Modern people pay special attention to health preservation and wellness, but many people fall into many misconceptions in this process. This is not only due to the limitations of human cognitive ability, but is also closely related to factors such as folk misinformation, media misguidance, and inducement by false advertising. Therefore, health preservation and wellness require scientific guidance. Misconception One: Eating until full is good for health
As the ancients said: "A little hunger and cold keep one safe." From a medical perspective, this is quite reasonable. Because eating to your fill every day without enough exercise can lead to excess energy, causing cardiovascular and cerebrovascular diseases. Cardiovascular and cerebrovascular diseases have become the leading cause of death for humans, posing a huge threat to human health. Modern medical research has confirmed that eating until you are 80% full is beneficial to health. It is worth emphasizing that having a rich dinner every day and eating with family every day is also a big taboo. Over time, this will cause obesity, accelerate aging, and lead to cardiovascular and cerebrovascular diseases and digestive diseases. Misconception Two: Two meals a day can help you lose weight
Some women, in pursuit of a slim figure, only eat two meals a day, thinking this will help them lose weight. On the contrary, people who eat two meals a day are more likely to gain weight. Sumo wrestlers in Japan are people who only eat two meals a day. Do you want to be as fat as them? Misconception Three: Drinking milk will increase cholesterol
The milk consumption of Chinese people is less than one-third of that in developed countries. Many people do not drink milk because they think it will increase their cholesterol. This is not the case. Research has found that the cholesterol content in milk is not high, and certain components in milk can also inhibit cholesterol. Medical research has also confirmed that drinking milk helps reduce coronary heart disease and treat high blood pressure. However, people who like to drink milk also have misconceptions. They are used to drinking milk on an empty stomach. This has many disadvantages: drinking milk on an empty stomach is not conducive to the absorption and utilization of nutrients; drinking sour milk on an empty stomach will make the acidity in the stomach too strong, making it difficult for lactic acid bacteria to survive in the gastric juice, which reduces the health benefits of sour milk. Misconception Four: Being partial to pickled foods
Pickled foods are refreshing and appetizing, so many people like to eat them. However, pickled foods contain more nitrosamines and polycyclic aromatic hydrocarbons, which are two carcinogens. Therefore, it is best to eat less pickled food. Misconception Five: Soy milk does not need to be cooked
It is very beneficial to eat some soy products every day. But soy milk must be cooked before drinking. If soy milk is not cooked thoroughly, the trypsin inhibitors it contains will not be destroyed. Not only will the soy milk be difficult to digest, but it will also cause nausea, vomiting, and diarrhea. Misconception Six: Eating fruit can clean the mouth
Some people like to eat some fruit after meals, intending to use it instead of rinsing their mouth to clean the oral cavity. In fact, fruit contains a lot of sugar. This sugar and fruit residue will ferment and turn sour in the mouth, corroding teeth and causing cavities. Therefore, after eating fruit, you still need to brush your teeth or rinse your mouth. Misconception Seven: Not daring to eat fatty meat
It is widely recognized that eating high-fat foods for a long time can easily lead to cardiovascular and cerebrovascular diseases. However, not eating any meat at all is also not good for your health. Animal fat contains a substance that can prolong life, called alpha-lipoprotein, or high-density lip protein. It not only does not promote atherosclerosis, on the contrary, it can also prevent it. Fat-soluble vitamins, such as vitamins A, B2, B6, B1, and E, and lecithin and cephalin, which are indispensable for brain development, must also be obtained by consuming fat. If children eat a low-fat diet for a long time, it will affect the development of the brain and the whole body. Misconception Eight: Old hens are the best for nourishing the body
It is a long-standing folk saying that old hens are the best for nourishing the body. The fact is: old hens of many years contain excessive chicken fat, their muscle elastic fibers are reduced, their connective tissues are aging, the meat is tough and coarse, it is difficult to cook tender, and it is not easily digested and absorbed by the stomach. A one-year-old chicken is suitable for both boiling and stewing, is easy to cook until tender and crispy, and the meat is fresh and delicious. Misconception Nine: The more fish you eat, the better
The fat in fish contains unsaturated fatty acids, which has the effect of resisting atherosclerosis, and is very beneficial for preventing and treating cardiovascular and cerebrovascular diseases, enhancing memory, protecting vision, and eliminating inflammation. But eating fish is not as much as possible. The fatty acids in fish can effectively inhibit the aggregation of platelets. Long-term excessive consumption of fish can reduce platelet aggregation and cause various spontaneous bleeding, such as subcutaneous purpura and cerebral hemorrhage. The Eskimos mainly eat fish. It was found that although almost none of them suffer from coronary heart disease or cerebral thrombosis, cerebral hemorrhage has become an important cause of their death. Misconception Ten: Brewing tea with boiling water
Brewing tea with boiling water will destroy many nutrients in the tea leaves and will also dissolve too much tannic acid and aromatic substances, making the tea bitter and astringent and reducing its nourishing and health-preserving effects. The water temperature for brewing tea should generally be around 80°C, and it can be slightly higher in winter. Misconception Eleven: Eating more vinegar is good for you
Vinegar can increase appetite, whet the appetite, protect vitamin C in vegetables, and promote the absorption of vitamin C by the gastrointestinal tract. It also has a certain effect in lowering blood pressure and preventing influenza. Therefore, some people think that eating vinegar has many benefits and consume it excessively. Some people even drink vinegar directly. However, excessive consumption of vinegar can burn the esophagus, corrode the mucosa, damage the spleen and stomach, soften the bones, aggravate osteoporosis, and lead to fractures. Misconception Twelve: Chewing gum can strengthen teeth
Some advertisements say that chewing gum can strengthen teeth, so many people eat chewing gum without rinsing their mouths. In this way, the sugar in the chewing gum will also ferment and produce acid in the mouth, corroding teeth and causing cavities. In addition, chewing gum contains additives such as vulcanization accelerators and anti-aging agents, which are all toxic. The metabolic products of plasticizers in chewing gum are more toxic. After being absorbed into the blood through the digestive tract, they can harm human health.
