First, why is kiwifruit known as the "crown of vitamin C"
Vitamin C is an essential nutrient for human body, which cannot be synthesized by human assimilation. Mental depression, fatigue, and serious lack can cause scurvy. The kiwi fruit contains vitamin C 100-420mg per 100g, which is 20-80 times higher than that of apple, 30- 140 times higher than that of pear and 5- 10 times higher than that of citrus. The utilization rate of vitamin C contained in kiwifruit is as high as 94%. The nutrient density is over 57.5, almost twice that of a medium-sized orange.
An adult needs 50-60 mg of vitamin C every day. Eating a small kiwi fruit or a glass of kiwi fruit juice every day can meet the human body's demand for vitamin C.
Second, why can eating more kiwifruit accelerate lead excretion?
Lead is a kind of heavy metal widely used in industrial production, and it is also a poison that can accumulate in organisms. Lead remains in food, fruits and vegetables after using lead-containing pesticides; There is lead dust pollution in the environment and atmosphere. Since 1924, lead has been widely used as an explosion-proof agent in gasoline, resulting in lead in automobile exhaust; When batteries are in use and plastic rubber is in production, lead will also be discharged, polluting the environment. The use of lead alloy, enamel, ceramics and other utensils will lead to lead pollution, and there are also a lot of lead in cosmetics used by women, which has caused lead pollution all over the world. Early lead poisoning is a series of symptoms of neurasthenia, followed by anemia, nephritis, hypertension and chest diseases, which can lead to shock or death. According to research, diseases such as arteriosclerosis, digestive tract ulcer and fundus hemorrhage are also related to lead poisoning.
Kiwifruit is rich in vitamin C, which can combine with lead to form lead ascorbate with little solubility, which is excreted with feces. Moreover, kiwifruit is rich in pectin, which can precipitate lead in the intestine and reduce the absorption of lead. At the same time, kiwifruit is rich in organic selenium, which is an essential trace element for human body and has a strong affinity for heavy metals. In the human body, it can combine with metal poisons such as lead, cadmium, mercury and arsenic to form a metal selenium protein complex and excrete it, protecting the liver, gallbladder, heart and hematopoietic system.
With the increase of the number of cars, lead pollution is more and more harmful to human body. While the government is enforcing unleaded gasoline, for the sake of health, we might as well take the initiative to eat more kiwifruit.
Third, why can kiwifruit be "turned into a big one"
With the development of food nutrition, since the 1970s, people have realized that crude fiber in plant foods has a good health care and promotion effect on intestines, and can prevent constipation, inflammation, hemorrhoids, colon cancer, cardiovascular diseases, diabetes and other diseases. It is beneficial to the body and is called "the sixth nutrient element". Crude fiber can stimulate intestinal peristalsis, accelerate the removal of intestinal waste, reduce intestinal reabsorption of carcinogens such as sulfide and fecal odor, and promote defecation; Crude fiber is insoluble in water, which can reduce cholesterol and other lipids in blood and prevent atherosclerosis and cardiovascular diseases.
Kiwi contains a lot of fiber and good quality, which is beyond people's expectation. It is considered by the US Food and Drug Administration (FDA) as the best source of dietary fiber. Its average crude fiber is 1800mg/ 100g, which is three times that of a cup of celery. The fiber content of kiwifruit per 140g is 5-25 times that of most ancient foods. The content of dietary fiber in kiwifruit is much higher than that of ordinary vegetables and various crops, and dietary fiber plays a more important role in medicine.
"A day without defecation is equivalent to smoking three packs of cigarettes". Shit is an important event for ordinary people every day. If you don't shit for a day, the problem will be big. Because it includes three meals a day of rice, steamed bread, pork, vegetables and so on. Almost all foods stay in the human intestine for more than 12 hours, and the toxins released are about equivalent to the harm of three packs of cigarettes. Today, eating more crude fiber is nutritious and fashionable. Eating kiwi fruit every day is the "sword on the side" to make your stomach smooth every day.
