Contrary to many people’s beliefs, many low-calorie foods have a very high nutritional value. These foods are usually fresh fruits and vegetables and contribute to a rich, healthy, and balanced diet.

Caloric and nutritional value

It is very important to distinguish caloric or energy value from what nutritional value means.

7 Foods That Contain Almost Zero Calories

When we talk about calories, we actually mean the energy value of food, and we do not take into account its potential to make us fat. The body needs a certain amount of energy or calories daily to perform various functions. Calories are not in themselves a bad thing. Their constant excess leads not only to aesthetic but also to health problems.

Nutritional value refers to the diversity and amount of macro and micronutrients. Macronutrients are carbohydrates, fats, and proteins, while micronutrients are minerals and vitamins.

Based on this, we can not conclude whether a food is nutritious or not just based on its caloric composition.

In this article, we give you 7 types of food with a caloric value below 10, and on the other hand with a particularly rich nutritional composition. This nutritious concentrated food is especially suitable during the weight loss process, but it is very important that it is always present on our daily menu.
