What are the four foods that must not be eaten in winter? Have you noticed?

As soon as beginning of winter passed, the weather became colder and colder. Besides eating more tonic and cold-proof foods in winter, we also need to know which foods can't be eaten in cold winter. Because there are more dietary taboos in winter than in summer, if you eat wrong, you will eventually suffer. The following small series will introduce you to the foods that we should avoid in the cold winter.

Onion and garlic food. Onions, garlic and leeks contain a variety of nutrients, which are beneficial to health, such as protecting the heart, but also cause gastrointestinal discomfort, such as flatulence and abdominal cramps. But it seems that cooking can make the nutritional mixture that causes gastrointestinal discomfort have no adverse effects.

Sweet greasy food. Some people are busy eating a lot of foods high in sugar, fat and protein as soon as it gets cold. The fat in meat and protein are relatively high. Once you eat too much meat, it will lead to anorexia and gastrointestinal dysfunction. Eating too much sweets will affect human immunity. Chocolate, ice cream and other sweets are high in calories, which will increase the burden on the stomach and increase the risk of obesity.

Spicy and fried food. The weather in autumn and winter is relatively dry, and people's stomach fire is relatively strong, especially not suitable for eating spicy and fried food, otherwise it is tantamount to "adding fuel to the fire" to the fragile stomach. However, fried barbecue foods are generally oily and salty, and it is difficult to be absorbed and digested by the stomach. Studies have shown that food will produce carcinogens such as benzopyrene and nitrosamines during frying and baking. Coupled with the dry weather and lack of water in the body, these carcinogens can easily accumulate in the gastrointestinal tract, affecting intestinal health.

Acidic drinks. Acidic drinks will stimulate the esophagus to a certain extent, so that the sensory nerves are stimulated and the stimulated parts will be red and swollen. If you get up in the morning, the first thing to do is to drink a large glass of citrus juice, which will increase the acidity in the gastrointestinal tract. If you drink sweet lemonade with high fructose concentration at this time, you should pay more attention, because eating too much sugar will cause diarrhea.

Besides, what other fruits can't be eaten in winter?

1. Grape. Some unscrupulous traders and fruit farmers use ethephon as a ripening agent. After users dilute ethephon in proportion with water, they soak immature green grapes in the diluent, and the green grapes will become purple grapes in a day or two. Although this drug has low toxicity, it is harmful to human health if taken for a long time.

2. Watermelon. Excessive use of ripening agents, swelling agents and highly toxic pesticides makes watermelons toxic. The stripes on this watermelon skin are uneven, and the flesh is particularly bright after cutting, but the melon seeds are white and have a bad smell in the mouth.

3. strawberries. There are hollow, irregular and huge strawberries in the middle, which are usually caused by too many hormones. After using ripening agent or other hormone drugs, the long-term growth of strawberry becomes shorter, the color becomes fresh, but the fruit taste becomes weak. This kind of strawberry must be eaten carefully. Eating too much will affect people's normal growth and development, such as causing premature birth of children.

4. bananas. In order to make the banana peel yellow and beautiful, some unscrupulous traders ripen it with sulfur dioxide, but the pulp is still hard and not sweet at all. Sulfur dioxide and its derivatives are not only harmful to human respiratory system, but also cause brain, liver, spleen, nephropathy, and even harmful to reproductive system.
