How to identify the authenticity of foreign fruit Kedong

According to reports, there are currently more than 100 kinds of foreign fruits on the market, and the people are familiar with raisins, snake fruits, oranges, Brin, crystal pears, kiwis, lemons and mangoes. Because the imported foreign fruits are one in a hundred, plus advanced foreign preservation technology and avant-garde packaging technology, they are uniform in size, bright in color and rich in texture, and their preservation period has grown into the common characteristics of foreign fruits.

Below, we will briefly introduce the types of people who spend the most.

Red Earth: Native to the United States and Chile. Unlike the brownish red of grapes, red grapes are deep red. The fruit shape is consistent, the size is even, and there is no loose material in the whole hanging. It's harder to hold in your hand. The taste is crisp and sweet, with a fibrous feeling. When grapes are pinched, the skin and meat are easily separated. However, the skin of red raisins is thin, and the flesh is difficult to separate, so it can be preserved for a long time. Under normal circumstances (without taking any measures), it can be stored for about 15 days.

American orange: native to the United States and Australia. Known as the beautiful orange, it is similar to the navel orange in Zigui and Fengjie, Hubei. Big, rough skin, not as smooth as navel orange. It tastes moist and crisp and sweet, but the fiber is thick and not as delicate as navel orange. Under normal circumstances, it can be stored for more than 30 days. Snake fruit: Originated in the United States, similar to the new red star apple produced in Shaanxi and Gansu. Snake fruit is red and slightly sweet and sour.

Kiwifruit: The biggest difference from Kiwifruit is that Kiwifruit is delicious only when it is hard, but it must be cooked to be delicious and hard to be astringent. Under normal circumstances, kiwifruit can be preserved for about 20 days. Brin: Originally from the United States, it is similar to Jinhua Mei in China. The fruit shape is uniform in size, and the surface is smooth and delicate, showing red. When it is hard to eat, it tastes the same as Jinhua dialect plum, but it has a lot of nuclear meat and tastes particularly good. Under normal circumstances, it can be kept for about 20 days.

Crystal Pear: Originated in Japan, it is only one word apart from the Crystal Yali pear in Hebei, but its appearance and taste are quite different. Crystal pear is very big, and it feels like falling in your hand. It is dark yellow. Crystal pear is unique in that its shape is not like a pear, but like an apple, which is particularly crisp to eat. Under normal circumstances, it can be kept for about 30 days.

Analysis of hypertension and lung cancer and the defects of China's eating habits

Dr. holman, an American nutritionist, spent a year investigating Chinese and Western diets and came to the conclusion that China's diet has the following shortcomings:

(1) When cooking, people like to use more salt, which is one of the important risk factors of hypertension.

(2) There is no habit of eating separately, which is easy to infect each other.

(3) Eat three meals a day and eat more at each meal. The balanced distribution of heat during the day can enhance the metabolism of the human body and avoid excessive heat at night. The number of meals a day is related to health. The less you eat, the more likely you are to get some diseases.

(d) Large-scale hospitality and overeating are not only wasteful, but also extremely harmful to health.

(5) The number of women suffering from lung cancer in China is significantly higher than that in the United States, which may be due to inhaling more oil fumes.

There are strong carcinogens in fried fish.

Evening News: Dr. Zhang, a doctor of preventive medicine in China, has confirmed through years of research that there is a strong carcinogen-heterocyclic amine in fried fish.

It was also found that the formation of heterocyclic amines was mainly affected by frying and baking temperature, followed by frying and baking time. When the frying temperature is below 200℃, the amount of heterocyclic amines is very small. If the frying temperature exceeds 200℃ and the frying time is less than 2 minutes, the amount of heterocyclic amines is also very small; Hanging a layer of starch paste on fried fish before frying can also prevent the formation of heterocyclic amines.

In addition, according to researchers in California, there is a mutation source in meat cooked or fried at high temperature. The researchers used monoclonal antibodies to detect beef, chicken and fish cooked at high temperature, and the results showed that 10 carcinogens were detected. This study confirmed that the source of variation is not caused by burning meat with charcoal fire and other heat sources, but the product of the meat itself when it is heated above 200℃.

When do you take the medicine? Pay attention to Ma Zuxiang before and after meals.

The relationship between oral medication and eating order has an important influence on the digestion and absorption of drugs.

