- Food and Its Nutrients Activity Solutions

 This activity has been taken from Chapter 2 – Food and its Nutrients of NIOS Class 10 Home Science (216) Module 1 – Home Science in Daily Life.

 

Aim

To calculate the daily protein requirement

Materials Required

   1. Weighing machine

   2. Pen and notebook

   3. Calculator

Procedure

We measure the body weight of each family, including us, using a weighing machine and note down the weight in kilograms.

We calculate the protein requirement using formula

Protein required per day = Body weight(kg) ×1 g

Observation

Member	Body weight (kg)	Protein requirement  (g/day)
Self	50 kg	50 g
Mother	60 kg	60 g
Father	70 kg	70 g
Brother/sister	40 kg	40 g

 

Explanation

According to guidelines, an adult needs 1 gram of protein per kilogram of body weight per day.

Protein is essential for

i.              Growth and development

ii.          Repair of damaged tissues

iii.       Formation of enzymes and hormones

iv.        Building muscles and blood

Conclusion

 This activity shows that protein requirement varies from person to person depending on body weight. A balanced diet must include sufficient protein to maintain good health and prevent protein deficiency diseases.

Frequently Asked Questions

    1.  Why is protein important in our diet?

Answer – Protein is required for body growth, repair of tissues, synthesis of enzymes and hormones, and building muscles.

   2. What is the formula for calculating protein requirement?

Answer - Protein required per day = Body weight(kg) ×1 g

   3. Can children and adults have the same protein requirement?

Answer – No, the quantity of protein depends on body weight and age. Children and adolescents need more protein for growth.

   4. What are good sources of protein?

Answer -  Milk, eggs, meat, fish, pulses, soyabean, nuts, cheese, etc.

   5. Name diseases caused by a deficiency of protein.

Answer -Kwashiorkor and marasmus
