A healthy person eats the following diet - 5 g raw sugar, 4 gm albumin, 10 gm pure buffalo ghee adulterated with 2 gm vegetable ghee (hydrogenated vegetable oil) and 5 gm lignin. How many calories is he likely to get?
- 144
- 126
- 164
- 112
Correct answer: 144
Solution
Raw sugar provides carbohydrate calories, albumin provides protein calories, and both ghee types provide fat calories. Lignin is non-digestible, so it contributes no calories; summing the usable nutrients gives 144 kcal.
