nutritive value

The main components of plant fresh cream are plant fat (about 20%) and animal or plant protein with high nutritional value, while animal fresh cream (natural cream) is concentrated from milk fat extracted from fresh milk, and the main component is animal fat (accounting for more than 80%). Animal fresh cream contains high cholesterol and calorific value, and it is easy to get arteriosclerosis, heart disease, coronary heart disease, obesity and other diseases after long-term consumption. Therefore, the incidence of heart disease and arteriosclerosis is higher in European and American countries that eat more animal fresh cream. However, vegetable fat fresh cream contains no cholesterol, has low calorific value, and has high nutrition and health care functions. In fact, it was not until the end of 2005 that people discovered that trans fatty acids were more harmful. Because trans fatty acids not only increase "bad" cholesterol, that is, low-density lipoprotein, but also decrease "good" cholesterol, that is, high-density lipoprotein. Saturated fatty acids only increase "bad" cholesterol. The US Food and Drug Administration believes that trans fatty acids will increase people's risk of coronary heart disease. Therefore, they require that from June 5438+1 October12006, the content of trans fatty acids must be marked on food packaging, just like saturated fatty acids and cholesterol, unless the trans fatty acid content is less than 0.5g ..

Flavor and taste

Natural cream contains more than 80% animal fat, mainly saturated fatty acid, which has a high melting point and is not easy to melt, so natural cream is greasy and waxy. Animal fat also contains volatile fatty acids, which are easy to produce beef flavor when heated, seriously affecting the flavor of natural cream. Most vegetable fats contain unsaturated fatty acids, and their melting point is low, which is close to the oral temperature, while the vegetable fat content of vegetable fat cream is low, so the better vegetable fat cream melts in the mouth, and the cake made is particularly light and refreshing, sweet but not greasy. And vegetable fat doesn't taste like beef. Hydrogenation can prolong the shelf life of food and keep the taste of food stable. But from a health point of view, it is not safe.

food safety

Natural cream is a refined product, part of which is made by fermentation, with complex components and poor safety. Not as good as vegetable butter, it is completely refined oil, with clear ingredients and safe to eat (extending shelf life). This is not the case, but now people have discovered its harm.

value

Trans fat is cheaper than natural butter, but its effect is not inferior to natural butter: its solid form can make various shapes of western pastry, and it can also extend the shelf life and increase the palatability of food. However, the harm of trans fat to human health has long been proved, and its health is far less than that of natural butter!

Edit this section of danger

"Vegetable cream" is as famous as pesticide. The health killer under delicious food should be carefully eaten. Scientists have found that hydrogenated oil, because it is "fake oil", cannot be decomposed by the body and cannot be metabolized. Finally, it can only stay in the body and accumulate on the walls of cells or blood vessels, which may cause kidney calculi and other hazards. The harm of hydrogenated oil to health is manifested in four aspects: increasing blood viscosity and cohesion and promoting thrombosis; 2. Improve low-density lipoprotein cholesterol (bad cholesterol), reduce high-density lipoprotein cholesterol (good cholesterol), and promote arteriosclerosis; 3. Increase the incidence of type 2 diabetes; 4. It affects the normal growth and development of infants and adolescents, and may have a negative impact on the development of the central nervous system. Generally, fat is metabolized in 7 days, while trans fat can be metabolized in 50 days, which is also the reason why foreign fast food can lead to obesity. Eating trans fats will increase the risk of coronary heart disease, because it can increase "bad" low-density lipoprotein cholesterol and decrease "good" high-density lipoprotein cholesterol. Studies have shown that diets with high trans fat content are related to heart disease, arterial disease and arteriosclerosis. Studies have shown that if you consume 5 grams of trans fat every day, your risk of heart disease will increase by 25%. Studies have shown that if children eat a lot of foods containing trans fatty acids for a long time, it will interfere with the necessary fatty acid metabolism, adversely affect their growth and development, and increase the risk of breast cancer in women. What are the specific health hazards for many people who like to eat food such as cream cakes since childhood? At present, there is no relevant report and proof.

Edit this assessment.

