Chemistry

Why is one food more caloric than another?


Foods contain energy values.

See the following table for some energetic values. They are usually found in calories (lime) or kilocalories (Kcal).

FOOD

ENERGY VALUE (Cal / g)

Rice

3,60

Sugar

4,00

Potato

0,90

Beef

2,90

Chocolate

4,67

butter

7,60

Fish

0,84

These "energy values" correspond to the energy released in the chemical reactions of the metabolism of these foods in the body.

If we say that chocolate has a lot of calories, we really mean that in the reactions of chocolate metabolism in the body, there is a lot of energy release.
