It is the first data that we usually observe in the labeling of the foods we consume and for many, it is of great importance if we seek to obtain how much energy we consume every day. So, we ask ourselves, how are calories calculated from food?
Kilocalories and non-calories
Although we are accustomed to talk about calories, the truth is that we should always always name the kilocalories that are what we actually consume and spend.
In food labeling we can see your energy intake indicated in kilocalories per 100 grams or per serving and a kilocalorie (1000 calories) represents the thermal energy needed to increase the temperature of one gram of water by one degree centigrade to a normal pressure Of an atmosphere.
Thus, foods indicate the amount of energy they offer in terms of kilocalories and our body burns in equal energy.
