2, eliminate eye bags: Sticking potato chips on the eyes can reduce eye bags, and it is also effective for small ones. It is said that applying potato juice to nails can make them more delicate and smooth.
Verb (short for verb) mushroom
1, rich in nutrition: the content of protein in mushrooms is higher than that in common fruits. Contains a variety of vitamins and rich minerals such as calcium and iron. Most importantly, it also contains eight essential amino acids that the human body cannot synthesize.
2, improve immunity: after the mushroom is irradiated by the sun, the special substances it contains will be converted into vitamin D, which will help to enhance resistance after being absorbed by the human body. Mushrooms can also produce more interferon and eliminate toxins in the body, so mushrooms also have a certain effect on preventing colds.
3, weight loss: mushrooms are rich in inorganic substances, vitamins, protein and other nutrients, but the calories are very low, and regular eating will not get fat. Moreover, mushrooms contain high plant cellulose, which can prevent constipation and reduce the cholesterol content in the blood. Vitamin C in mushrooms is much higher than that in common fruits, which can promote human metabolism.
Six, soybean
1, tumor inhibition: isoflavones and genistein in beans are powerful antioxidants, which are very helpful to reduce female breast cancer and cervical cancer.
2. Stay away from coronary heart disease: Most of the fat in soybean is unsaturated fatty acid, which is a good food to prevent coronary heart disease, hypertension and arteriosclerosis.
3, anti-aging: black beans not only have a strong role in preventing arteriosclerosis, but also can eliminate free radicals in the body and delay aging.
Seven, eggs
1, enhance memory: lecithin, triglyceride, cholesterol, yolk protein, etc. Eggs have a great effect on the development of nervous system and body, and can also block the memory decline to some extent.
2. Beauty: It is a simple and economical beauty method to beat hot eggs on the face for a few minutes to promote the vasodilation of facial skin, enhance blood circulation, and absorb nutrients by the skin, and then shrink pores and blood vessels with cold water.

Eight, walnuts
1, Jiannao: The nutritional value of one catty of walnuts is equivalent to five catties of eggs or nine catties of milk. Protein in walnuts contains lysine, which is very important to the human body and beneficial to the brain. Therefore, people with dizziness, forgetfulness, palpitations and other symptoms may wish to try some walnuts.
2, moisturizing: eat a few walnuts a day, or drink walnut porridge, stick to it for a while, you will feel delicate and moist skin.
Nine, fish
1, eat a good mood: there is a special fatty acid in fish, which is related to the "happy hormone" in the human brain. Therefore, when people are depressed, they will eat more fish consciously, and their mood will gradually get better. Fish is rich in magnesium and boron, and magnesium has a sedative effect. Eating fish often can relieve tension.
2, the gospel of smokers: one of the early symptoms of arteriosclerosis is endothelial dysfunction (that is, the artery can not expand), smoking will cause endothelial dysfunction. But amino acids in fish can prevent arteriosclerosis. So if you can't give up smoking for a while, eat more fish.
Orange
1, cancer prevention: A medium-sized orange can provide people with vitamin C for one day, and improve the body's ability to resist bacterial invasion. Oranges can scavenge harmful free radicals in the body and inhibit the growth of tumor cells. Among all fruits, citrus contains the highest antioxidant substances, including more than 60 flavonoids and 17 carotenoids. Flavonoids have anti-inflammatory, blood vessel strengthening and blood coagulation inhibiting effects. Carotenoids have a strong antioxidant effect. These ingredients make oranges inhibit the occurrence of various cancers.
2, orange juice can not replace fresh orange: oranges contain minerals and inorganic salts such as vitamin A, magnesium, zinc, calcium, iron and potassium, as well as fiber and pectin. If you only drink orange juice, the effect will be greatly reduced. Because in the process of juicing, almost all fibers are lost, as are vitamin C, flavonoids and carotenoids.
Is thin milk a quality problem? No, sterilized and homogenized milk looks thin, but its nutritional value is not lower than that of thicker milk. The milk with butter on the inner wall of the package is because of its high fat content. After a certain period of time, the fat will float and form grease. Such milk is difficult to be fully absorbed by the human body and will cause unnecessary waste. Even some milk producers often take advantage of people's misunderstanding and add thickener to milk to deceive consumers.
Cooking with boiling water is nutritious.
Sometimes hard work can't get good results, just like cooking with cold water. After rice is soaked in cold water, it will absorb a lot of water and expand, so that most of the nutrients in aleurone layer can be dissolved in water. With the increase of water temperature and evaporation of water, vitamin b 1 dissolved in water will partially escape and be destroyed when heated in alkaline water. In addition, some urban residents should add water purifying agent and bleaching powder to drinking water during purification treatment. Although they are harmless to human body and can kill bacteria in water, they can also directly destroy and decompose vitamin b 1, resulting in the loss of nutrients in rice.