Moderate illness [1]? Zhang Jian, a researcher at the Institute of Food and Nutrition Control, said that the preliminary monitoring results showed that the per capita intake of trans fatty acids of Chinese residents was about 0.6 grams, far below the level of European and American countries. Researcher Zhang used the per capita intake of trans fatty acids of China residents to evaluate the harm of "vegetable butter". Judging from the actual situation of China's national conditions and tastes, I'm afraid this is unscientific and imprecise. The Institute of Nutrition and Food of Chinese Center for Disease Control began to monitor trans fatty acids in food in 2003. The per capita intake of trans fatty acids in China is about 0.6 grams, which should be accurate. However, China has a large population. According to the main added food category of "plant cream", the intake of "plant cream" by hundreds of millions of people in rural areas is definitely much lower than that of urban population, and the intake of young children in urban population should be higher than that of other age groups. For people who especially like related foods, they should be the biggest victims, but their intake is "average". Therefore, the per capita intake of trans fatty acids does not reflect the specific harm to the human body. In other words, the data of per capita intake is meaningless to individuals. What ordinary people need to know is whether "vegetable cream" can be eaten, how much it is harmless to the body, and how the state controls the addition of vegetable cream. Unfortunately, the answer given by researcher Zhang is very simple, only saying that "China can't eat cream food" is wrong. In fact, rational people know that "China cream food can't be eaten" is just an exaggeration, but when experts can't point out which one can be eaten and how to eat it, they can only explain that the statement is wrong, and I'm afraid everyone still dares not eat it.

Edit the difference between this paragraph and animal cream

Type: basically divided into animal cream and vegetable fat cream. Animal cream is obtained by separating fat from milk. Vegetable cream is made of vegetable oil such as soybean, water, salt and milk powder. Taste: In terms of taste, animal cream tastes better. Vegetable butter is the kind that we can usually buy in cake shops. The calorie is less than half of that of ordinary animal cream, the saturated fatty acid is less, and there is no cholesterol. Butter, which is commonly used in making West Point, still needs block butter. For example, many people bought delicious boxes and used them in failure. They want to buy delicious chunks of butter.

Thoughts on food safety when editing this paragraph

Hydrogenated oil, also known as vegetable butter, vegetable butter and non-dairy creamer. This product, which comes from the so-called safe food game rules in the west, has recently been accused of being the chief culprit of the diabetes epidemic. Mr. Nie Wentao, a diabetes doctor, recently published his views [2]. The edible history of 1 and 60 years can be traced back to 1950s. In the past 60 years, it has been widely used in baking food ingredients, cold food ingredients, candy ingredients and solid beverage ingredients. In 2003, Denmark took the lead in prohibiting any oil containing trans fatty acids (the main harmful component of non-dairy powder) in the market, and then the United States, Canada, the Netherlands, France and Sweden also made relevant regulations. Since July 2008, all catering industries in new york have completely banned foods containing trans fatty acids. 2. Reflection on food safety Those so-called safe foods that can be quantitatively detected are actually synthetic foods with too pure ingredients. However, natural foods with unstable ingredients and difficult detection are often accused of being unable to guarantee their safety. Facts show that the actual result is just the opposite. The principles demonstrated by countless experts in western countries, as well as the promotion of western politicians and legal professionals, have formulated many shocking safety standards. Everything that can form an assembly line has been proved to be safe. Under such standards, mankind is paying a huge price. 3. Is the harm of hydrogenated oil amazing? The harm of these artificial non-dairy creamers is obviously not as great as the legend. So it can exist for a long time. In China, for example, people still mainly use natural food while using such products. Occasionally use, a small amount of use, the harm to the human body is not great. It is also incorrect to completely deny the western food safety evaluation system. 4. Have you found the culprit of diabetes? In fact, the foods that we screened out according to western nutrition standards, such as meat, eggs, milk and other high-nutrient foods recommended by a large number of people, are important dietary incentives for obesity, hyperglycemia, hyperlipidemia and high uric acid. It is naive to think that banning non-dairy creamer will cut off the root cause of diabetes. The traditional diet structure of the Chinese nation has adapted to the long-term evolution of mankind. According to Darwin's theory, the change of food structure will lead to a large number of individuals unable to adapt and being eliminated. Nie Wentao pointed out that respecting human tradition means respecting people themselves. World Diabetes Day is coming again, and I don't want to see too many business lies.

Edit this paragraph of the national regulations

Denmark

In 2003, it was the first time that any oil with trans fatty acid content exceeding 2% was prohibited. This content is extremely low, which means it is basically unusable.

