WHAT IT BRING US

The main function of sugar is to sweeten. We innately find a sweet taste pleasant and we appreciate it depending on how sweet a tooth we have. In very different cultures, a sweet taste is associated with trust and pleasure (and a bitter taste with rejection and punishment). The fact is that sugar affects the mood: for example, it is involved in the secretion of serotonin, a neurotransmitter linked to pleasure and biorhythms. It is therefore not surprising if we want sweet foods when we feel sad. There are, however, other sources of sweetness, some of them not recommended. We should discover the different sources of sweetness.

Nutritionally, sugar largely has calories, that is, energy. The sugar molecules are formed by only two saccharides (simple sugars), which is why they are digested more quickly than other carbohydrates, like cereals, which contain longer saccharide chains. That is why their energy takes less time to reach the cells, which is why, when we make a brief, intense physical effort we recover quicker with sugar (or fruit, juices, chocolate, etc.) than by eating a sandwich or a dish of pasta. Brown sugar has a few other nutrients. We should find out the nutritional differences between white and brown sugar.

Sugar is also used as a preservative, for example to make jams or syrups, because many microbes cannot survive in a sweet environment. The food industry also uses it for various purposes.
