In 2002, the album of Time magazine in the United States introduced the top ten best nutritious foods, namely tomatoes, spinach, hard nuts, broccoli, oats, salmon, garlic, blue strawberries, green tea and red wine (in no particular order).
A survey released by the World Health Organization last year pointed out that the Japanese are the oldest group in Asia. This honor is of course attributed to the Japanese habit of advocating low-fat diet, eating more salmon and drinking more green tea. The fat of salmon is omega-3 fatty acid, which belongs to beneficial category. Tea polyphenols in green tea are phytochemicals. Both of them are equally beneficial to the body and help prevent cancer and heart disease. & gt& gt Salmon is actually very China.
Oats are rich in soluble fiber, which can effectively reduce blood cholesterol and reduce the chance of arteriosclerosis. Spinach and broccoli are dark green vegetables that can provide folic acid to help red blood cells grow normally. But also contains antioxidants, which have a protective effect and can reduce the chance of getting sick. In addition, tomatoes contain carotene (including beta carotene and lycopene), which also has anti-cancer effect and keeps you healthy.
When it comes to the advantages of hard-shell nuts, of course, unsaturated fatty acids, which are similar to omega-3 fatty acids, help to reduce total cholesterol and low-density lipoprotein cholesterol. In addition, drinking a small amount of red wine helps to reduce the risk of heart disease. Finally, garlic contains phytochemicals (allyl sulfide), which is very helpful to keep healthy. & gt& gt Another way to eat tomatoes
The above foods, each with its own characteristics, have been selected as the top ten most nutritious foods, and of course they deserve it. However, after synthesizing the above arguments, we can sum up four basic principles that food is good for health. & gt& gt The Skin-beautifying Effect of Spinach
Scientists believe that there are two great forces in the human body: one is a destructive oxidant, and a large number of oxides produced from the environment can oxidize the plasma membrane in cells and cell membranes, which not only causes damage to the body, but also is a prelude to cancer; Another strength is protective antioxidant, which plays a powerful role in antioxidation, preventing and making up for the damage caused by oxygen free radicals, preventing aging and prolonging human life. Three advantages of>& gt green tea
Antioxidants include vitamins C and E that we are familiar with and trace element selenium. Food, especially plant fruits, vegetables and cereals, contains a variety of rich antioxidants to meet the needs of the human body.
In addition to the role of phytochemicals, scientists began to study some elements called phytochemicals many years ago. These phytochemicals exist in natural foods and can prevent cancer and heart disease. Well-known phytochemicals include β carotene, lutein/flavonoids, indigo matrix, isoflavones, lycopene, tea polyphenols and allicin. Different plants contain different amounts of phytochemicals and have different functions in human body. Broccoli contains indigo matrix, which can start the enzyme system, help prevent the DNA in the nucleus from being destroyed and shrink the tumor cells. As for garlic and foreign food? Allicin can enhance immunity and increase the secretion of enzymes, thus cleaning up carcinogens.
Regarding the principle of reducing fat, lipids play an extremely important role in the human body. They can inhibit some diseases, such as preventing and controlling coronary heart disease. This effect is mainly through the subtle effects of different fat molecules. As we all know, omega-3 fatty acids can reduce low density lipoprotein cholesterol (commonly known as bad cholesterol), and can reduce the incidence of coronary heart disease for patients with high blood cholesterol and triglyceride. And fish fat also helps to improve high blood pressure. Another beneficial fat is omega-6 fatty acid, which is found in millet oil, soybean oil and sunflower seeds. By increasing the activity of bad cholesterol receptors, bad cholesterol in the circulatory system can be effectively eliminated. However, some studies have pointed out that too much omega-6 fatty acids, that is, 10% of total calories, can also reduce HDL cholesterol.
Dietary fiber With the appearance of refined food, people take less fiber from food. Dietary fiber can be divided into soluble and insoluble. The former helps to reduce the increase of blood cholesterol, while the latter stimulates the peristalsis of the large intestine and removes waste.
It can be seen that nutritious food has the advantages of antioxidants, phytochemicals, omega fatty acids or fibers. As long as you follow this method, you can naturally find alternative nutritious foods besides the top ten most nutritious foods:
1. People in China and Redmi have been handed down from generation to generation, and rice is their staple food. Generally speaking, Redmi is more nutritious than white rice, because it retains the fiber from rice husk.
2. Oranges Among many kinds of fruits, acidic fruits contain more vitamin C. Today's nutrition has unanimously praised vitamin C as one of the antioxidants:
A. prevent free radicals from damaging cells and reduce aging; B avoid sodium nitrate and sodium nitrite as preservatives from being converted into carcinogenic nitrosamines. It has a great protective effect on cancer patients, especially gastric cancer and esophageal cancer; C. inhibit the oxidation of bad cholesterol, protect cholesterol, and maintain the health of blood vessels and heart.
3. Carrots are rich in phytochemicals-β carotene, which can scavenge free radicals, prevent cell surface oxidation and abnormal changes, and play an anti-cancer role.
4. Soybeans are cheap and good quality, and isoflavones contained in them can produce similar effects to estrogen hormones, lower blood cholesterol, protect the heart and prevent breast cancer, prostate cancer and osteoporosis.
5. Fungi As we all know, fungi are rich in dietary fiber, which can enhance the ability of color plague and help fight cancer. They are recommended foods.
Generally speaking, there are thousands of kinds of food in the world, and each kind of food provides different nutrition and meets different needs, so it has its existence value. Especially in medicine, the knowledge of dietary nutrition is changing with each passing day, and we are constantly seeking new fields. Nutritional food is certainly worth recommending, and others can also be chosen. From a distance, there are more than ten kinds of nutritious foods.