United States of America

In the same year, the regulations issued by the US Food and Drug Administration (FDA) pointed out that from June 5438+1 October 1 in 2006, the content of trans fatty acids must be indicated in food nutrition labels, unless the content of trans fatty acids is less than 0.5g From July1day in 2008, all restaurants in new york are completely prohibited from containing trans fatty acids. The New York Times said that the federal food guide issued by the US government last year reminded people that the daily intake of trans fatty acids should be less than 2 grams, while the US government research institutions and medical research institutes believed that the safe intake of trans fatty acids should be zero.

Canada, Brazil

It is required that foods with trans fatty acid content exceeding 0.5g must indicate the trans fatty acid content in the label. Canada established the trans fatty acid task force in 2004.

Korean, Singaporean, China and Taiwan Province provinces.

All food packages should be marked with trans fat content.

Holland, France, Sweden, Germany and other countries.

It is required that the content of trans fatty acids in food must be controlled below 5%; In China, there are no restrictions on "vegetable cream". "Vegetable butter" has also been used unscrupulously. In recent years, the high incidence of diabetes and cardiovascular diseases in China is also related to people's daily consumption of food containing "vegetable butter". Scientists compare "vegetable cream" with pesticides, which shows its great harm! Experts suggest that the daily intake of trans fatty acids by adults should not be higher than110 of an 8-inch cake. For the sake of long-term health, people should try to avoid eating too much food containing hydrogenated oil when choosing food, and don't excessively pursue soft and crisp taste.

A survey of editorial reporters

CCTV Economy reported "hydrogenated oil" for half an hour, or the biggest disaster in the history of brewing food, focusing on vegetable cream. (we are "trans”~ ~ ~! ! ! 20 10-02-23) 12-30, the reporter saw in Wal-Mart wanda plaza store that most of the grease on the label of Master Kong biscuits was "refined vegetable oil (partially hydrogenated palm oil and coconut oil)", such as 3+2 soda sandwich (coffee milk flavor), sweet and crisp sandwich (hazelnut chocolate flavor) and salty and crisp sandwich (alcohol). And Haoliyou mushroom chocolate (chocolate flavor) uses "hydrogenated vegetable oil and shortening"; "Edible vegetable oil (partially hydrogenated) and margarine" are used as milk-flavored decorative biscuits for Glico bagels; Kraft Youguan yogurt sandwich cookies and Oreo chocolate sandwich cookies use "edible vegetable oil and edible partially hydrogenated vegetable oil", and Lotte of BearBiscuit uses "vegetable oil and shortening"; The sandwich pastry bag with the flavor of Bembourg Doffie egg milk is "margarine" and Bimbo Stichopus is "margarine". On February 29th, 65438, the reporter saw in Carrefour International Exhibition Store that Master Kong's fragrant chocolate cookies used "partially hydrogenated palm oil and hydrogenated vegetable oil", Fu Miao cake used "refined vegetable oil (partially hydrogenated soybean oil and partially hydrogenated palm oil)", Haoliyou Panda brand used "edible vegetable oil, hydrogenated vegetable oil and shortening", and Haoliyou Q Di hazelnut chocolate cake used shortening. If it is understandable that cookies use trans fats because they need to be preserved for a long time, it is a bit unreasonable that Wedome and Wal-Mart's fresh West Point are also full of trans fats. At noon on February 29th, 65438, the reporter saw in Wedome Jing 'anli Store that many products in the store used "vegetable oil (partially hydrogenated)", such as transparent canned coconut ball West Point, mosaic biscuit and bean paste roll West Point. In addition, the price of a 320g "cheese golden brick bread" is as high as that of 22 yuan. Although the composition of cheese is the reason for its high price, the oil used is actually "vegetable oil (partially hydrogenated)" instead of natural butter, and the imperial concubine burrito in 5.5 yuan uses "refined vegetable oil", and the shelf life of the above products is about 4 days. In Wal-Mart, only a few western-style cakes use "butter", such as whole wheat strips, walnut snack bags, golden wheel bags, long meat floss bags and honey bean meal bags. The reporter saw that 10 inch cakes and cupcakes all use "vegetable fat cream", while 4 inch birthday cakes and Swiss rolls all use "vegetable fat cream and salad oil". The shelf life of the above products. Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety of China Agricultural University, pointed out that the use of fresh butter is usually advocated for fresh western pastry which is sold now and has a short shelf life, because trans fats are not needed to extend the shelf life. Many well-known foreign handmade pastry houses insist on using fresh butter, but manufacturers sometimes use trans fats for cost reasons.

