What is the importance of sugar to health and fitness?

    1. Sugar is a source of energy during exercise. Sugar is the most important and fastest energy supply substance for the body. Most of the energy during short-term and high-intensity exercise is provided by sugar; During low-intensity exercise, the human body first uses hydrogenation of sugar to provide energy, and only uses fat or protein when the sugar in the body is used up.

　　2. Sugar is the center nerve The main fuel of the system: The brain mainly relies on blood sugar to be oxidized in the brain to obtain energy to maintain normal physiological functions. Therefore, when blood sugar concentration decreases, it will affect the function of the central nervous system, cause fatigue or dizziness, and affect the effectiveness of exercise.

　　3. Sugar can save protein: under normal physiological conditions, the proportion of energy provided by protein is very low. However, if the body's sugar stores decrease, protein will be required to participate in oxidative energy supply and synthesis. Grape Sugar metabolism process. Therefore, for fitness people, taking in an appropriate amount of sugar and maintaining sufficient sugar reserves will help maintain the amount of tissue protein and balance physiological functions.

　　4. Sugar can promote physical recovery after exercise: During exercise, a large amount of sugar in the human body is consumed. Taking sugar-rich foods or sports drinks as much as possible after fitness can significantly shorten the body's recovery period and speed up the body's physical recovery.

　　5. Supplementing sugar during exercise is beneficial to stabilizing immune function: Supplementing sugar during exercise can maintain a good level of blood sugar concentration, reduce the secretion of stress hormones, and is beneficial to the stability of immune function.

　　6. Sugar can regulate fat metabolism: through sugar supplementation, the body's sugar storage and utilization can be increased. It can regulate fat metabolism, thereby inhibiting the production of ketone bodies and improving exercise capacity.
