We consume a variety of foods every day, but not everything you eat is good for your health. Some foods are eaten incorrectly; others are inherently "junk food." If readers compare their eating habits with these common dietary misconceptions, they can find out what they did wrong today? 1. The limit for daily sugar intake is 40 grams
The World Health Organization investigated the causes of death in 23 countries and concluded that the harm of sugar is worse than smoking. Nutritionists recommend a daily total sugar intake of about 30-40 grams. However, in common sweets, a tablespoon of jam contains about 15 grams of sugar, a can of cola contains about 37 grams, an ice cream cone contains about 10 grams, and a few cookies contain about 10 grams... It's easy to exceed the limit without noticing. 2. Boiled water should not be consumed after three days
Water stored for too long will be infected by bacteria and produce nitrites. Once a large amount of nitrites enters the human body, it can cause tissue hypoxia, leading to symptoms like nausea and headaches. In severe cases, it can be fatal due to lack of oxygen. Additionally, it can promote liver cancer, stomach cancer, etc. 3. The more meat you eat, the more you crave it
A recent study shows that if a person consumes high-fat foods like meat for a long time, their mouth will crave more and more, and they won't be able to stop. Excessive consumption of high-fat foods can damage brain function, impair cognitive abilities, and cause severe damage to learning and memory. 4. Improper use of MSG when cooking can produce toxins
When MSG is heated above 120°C, the sodium glutamate in it turns into pyroglutamic acid sodium, which not only loses its umami flavor but also has a certain toxicity. Adding MSG to every dish can reduce appetite. MSG should not be added before cooking dishes that are steamed, boiled, or stir-fried over high heat. Because the heating process will turn MSG into pyroglutamic acid sodium and produce toxicity, it should be added after the dish is cooked. 5. Brewing tea in a thermos increases harmful substances
It is more suitable to brew tea with water around 80°C. If tea leaves are steeped in high-temperature water in a thermos for a long time, vitamins in the tea will be completely destroyed, a large amount of tea aroma oil will evaporate, and tannins and theophylline will leach out, increasing harmful substances.

Consuming only vegetable oil can be poisonous It has been determined that peanut and corn oil can easily be mixed with the strong carcinogen aflatoxin. Cottonseed oil, if not properly processed, may contain gossypol, which can be toxic to humans. Erucic acid in rapeseed oil is not good for the health of people with high blood pressure or heart disease. Therefore, vegetable oil should not be eaten or used frequently. The correct ratio of oil should be one part vegetable oil to 0.3 parts animal oil. Drinking purified water affects the growth and development of adolescents and children
5% to 20% of the essential minerals and trace elements for the human body must be obtained from water. But purified water contains no minerals or trace elements. Therefore, long-term consumption of purified water not only fails to provide nutrition but can also dissolve and excrete some beneficial elements from the body. It is especially harmful to children and adolescents who are growing and developing. 6. The carcinogen content in potato chips is 500 times the "WHO" standard
Potatoes are not high in calories, but when made into "fries," the calories increase by 44 times. If you eat potato chips for a month, your weight will increase by 10 kg. Take a potato chip and burn it with a fire; a large amount of oil will drip out, taking about 30 seconds to burn completely, and it burns into a black mass. Eating such things can easily clog a person's blood vessels. In addition, the content of the carcinogen acrylamide in a box of french fries is 500 times the World Health Organization's standard for drinking water. 7. Drinking cola can lead to calcium loss
Children who love to drink cola beverages have an average daily calcium intake of only 60% of the human body's average requirement. In addition, the caffeine in cola increases the excretion of calcium in urine, causing acidification of the body, which is not conducive to bone development. Men who drink cola beverages can affect male reproductive ability. Once damaged sperm combines with an egg, it may lead to fetal malformation or congenital deficiency. Long-term consumption of soft drinks like cola can cause obesity, ulcers, cavities, arteriosclerosis, loss of appetite, and malnutrition. 8. Boiling dried shrimp directly for soup is not good for your health
Dried shrimp or shrimp skin can easily be contaminated with some carcinogens during processing. Drinking it directly in soup is not good for human health. Experts suggest that you can boil the dried shrimp for a few minutes, then change the water to make the soup, or add 1-2 slices of vitamin C to the soup to block the synthesis of carcinogens in the body.

A sweet-loving mite often lives in sweets like granulated sugar and powdered sugar. If the contaminated sugar is not heated, the mites will enter the human body with the food and parasitize in the gastrointestinal tract. The toxins released by the mites can stimulate the intestinal wall to have spasms, causing abdominal pain. 10. Palm oil can cause cardiovascular and cerebrovascular diseases
Because palm oil is cheap, some companies mix it into edible oil to save costs. However, long-term consumption of palm oil can lead to excessive intake of saturated fatty acids in the human body, which can cause cardiovascular and cerebrovascular diseases. If you put edible oil in the refrigerator in the summer, or if a white solid appears when the temperature is low in winter, it means the oil is mixed with palm oil. Drinking iced green tea daily can increase weight by 4-9 kg in a year Green tea has long been hailed as a healthy drink and a good way to lose weight, and is very popular. However, Liu Liyi, a registered nutritionist and Hong Kong psycho-nutrition consultant, said that a 500ml bottle of green tea contains 46 grams of sugar. This green tea has about 184 kcal. If the consumer drinks one bottle daily after consuming enough calories for the body, they can gain 4-9 kg in a year. 11. One can of beer a day can lead to gaining 7 kg in a year
If you drink only one can (375ml) of beer a day, you can intake 147 calories. After a year, your weight will increase by 7 kg. Therefore, people who are afraid of gaining weight should not drink draft beer; it's best to drink pasteurized beer or dry beer. In addition, do not drink beer before going to bed, otherwise it will cause frequent urination at night.
