Carbohydrate: role of the two sugars

More commonly known as "sugars", carbohydrates are divided into two main types: carbohydrates and sugars. In the body, they meet different needs and are not treated the same way.
 role glucides
Latest carbohydrates, more complex, are known as "sugars" because they are gradually absorbed by the intestine. They must indeed be decomposed in a first step, basic carbohydrate molecules (glucose, fructose and galactose).


They are compared to monosaccharides, known as "rapid absorption of sugars, which are immediately absorbed. These have the disadvantage of stimulating too abruptly mechanisms regulating blood sugar (insulin secretion during a meal), and not to satisfy hunger long enough.A balanced meal should contain two varieties of sugar. Unfortunately, the current trend is to replace carbohydrates and sugars (decrease in consumption of pulses and starchy foods in favor of fruit or chocolate bars).


Note finally that the absorption of fructose is also faster than other simple sugars, but it is used immediately for half and half in the reserves stored in the form of glycogen. Its use does not trigger insulin secretion, unlike other sugars "fast", which could have a definite interest in diabetes cases.