4. Can kiwi fruit juice relieve hangover?
Kiwi fruit juice contains a variety of organic acids, trace elements and carbohydrates, which can stimulate the secretion of saliva and gastric juice and accelerate gastrointestinal peristalsis; It can dilute blood and summarize ethanol concentration, and promote the excretion of metabolic waste by kidney; It can also enhance the ability of liver to decompose toxins and reduce the formation of toxic metabolites.
"Drinking a cup of kiwi fruit will change the amount of alcohol from four to six." In fact, this is an illusion when drinking happily. Kiwi fruit is not a hangover cure for thousands of cups because it can't decompose ethanol. However, drinking kiwi fruit juice in a timely and proper amount after drinking can promote the production of body fluid to quench thirst, promote digestion, protect the liver and make the body recover as soon as possible. A glass of kiwi fruit juice while drinking will make you feel more comfortable.
5. What are the benefits of rich calcium in kiwifruit?
Calcium is an essential element to maintain health and the most inorganic element in human body, accounting for 1.5%-2% of body weight. Adults contain 850-1200g of calcium, 99% of which is combined with phosphorus and concentrated in bones and teeth, and a small amount of calcium exists in the soft tissues and blood of the body, which plays an important role in various physiological and biological processes of the body. 1992 The results of the national nutrition survey show that calcium obtained from diet is generally insufficient in both urban and rural areas, children, adults and the elderly. In cities, the calcium intake of 565,438+0% men and 60% women is less than half of the required amount, and the intake of rural children is even lower. China Nutrition Society suggests eating more milk and fruit products with high calcium content, and supplementing calcium appropriately if possible, but calcium supplements should not be abused.
The content of calcium in kiwifruit is quite high, about 58mg/ 100g, which is higher than almost all fruits. Moreover, the content of sodium in kiwifruit is almost zero, which is incomparable to other fruits, and it is of great significance to improve the nutritional structure of calcium deficiency and sodium increase that is common in people's diets in China at present. If you want to easily supplement calcium from eating fruits, the most economical and safest way is to eat kiwifruit with high calcium and low sodium.
6. Why is kiwi fruit the best way to eat potassium instead of sodium in patients with hypertension?
Potassium is a mineral that can lower blood pressure. There are three beneficial ways to regulate blood pressure: 1. The diuretic effect of potassium reduces the amount of liquid in the body and the water pumped by the heart, thus reducing the workload of the heart and blood vessels and lowering blood pressure; 2. Potassium can inhibit the enzymes and hormones that cause hypertension; 3. Potassium can relax the muscles of blood vessel wall, thus reducing the resistance of blood flow and lowering blood pressure.
In addition, potassium can maintain cell moisture, enhance its activity and help the body regain its vitality. Sweating in high temperature environment, physical exercise or summer, more potassium ions are lost with sweat, which is easy to cause hypokalemia, fatigue, dizziness, headache, anorexia and other symptoms.
The most effective way to prevent potassium deficiency is to eat more fresh vegetables and fruits rich in potassium. When a person needs potassium temporarily, many doctors suggest eating a banana or an orange. In fact, the potassium content of kiwifruit is much higher than that of bananas and oranges. A banana with a length of 15cm contains about 370mg of potassium, a 200g orange contains 270-3 10 mg, and the average potassium content of 100 g kiwifruit exceeds 320mg. Kiwi is the most effective natural potassium source in dietotherapy. In some countries, kiwifruit health drinks are used to supplement potassium deficiency caused by high temperature environment or physical exercise.
There are more than 1 100 million hypertensive patients in China, and diet therapy is the top priority of hypertension treatment. Proper salt (sodium) restriction and high potassium intake are beneficial to the prevention and reduction of hypertension. In order to achieve a low-sodium diet, potassium is also an effective substitute for sodium. Eating kiwi fruit every day can help you lower your blood pressure easily.
