The brain is almost exclusively dependent on glucose, the only carbohydrate that passes from the blood to our brain. Our neurons continually need it, just like oxygen. Indeed, the glucose reserves of the brain would not exceed ten minutes!
To know: It is estimated that an adult brain consumes about 140 g of glucose per day, which is up to half of the total amount of food carbohydrates ingested.
And the more intense the mental activity, the more important our glucose needs will be.
The same goes for physical activity : our body stores energy from carbohydrates in the form of glycogen (a rapidly available glucose-based energy source) in the liver and muscles, but this is limited. The depletion of these resources is the main cause of fatigue that can occur during long-term physical activity.
This explains why it is therefore recommended to drink, and consume foods rich in glucose: dried fruits, bananas, sugar ...

Sugar and obesity
Several epidemiological studies have revealed an inverse relationship between sucrose intake and body mass index (BMI), as well as between sucrose intake and total fat (or lipid) intake.
BMI: Calculate your ideal weight!
Find out if you are overweight, underweight or of normal body build by calculating your BMI! 3 simple clicks are enough ... I calculate my ideal weight!
Thus, people who consume a large portion of their energy needs in the form of sugar are generally less overweight than those who consume a small percentage. Especially since heavy consumers of sugar often tend to eat less fat.
Nevertheless, we must not forget that overconsumption of sugar can eventually lead to weight gain. And in general, nutritionists recommend that low glycemic index sugars (legumes, apricots, whole rice) be preferred to high glycemic index sugars (such as a sugar cube).
And if we sucked otherwise?
Complete cane sugar, coconut blossom sugar, agave syrup. What if we replace refined sugars with lower glycemic index natural sugars?
