What should I eat before swimming 1 What should I eat before swimming?

It is best to eat a little banana before swimming to avoid cramps to the greatest extent! This is suitable for swimming in the morning.

However, bananas are generally not eaten on an empty stomach. You can eat some ordinary food first and then eat some bananas in the middle, which is better.

If possible, try to control your diet, because swimmers are prone to hunger and often eat a lot, which is very unfavorable for weight control! The principle of eating before swimming is: choose a small amount of digestible high-energy food, at least before swimming 1 hour, because after eating, the whole body blood will flow to the stomach to help digestion. If you swim in the water at this time, the whole body's blood will flow to the limbs forcibly, so the blood supplied to the stomach will be less, and what you eat will not be digested well, and your stomach will be uncomfortable.

Eat less, your stomach will be comfortable and you won't be hungry when you exercise. At the same time, exercise will speed up blood circulation and stomach peristalsis, and there will be a small amount of food in your stomach, which will not cause discomfort. Before swimming 1 ~ 1.5 hours, you can drink 1 small bags of milk or sugary drinks and eat some chocolate, cheese and bread.

Cookies are also a good choice. If economic conditions permit, the energy bar with high energy and small volume is the best choice.

What are the taboos before swimming?

1, don't put bananas in the refrigerator.

As we all know, bananas are picked when they are ripe in June and July, because they ripen quickly. If they are picked when they are ripe, they taste bad and look stale. Then, after bananas are picked, the storage temperature is also high, generally 1 1- 13 degrees Celsius, while the fruits and vegetables stored in the refrigerator are generally around 4 degrees Celsius, up to 8 degrees Celsius. Bananas are easy to freeze if they are placed in this environment. If they are placed for one day, they will turn black, become soft and rot, and their taste will become worse, even appear patches or rot.

2. Immature bananas are prone to constipation.

As we all know, when bananas are immature, the skin is turquoise, and after peeling, it is hard to swallow. Mature bananas, with astringent taste swept away, are soft, waxy and sweet, and are deeply loved by children and the elderly. Bananas are tropical and subtropical fruits. In order to facilitate storage and transportation, when picking bananas, you can't wait until the skin is green. All bananas we eat in the north are ripe before they are cooked.

The astringency of raw bananas comes from the large amount of tannic acid contained in bananas. When the banana is ripe, although it can't taste astringent, tannic acid still exists. Tannic acid has a very strong astringent effect, which can form dry and hard feces, thus causing constipation. The most typical thing is that after eating bananas, the elderly and children can't help but defecate, but they can have obvious constipation.

3. Avoid eating bananas on an empty stomach

We say bananas can be used as food, but we can't eat them in large quantities on an empty stomach. Because bananas contain a lot of potassium, phosphorus and magnesium, for normal people, a large intake of potassium and magnesium will make sodium and calcium in the body out of balance, which is not conducive to health. So don't eat too many bananas on an empty stomach.

There are three taboos in fasting diet.

1, avoid high-sugar food

Because the human body can't secrete enough insulin in a short time to maintain the normal value of blood sugar, eating sugar, brown sugar, snacks, sweet potatoes and other sugary foods on an empty stomach can easily lead to a sudden increase in blood sugar.

Eating too much sugar food on an empty stomach will also destroy the acid-base balance in the body, causing stomach discomfort, heartburn, acid vomiting and other symptoms.

2, avoid irritating food.

Eating spicy, sour, salty and frozen food on an empty stomach will destroy the gastric mucosa or intestinal wall, cause gastrointestinal spasm and colic, and induce gastrointestinal diseases.

For menstruating women, eating stimulating food on an empty stomach can also cause menstrual disorder and dysmenorrhea.

3. Avoid high-protein foods.

Eating too much food with high protein content, such as milk, soybean milk, eggs and meat, on an empty stomach will "force" protein to convert it into heat energy and consume it, which will not have a nourishing effect.

In addition, in a short period of time, excessive accumulation of protein, protein decomposition process will produce a large number of harmful substances such as urea, ammonia, which is not good for health.

What should I eat before swimming? 3 Pay attention to eight taboos when swimming:

Avoid swimming before and after meals. When the blood sugar in the body is low, swimming will cause dizziness, limb fatigue and even accidents. After meals, the activity of digestive organs is enhanced, and a large amount of blood flows to the limbs when swimming, which reduces the blood volume in the digestive tract and affects the digestion and absorption of food.

Second, don't do warm-up activities. In summer, the water temperature is much lower than the temperature. Swimmers should do warm-up activities before entering the water.
