How to bring your own lunch without hurting your stomach

Nowadays, many office workers have the habit of bringing meals at noon. Most of them put their food in the refrigerator the night before and take it to work the next day. According to the statement that "the risk of stomach cancer is 3.6 times higher after eating overnight vegetables", the nitrate in overnight vegetables will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating. The damage and destruction of gastric mucosa may lead to gastric ulcer, atrophic gastritis and even gastric cancer.

At present, clinical observation shows that the etiology of gastric cancer is the result of long-term interaction of many factors, which is related to living habits, diet types, environmental factors, genetic factors and mental factors, as well as gastric polyps, gastric mucosal dysplasia, postoperative gastric stump cancer and long-term Helicobacter pylori infection. A single risk factor is not enough to induce cancer.

Eat less overnight meals, but it is not impossible.

If food is stored at 0-4 degrees Celsius for less than 20 hours, it is unlikely to go bad. Eating such a luncheon is unlikely to cause stomach trouble. Just like when we travel by plane, radiation is inevitable, but it is not enough to cause disease.

Eat less overnight meals, but it is not absolutely impossible. Researchers from the Food Inspection Institute of the Institute of Product Quality Inspection of Fujian Provincial Quality Supervision Bureau inspected vegetables, braised pork, braised fish and rice stored in fresh-keeping boxes for half an hour, 4 hours, 9 hours and 24 hours respectively. The results showed that the nitrite content in these diets was less than 65438 0 mg/kg. The nitrite content of meat stored at room temperature for 4 hours is also lower than 1 mg/kg. The national regulations on nitrite content are: 4 mg/kg, 3 mg/kg of fresh meat and 3 mg/kg of rice.

From the point of view, overnight dishes, especially overnight dishes, are not only low in nutritional value, but also easy to deteriorate. They all contain nitrate, and the contents from high to low are: petiole, leaf, stem, root, flower, potato, bulb, fruit and seed. In other words, the nitrate content of beans, cucumbers, tomatoes and onions is very low, while the nitrate content of spinach, leeks, celery and other vegetables is relatively high and easy to deteriorate. After contaminated overnight meals, bacteria will multiply in large numbers, causing gastrointestinal and even food poisoning.

With the accelerated pace of life, many people have some stomach problems, such as common atrophic gastritis. Some patients worry that atrophic gastritis will become cancerous. In fact, only 1% patients may turn into gastric cancer, and autoimmune atrophic gastritis is more likely to develop into gastric cancer. Early gastric cancer is mostly asymptomatic or has only mild symptoms, such as epigastric pain, loss of appetite, bloating, acid reflux and sudden weight loss. When the clinical symptoms are obvious, the lesion is already in the advanced stage. Therefore, if you want to find the disease early, you must insist on regular physical examination. Especially for people over 40 years old, it is one of the effective preventive methods to go to the regular physical examination center every year.

Healthy lunch rule

1. You'd better cook now in the morning. The preservation time of leftovers should be shortened to 5 to 6 hours as far as possible, and they should be thoroughly heated before eating. Leftover rice can easily cause food poisoning, but most of the leftovers look the same, which makes people careless.

2. After cooking, cool naturally, then cover the lunch box and put it in the refrigerator. However, seafood, green leafy vegetables and cold dishes are easy to deteriorate overnight, so it is best not to eat them the next day.

3, open the food, otherwise it is easy to breed bacteria.

4. Promote the use of glassware to reduce chemical reactions.

5. The vegetables to be brought should be fried for six or seven minutes when cooking, so as to prevent further damage to their nutrients when they are heated by microwave the next day.

How to eat lunch in summer is not easy to hurt your stomach?

Summer lunch should enjoy different delicacies according to physique. People with yang deficiency often cook some soup, while those with yin deficiency drink some fruit yogurt. As for fruits, doctors suggest that people with yang deficiency can bring more tropical fruits, including mangoes, pineapples, raisins, lychees, loquats, durians, etc., which are beneficial to invigorating qi and blood and activating meridians.

In summer, it would be nice to eat less lunch.

As the temperature rises gradually, many people lose their appetite. According to the doctor, Chinese medicine believes that long summer governs the spleen and soil, and damp heat is in season. Because of sweating, physical exertion naturally increases; Moreover, many people like to eat cold drinks at this time. People with spleen-stomach deficiency and cold constitution are prone to spleen-stomach disharmony, abnormal transport, fatigue and loss of appetite.

Yang deficiency often makes some soup.

Generally, people with yang deficiency are fatter, afraid of cold in winter, afraid of heat in summer and sweating more. Therefore, even in summer, they should drink more hot soup and porridge, such as mushroom soup, chicken soup, sparerib soup and fish soup. Can be salty, so as not to hurt their stomachs. Eat less cold and greasy food to avoid hurting the spleen and stomach.

In terms of fruits, doctors suggest that people with yang deficiency can eat more tropical fruits, including mangoes, pineapples, raisins, lychees, loquats, durians, etc. These fruits are beneficial to invigorating qi and blood and activating meridians. For cold fruits, such as pears, eat less or not.

Partial yin deficiency and multiple tonic

If the body is thin and usually eats less, it may be yin deficiency. The doctor said that people with yin deficiency need to eat more nourishing things. Traditional Chinese medicine believes that the foods that nourish yin meridians include beef, mutton and seafood. In addition, pasta also has the function of nourishing true yin.

People with yin deficiency should eat less fruits that get angry, that is, tropical products mentioned above, but should eat more tomatoes, watermelons, cucumbers, leafy vegetables, etc., in order to achieve the balance of the human body.

Four main points with rice

1, the overnight soup is exquisite.

