China's disease accuses of centre's explaining the trans-fatty acid in detail and to healthy influence
Special despatch of November 20 of www.xinhuanet.com Beijing It causes the social extensive concern that recent relevant trans-fatty acid endanger the topic of the health. For this reason, Center for Disease Prevention and Control of China has introduced the relevant science knowledge of the trans-fatty acid, in order to answer public doubt, advocate resident's healthy diet. It is introduced, begin from the human edible oil, there is existence of trans-fatty acid. Because the microorganism in ruminant's body will produce the natural trans-fatty acid of small quantity, when people are edible food such as beef and mutton, milk, will take in the natural trans-fatty acid of small quantity. In the seventies and eighties of last century, in order to meet the needs of special preparation method, western industrial countries hydrogenated the vegetable oil one after another, in this course, the unsaturated pair of keys of some oil can happen differently and construct to melt, produce the trans-fatty acid. The content of trans-fatty acid that different vegetable oil produces after hydrogenating differs greatly. Because oil after the hydrogenation have melting point to be high oxidizing the intersection of stability and fine, the intersection of shelve and issues of long, the intersection of flavor and uniqueness, the intersection of mouthfeel and advantage such as being good, and occupy the advantage even more on the cost, this craft is used extensively by the western industrial country in last century, put on market in products forms such as the margarine, the butter arises, frying and pressing oil,etc., thus lead to the fact that exists in food such as some cake, biscuit, fried food in the western countries of trans-fatty acid extensively. China disease accuse of centre point out have research show, eat, hydrogenate trans-fatty acid produced to process, cause human fat of blood metabolic disorder while being excessive while being long-term, increase lipoprotein cholesterol (L D L - C) of low density Content, reduce cholesterol (H D L - C) of high density lipoprotein Content, the risk takes place to thus increase cardiovascular vessel disease. Some reports reveal, the trans-fatty acid is excessive for a long time to take in the chronic disease risk of may increase diabetes, fat ing etc.. China's disease accuses of centre's pointing out, as to the natural trans-fatty acid in the food at the same time, there are not materials that prove it to healthy adverse effect yet. Some research reveals, the natural trans-fatty acid may benefit the health. It is reported, domestic and foreign to have corresponding control measures to trans-fatty acid. Our government has been advocating healthy life style and balanced meal actively, in order to reduce the absorption of total fat and trans-fatty acid. " Chinese resident's meal guide " that Ministry of Public Health releases in 2007 proposes, the edible oil does not exceed 25 grams per person per day; The intaking amount of the total fat should be less than every day 30 that total energy took in, advise the residents of our country to be " far away from trans-fatty acid at the same time, eat little rich food containing oil of hydrogenation as much as possible " . World Health Organization proposes, healthy as promoting the cardiovascular vessel, should try hard to control the trans-fatty acid in the meal, maximum absorbing amount 1 which does not exceed total energy. That is to say, if adult and per capita according to one takes in 2000 kilocalories of energy to calculate every day, every day should not exceed 2 to take in the trans-fatty acid . 2 grams. In addition, some countries also take the way to label the trans-fatty acid on the food label by force to manage the trans-fatty acid, for example U.S. Food Drug Administration requires that labelled the trans-fatty acid in the processed food by force since January of 2006. Accuse of the central introduction according to China's disease, the literature report reveals, the trans-fatty acid of the western countries is relatively tall in intaking amount. The intaking amount of adult average daily trans-fatty acid is 5 in U.S.A. 20. 8 grams, account for 2 of total energy. 6 % ; The investigations of 14 countries of European Union reveal, the male trans-fatty acid average daily intaking amount is 1. From 2 grams to 6 . 7 grams, women are 1. From 7 grams to 4 . 1 gram, departure is equivalent to 0 of the total energy. From 5 to 2. 1 (men) With 0. From 8 to 1. 9 (women) . Our country have, study the report, reveal, the trans-fatty acid quantity which the urbanite takes in every day is about 1 gram on average, only accounts for 0 of total energy . About 5, the residents less than western countries take in the suggestion controlling value of competence and World Health Organization.