7. Why is eating kiwi fruit equivalent to "the fourth nutritious meal"?
The vitamin E in 140g kiwifruit is about 10% of that in American RDA, and it is not found in seeds, nuts and their oils all over the world. In developed countries such as Europe and America, the supplement of natural vitamin E is called "the fourth nutritious meal".
As early as the early 1960s, several research institutions in the United States and Britain found that vitamin E has the magical effect of doubling the life span of human cells. The lack of vitamin E in human body leads to the rapid increase of serum cholesterol concentration, accelerated aging of arteries, obstructive thrombosis and even death.
Recent studies also show that vitamin E can prevent the premature appearance of senile plaques and has obvious anti-cancer effects: it can relieve fatigue caused by lack of sleep, resist aging and improve sexual function to treat menopausal syndrome in middle-aged and elderly people; It has a good effect on protecting fetus and preventing neonatal jaundice and hemolytic anemia. Healthy new nutrition, starting from kiwifruit.
8. Why is eating selenium-enriched kiwifruit a way of life to supplement selenium?
Selenium is one of the essential trace elements for human body 14. Scientific research shows that selenium is an important food source antioxidant, which can protect biofilm from damage and maintain the normal function of cells. Selenium can alleviate the acute injury of aflatoxin B 1, reduce the necrosis and mortality of the central lobule of the liver, protect the cardiovascular system and maintain myocardial health. In addition, selenium can also promote growth, protect visual organs and resist tumors. China is one of the selenium-deficient countries. According to the survey results of dietary selenium intake of residents in 24 provinces and cities in China, the minimum selenium intake per person per day is 8.7 micrograms, with an average of 36.7 micrograms. Based on the recommended daily selenium intake of China residents proposed by China Nutrition Society and approved by the Ministry of Health, the average intake is 20-30% lower than the recommended amount, and the minimum intake is more than 80% lower than the recommended amount, so the selenium nutrition status of China residents is poor. More than 40 countries and regions in the world are deficient in selenium, and 22 provinces, municipalities and autonomous regions in China are deficient in selenium.
How to supplement selenium has always been a topic of concern in the medical and food fields, and it is also a difficult problem. Jishou University and Laodie Company take advantage of Xiangxi as a selenium-rich area to improve the selenium content in kiwifruit through soil root absorption. This kind of selenium-enriched kiwifruit product, which is developed from cultivated selenium-enriched kiwifruit, has created a safe, practical and living selenium supplement method and is at the leading level in kiwifruit development and research at home and abroad. The popularization and application of this technology product will help to improve the selenium deficiency in people's diet in some selenium-deficient and selenium-deficient areas in China and improve people's health level. Lifestyle selenium supplementation begins with selenium-enriched kiwifruit.
9. Why do you say that eating kiwi fruit can relieve depression?
Nutritionists at Rutgers University, the most authoritative food science research center in the United States, have found that kiwifruit contains serum-promoting hormones, which can help people who are often troubled by stress or in external high-pressure environment to increase the serum-promoting hormones in the human body, thus helping people to relieve their emotions, reduce fatigue and keep calm.
The latest medical research shows that adult depression is related to the lack of brain nervousness. The serum accelerant contained in kiwifruit has the function of stabilizing mood and calming mood. In addition, there is natural inositol in kiwifruit, which contributes to brain activity, so it can help depressed people get out of the emotional trough and has a magical effect of nourishing the brain and nourishing the heart.
When the boss is angry, the children cry, the students can't sleep in the final exam, and when they are depressed and stressed, a glass of kiwi fruit juice will calm them down. Kiwifruit every day, in a good mood every day.
X. Kiwifruit Why is Wang Su called' the pride of China'?
Wang Su capsule, made of the essence extracted from kiwifruit by Hunan Laodie Agricultural Science and Technology Development Co., Ltd. and Jishou University for five years, is rich in a variety of unsaturated fatty acids, natural ve, trace element selenium and a variety of bioactive substances. Linoleic acid and linolenic acid, two essential fatty acids for human body, are as high as 60%, especially linolenic acid, which is known as "Wang Zhongwang".
