Summer is coming, I have no appetite, and I feel a little nauseous when I eat. Very uncomfortable. Who can tell me what's wrong?

This is because the temperature outside is high. Every time the temperature rises 10℃, the body will reduce its demand by an average of 70 calories. In summer, the body needs less calories, so people don't feel hungry; People can't feel water evaporation in air-conditioned rooms, so their water intake is less, but the gastrointestinal tissue has been slightly dehydrated, which will also affect their appetite; It's easy to get thirsty in summer. Some people are used to drinking sugary drinks, but "sugar" is a natural appetite suppressant. Sugar can be quickly absorbed by the blood, which will make people feel full at once, so they can't eat. Over time, a vicious circle has been formed. Therefore, we should pay attention to the following "four positives" and "five supplements" in diet.

Correct four bad habits

1. Eat cold drinks or iced products after meals. Because of the heat, I often drink a cup or a bowl of iced products after meals, but a can of iced coffee is 1 15 calories, and an ice cream is 280 calories. When we drink a drink, we only feel that we are quenching our thirst, but we don't feel that we are taking in calories. But then we are in big trouble, because our body consumes 65,438+000 calories, and we have to climb the stairs for 27 minutes or walk for 65,438+0 hours. Have you ever done this? The wise choice should be to drink boiled water or mineral water. Maybe it didn't taste good at first, but I got used to it. Once you develop a light taste, you are not used to drinking sugary drinks.

2. Drink more desserts such as mung bean soup. Many people will drink mung bean soup because they can't eat it, but these foods are just like rice. If you eat too much, you will get fat. The smart thing to do is to replace, not to participate. If you want to drink a bowl of mung bean soup after dinner, remember to reduce your appetite by a quarter. If you want to eat mung bean soup as a meal, you can put some sugar, add low-fat milk and eat some fruit, which will achieve the same nutrition as dinner.

3. eat fruit. Summer is a period of abundant fruits. Most people are not alert to fruits and eat a lot. In fact, sugar in fruits can also raise blood lipids and blood sugar. The wise choice should be to eat more vegetables and less fruits.

4. Drink fresh milk as boiled water. It is hot in summer and fresh milk is nutritious. Many people will drink fresh milk as boiled water. However, it has been pointed out that high protein will hinder the absorption of calcium. The wise choice should be to follow the advice of nutritionists and only drink 2~3 cups of milk every day.

Appropriately supplement the five elements

1. Add water before meals. Drink 1 glass of water one hour before meals, which can not only relieve gastrointestinal dehydration, but also promote gastrointestinal peristalsis, gastric emptying and appetite.

2. supplement vitamin B 1. Drinking a lot of water and cold drinks in summer is easy to wash out the vitamin B family because of sweating, which leads to loss of appetite, because vitamin B 1 in the vitamin B family can convert carbohydrates in food into glucose and provide energy for the operation of the brain and nervous system. Without it, although I eat as usual, I have insufficient energy in my body and show listlessness. The most abundant source of vitamin B 1 is all cereals, such as wheat germ, soybean and brown rice. And pork is the most abundant meat.

3. Supplement vitamin B2. Vitamin B2 is responsible for converting heat energy, which can help the body release energy from protein, carbohydrates and fats. Vitamin B2 is more needed in summer when the activity is high, because the demand for vitamin B2 increases with the increase of activity. The best food sources of vitamin B2 are dairy products, such as milk and cheese, and green vegetables, such as spinach and cauliflower.

4. Supplement vitamin B3. Vitamin B3, together with vitamin B 1 and vitamin B2, is responsible for carbohydrate metabolism and provides calories. Lack of vitamin B3 can cause anxiety, anxiety and irritability, so people often feel irritable in summer. Foods rich in vitamin B3 include fish, chicken and milk. 5. Supplementing vitamin C The summer heat is actually a source of stress, which can supplement the compressive vitamin C. Vegetables and juices such as celery juice and pineapple juice made by yourself in summer can not only replenish water, but also enrich vitamin C..