The best way to cook is to boil the water before adding the rice, so that the rice will be heated while absorbing water, and the protein will be solidified by heating, leaving the rice grains intact. Part of the gelatinized starch escapes and dissolves in the soup, which makes the porridge sticky. Moreover, in the process of boiling water, partially concentrated protein can protect vitamin b 1 and prevent it from dissolving in water. After adding rice, the kettle boils slowly and the steam decreases. This makes the storage of vitamin b 1 higher than that of rice cooked in cold water, and the cooked rice tastes better.
Adding a few drops of salad to the cooking water can make the rice grains crystal clear. A few drops of lemon juice can soften rice. To cook a pot of fluffy rice, sprinkle a little salt in the pot. Adding vinegar to cooking can prevent rice from turning sour. When heating leftovers, adding a small amount of salt to the water in the steamer can remove the odor of leftovers.
You don't have to use new rice if you want to eat fragrant rice. Cooking with tea can get a meal with good color, smell and taste. Cooking with tea also has the benefits of relieving boredom, cleaning the mouth, dissolving food and preventing it. Eating tea and rice regularly can soften blood vessels, reduce blood lipids and prevent and treat them. In addition, tea polyphenols can block the synthesis of nitrosamines in human body. Amines and nitrites are widely found in human body, and carcinogenic nitrosamines are easily generated at 37℃ and proper acidity. Cooking with tea leaves can effectively prevent the formation of nitrosamines, thus achieving the purpose of preventing and treating digestive tract tumors.
It is not good to eat coarse grains often.
Coarse grains contain a lot of cellulose. If people are between 25 and 35 years old, consuming too much fiber will affect the absorption of protein, inorganic salts and some substances, and even affect the reproductive capacity. Eating coarse grains should not only be divided into age groups, but also be careful not to blindly follow the trend.
For example, the high phytic acid content in buckwheat, oats and corn will hinder the absorption of calcium, iron, zinc and phosphorus and the metabolic balance of minerals in the intestine. Therefore, it is necessary to increase the intake of these minerals when eating coarse grains.
For another example, cholesterol in food will be excreted from the intestine with the fiber in coarse grains. The decrease of cholesterol absorption will lead to the decrease of female hormone synthesis and affect the normal development of uterus. Therefore, the daily fiber intake of adolescent girls should not exceed 20 grams. Because the gastrointestinal function of the elderly is weakened, they will eat more coarse grains and their function will be weakened. Over time, it will lead to malnutrition. The daily intake of cellulose for the elderly should not exceed 25g to 35g.
Black rice is a kind of rice used for both medicine and food, and its vitamins and amino acids are higher than ordinary rice. Studies show that the darker the color of rice, the more obvious the anti-aging effect of epidermal pigment. Of course, the effect of black rice pigment is the strongest among all kinds of rice. In addition, this pigment is also rich in flavonoids active substances, which is five times that of white rice, and plays a great role in preventing arteriosclerosis. In addition, black rice contains more dietary fiber, and the digestion speed of starch is slow, and the glycemic index is 87 (white rice). Minerals such as potassium and magnesium in black rice are also beneficial to control blood pressure and reduce the risk of illness. Therefore, diabetics and patients with cardiovascular diseases can eat black rice as part of their diet.
At present, there are two kinds of adulteration of black rice in the market. One is that inferior or inferior black rice stored for a long time is dyed and sold as inferior; The other is to dye ordinary rice and sell it as black rice. Consumers can buy black rice from the following aspects: First, look at the color and appearance of black rice. Generally, black rice has luster, uniform particle size, less broken rice and cracked waist (with cracks on the particles), no moth-eaten and no impurities. Inferior inferior black rice has dim color, uneven particle size, poor plumpness, more broken rice, insects and caking. For dyed black rice, because the black of black rice is concentrated in the cortex, the endosperm is still white. Therefore, consumers can scrape off all the outer cortex of rice grains and observe whether the rice grains are white. If it is white, it is probably artificially dyed black rice.
Second, smell the black rice. Take a small amount of black rice in your hand, exhale hot air at the black rice, and then smell it immediately. High-quality black rice has normal fragrance and no other peculiar smell. Those with slight odor or musty, sour, putrid and peculiar smell are inferior and inferior black rice.
Three kinds of people eat less soybeans.
Dear friends, bean products have always been the main food in our lives, but not everyone does. Soybean contains a chemical called phytoestrogen, which can promote the growth of estrogen receptor cells. About 4% of the women who ate soy products developed endometrial hyperplasia, while none of the women who ate placebo developed endometrial hyperplasia. Moreover, pregnant women or pregnant women eating soybeans may endanger the reproductive development of baby boys. Therefore, it is better to be careful when eating soy products during pregnancy.
