Is your diet healthy? Do you know what kind of diet is healthy? The following small series will tell you about the eating habits we used to think of. Misunderstanding 1: Food is divided into "good" and "bad". Just as people are used to dividing people into "good people" and "bad people", food is often labeled with "good food" or "bad food." Experts say that there is no absolutely bad food, only bad eating habits. The most typical example is fat. Many people think that eating too much fat increases the risk of cardiovascular and cerebrovascular diseases. However, this only has guiding significance for people with excessive fat intake, and it is not suitable for children with malnutrition in remote and poor areas. Fat also has a "good" side, and proper supplementation can promote growth and provide energy. Myth 2: Eating less staple food is healthier. In recent years, the staple food of our residents has been eaten less and less. Compared with 20 years ago, each person ate less than 2 staple foods per day. This problem also exists in the United States. American Nutrition Society spokesman Mayor Nolan Cohen said that staple food is the basis of diet, low-carbohydrate diet is not scientific, may lead to bad breath, diarrhea, fatigue and so on. Carbohydrates in staple foods are important nutrients indispensable to the human body. They are important for constituting body tissues, maintaining nerve and heart functions, enhancing endurance, and improving work efficiency. In general, adults should eat 250 grams to 400 grams of staple food a day. Misunderstanding 3: Fine rice white noodles are the most supportive. The polished white rice has a delicate taste and is really more appealing. However, in the view of Ms. Catherine Brooking, a nutrition expert in the United States, long-term consumption of polished rice is not good for health, and it is better to eat some coarse grains. Liu Qingchun said that the processing of rice noodles will lose a lot of nutrients, especially dietary fiber, B vitamins and minerals. Therefore, it is a wise choice for people to eat coarse grains (50 grams to 100 grams) every day. Myth 4: The sugar content of the fruit is too high. This issue does not need to be too worried. Fruits do contain sugar, about 5% to 10%, but also contain many nutrients, such as vitamin C, vitamin K, folic acid and other water-soluble vitamins, anthocyanins, lutein and other plant compounds, as well as a large amount of dietary fiber and Minerals. Overall, eating moderate amounts of fruit is good for your health. It is best to develop the habit of eating fruit every day, but to control the amount, 200 to 400 grams per day. Myth 5: The dinner is the most abundant. In a fast-paced life, many people often make breakfasts and lunches at will, and they eat very richly at home at night. In this regard, US nutrition expert Ms. Joey Bauer said that three meals a day are very important, can not be separated from the primary and secondary, neglecting breakfast and lunch will directly affect the working conditions during the day, too much attention to dinner will lead to obesity, affect sleep . Ma Guansheng suggested that three meals a day should be allocated reasonably. In general, breakfast should account for 25% to 30% of the total energy of the day, and lunch and dinner account for 30% to 40%. The survey shows that the quality of breakfast for Chinese people is generally not high and needs special attention. Myth 6: The food should be taken care of. Garlic onions with food and stomach, yogurt bananas to eat carcinogenic, seafood encounters vitamin C will produce arsenic ... food phase theory has been widely spread. Experts say that more than 95% of these statements are nonsense, 4% is a bit reasonable, but can not withstand scrutiny, 1% may be established but do not care. Some people say that marine pollution is serious. Seafoods contain heavy metals such as pentavalent arsenic. Vitamin C, which is rich in fruits and vegetables, will help them reduce their reactions in the body and form arsenic. But the truth is: First of all, marine pollution is not so serious, even if the marine products contain arsenic, it is also trace amounts; in addition, the human body is not like a test tube, food is not a pure substance, the degree of reaction between them is weak, not too much worry. Misunderstanding 7: The more expensive, the more nutritious. Is nutrition proportional to price? Nutrition experts do not agree. Ma Guansheng pointed out that the nutritional value of foods with high prices such as bird's nest, shark's fin and abalone is not outstanding. Taking abalone and eggs as examples, the nutritional content of the two is not much different, but the price is very different. There are still many people who prefer imported fruits and think that their nutritional value is higher, which is not the case. Domestic fruit and imported fruit are the same in terms of nutritional value. Instead, imported fruits are mixed across the ocean, and vitamin C content will be greatly reduced. Therefore, when purchasing food, don't be superstitious about the price. Local, seasonal and fresh food is better. The article is edited by http://cd.gojiaju.com Chengdu Home Network.
