Why do we eat?

We already know that we have to eat. Nutrients give us the materials needed for growth and the energy for life. Also, do not forget about water. It makes up about 3/4 of our body. It is used in most of the processes in the body and in the regulation of body temperature. It is also involved in many other processes.

It is important to determine the energy value of food. It tells about how much energy will be provided by eating the product. It is most often expressed in caloriescaloriecalories (cal) or in thousands of calories (kilocalories, kcal).

Both excess and shortage of food are dangerous for health. Eating too much food can lead to being overweight and even obesity. This disease destroys the body, contributes to the development of heart and circulatory system diseases, and also destroys joints and the spine.
Malnutrition is also dangerous. It results in a lack of energy for learning and playing, growth disorders and frequent diseases. Malnutrition can be the result of a serious illness called anorexia which is a mental health problem. An ill person intentionally does not eat anything to lose weight because they thinks they are obese. They usually ignore the concern of close relatives who try to make them aware that they are morbidly skinny and could damage their health.
