A healthy person eats the following diet – 5 gm raw sugar, 4 gm albumin, 10 gm pure buffalo ghee adultrated with 2 gm vegetable ghee (hydrogenated vegetable oil) and 5 gm lignin. How many calories he is likely to get?

Options

(a) 144
(b) 126
(c) 164
(d) 112

Correct Answer:

144

Explanation:

Physiological value of carbohydrates is 4.0 kcal/g, proteins 4.0 kcal/g and of fats is 9.0 kcal/g. Hence
5 g raw sugar will yield
5 x 4.0 = 20.0 kcal
4 g albumin (protein) will yield
4 x 4.0 = 16.0 kcal
10 + 2 g of fat will yield
12 x 9.0 = 108.0 kcal
Total yield = 144 kcal