Many people like to cook soup, and cook it in the refrigerator before drinking it the next day. Is this overnight soup good for your health?

Healthy diet: The best way to preserve the soup base is not to put seasonings such as salt. After the soup is cooked, scoop out what you want to drink that day with a clean spoon, and it is best to store it in the refrigerator with a clay pot. Because the leftover soup is stored in aluminum pot and stainless steel pot for a long time, it is prone to chemical reaction, so it should be kept in glass or ceramic utensils.

2, leafy vegetables should not be eaten overnight.

It is said that the low incidence of gastric cancer is related to the habit of not eating overnight dishes. Because some green leafy vegetables contain more nitrate, if they are left for too long after cooking, nitrate will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating.

Healthy diet: Generally, the nitrate content of stem and leaf vegetables is the highest, while that of melon vegetables is slightly lower, with roots and cauliflower in the middle. Therefore, if you buy different kinds of vegetables at the same time, you should eat stems and leaves first, such as Chinese cabbage and spinach. If you are going to cook more vegetables and eat them hot the next day, try to make fewer stem and leaf vegetables and choose melons.

3. There should be a choice.

Lunch should be full of energy, food containing protein, vitamins and minerals.

Among vegetables, towel gourd and lotus root contain more cellulose. In addition, you can also choose celery, mushrooms, radishes and so on. When cooking, just fry the vegetables for six or seven minutes to prevent further damage to their nutrients when microwave heating the next day. Try to choose meat dishes with less fat, such as beef and chicken. After cooking, cover it immediately after cooling and store it in the refrigerator at 4℃. Take it to the office the next day and put it in the refrigerator immediately. At lunch, fully heat it in the microwave oven and eat it.

Overnight foods that are not suitable for eating include fish, seafood, green leafy vegetables and cold salad.

Fish and seafood can easily produce protein degradation products overnight, which will damage liver and kidney function. Green leafy vegetables contain different amounts of nitrate. If it is overcooked or left for too long, not only will vegetables turn yellow and taste bad, but nitrate will also be reduced to toxic nitrite by bacteria, which will cause cancer. Cold salad is polluted when it is processed. Even if it is refrigerated, it may have gone bad after a night, so it should be cooked and eaten now.

Healthy diet: you can bring your own rice, beef, bean products, all kinds of non-green vegetables, fruits, yogurt and other foods.

4. Pay attention to cooking methods.

In addition, the nutritionist reminds you that you must pay attention to cooking methods. Cooking methods suitable for microwave heating include steaming, stewing and stewing. The dishes made by these methods are not easy to change flavor and color after microwave heating, while fried and stir-fried dishes are obviously not suitable for microwave heating. In addition, compared with green vegetables, eggplant vegetables are not easy to deteriorate, and it is not easy to change the color and fragrance of dishes after microwave heating. What needs to be reminded is that the vegetables to be brought should be fried until they are half-cooked to prevent further damage to their nutrients when heated by microwave. Classic dishes, such as scrambled eggs with tomatoes and roasted eggplant, are more suitable for "people with rice".

Tips:

Be sure to choose a lunch box suitable for microwave heating.

Such a lunch box will be marked with the words "microwave oven is suitable". In addition, when heating, in order to prevent excessive evaporation of water, cover it for heating. Under normal circumstances, the time to heat the box lunch in the microwave oven is controlled at about two minutes. If the food is not hot enough, put it in the microwave oven and turn it a little.

You can also eat healthily.

Meat, fish and seafood.

Cui Jun, a nutritionist in charge of the Nutrition Department of Nortel General Hospital, reminded that rice is the best staple food with rice, and steamed bread, pies and other staple foods should not be brought into the box lunch.

Try to choose beef, mutton and chicken with less unsaturated fatty acids as meat. Pork is relatively rich in unsaturated fatty acids, so it is not suitable to be included in the box lunch category. Fish and seafood are also best not to choose. On the one hand, fish and seafood can easily produce protein degradation products overnight, which will damage liver and kidney functions. On the other hand, it is difficult for fish and seafood heated by microwave oven to maintain their original color and flavor, which will also affect their appetite from the outside.

In addition, nutritionist Cui Jun reminds you that you must pay attention to cooking methods. Cooking methods suitable for microwave heating include steaming, stewing and stewing. The dishes made by these methods are not easy to change flavor and color after microwave heating, while the fried and fried dishes are obviously not suitable for microwave heating.

Vegetables should choose eggplant.

Du, director of the Nutrition Department of Shandong Qianfoshan Hospital, reminded those who bring meals: If you want to bring meals, you'd better get up in the morning and do it well. Food storage time shall not exceed 12 hours. If it is the dish of the night before, you can seal and refrigerate the food you want to bring.

It is even more inappropriate to bring your own lunch with green leafy vegetables. Green leafy vegetables contain different amounts of nitrate, which will be reduced to toxic nitrite by bacteria when heated or stored in microwave oven for a long time, which has carcinogenic effect. Cold salad is polluted during processing. Even if it is refrigerated, it is likely to deteriorate overnight. It is not appropriate to put cold salad in a lunch box for the night. Compared with green vegetables, eggplant vegetables are not easy to deteriorate, and it is not easy to change the color and fragrance of dishes after microwave heating. What needs to be reminded is that the vegetables to be brought should be fried until they are half-cooked to prevent further damage to their nutrients when heated by microwave. Scrambled eggs with tomatoes, roasted eggplant, Chinese cabbage, soybeans, Chinese cabbage, bacon, bacon, tender kidney beans, radishes, sweet potatoes, etc. They are all suitable for "rice family".
