NIOS Class 10 Home Science Activity 2.3 Solutions -Food and its Nutrients

This activity helps us calculate each family member's average daily fat intake using monthly oil and ghee consumption.

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 average daily fat consumption per family member

Material Required

   1. Oil and ghee (grocery record)

   2. Measuring jar or bottle label

   3. Calculator

   4. Pen and notebook

Procedure

We find out the total monthly consumption of oil and ghee in our family (in kg or litres). We convert oil or ghee from litres to grams using the formula: 1 litre =910 grams.

We add oil and ghee consumption to get total fat consumption per month and divide the total monthly fat consumption by the number of family members.

Now we divide the result by 30 to get the daily fat consumption per person and compare it with the recommended fat intake.

Observation

Total monthly consumption of oil per month = 3 litres

3 ×910g = 2730g

Total consumption of ghee per month= 1 kg

1kg= 1000 g

Number of family members = 4

Total fat consumption per member per month

3730g g ÷ 4 = 932.5g

Total fat consumption per member per day

932.5 g ÷ 30= 31 g/day

The average daily fat intake per family member is approximately 31 g/day, which is close to the recommended intake of 30 g per day. Therefore, the fat consumption is adequate.

Explanation

Fat is a concentrated source of energy and is essential for:

i.      Providing energy

ii.  Keeping the body warm

iii. Helping absorption of vitamin A, D, E, and K.iv.        Protecting vital organs

But excessive fat intake can lead to obesity, and too little fat can cause weakness.

Conclusion

This activity shows that fat intake should be monitored carefully. A daily intake of around 30 g per person per day for good health.