The chemical components contained in soybean can "simulate" the effect of estrogen, resulting in a decrease in the number of * * * *. This result is very worrying, because it may cause the decline of male reproductive function, which is abnormal for many men.
China tofu
Tofu is not only a national dish in China, but also has made many contributions to disease prevention and health care. It's really "the more Han Xinbing, the better". But friends, you can't eat too much, you need good things.
Question 1: The tofu that causes indigestion is rich in protein. Eating too much at a time not only hinders the absorption of iron, but also easily causes protein's indigestion, diarrhea and other discomfort symptoms.
Question 2: Promoting the decline of renal function. Under normal circumstances, the plants that people like protein eat in the body undergo metabolism, and most of them become nitrogen-containing wastes, which are excreted by the kidneys. When people get old, the ability of the kidneys to excrete waste decreases. At this time, if you don't pay attention to your diet, eat a lot of tofu and take in too much plant protein, it will inevitably increase the nitrogen-containing waste produced in your body, increase the burden on your kidneys and be harmful to your health.
Question 3: Soybean products that promote arteriosclerosis are rich in methionine, which can be converted into cysteine under the action of enzymes. It will damage the endothelial cells of the arterial wall, make cholesterol and triglycerides deposit on the arterial wall, and lead to the formation of arteriosclerosis.
Question 4: Lead to iodine deficiency. Soybeans that make tofu contain saponin, which can not only prevent atherosclerosis, but also accelerate the excretion of iodine in the body. Long-term excessive consumption of tofu can easily lead to iodine deficiency, leading to iodine deficiency disorders.
Question 5: Tofu that promotes gout attack contains more purines. Gout patients with abnormal purine metabolism and patients with elevated serum uric acid concentration are prone to gout attacks, especially gout patients.
Traditional Chinese medicine believes that people with cold tofu and stomach, people who are prone to diarrhea, abdominal distension, spleen deficiency and kidney deficiency and frequent nocturnal emission should not eat more.
About wild vegetables
Wild vegetables have always been regarded as ideal dual-purpose vegetables for medicine and food, and have the reputation of "natural health food". Come to see me carefully.
Guo Fu Cai's instant sweet potato is rich in nutrition, sweet in taste, and has health-care functions such as invigorating spleen, regulating stomach and benefiting qi. The edible part is the tender stem and leaf of its rattan tip, which tastes crisp and sweet, and has the effects of clearing away heat and toxic materials, nourishing kidney and moistening lung.

Not edible. People who are allergic to painkillers, sulfonamides or certain substances should be careful when eating wild vegetables. Eat a small amount for the first time. If there are allergic or toxic symptoms such as itching, edema, rash or subcutaneous hemorrhage after eating, you should stop eating wild vegetables and go to the hospital for treatment to avoid damaging liver and kidney function. In addition, many wild vegetables, such as wild amaranth, willow bud, wild alfalfa, Ailanthus altissima, etc., should be blanched with boiling water before eating, rinsed with clear water several times, drained of bitter water before cooking. When picking wild vegetables, you must distinguish clearly. Wild vegetables should not be stored for a long time, so it is better to eat them fresh.
About fast food
One of the misunderstandings: "Instant noodles are undernourished and lack protein, vitamins and mineral elements."
Instant noodles are convenient foods, including bread, rice, pizza, hamburgers, sandwiches, potato chips, cakes, biscuits, fried dough sticks, steamed bread, steamed buns and so on. 12 kinds of staple food and leisure convenience food, none of which can be called protein, have complete contents of fat, carbohydrates, vitamins, mineral elements and dietary fiber, and are reasonably matched, which completely conforms to the ideal food recommended by Dietary Guide for China Residents. The positioning of instant noodle products determines that its consumers are mainly busy consumer groups such as work, school, part-time job and field work in modern life. However, the above 12 kinds of convenience foods can not fully meet their requirements of saving time and trouble, being cheap, eating in various ways and being delicious. Only fried instant noodles can do it, which is why instant noodles have been favored by people since their birth.
In order to make up for the deficiency of protein and trace elements in instant noodles, we can supplement the required nutrition according to our working environment, physical condition, economic situation and preferences. For example, some Singaporean consumers put some meatballs and fish balls in noodle soup when making instant noodles. This is not only convenient and fast, but also can supplement nutrition as needed and become a veritable delicious nutritious staple food.
Myth 2: "High oil content and salt content are not conducive to."
At present, fried instant noodles account for more than 90% of the total output. The oil content of domestic famous brand fried instant noodles is 18% to 20%, and the salt content is 1.6% to 2%, which is basically consistent with the international standards.
Other convenience foods with high oil content, such as:
1. The oil content of fried potato chips, potato chips and corn chips is 35% ~ 50%.
2. The oil content of fried dough sticks and oil cakes is 30% to 45%, and the salt content is 2%.
3. Biscuits: The oil content of biscuits is as high as 35%, crispy biscuits are as high as 15%, soda biscuits are as high as 15%, and waffles are as high as 35%.
