Answer:
The calories Anna consumed for dinner is 315 kcal (300kcal). The calories that came from proteins is 108 kcal (100kcal).
Explanation:
Macronutrients are nutrients such as protein, carbohydrates, and fat that provide the energy required for the normal functioning of the body. Usually, the energy obtained from macronutrients is expressed in calories. Each gram of protein provides 4 kilocalories while each gram of fat provides 9 kilocalories. Carbohydrates per gram also provide 4 kilocalories.
Here, Anna consumed 7 grams of fat (in salmon)
, 36 grams of carbohydrates (in sweet potatoes and asparagus) and 27 grams of protein (in salmon, sweet potatoes, and asparagus) for the dinner.
Therefore, total calories in 7 grams of fat is kilocalories.
Total calories in 36 grams of carbohydrates is kilocalories.
Total calories in 27 grams of protein is kilocalories.
Therefore, the total calories Anna consumed for dinner is kilocalories i.e.,
kcal.
The calories that came from proteins is calories i.e.,
kcal.
