Swimming is an excellent exercise, which can not only play a role in health care, but also play a rare role in losing weight and fat. However, there are many taboos and precautions in underwater swimming, especially in diet. Let's take a look at what not to eat before swimming and how to eat best.

First of all, never swim on an empty stomach

Swimming consumes a lot of energy, and swimming on an empty stomach is easy to cause hypoglycemia, which makes swimmers feel dizzy, weak and even faint.

Second, food should not be overheated or too cold.

The water temperature in the swimming pool is generally 27 degrees, which is about 10 degrees lower than the human body temperature. If the body gets hot because of food or drinking water before swimming, there will be a big contrast when the body enters the water, which will easily lead to vomiting or gastrointestinal discomfort. If the body is too cold due to diet before entering the water, it will increase the burden on the body in the water and affect the exercise effect.

Third, it is not advisable to eat acidic and fermented foods.

For people who don't swim often, drinking milk, yogurt or eating acidic fermented food before swimming can easily cause discomfort such as stomach acid and flatulence.

Fourth, it is not advisable to eat more chocolate.

Eating chocolate before exercise can meet the maximum energy demand during exercise, but this does not apply to swimming. Don't eat too much chocolate before swimming. Eating too much will easily cause blood to be sticky, and when the body enters the water, it will contract because the water is cold, which will easily lead to poor blood circulation.

Fifth, avoid swimming on a full stomach.

Just after dinner, the blood in my stomach is concentrated. If you go swimming at this time, the whole body blood will flow back to the limbs forcibly, and the blood supplied to the stomach will be reduced accordingly, which will easily lead to food digestion difficulties and stomach discomfort. It is not advisable to do strenuous exercise after meals, and then swim at least one hour later.

Recommended foods before swimming are: a boiled egg, a banana, or some digestive biscuits. For amateur swimmers, there is no strict requirement on the choice of food types, but try to avoid the choice of indigestible foods such as fried food and milk.

Pay attention to: 1 after swimming, and don't eat high-calorie food; 2. Add water immediately. It is recommended to eat normally after swimming 1 hour, but if swimming at night, it is best to eat a banana or light fruits and vegetables (such as cold dishes and salads, not too much seasoning and salad dressing) after swimming to prevent fat accumulation.
