Sugar is good for improving sports ability, so we blindly eat a lot of sugar food or food, hoping to improve sports ability and performance by supplementing sugar in large quantities. But it's useless, and it may have side effects.

Improper supplementation of sugary foods may lead to the following problems:

First, if a large amount of sugar is ingested in a short period of time, sugar will enter the blood and make blood sugar (blood sugar food) too high, because the osmotic effect of sugar makes water enter the cavity from the stomach wall and dilute it, which in turn affects the emptying of the stomach, and then causes abdominal discomfort, dizziness, nausea and other uncomfortable feelings.

However, too much sugar intake will increase blood viscosity and circulation, affect heart function and make muscles stiff, which is extremely unfavorable to fitness and exercise.

Third, eating too much sugar will increase triglycerides in the blood, which will lead to cardiovascular diseases.

In addition, eating too much sugar will affect the absorption of calcium (calcium-containing food) and relatively reduce the intake of other nutrients, thus causing malnutrition.

Finally, too much sugar can easily lead to obesity, because too much sugar will be converted into fat in the body.

The correct way:

In general training, bodybuilders or athletes don't necessarily need sugar supplements. Starch in staple food is enough three times a day, but in endurance sports (long-distance running, marathon, etc. ), due to the large consumption of sugar, in order to accelerate the disappearance of fatigue, a proper amount of extra sugar is needed.

Sugar supplement: two kilograms of sugar weighing no more than four grams, and one gram of sugar per kilogram of body weight is the right amount. If possible, it is best to use it in small quantities for many times.
