1、 A cup of light salt water in the morning is purely "troublemaking". Many people are accustomed to drinking a cup of light salt water in the morning, and it is recommended not to do so. Especially for elderly people with hypertension, it is not recommended. During sleep at night, people consume water and do not drink extra water. In the morning, blood viscosity is the highest, blood pressure is also unstable, and various heart accidents are prone to occur. Drinking salt water at this time may increase blood pressure, which is purely "troublemaking.". Although light salt water has antibacterial and electrolyte supplement effects, it is only suitable for gargling or drinking under special circumstances such as oral or throat inflammation, or diarrhea. The best drink in the morning is warm boiled water, with a water temperature of about 40 ℃. This temperature is close to the temperature of the human body, making it very comfortable to feel and providing better hydration. 2、 "Eating too few staple foods can make people feel" boring ". The basis for a diet is staple foods, which are the main source of carbohydrate intake. It is recommended to have staple foods for all three meals, but many people avoid staple foods. This approach is unscientific.". If there is no staple food for energy supply, on the one hand, the efficiency of brain operation will greatly decrease, resulting in dizziness, palpitations, and lack of concentration; On the other hand, staple foods are the main source of energy. Without staple foods, the human body will also start burning muscles for energy supply, causing muscle loss. Over time, people will become weak and powerless. Dietary guidelines recommend that adults should consume 250-400g of cereals, potatoes, and miscellaneous beans per day, including 50-150g of whole grains and miscellaneous beans, and 50-100g of potatoes, all of which are raw weight. 3、 Drinking Congee to "nourish the stomach" may be to "add negative" to the stomach. Drinking Congee has many benefits, but there are several points we should pay special attention to. First, you can't eat only Congee to fill your stomach. Some elderly friends are used to drinking Congee instead of normal meals, but only Congee is insufficient for energy intake. Because the rice in a bowl of Congee may be only 10-20g, most of which is water, which cannot meet the nutrition needed by the human body. Second, the main component of carbohydrate in Congee is dextrin, which increases and decreases blood sugar rapidly. Therefore, some diabetes patients, especially the elderly diabetes patients, prefer to "mix dry with thin" - first eat a little coarse grain, then drink a little Congee, and at the same time mix some protein rich food and vegetables, which is safer than simply drinking Congee. Third, Congee is not as easy to digest as people think. When eating Congee, people often do not chew it fully, so some Congee that is not cooked thick becomes a burden on the gastrointestinal tract instead of "reducing" but "adding" to the stomach. This is why some elderly people or patients with reflux esophagitis will feel uncomfortable after drinking Congee at night. If the digestion and absorption ability of the whole body is not reduced, but only the stomach is uncomfortable, you should not drink too much Congee, and don't rely on Congee to nourish your stomach. You can try to choose food that is easy to digest and absorb, and chew carefully and swallow slowly, which is more conducive to health. 4、 Preserved meat and ham are delicious but "bad". Many people like to eat processed meat products such as preserved meat and ham, and find them very delicious. However, processed meat products belong to a class of carcinogens, and the more you eat, the greater the harm to your body. Processing meat often involves processing such as pickling, smoking, and baking,