Common drugs that should be taken on an empty stomach before meals are: intestinal anti-infective drugs, which require a high concentration of drugs in the intestine, and eating will reduce the drug concentration; Gastric wall protective drugs. After taking these drugs, the drugs will disperse and form a protective film on the gastric wall. When taken with food or after meals, drugs will be mixed with food and will not play its due role. Enteric-coated tablets can only be digested and absorbed after reaching the intestine, which will affect the emptying of the stomach and delay its digestion and absorption; Drugs such as rifampicin and ampicillin should also be taken before meals, because they are easily absorbed by cellulose in food. In addition, some anthelmintics and laxatives should also be taken before meals.

Fat-soluble drugs such as cod liver oil are commonly used in meals, because fat-soluble drugs can be dissolved in the fat in food and absorbed more easily; In addition, when taken with food, it helps digestion better.

Most drugs can be taken after meals, especially those with severe gastrointestinal reaction, which can reduce the stimulation of drugs.

Not eating meat will damage immunity.

Nowadays, vegetarianism or abstinence from eating red meat has become a healthy trend. The World Health Organization (WHO) has proposed a healthy diet that reduces the intake of foods with high saturated fat and cholesterol and eats more fruits and vegetables with high fiber. In fact, a top British nutritionist holds the opposite view that vegetarians who don't eat red meat will make their bodies more vulnerable to bacterial infections and diseases.

The BBC reported on May 7th that Professor Picarda, Director-General of the British Nutrition Foundation, pointed out at a nutritionist's meeting in Stratford, England that there is one kilogram of bacteria in the human stomach that is responsible for digesting omnivores. There is evidence that if these bacteria are left idle, pathogens (including bacteria) will be more likely to take advantage of it and make people sick.

He also pointed out that human teeth, jawbones and intestines and stomach have evolved to cope with meat and vegetables, and meat contains many nutrients beneficial to human body, such as iron for blood, vitamin D for bones and protein and fatty acids for growth, so meat is indispensable in human diet.

Drinking tea may be a good way to protect your teeth.

According to recent research by American and British scientists, drinking tea may be a good way to protect teeth.

The research team of the Department of Dentistry, University of Illinois, USA chose the black tea that westerners often drink for the experiment. They asked volunteers to rinse their mouths with black tea for 30 seconds every 3 minutes. After 5 repetitions, dental plaque bacteria stop secreting acids that corrode teeth and cause dental caries.

The British Dental Association believes that both black tea and green tea can help to remove or inhibit dental plaque. A spokesman for the association said that dentists believe that tea can be used as a substitute for soda water because tea will not corrode teeth. The spokesman said that the occurrence of dental caries is related to the phenomenon that acidic substances dissolve calcium salts in teeth. After the teeth are eroded by acidic substances, the enamel part gradually dissolves and becomes thinner. When the enamel is completely eroded and the dentin and pulp under the original teeth are exposed, patients will feel severe pain. However, the spokesman said that the role of tea in protecting teeth needs to be further verified, because ordinary tea drinking and clinical trials are not the same thing after all.

Middle-aged women might as well eat some honey often, Wang Jinshan.

Honey is sweet and flat. Honey is different from white honey and yellow honey because of different kinds of bees and honey sources. Fruit nectar (jujube nectar, Sophora japonica nectar) is fragrant, sweet but not sour, clean and bright, without impurities.

The competition in modern society is fierce, especially for middle-aged women, with greater physical and mental pressure. In addition, when people reach middle age, all parts and organs of the body are degenerating. In hot summer, it is easy to make people "dry inside", and symptoms such as dizziness, dizziness, tinnitus, dry mouth, palpitation, chest tightness, insomnia, loss of appetite and constipation follow. Middle-aged women (both young and old) often take honey with warm boiled water to prevent and treat these unspeakable diseases, which has the functions of tonifying the middle-aged and invigorating qi, moistening dryness and calming the wind, calming the five internal organs and calming the nerves. Royal jelly honey is especially top grade. If honey is made into pills or ointment, it has the effect of relieving pain and harmonizing various drugs. When we eat, it is best to take it with warm water not exceeding 60℃. If boiled water is used, it will not only fail to maintain the natural color, fragrance and taste, but also destroy the nutrients. Only vitamin C will lose 1/5 or even 1/2. In addition, people with phlegm-dampness, epigastric fullness and diarrhea should not take it. Middle-aged women might as well eat "honey" often, which is of great benefit to your physical and mental health.

Women ovulate, men can smell it.

American scientists have found that men can tell whether they are ovulating or not from women's body odor, subverting the traditional concept that men can't detect women's ovulation.

Hormones in women will change dramatically during the menstrual cycle. A group of researchers from the University of Texas at Austin tested 50 men, asked them to smell the clothes worn by 17 young women, and then evaluated which one was the most attractive. The results show that even if two dresses are worn by the same woman, men will think the dress she wore during ovulation is sexier and more attractive.
