Foods Without Calories


WHAT ARE CALORIES AND HOW ARE THEY CALCULATED?

Calories are a source of energy for the human body: therefore, they must be part of our diet, but without exceeding and overloading with caloric foods, sources of fats that are difficult to dispose of, which increase cholesterol and triglycerides, which are harmful to health.

It may therefore be necessary, in the case of particular diets or in a period of detox feeding, to also resort to foods without calories, to always be included in a balanced diet that provides our body with all the nutrition it needs.


CALCULATION OF FOOD CALORIES

To better understand what we are talking about, let's see the definition of "food calorie", which indicates the energy intake that each individual food can provide to the human body. But how are calories calculated?

Let's clarify a bit starting from the definitions:

In chemistry, the calorie is the amount of heat needed to raise the temperature of 1 liter of water from 14.5 to 15.5 degrees.

The unit of measurement that expresses the energy value of food is the kilocalorie (kcal): defined as the energy needed to raise the temperature of 1 kg of distilled water by 1 ° C.

In the international system of measurement, however, we speak of kilojoules (kj): 1 kcal corresponds to exactly 4.186 joules.

Taking these parameters into account, laboratory tests based on the combustion of water are performed, which indicate the dose of calories for each food - natural or packaged.


HOW MANY CALORIES?

The Ministry of Health has given the following provisions to guide the caloric definition of foods on food labels:

Low calorie: the product contains no more than 40 kcal / 100 g for solids or more than 20 kcal / 100 ml for liquids

Energy-reduced: the energy value is reduced by at least 30%

Calorie-free: the product contains no more than 4 kcal / 100 ml

Now that we have seen what calories are, why they are important for our body and why we must not overdo them, here is a list of calorie-free foods, and low-calorie foods that can be integrated into the diet, based on the definitions of the Ministry that we have seen above: which foods are they?
