"Difficult to eat" fruits and vegetables healthy diet also pay attention to "good medicine bitter mouth"
Coarse grains, mouth-watering, lemon sour, garlic too red, bitter gourd too bitter ... ... the "mouthfeel" of many foods is prohibitive, but they are health foods that nutritionists respect. Is food also a good medicine? Nutritionists tell us a reason.
Astringent food. Fan Zhihong, an associate professor at the Food College of China Agricultural University, said that immature persimmons and purple grape skins are very astringent foods. Their astringency is caused by the tannins, phytic acid and oxalic acid in the food. These substances are powerful antioxidants and are good for preventing diabetes and high blood lipids. Not only that, the same fruit, astringent varieties have higher nutritional value, for example, the sour apple is better than the big and sweet Fuji apple.
Rough food. For example, coarse grains that tie the mouth, stalks of celery that are difficult to chew. This is because such foods are rich in insoluble dietary fiber. But these dietary fibers can help people prevent constipation, prevent bowel cancer, facilitate the release of metal ions, help the body detoxify, and lose weight. When you eat boiled fish, pork, and other high-fat dishes, it is the best time for rough food to work.
Bitter food. Like lemon peel, tea, dark chocolate, etc., which is rich in all kinds of terpenes, terpenoids and polyphenols, it is they make food bitter. For example, pomelo peels in lemon peel and grapefruit skin, tea polyphenols in tea, polyphenols in red wine and chocolate can prevent cancer and heart disease, and also bring a bitter taste to food.
"Chong" food. Such as radish, garlic, onions and so on. These foods are very pungent. Even after eating, there will be odors. The reason is that they contain thallium and allyl disulfide, which are all helpful in preventing cancer. For example, garlic is a human "health guard." A large number of epidemiological surveys showed that the incidence of cancer was significantly lower in garlic-producing areas and people who consumed garlic for a long time.
"Smelly" food. Durian has a strong smell. It is no exaggeration to say that it is stinking. However, in Thailand, because of its high nutritional value, it is often used as a supplement for patients and postpartum women to nourish the body. Li Huiming, professor of nutrition at the Xiangya Hospital of Central South University, said that durian fever can promote blood circulation and coldness, relieve dysmenorrhea, and is particularly suitable for women suffering from dysmenorrhea. It can also improve the cold symptoms of the abdomen and can promote the body temperature to rise. Ideal physique supplements.
"Fragrant" food. Although some foods are named after the word "sweet," the taste is very strange, such as parsley, citron, etc. The coriander contains a lot of boron, this substance can help the body absorb minerals, protect the bones, the most suitable for the elderly after the age of 40. The coriander is also rich in iron, calcium, potassium, zinc, vitamin A and vitamin C, which helps maintain blood sugar stability and prevent cancer. Studies have shown that citronella contains vitamin E and sex hormones, which have anti-aging and yang-enhancing effects. It has a certain effect on infertility. Therefore, it has the name of "progesterone".
Spicy food. The spicy taste in food is generally provided by capsaicin or volatile sulfur compounds. Capsaicin has analgesic effect, but also can increase metabolism, play the role of fat burning, weight loss. Professor Yang Li of the Chinese Academy of Chinese Medical Sciences said that mustard has a strong spicy taste and has a strong stimulatory effect. It can regulate female endocrine and enhance sexual function. It can also stimulate blood vessels to dilate, enhance facial blood flow, and make women look more ruddy. The main ingredient of mustard nose is isothiocyanate. This ingredient not only prevents tooth decay but also has certain effects on preventing cancer, preventing blood vessel plaque deposition, and assisting in the treatment of asthma.
Sour food. Shaguo, hawthorn, pickles, etc. Their sourness is brought by organic acids such as citric acid and malic acid. These natural acidic substances can promote the absorption of minerals such as iron. The same variety of fruit, the taste of the acid is generally higher in vitamin C, vitamins are more stable and easier to preserve.
In fact, these foods also have some side effects. When the intake is too large, it will hinder the absorption of protein, starch, calcium, iron, zinc, and other nutrients, so it can not eat too much.
Love sweet, fine foods, don't like bitter, rough food, can not blame people picky. Ten thousand years ago, or even just forty-five years ago, people often eat sobs. When people don't worry about diabetes, heart disease and obesity, they need to avoid malnutrition. It is not difficult to understand that the human body would naturally hate these "difficult" substances. But now, our diet is not the same as that. People worry more about how to avoid obesity and prevent cancer. So, should we also let our tastes keep pace with the times?