4. Bread: The highest oil content is 28%, the salt content is 1.6% to 2%, the baking temperature is 190℃ to 2 10℃, and the baking time is 22 minutes.
5. Pizza: oil content 16% to 24%, salt content less than 2%, baking temperature℃, baking time 15 minutes.
As can be seen from the above, the oil content of fried instant noodles is much lower than that of fried dough sticks, French fries and potato chips, and is basically the same as that of some biscuits, colored bread and pizza.
Remember to bathe the kelp.
Most of the dried kelp we bought in the market is high in arsenic because of seawater pollution, so be careful when eating it. Arsenic and arsenic compounds are generally toxic and can cause acute and chronic arsenic poisoning. Therefore, countries have strict regulations on arsenic content when formulating food hygiene standards. The arsenic content of dried kelp has greatly exceeded the standard.
The experiment showed that the arsenic content of dried kelp was still as high as 5 mg/kg after soaking in water for 5 hours to 10 hour. After soaking in water for 24 hours, its arsenic content can reach the safe edible standard.
Kelp has been soaked for a long time, and there is a certain loss of nutrients. Among them, vitamin b 1 and nicotinic acid will lose a part, functional trace elements and mannitol will lose more, and iodine will also lose to a certain extent. But these will not have much influence on the nutritional value of kelp. Because the iodine content in kelp is very high, even if a part of it is lost, it can still play a sufficient supplementary role to the human body. Mannitol is a drug for treating brain edema and Japanese encephalitis, which has little effect on healthy people. Moreover, the content of mannitol in kelp is far from the medical dose, so it is not a pity to throw it away.
Eight Dietary Details Affecting Lifelong Health
Although it is a common proverb that "food is the most important thing for the people, and food safety is the first priority", people generally know the importance of eating well, but they often ignore safety and health. Food is the core of survival. When what to eat is no longer a problem, how to eat becomes more and more important and cannot be ignored. This is a life, and a meal can't be sloppy. Good habits will affect your life!
The hiding place of milk
When it comes to heat, we must understand its composition. Although different manufacturers have different brands, the content is mostly nothing more than milk, oligosaccharides, pectin, fructose and spices. Because China people are generally not used to sour yogurt, so manufacturers will add sugar or fructose to flavor it, which also adds a lot of calories. Generally speaking, the calories of yogurt are still higher than milk. To keep slim, we must carefully choose the brand and type of yogurt and limit the consumption, otherwise we will unconsciously consume a lot of calories, which is easy to gain weight and difficult to lose weight!
Faced with all kinds of milk advertisements, many brands of milk products and the selling points hyped by various businesses, you seem to be at a loss when standing in front of the supermarket milk cabinet. As long as you pay attention to avoid "two highs and one low" when buying milk: high temperature, high calcium and low fat, the problem will be solved.
First of all, milk disinfection is not as high as possible. Because the nutrients of milk will be destroyed at high temperature, and the lactose in it will coke at high temperature, the quality of ultra-high temperature sterilized milk is not the best.
Secondly, the higher the calcium content and concentration of milk, the better. At present, the calcium content of milk from different manufacturers is not much different, but some manufacturers artificially increase the calcium content of their products in order to find a selling point, adding chemical calcium to natural milk, but these chemical calcium can not be absorbed by the human body, and will precipitate in the human body over time, and even cause stones.
Finally, the lower the fat in milk, the better, that is, milk is not defatted. Many people are worried that drinking milk will make them fat, so they always choose skim milk. In fact, the fat contained in milk can not be directly converted into human fat, and the proportion of fat contained in natural milk itself is not high, so it is a misunderstanding to think that drinking milk will make you fat. In addition, the nutritional components of skim milk are greatly reduced, which is not conducive to human health.
The thicker the milk, the better? Milk can be artificially thickened at will, and the thicker the better, the longer it lasts on the wall. The quality of milk depends on whether its index content meets the standard. Generally, the protein content of pure milk is about 3 grams per milliliter, and the fat content is about 3.3 grams. Nutrition is the most important thing, so when you buy milk, you should look at the label of the ingredients, and don't just judge whether it is sticky or not. The color of standard pure milk should be slightly milky yellow, with cup hanging, but it won't last long. Sure, it's too thin. If the color is bright, it is like water, not pure milk.
It is wrong to give children too pure milk, because pure milk contains three times as much protein as breast milk, and children are too young to digest and absorb too much nutrition. Drinking too pure milk will cause children to have diarrhea and refuse to eat, so when drinking milk for children, you should change some water and appropriate amount of sugar to facilitate digestion, but the water and sugar must be quantitative, not too much.
