In three years, the World Health Organization has analyzed and studied various foods involved in people's daily diet, and selected six healthiest foods, including the best vegetables, the best fruits, the best meat, the best cooking oil, the best soup and the best brain-protecting food. At the same time, fried food, pickled food, processed meat, biscuits, carbonated drinks, convenience food, canned food, preserved fruit, frozen dessert and barbecue food are also "selected" 10 junk food list.
So, what are the benefits of these healthy foods for people? Is junk food inedible at all? How should I eat? To this end, the reporter visited a number of nutritionists.
Healthy food
Vegetables shisanxian
There are 13 kinds of "the best vegetables" on the list, all of which we usually eat.
Sweet potato is the most unforgettable. Maybe you don't eat it every day, but it is rich in fiber, potassium, iron and vitamin B6, which can not only prevent aging and arteriosclerosis, but also be an anti-cancer expert, so it is chosen as the first vegetable.
Professor Zhang Jiazhi from Beijing Food Research Institute said that the daily diet pays attention to acid-base collocation, and the PH value of healthy people should reach about 7.3, while the meat we eat on weekdays is almost acidic, so we should eat it with alkaline food. Cabbage, celery and carrots in vegetables are all alkaline foods, so you can eat more.
Besides the vegetables mentioned above, you should also remember to eat more asparagus, cauliflower, eggplant, beet, shepherd's purse, kohlrabi, Flammulina velutipes, sherry red and Chinese cabbage.
Nine kinds of fruits are sweet and delicious.
When it comes to nutrition, fruits will be mentioned, but there are different opinions about the nutritional value of fruits. People really don't know what fruit to eat, but the nine authoritative fruits on the list are not credible.
The number one fruit is papaya. Although oranges and oranges rich in vitamin C are also selected, the content of vitamin C in papaya is far more than that in oranges, and papaya also helps to digest meat that is difficult to absorb in the human body and can prevent gastric ulcer.
Strawberries with sweet and juicy flesh are not only full of juice, but also beneficial to human health. Especially girls who love beauty should eat more, because strawberries can make your skin rosy and relieve diarrhea. Interestingly, strawberries can also strengthen gums, refresh breath and moisten throat. Moreover, the leaves and roots of strawberries can also be used to make tea, which is really "full".
Besides, kiwi fruit, mango, apricot, persimmon and watermelon are the best foods.
Meat dishes can be famous.
Although meat dishes are rich in fat, they are indispensable in daily diet. Therefore, eating some famous meat dishes can also give the body a balanced nutrition.
The best meat on the list is goose, duck and chicken. Professor Zhang Jiazhi said that the chemical structure of geese and ducks is very close to olive oil, which is good for the heart, especially for the elderly. Chicken is recognized as the "best source of protein", and the elderly and children should supplement it in time.
Remember to drink fresh soup after eating meat. The best quality Tang Fei chicken soup, especially hen soup, also has the function of preventing and treating colds and bronchitis, especially in winter and spring, which is better to drink now.
Bu nao Qiao chi snacks
Nowadays, many people overuse their brains. What to eat to replenish the brain is the most concerned issue for these people. No, this list has rated the best brain-protecting foods, many of which can be eaten as snacks. Come and have a try.
Spinach, leek, pumpkin, onion, cauliflower, pepper, pea, tomato, carrot, cabbage, garlic sprout, celery and other vegetables all have brain-strengthening effects. In addition, shelled snacks such as walnuts, peanuts, pistachios, cashews, pine nuts, almonds and soybeans are also good for the brain.
junk food
Three kinds of food increase the burden
The three junk foods "wanted" by the World Health Organization are fried food, preserved food and processed meat food. Think about it, these three foods will appear at almost every dinner, but too much intake will increase the burden on the body.
Convenient food is inconvenient.
Cookies, instant noodles and carbonated drinks are all convenience foods in our daily life, but convenience foods have a great influence on people's liver, so they are classified as junk food.
There are many additives in convenience foods. Professor Zhao of Shanghai Nutrition Society said that instant noodles have high salt content, and eating too much is easy to get high blood pressure and damage the kidneys. There are too many edible flavors and pigments in biscuits, and too many calories destroy vitamins, which will also increase the burden of liver function; Puffed food should not be eaten more. It has four characteristics of high sugar, high fat, high calorie and high monosodium glutamate content. Eating too much will destroy the nutritional balance, easily feel full, and affect children's normal eating.
Barbecue is as toxic as smoking.
Nowadays, barbecue is becoming more and more popular, but the food after barbecue is harmful to health. Professor Zhao analyzed that because the meat is barbecued directly at high temperature, the decomposed fat drips on the charcoal fire and then combines with protein in the meat, which will produce a carcinogen called benzopyrene. The biggest influence of this substance on human body is its strong carcinogenicity and mutagenicity.
A research center in the United States reported that eating a roast chicken leg is equivalent to smoking 60 cigarettes, and the risk of breast cancer of women who often eat barbecue is twice as high as that of women who don't like barbecue food.
Three kinds of non-staple food should not be eaten often.
In addition to the above-mentioned kinds of garbage, there are three kinds of non-staple food garbage that cannot be prevented, that is, canned food, preserved fruit and ice cream. In fact, the processed cans destroy the vitamins of fruits and fish, which will denature protein, with low nutrients and a lot of calories; There is nitrite, one of the three carcinogens in preserved fruit; Cream in ice cream and ice cream can easily lead to obesity, and high sugar content also affects dinner. If you want to lose weight, you'd better eat less.
