Purple potato can defend cancer and cardiovascular disease
Summary: In recent years, domestic and foreign research show, sweet potato have remove free radical to be anti-oxidant antitumor preventing and treating the intersection of cardiovascular vessel and disease, restraining fungus many kinds of medical functions. Where does this kind of research come from?
In recent years, the agricultural products of a lot of innovation in pattern or design have appeared on people's dining table, such as purple sweet potato. It is said, this kind of sweet potato removes the function such as being anti-oxidant, antitumor of free radical, is the fact really so? Please pay close attention to - -
1990s, one skin getting purplish black succeed in introducing of our country the intersection of sweet potato and researcher from the intersection of aquatic products and the intersection of province and agricultural proving ground of Kyushu, agriculture and forestry of Japan, to our country by the intersection of meat and getting mauve the intersection of sweet potato and new variety potato, later there were new names - -" purple core sweet potato " Or " purple sweet potato " .
The expert points out, purple sweet potato is different from the general sweet potato variety, it contain many kinds of nutrient components such as very abundant cyanine plain type pigment, many candy, plant albumen, vitamin, ore element, and become at present for a time agricultural products research and develop the focus that personnel research and develop.
What is purple sweet potato on earth the thing? Why is it pursued by everybody? Nowadays, the price of purple sweet potato is much higher than the fruit price of other vegetables on the market, may it move towards ordinary masses' dining table?
Why can purple sweet potato cure the disease
In recent years, domestic and foreign research show, sweet potato have remove free radical to be anti-oxidant antitumor preventing and treating the intersection of cardiovascular vessel and disease, restraining fungus many kinds of medical functions. Where does this kind of research come from?
Southwest university student order scientific the intersection of institute and the intersection of Chongqing and the intersection of city and the intersection of sweet potato and the intersection of research center and Wen TaoYong, Liu light to go on relevant research jointly while being better, they point out, there may two kinds of purple resisting oxygen routes in animal's body of pigment of sweet potato: First, remove too many free radicals by improving animal's indirectness against oxidase activity and is applied; Second, the purple design glucoside molecule of sweet potato has a phenol hydrocarbon base, phenol hydrocarbon base is apt to reduce and release the electron through oxidizing, supply free radical, and remove all kinds of free radicals directly.
It is reported, the purple root tuber of sweet potato because contains a large number of cyanine pigment in the body to presents bright-colored mauve, the purple plain molecular structure of cyanine of sweet potato, because of having a plurality of phenol hydrocarbon base, therefore is a kind of water soluble pigment. Compared with glucoside pigment of other designs, getting purple the intersection of sweet potato and the intersection of design and the intersection of glucoside and heat resistance and it able to bear alls to be best. The properties of the purple pigment of sweet potato are important for abstraction of the purple pigment of sweet potato and its physiological activity of full play.
Besides containing the abundant design glucoside pigment, sweet potato contain quite abundant the intersection of plant and the intersection of albumen, free amino acid, large candy, vitamin, ore quality ion,etc. and other important nutrient components essential for human body also. Analyze according to the Japanese agricultural product monitoring center: Black sweet potato (the purple mountain of Sichuan of sweet potato variety in Japan is purple) The content of 2,6-diaminocaproic acid, copper, manganese, potassium, zinc of China is 3-5 times that of ordinary sweet potato, especially the content of iodine and selenium is more than 20 times of the ordinary variety. Analyze according to the American agricultural product monitoring center: U.S.A. " black sweet potato " The nutritive value of the new variety is obviously higher than other potatoes, the content of its 2,6-diaminocaproic acid, potassium, manganese, zinc is higher than general sweet potato by 5- 8 times, especially against material iodine of cancer, selenium the content 20 times higher the above than other sweet potatoes, primary importance food.
