Take Salmonella as an example. The bacterium can be killed at least 5 minutes at 70-80 C. Therefore, whether in restaurants or at home, the dishwashing water did not continue to reach the corresponding high temperature and time, the dishes and chopsticks can not play a role in disinfection.

The Second Misconception

There is no direct relationship between eating fruit and gaining weight. At the same stomach capacity, fruits provide fewer calories, whether before or after meals, fruits can prolong satiety, rich in natural micronutrients and phytochemicals, with the function of regulating intestinal microecology, but beneficial to weight control.

The Third Misconception

Vitamin C is not the more natural the better. Scientific research has found that, due to the characteristics of vitamin C, people will only stay in the body for two hours after taking vitamin C, and then will be discharged or oxidized to lose efficacy. But scientists have found an interesting phenomenon. When natural vitamin C is combined with certain minerals, it will stay in the body for up to 12 hours, or even longer, which is for the human body. Vitamin C supplementation is a tremendous boost, and I believe that these results will soon be converted into vitamin supplements for the market.

Fourth Misconception

Drinking before bed is not conducive to sleep. Drinking a small amount of alcohol before going to bed can arouse the excitement of the central nervous system, but can not sleep; even if a large amount of alcohol, the central nervous system is inhibited, resulting in drowsiness, drowsiness, but also harmful to the human body. Because the short-term hypnotic effect of alcohol for 3 to 4 hours caused by heavy drinking disappears, sleepiness will disappear, and the body will also appear symptoms of sympathetic excitement such as rapid heartbeat, shortness of breath, at which time people are prone to wake up, even insomnia.

The Fifth Misconception

High-temperature fried rapeseed will reach the smoking point of oil, not only destroy the nutritional components of oil, but also produce harmful substances such as trans fats, alkanes and benzene. Therefore, the stir-frying should not be high temperature, choose low-temperature cooking, hot pot and warm oil when stir-frying, not only retain nutrition, but also retain the fresh taste of food. Essential oil, flaxseed oil and olive oil are low saturation oils. They are more suitable for cold dressing, steaming vegetables and making soup. Peanut oil, tea seed oil and various blending oils are more suitable for stir-frying, roasting and barbecuing.

Sixth Misconception

Soy sauce is a liquid condiment brewed by fermentation of soybean and wheat. Besides water, it also contains salt, some amino acids, sugar, organic acids and other nutrients. It can be seen that soy sauce does not contain melanin, nor does it contain any photosensitive ingredients that lead to melanin production. Generally, soy sauce is reddish brown. Some of the dark soy sauces have caramel color, but this pigment will not increase the formation of melanin in the skin.

The Seventh Misconception

Ultraviolet sterilized food does not cause cancer. Because the principle of ultraviolet sterilization is to destroy DNA molecules of bacteria and viruses at a certain nanometer wavelength, so that bacteria and viruses can not reproduce. Compared with heating sterilization, ultraviolet sterilization does not destroy the nutritional composition and taste of food, nor produce carcinogens. Food sterilized by ultraviolet radiation is absolutely safe and edible.

The Eighth Misconception

Simply drinking soup doesn't have much nutrients. The study found that the nutrient content of broth is only about 1/10 of that of meat, or even lower, and the main nutrient is still in meat. Others want to use bone soup to supplement calcium. Unfortunately, this is just a beautiful fantasy. Calcium in bone is mostly in the form of hydroxyapatite, which is basically insoluble in water. Want to supplement calcium, drink milk more reliable!

The Ninth Misconception

Rice and sugar are not the same. Rice can supplement the carbohydrates needed in the daily diet, which is far less than sugar, so don't overdo it to lose weight. When dietary intake of fine grains is appropriately reduced, more nutrients can be obtained by mixing coarse grains.

Many studies have found that eating more than 600 grams (about 2.5 bags) of milk a day may increase the risk of some cancers, while eggs contain high cholesterol, and eating more than two whole eggs a day may also have potential health risks. So eat in moderation, 1 egg a day, 1 bag of milk, both nutritious and safe! uuuuuuuuuuuu

The Eleventh Misconception

Numerous studies have found that eating moderate amounts of soy food does not increase the risk of breast cancer, and women who eat less soy products have a 25% lower risk of breast cancer than those who eat less soy products. But it should be noted that soya bean milk is not soy protein powder or soybean meal. It is necessary to avoid soy milk drinks containing flavors, dextrins and sugar.
