Bananas are good for our health. Eating bananas before and after fitness can prevent excessive muscle consumption and promote physical recovery. According to the research data, every 100g banana contains 330mg of potassium, 0.3mg of sodium/kloc-0 and 29mg of magnesium. Potassium is an important substance involved in carbohydrate and protein metabolism in human body, which maintains normal osmotic pressure, neuromuscular stress response and normal heart function. Lack of potassium can easily make people slow down, muscle ache and limb weakness. Magnesium can maintain the excitement of muscles and nervous system, make people more sensitive, and also have the effect of eliminating fatigue.

Benefits of eating bananas after exercise:

1. Keep your body balanced

When participating in high-intensity exercise, the energy in the body needs to be continuously consumed, and people's body temperature will also rise. In order to maintain the balance of the body, the human body needs to discharge the products of tissue metabolism in time and emit excess heat, so people need to sweat a lot. In this way, the human body not only excretes a certain amount of water and salt, but also excretes a certain amount of minerals with sweat, of which potassium is a more important one. Bananas help to replenish potassium lost by sweat. At the same time, the sugar contained in banana can be quickly converted into glucose and absorbed by human body, which is a rapid energy source, and the magnesium contained in banana has the function of eliminating fatigue.

2. Help the brain to make serotonin, which can eliminate nervous system fatigue and regulate the function of hormone system.

Bananas are rich in sugar, which is an important source of tryptophan, vitamin B6 and magnesium. In addition, bananas also contain a substance called alkaloids, which can cheer people up and improve their self-confidence. Therefore, bananas have excellent effects in overcoming physical and mental fatigue.

It can prevent or treat hypertension. Because bananas are rich in potassium, they can excrete too much sodium ions and lower blood pressure. Another ion that lowers blood pressure is calcium, so if you cut bananas into small pieces and mix them with calcium-rich milk in a blender, it will become the best antihypertensive juice.

4. Improve immunity and prevent cancer. Protein in bananas can stimulate T cell differentiation, enhance the anti-cancer immunity of human body, and be directly absorbed by gastrointestinal tract, unlike other protein, so it has more anti-cancer effect.

Bananas can prevent and relieve constipation. Bananas contain a lot of fiber, which can stimulate gastrointestinal peristalsis, increase the volume of feces and help defecation.

6. Bananas contain trace element boron. Eating bananas when you are tired can quickly restore your physical strength. At the same time, banana contains 5- hydroxytryptamine, which can prevent gastric ulcer, so it can reduce the stimulation of gastric acid on gastric mucosa, and it is an ideal diet fruit for patients with gastric diseases.

Precautions:

1. Banana is cold, and people with spleen and stomach deficiency should use it with caution to avoid diarrhea and abdominal pain. At the same time, patients with renal insufficiency and diabetes should limit or even not eat bananas.

2. Sugar food is best eaten 15~30 minutes before exercise, which can provide energy for exercise.

3. When you lose weight, you can't just eat bananas, but also match other low-calorie foods to avoid nutritional imbalance.
