Modern medicine believes that if you eat cold food often, it will lead to the contraction of gastrointestinal mucosa capillaries, affect the secretion of digestive substances such as gastric juice and pepsin, and naturally affect the absorption of nutrients, especially the absorption of nutrients such as protein and iron is closely related to the secretion of gastric juice.
Chinese medicine has a metaphor about the coldness of the spleen and stomach, which is very vivid: the spleen and stomach are like a pot, and the pot must be hot to cook the food in the pot. The stomach is the "pot" of the human body. If we always eat cold food, the "pot" of the stomach is always cold. How can the food in your stomach be "rotten" and the food is not cooked yet? Just like we always eat half-baked food and our bodies can't absorb it well.

Four cold foods to be careful to eat in summer:
1, cold drink
Especially in summer, many people drink a lot of cold drinks to relieve summer heat. Men drink a lot of iced beer, girls like ice cream and cold drinks, and most people have the habit of eating iced watermelons. After these cold air enters the human body, in order to resist the harm of these cold air to the human body, the human body will consume a lot of yang, so that the yang of the human body will be continuously consumed.
2. seafood
Among seafood products, except fish, shrimp and abalone, a few are warm and most are cold, such as crabs, clams and oysters. Therefore, seafood such as crabs should not be eaten. Second, when eating, you must dip in ginger juice and use the warmth of ginger juice to restrict its coldness. Some people have stomachaches when they eat crabs. The reason is that the coldness of crabs damages the stomach yang.
Step 3: fruit
Most of them are cool, such as watermelon, pear and navel orange. Many girls who lose weight often don't eat staple food, but mainly fruits and vegetables. Over time, many symptoms of yang deficiency and coldness will also appear, such as dysmenorrhea, less menstrual flow, and even late amenorrhea, because they don't eat staple foods such as whole grains and meat, but eat a lot of fruits and vegetables.
Without food and meat to supplement the yang, the yang of the human body will not be supplemented, and a large number of fruits and vegetables will continue to damage the yang of the human body, eventually resulting in yang deficiency and coldness. This cold evil will stay in the uterus, forming "palace cold" and a series of menstrual disorders. Therefore, the more fruits you eat, the healthier you will be. Also eat fruit in moderation. Do not eat on an empty stomach. It's best to eat after meals.
4. Green tea
The same is tea, black tea is warmer and green tea is colder. Green tea has the function of clearing away heat and fire. Moderate drinking can make people's throat, mouth and head refreshing and comfortable. But everything is afraid of excesses. Drinking too much green tea will reduce the body's yang, leading to insufficient yang. This way of drinking tea does more harm than good.
