As the saying goes, there is no disease in a summer. Dog days are the hottest and most yang seasons, and they are also the most consumed period of the year. Some people suffer from the scorching heat, such as loss of appetite, excessive sweating, fatigue, irritability, chest tightness, poor sleep, loose stools, and other summer symptoms.
How to scientifically maintain health through dietary adjustment,
What about avoiding summer food safety issues?
Recently, under the guidance of the Shanghai Municipal Health Commission, the Office of the Shanghai Patriotic Health Campaign Committee and the Shanghai Health Promotion Center, at the 2024 Food Safety Week Shanghai Health Lecture Hall Event, Associate Professor Sun Lihong of Shanghai University of Traditional Chinese Medicine and Professor Liu Shaowei, Director of the Shanghai Food Safety Research Association, shared scientific dietary knowledge.
The focus is on relieving the heat and dispelling dampness and nourishing the heart
Sun Lihong introduced that there are two major characteristics of summer heat:
The first is heat, which makes the human body sweat more, consumes more energy, and is easy to consume qi and hurt, making people feel tired;
The second is dampness, which is easy to trap the spleen, causing problems in the spleen and stomach and causing loss of appetite.
Therefore, relieving heat and dampness is a major focus in summer diet and health.
Drinking water in moderation is a major focus on relieving the evil of heat and heat.
“
In summer, it is necessary to drink water in small amounts, many times, at the right time, especially after sweating, exercising and bathing. You can drink more weak tea, chrysanthemum tea, lily mung bean soup, lily white fungus soup, etc. ”
Sun Lihong introduced that sour foods such as black plum, grapes, bayberry, plums, and citrus can absorb sweat and stomach, and some sour vinegar can also be added to dishes, which can not only flavor and sterilize, but also enhance appetite.
Sun Lihong recommended
Two kinds of blood-nourishing drinks:
Lily wolfberry drink, boiled with 20 grams of lily and 10 grams of wolfberry, suitable for people with weak body, lack of qi and blood, and astringent eyes in summer;
Shengjin tea, with 10 grams of wheat and fresh reed roots, 2 pears, decoction juice instead of tea drinking, suitable for people with deficit and dry mouth.
When the human body is invaded by dampness, it can be manifested as heavy head, heavy body, sticky or sweet mouth, tooth marks and tongue, etc., and symptoms such as loss of appetite, loose stools, and abdominal distension.
“
In your daily diet, you can choose some foods that strengthen the spleen and dispel dampness, such as white lentils, barley, poria cocos, loofah, sand seeds, Huoxiang, lentils and other foods. Sun Lihong reminded, "Dampness sleeps the spleen and stomach, and while strengthening the spleen, we must awaken the spleen and appetize." The combination of color, aroma, taste, and shape in the diet can stimulate the appetite, and hawthorn, malt, chicken gold, tangerine peel, etc. have this effect. On weekdays, 9 grams of hawthorn and 6 grams of malt can be decocted with water to strengthen the spleen and appetize. ”
Traditional Chinese medicine believes that summer is fire, its sexual heat, through the heart, the main long-term nourishment, and the summer evil order. It can be seen that another key point of health preservation in summer is to nourish the mind and calm the nerves. Sun Lihong suggested that you can eat more cool and nourishing products, such as chrysanthemums, mint, honeysuckle, lotus seed hearts, etc., to relieve the heat and clear the heart. In addition, bitter foods can clear the heart and help to nourish the heart in summer, and some bitter foods can be appropriately added to the diet, such as bitter gourd, lotus leaves, asparagus, lettuce, celery, etc. However, bitter foods are often cold and should not be eaten more by people with stomach problems.
For people with upset and insomnia, you can eat some foods that clear the heart and relieve fire, calm the nerves and help you sleep, such as lotus seeds, sour jujube seeds, lilies, millet, wolfberries, etc. Sun Lihong introduced that the sour jujube kernel has the effect of nourishing the heart and liver, calming the heart and soothing the nerves, sweating and rejuvenating, and the sour jujube kernel can be ground into powder and taken one spoonful one hour before going to bed every day.
Pay attention to fruit cuts and takeaways
In addition to food therapy, special attention should be paid to food safety issues in summer to avoid diarrhea, intestinal infections and food poisoning. During the event, Liu Shaowei introduced a variety of dietary habits that may cause food safety problems according to the dietary characteristics of current residents to help everyone avoid risks.
“
When buying ingredients, choose fresh food ingredients and wash them thoroughly. Frozen foods should be thawed thoroughly before cooking to prevent the center of the food from being heated through. For the food that has not been eaten, it should be sealed with plastic wrap, and stored at room temperature, refrigerated or frozen according to the storage requirements. Before eating it next time, it is necessary to confirm whether it has deteriorated, and the spoiled food should be cleaned up in time, and the unspoiled food should be thoroughly heated and cooked before eating. Liu Shaowei reminded that raw and cooked food should be stored separately to prevent cross-contamination, and the refrigerator should also be cleaned regularly.
However, many people prefer to order takeout rather than cooking at home, eliminating the need for high temperatures. Liu Shaowei reminded that when ordering food online, it is necessary to choose a catering service unit with a valid license for online publicity, a high quantitative level of catering food safety, and a close distance, and try not to buy high-risk foods such as cold dishes, raw food varieties, and cold-processed pastries online. After receiving the food, check whether the outer packaging is affixed with the signature measures to effectively prevent the takeaway food from being contaminated during the delivery process. After inspection, it should be consumed in time and not stored for a long time.
In recent years, many fruit shops and street stalls have been favored by many consumers because of their convenience and wide variety. However, these "fruit cuts" are likely to become "dilution artifacts".
Liu Shaowei introduced:
“
Once the fruit is moldy, even if there is only one mold spot, the harmful substances in it have eroded other parts, and the whole fruit cannot be eaten. Therefore, it is necessary to beware of 'fruit cutting' and filling the number with moldy fruits. Moreover, after the fruit is cut and stored for a long time, the vitamins in it are easy to oxidize and lose, resulting in a decrease in nutrient content. If stored for too long or improperly, it is susceptible to bacterial contamination. Therefore, it is recommended that you try not to buy fruit cut boxes. ”
