A healthy person eats the following diet, 5 gm sugar, 10 gm albumin, 10 gm ghee, 20 gm bread, 15 gm salad and 4 litres of water. How many calories is he likely to get?
Calories
Step 1- Given data
The amount of macronutrients in the diet is given in the table below-
Food | Macronutrient | Amount |
Sugar | Carbohydrates | 5 g |
Albumin | Proteins | 10 g |
Ghee | Fats | 10 g |
Bread | Carbohydrates | 20 g |
Salad | Carbohydrates/ proteins | 15 g |
Water | - | 4 litres |
Step 2- Applying the formula
Calories obtained from various macronutrients are given as follows-
Step 3- Solving equations
Using simple multiplication, the energy from macronutrients in each type of food can be calculated as follows-
Energy from sugar= 5 x 4 Kcal = 20 Kcal
Energy from albumin= 10 x 4 Kcal = 40 Kcal
Energy from ghee= 10 x 9 Kcal = 90 Kcal
Energy from bread= 20 x 4 Kcal = 80 Kcal
Energy from salad= 15 x 4 Kcal = 60 Kcal (assumption- salad is made from proteins or carbohydrates)
Energy from water= 0
Total energy = 290 Kcal (addition of all above values).
Final answer
The healthy person will receive 290 Kcal by consuming the above diet.
