Traditional Chinese medicine, which has been passed down for thousands of years, still has such misunderstandings

As we all know, to nourish the kidneys, we should eat more black foods, such as black beans, black sesame seeds, black-bone chicken, etc. However, the editor believes that this is a misunderstanding in health preservation. Not all black foods can nourish the kidneys. Let’s take a look at why this is the case.

Two Misunderstandings about Health Preservation in Traditional Chinese Medicine

1. Do black foods necessarily nourish the kidneys?

We often see such propaganda that "black foods nourish the kidneys and replenish blood", such as black sesame, black beans, black rice, black fungus, kelp, seaweed, black-bone chicken, etc. In fact, this is not entirely true. Warmth is tonic and cold is purgative.

Black rice and black-bone chicken are warm in nature, and have obvious effects in nourishing blood and kidney; black sesame is neutral in nature, and can nourish the kidney and liver, moisten the intestines, and nourish the hair; black beans are neutral in nature, and can nourish the kidney, promote blood circulation, and detoxify; while black fungus is cool in nature, and kelp and seaweed are cold in nature, so they can be eaten frequently in summer, but try not to eat them in winter.

Whether any food is nourishing or not depends on the properties of the food. Foods with neutral or warm properties are beneficial to the body all year round. Foods with cool or cold properties should be avoided as much as possible except in summer. If you have to eat them, they should be paired with warm ginger, chili, pepper, and Sichuan pepper. This way you can take in the nutrients unique to these foods without damaging your kidneys or stomach.

2. Does red dates tea definitely replenish blood?

Red dates, longans, peanuts, red beans, brown sugar, ginkgo nuts, and wolfberries are all foods that people often eat to replenish blood and nourish the kidneys. Among them, red dates tea is a blood-replenishing tea for many female friends, but does red dates tea definitely replenish blood?

Red dates can be fried in an iron pan until they turn black and then soaked in water to drink, which can treat stomach cold and stomach pain. If longan is added, it will become a tea that replenishes blood and qi. It is especially suitable for people who use their voice frequently, such as teachers and salespeople. If you add 4 to 6 wolfberries, it can also treat constipation. Female friends who often drink red dates, longan and wolfberry tea have fair skin and good beauty effects.

However, it is useless to make tea with red dates that have not been fried hard and black in an iron pan, because the skin wraps the dates and the nutrients cannot come out. But for the fried red dates, the skin will crack when soaked in boiling water, and the nutrients inside will slowly seep out.

There are still these misunderstandings in daily health care

1. Brush your teeth after meals

Having a set of white and neat teeth is not only the basis of physical health, but also makes people full of confidence in social situations. Some people advocate brushing your teeth after meals, but the latest research by dental experts has found that brushing your teeth immediately after meals is detrimental to dental health.

Because there is a layer of enamel on the surface of the crown. After eating, especially after eating acidic foods, the enamel will become soft. If you brush your teeth immediately, it is easy to damage it. Over time, the enamel of the teeth will gradually decrease, making it easy to develop dentin hypersensitivity, which will cause symptoms of soreness and pain when chewing. Therefore, dental experts remind you that it is best to rinse your mouth with clean water after eating and then brush your teeth after 1-2 hours.

2. Drinking eight glasses of water can ensure health

The amount of water each person needs is different. Drinking too much is not only unhealthy, but also puts a burden on the kidneys. In addition to being excreted through sweating or breathing, the water taken in by the human body still needs to be metabolized through the kidneys. If you drink too much water, the kidneys will increase their water discharge, which will increase the burden on the kidneys and easily cause kidney failure, which will easily affect the health of the kidneys. In addition, the electrolytes in the body will be diluted by too much water, causing the risk of electrolyte imbalance.

Many people only pay attention to the amount of water they drink, but ignore the fact that they also consume water in their daily diet. For example, the food, fruits, and drinks eaten at each meal contain water, and the three meals account for at least 500 ml; therefore, the amount of water you drink every day must be less than 1600 to 1950 ml, otherwise you will drink too much water. Patients with kidney disease or heart disease even need to limit water to avoid endangering their lives.

3. Sleeping naked is healthier

Sleeping naked is just for comfort and has nothing to do with health. Although wearing clothes to sleep will affect perspiration and skin heat dissipation, human body dandruff is peeling all day long, and dandruff is the nutrition source of dust mites and mold. There must be some microorganisms on the sheets and beds. If you lie naked on the bed, these microorganisms are more likely to come into contact with the skin. Sleeping naked may increase the risk of infection.