The purple remaining amount of sweet potato is produced
Just because purple sweet potato is nutritious and having medical value, in addition, purple sweet potato of our country is not tall in output at present, so the purple price on the market of sweet potato is still very expensive, some are even sold for 18 yuan each kilogram. Obviously, such a price can be afforded by ordinary people. Then, can the price of purple sweet potato be lowered, come into ordinary dining tables of masses as soon as possible?
TaoYong Wen explain because generally getting purple the intersection of sweet potato and the intersection of design and the intersection of glucoside and content and fresh potato and potato be output exist and shoulder relevantly, "pass finding though design the intersection of glucoside and the intersection of content and high variety fresh potato low in output often, but may breed the producing amount and high high-quality variety of pigment content. "
It is reported at present, our country getting purple the intersection of sweet potato and seed selection work, begin just. Will it be March 2003, national the intersection of sweet potato and person who try on the intersection of Chongqing and the intersection of city and meeting make getting purple at home for the first time the intersection of seed selection and goal and pigment content of sweet potato determine the method, and an important goal of seed selection is the contradiction overcome among content of nutrient component and fresh potato output such as pigment.
Liu XiaoQiang introduces, at present, it is developed countries such as Japan,etc. to study in purple sweet potato and pigment and utilize the respect to walk in forefront, the purple sweet potatoes of these countries have already become a kind of indispensable health food in national daily life, planting and the market development respect is being done better than our country.
"As a good merchantable brand with abundant nutrient component and medical value, purple sweet potato will have a very broad development prospect. " Wen Tao's brave suggestion, for example can develop and have high wine of sweet potato of purple which resists the oxidizability, various beverages with characteristic of flavor, the bright in colour nonpoisonous food condiment,etc..
The healthy diet is due to sweet potato
Getting purple sweet potato, because of the intersection of research and development and achievement of new technology, therefore nutrient component take high relatively. But as the ordinary sweet potato variety, its nutritive value can't be ignored either.
Professional committee Deputy Director, agronomy of China Agricultural University and biotechnology institute's Vice President Professor Liu QingChang express Chinese sweet potato, sweet potato (sweet potato that commonly called as) It had not already been said in the past " The coarse food grain " , " paste grain ration providing disaster relief " ,But nutrition is very abundant, complete, and have important food that kept healthy and prevented and cured the disease function. "Except containing a large number of starch, soluble candy, many kinds of vitamin and many kinds of amino acids in the root tuber of sweet potato, also contain minerals such as protein, fat, food fiber and calcium, iron,etc., the nutritive value is not second to the rice, surface. Food sweet potato suck fibrous texture fine and smooth, injure stomach, to prevent disease and maintain healthy to have important functions, it is the fibrous source of food that the medical nutritionist praises highly. "
It is introduced Japan state-run cancer prevent research institute, carry on the census to 260,000 the intersection of diet and life and relation of cancer of people once, prove the vegetables have certain anti-cancer function. And restrain the test result of cancer through the analysis against cancer composition to 40 multi-type vegetables, from high to being low to discharge, have on tumour, it inhibits vegetables of effect notably to be by 20: Well done sweet potato, raw sweet potato, asparagus, cauliflower, cabbage, cauliflower, celery, eggplant peel, sweet pepper, carrot,etc..
In fact, have had records about sweet potato in our country for a long time too in ancient times. Li Shizhen has recorded on " Compendium of Materia Medica ", sweet potato has " tonifies deficiency exhaustedly, benefit strength ", good for the spleen and stomach, the strong kidney is overcast, grow muscles, the cosmetic face " Efficiency,even more " steam sweet potato, cut, shine, harvest ",can't use by grain as, last people longevity diseases less " Saying.
As the nutritious alkaline food of physiology, the expert proposes, in era when life is rich, sweet potato cooperates with coarse food grain, egg, milk, meat,etc. to be eaten together, favorable to good health and a long life of body.
" the stomach is empty, all things are all empty " ,This sentence says the importance of the diet, with the constant improvement of life quality, eat, feed oneself so getting simple, eat anything, how it wipes out to be what people care.The diet wanting science to be rational please enter:Diet channel