Long-term research results at home and abroad show that linoleic acid and linolenic acid, as essential fatty acids, can promote the metabolism of cholesterol and lipids, promote the formation of animal sperm and protect the skin from X-ray damage. Linolenic acid can effectively prevent and treat cardiovascular diseases, obviously reduce blood lipid and effectively prevent thrombosis; At the same time, enhance human immunity. In addition, linolenic acid has obvious effects in preventing skin aging, delaying aging, resisting asthma, arthritis, gout, allergic reaction, promoting hair growth, preventing constipation and hemorrhoids. At present, linolenic acid is used as a nutritional additive and functional food in 30 countries and regions such as the United States and Britain.
200 1, 1 1, the research group entrusted Jishou University and affiliated hospitals to conduct a two-month clinical study on 42 patients with hyperlipidemia who took Wang Su. The results showed that 70.7% patients' cholesterol (TC) level decreased significantly, with an average decrease of 0.95 mmol/L; 68% patients' triglyceride level decreased obviously, 54% patients' low density lipoprotein (LDL-C) decreased, and 36% patients' high density lipoprotein (HDL-C) increased. The magical function of Laodiewangsu in regulating blood lipid is at the international leading level.
Wangsu products fill the gap at home and abroad, and are new scientific and technological products in Hunan Province. The research and development project of Laodie Wangsu is included in the National Spark Plan and the National Torch Plan approved by the Ministry of Science and Technology, and it is a national agricultural scientific and technological achievements transformation fund support project approved by the Ministry of Science and Technology and the Ministry of Finance. The appearance of Wang Su, the old butterfly fruit, has improved the international status of kiwifruit in China. Officials from the United Nations and the World Bank and experts from Japanese, Italian, New Zealand and other countries came to Xiangxi, China to inspect and wipe, and praised Kiwi Wang Su as "the pride of China".
XI。 Why does kiwifruit have a bright future in China?
China is the origin of kiwifruit, but kiwifruit is the "youngest" fruit in China. 199 1 began to develop. With the rise of kiwifruit consumption fever in developed countries and the improvement of people's living standards in China, China's kiwifruit planting area has surpassed Italy, New Zealand and other developed countries, ranking first in the world, and kiwifruit consumption fever has quietly appeared in China. Take Xiangxi Autonomous Prefecture, one of the three main producing areas of kiwifruit in China, for example, the planting area of kiwifruit increased from 900,000 mu in 1998 to 50,000 mu in 2002, the production and sales of fresh fruit increased from 300,000 tons to 20,000 tons, the production capacity of kiwifruit juice and its deep-processed products increased from 10 tons to 20,000 tons, and the output of kiwifruit deep-processed products increased from 20 million tons to 20 million tons.
In 2000, China's per capita fruit possession reached 50 kg, but due to backward processing, the per capita consumption of fruit juice was 0.9 kg, which was only 1/7 of the world average and 1/30- 1/40 of the developed countries such as the United States. Because fruit juice is superior to fresh fruit in health, safety, nutrition, preservation and use, drinking fruit juice has become a major trend of fruit consumption in the world, and the proportion of eating native fruit only accounts for about 10-20% of fruit consumption. In big cities such as Beijing and Shanghai, juice drinks have become people's first choice (all countries in the world have strict production and hygiene standards for juice drinks, and the juice drinks mentioned here do not include freshly squeezed juice made by household juicers, which is very simple in families and restaurants). Eating more fruits is good for health, which has become the common sense of most people in China. With China's entry into WTO, the concepts of health, safety, nutrition and convenience of fruit juice consumption will be deeply rooted in people's hearts, and fruit juice consumption fever is in the ascendant in China. Kiwi, as the king of fruits, will be even more brilliant in the fruit juice fever. Healthy new fashion, starting with kiwi fruit juice.
