Vegetables are essential to our daily table, but excessive consumption of vegetables is also harmful. You can't eat more of these vegetables!
First, eat too many carrots. Although carotene is very nutritious to people, we should also pay attention to eating it in moderation. Excessive drinking of vegetable juice made of carrots or tomatoes can cause carrot anemia, turn the skin of face and hands orange, and cause loss of appetite, unstable mental state, fidgeting, and even restless sleep, accompanied by night terrors, crying, talking in dreams and other manifestations.
Second, eat more spinach, which contains a lot of oxalic acid, and should not be eaten more. Oxalic acid will react with calcium and zinc in human body to produce calcium oxalate and zinc oxalate, which are not easy to be absorbed and excreted, affecting the absorption of calcium and zinc in intestine, easily causing calcium deficiency and zinc deficiency, leading to bone and tooth dysplasia, and also affecting intellectual development. Besides spinach, amaranth, water spinach, bamboo shoots, onions and water bamboo are rich in calcium, but they also contain high oxalic acid, which is easy to form calcium oxalate precipitation and affect the absorption of calcium.
Third, excessive consumption of rootless bean sprouts At present, rootless bean sprouts on the market are mostly produced by hormones and fertilizers. Under the action of intestinal bacteria, such nitrogen-containing compounds will be converted into nitrosamines, which can cause people to suffer from gastric cancer, liver cancer, esophageal cancer and rectal cancer.
These fruits are more nutritious when heated!
Many people have eaten fruit, but most people eat it raw. Do you know that some fruits are more nutritious when cooked than when eaten raw? Do you know which are fruits?
1. grapefruit is not pulp, but peel. Pomelo peel contains flavonoids such as naringin and rutin, which has antioxidant effect, can reduce blood viscosity, lose weight and resist aging. When it enters the body after heating, it will be more active and exert its greatest effect. Slice the soft white part in the middle of pomelo peel, boil it in warm water for 10 minutes, and then make tea with honey, and the nutrients in it will begin to play a role in the body.
2. The content of lycopene will increase rapidly after heating, thus improving the nutritional value of tomato and enhancing its overall antioxidant capacity. The contents of lycopene and antioxidant can be increased by 54% and 28% respectively as long as they are heated for two minutes (boiling in water or microwave).
3. Orange peel contains narcotine and orange peel oil, which has antitussive and expectorant effects. These two ingredients will only come out of the orange peel after cooking. Especially suitable for children with chronic cough. The steaming method is: wash the orange without peeling, cut a knife at the top of the orange, sprinkle a little salt on the exposed pulp, poke holes in the pulp with chopsticks to let the salt penetrate into the pulp, then cover the cut orange again, fix it with a toothpick, put it in a bowl, put it in a steamer without adding water, and steam for 15 minutes after the water is boiled. Eat only the pulp and juice at the bottom of the bowl, not the skin.
4. Pectin contained in apples has a good detoxification effect and can be used with dietary fiber to clean the intestines. Pectin will become more stable after heating, and it also has the function of "absorbing intestinal bacteria and toxins". The content of polyphenols natural antioxidants in apples will increase greatly after heating. Polyphenols can not only reduce blood sugar, blood lipid, inhibit free radicals, resist oxidation, inflammation and sterilization, but also inhibit the increase of plasma cholesterol and eliminate free radicals in the body. Apples left at home for a long time probably don't taste good now. They can be cooked and eaten. Apple's vitamin C content is very low, so it's not a pity to eat it cooked. Beneficial components such as potassium, pectin, chlorogenic acid and flavonoids can still be retained after heating. The taste will turn sour after boiling. Just add less water and more dates to make it sweet. It is also good to eat apples steamed and baked, or chopped and mixed in pancakes, all of which are delicious.
5. Pears can moisten the lungs and relieve cough, but pears are cold. Eating raw pears in cold weather will make you feel colder. But if the pears are boiled, the situation is completely different. Ripe pears remove the coldness, the pear skin will become slightly bitter, and the effect of drying and moistening the lungs will be completely released. Lignin in pear seeds originally belongs to insoluble fiber, but it will dissolve in the intestine after heating, and harmful cholesterol will be taken out of the body. "Rock sugar Sydney" is the most common cooking method of Sydney. The method is simple. Cut Sydney into pieces, add appropriate amount of cold water and rock sugar and cook for half an hour. Pear can moisten lung, promote fluid production, clear away heat and resolve phlegm. It is best to eat rock candy Sydney to nourish yin and moisten the lungs in winter. Patients with chronic tracheitis and chronic pharyngitis can also eat some rock sugar Sydney for diet therapy.
Dried fruit has high nutritional value, and it has a good health care effect when eaten in moderation.
When it comes to the benefits of fruits, we are all familiar with them, but when it comes to dried fruits, we don't understand them. Dried fruit has many advantages that people tend to overlook. Let's take stock together.
1. When you can eat all the fiber in the peel and eat fruit, people often spit and peel off the skin, otherwise it will be difficult to swallow. In fact, the peel is the place with the highest dietary fiber content in fruits. After drying, dietary fiber is completely unaffected. Such as raisins, cellulose is not wasted at all.
2. Protease and unpolymerized tannin have no risk of harming digestive tract. Fresh fruits often contain active protease and tannin. Tannin has a strong antioxidant effect, and the damage to digestive tract mucosa is also quite fierce for people with indigestion. Traditional health care often advises people with indigestion not to eat fruit on an empty stomach. Actually, I'm afraid of them to a great extent. Once the fruit is dried, protease will be inactivated and tannin will be polymerized, which will greatly reduce the stimulation to the digestive tract.
3. All the mineral components are preserved. Although dried fruit will lose vitamin C, minerals such as potassium, magnesium and iron will not be lost, and will be concentrated because of water loss, and the content is higher than that of fresh fruit. Therefore, all kinds of dried fruits are good sources of potassium. Raisins are rich in potassium and iron, which is incomparable to white sugar or even brown sugar.
4. Most of the antioxidant components remain. For red, blue and purple-black fruits, anthocyanins are particularly rich in antioxidant substances and will be concentrated after drying. Especially those dried red raisins and blackcurrants with thick skin and deep color, if eaten with skin, the health care effect is better.
5. It is easy to carry and store, and it is a high-quality snack. Although the sugar content of dried fruit is similar to that of rice, it belongs to high-calorie food, but you can put it in a small bag and eat only a handful at a time, which makes it easier to control the quantity, so as not to stop eating like fresh fruit, and always fear that it will go bad after eating.
Tip: Before eating dried fruit, learn to distinguish between "dried fruit", "preserved fruit" and "preserved fruit". Red dates, raisins, dried longan, dried persimmon and dried apple are all dried fruits. These products are easily available in online stores. They are characterized by no sugar, no salt, no oil and no additives, and they are completely in a natural state after drying and concentration. Their tastes are different, such as dried apples are tough and chewy, dried persimmons are elastic and delicate, and so on. Toughness and the feeling of drawing are the result of close cooperation between a lot of sugar and pectin. Candied fruit and candied fruit are not. They all add a lot of sugar, or add sugar to refuel, sugar to salt and so on. And many of them contain a variety of food additives, in order to increase flavor or help preserve. But because of the addition of these things, their nutritional and health care values are greatly reduced. Even imported products are the same. Dried blueberries with a lot of sugar and dried fruits and vegetables with a lot of oil are not healthy.
