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?

  1. 144
  2. 126
  3. 164
  4. 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.
