Eating radish in winter and ginger in summer keeps you healthy all year round. "This proverb tells the benefits of eating ginger in summer. Ginger is pungent, slightly warm, light and non-toxic, and it is not lacking all year round. Stir-frying with raw salt can make soup, which is also an indispensable seasoning in meals. Ginger can benefit spleen, stimulate appetite, stop vomiting, warm channels and dispel cold, relieve headache and fever, and regulate colds, cholera, abdominal pain, vomiting and diarrhea. Modern pharmacological research also believes that ginger contains volatile oil, gingerol and other components, which can promote human blood circulation, excite nervous system, help dispel wind and cold, stimulate the secretion of digestive juice in gastrointestinal tract, and strengthen the digestive function of gastrointestinal tract. According to the pharmacology of ginger and the physical characteristics of summer people, eating ginger in summer has the following advantages: 1. Stimulate appetite. Due to the hot summer, the human body is attacked by summer heat, sweating too much, and the secretion of digestive juice is reduced. People are used to being greedy for cold, like to eat raw and cold food, and feel cold at night, which is easy to produce summer heat and dampness and affect the spleen and stomach. So in summer, people have a bad appetite, eat less and are very tired. Gingerol in ginger can stimulate the taste nerve on the tongue, stimulate the receptors on the gastric mucosa, promote gastrointestinal congestion through nerve reflex, enhance gastrointestinal peristalsis, promote the secretion of digestive juice and enhance digestive function. It can also stimulate the small intestine and enhance the absorption function of intestinal mucosa, thus playing the role of appetizing, strengthening the spleen, promoting digestion and stimulating appetite. Therefore, eating ginger in summer can obviously increase people's appetite. 2. Detoxification and sterilization. In summer, people like to eat cold drinks, cold dishes, popsicles, ice cream and other cold foods. These foods are easily contaminated by external bacteria. If eaten carelessly, it will cause nausea, vomiting, abdominal pain, diarrhea and so on. The volatile oil contained in ginger has the function of sterilization and detoxification. In addition, the temperature is high in summer, so fish is not suitable for preservation and its freshness is low. If you put some ginger, it can be used for seasoning and detoxification. 3. Dispel wind and cold. In summer, people like eating cold products. If they eat too much, it is easy to cause spleen and stomach weakness, abdominal pain, diarrhea and other symptoms. Ginger has the functions of warming middle warmer, dispelling cold and relieving pain, which can avoid the above phenomenon. Ginger volatile oil can promote blood circulation, and has an exciting effect on cerebral cortex, heart, medulla oblongata respiratory center and vascular motor center. Adding some ginger to your diet can refresh your mind, dispel wind and cold, and prevent abdominal cold. However, because ginger has pharmacological effects, there are certain taboos, so we should pay attention to the following problems when eating ginger in summer: First, people with yin deficiency and excessive fire, red eyes and internal heat, or carbuncle, swelling, pneumonia, lung abscess, tuberculosis, gastric ulcer, cholecystitis, pyelonephritis, diabetes and hemorrhoids should not eat ginger for a long time. Secondly, from the point of view of treatment, ginger brown sugar water is only suitable for patients with cold or fever after rain, but not for patients with summer heat or wind-heat cold, and can not be used to treat heatstroke. Taking fresh ginger juice can cure vomiting caused by cold, but it is ineffective for other types of vomiting. Third, don't eat rotten ginger. Rotten ginger will produce a very toxic substance, which can denature and necrosis liver cells, thus inducing liver cancer, esophageal cancer and so on. The saying that "rotten ginger doesn't stink" is wrong. Fourth, eating ginger is not as much as possible. In hot summer, people are prone to dry mouth, polydipsia, sore throat and sweating. Ginger is spicy and warm, and belongs to hot food. According to the principle of "heat is cold", it is not advisable to eat more. You can put a few slices of ginger when cooking or making soup.