Palm oil in snack food: worse than lard

The fats and oils used in snacks are the hardest hit areas of trans fats. 654381On the evening of October 2, the reporter came to Jingkelong Tuanjiehu Store and conducted a random survey on snack foods including chocolate, coffee, candy, potato chips and instant noodles. The results show that palm oil has become the most popular oil for many potato chips, rice cakes and puffed foods. Experts told reporters that the nutritional quality of palm oil is worse than that of lard. For example, Nestle Coffee 38 (13g) and Maxwell original flavor 12 instant coffee drinks all contain edible hydrogenated vegetable oil, while Cadbury original Yikoulian 34.2g and Cadbury coffee milk chocolate toffee 200g also use hydrogenated vegetable oil (instead of cocoa butter), which is the embodiment of trans fat. Ferrero imported 300g hazelnut wafer chocolate, which has relatively healthy oil and is "anhydrous cream vegetable oil". Di Chin's 105g delicious hazelnut chocolate, Di Chin's 160g nut chocolate eggs are "edible refined vegetable oil and anhydrous cream", and Dove's 90g smooth milk chocolate is "refined edible vegetable oil". Experts pointed out that there are many kinds of refined vegetable oils, including partially hydrogenated vegetable oils, so they are not necessarily healthy oils.

palm oil

Become the only oil for many potato chips, rice cakes and puffed foods. Subsequently, the reporter found that, for example, Xu Fuji's 560 grams of egg Shaqima, Sun Crisp 130 grams of spicy taste, 52 grams of Wangwang fresh shellfish, and Wangwang rice cake 135 grams, as well as the best 55 grams of pastoral potato chips and tomato flavor, the best crispy peanuts and the best Dutch beans all used "palm oil". He said that palm oil is not a healthy oil. Palm oil with melting point of 24℃ is generally used for fried biscuits, instant noodles and other non-staple foods. Palm oil with melting point of 12℃ and below has certain nutritional value, but palm oil with melting point of 24℃ is generally on the market at present, which is not suitable for long-term household use, because the content of saturated fatty acids in palm oil is above 50% and its nutritional quality is worse than that of lard. Long-term consumption of palm oil will cause excessive intake of saturated fatty acids in human serum. A variety of instant noodles, such as Master Kong's tomato gravy noodles and unified breakfast instant auricularia chicken soup noodles, all use refined palm oil, while Master Kong's noodles are mainly spicy beef from Lamian Noodles, and Master Kong's spicy beef noodles are richer in oil, which is "refined palm oil (including vitamin E), sesame oil and refined butter". The reporter also found that the taste of 45g strawberries in Shanghaojia millet strips actually used "fully hydrogenated palm kernel oil". Experts pointed out that palm kernel oil is more saturated and fully hydrogenated, and many kinds of Xerox potato chips and Haoliyou potato chips are made of vegetable oil, while Haoliyou friend Fun also has crispy potato chips with camellia oil as the selling point, which is to make a fuss about the health of oil.

Oil labeling is not standardized: you didn't discuss it.

Consumers with relevant knowledge can also choose whether to buy the clearly marked oil components, but many West Point do not indicate what oil is used at all, so consumers may only "guess". The reporter found that the oil used in transparent canned Melaleuca pie, sesame crisp, plastic bag sliced bread, German milkshake bread and Danish strawberry bread only says "oil", which makes people feel very vague. He pointed out that many products use unhealthy oils such as hydrogenated vegetable oil, which may discourage many consumers, but respect consumers' right to know. On the afternoon of February 29th, 65438, at the counter of the Bread Department of Carrefour International Exhibition Store, the reporter also saw that the ingredients of Carrefour 3.8 yuan Coconut Bread only wrote "eggs, fresh milk and sugar", but the added coconut shreds were large and the oil used was not marked. Moreover, the ingredient list of more than half of Carrefour's homemade western pastry is unified as "flour, sugar, butter and salt", such as three slices of whole wheat toast, Danish grape rolls and so on. On the afternoon of February 30, 65438, the reporter saw at Wal-Mart's self-made West Point counter that 3.5 yuan's applesauce ring ingredients were "bread flour, milk powder, eggs, etc." The bread ingredients of 6.5 yuan's floss cake are "bread flour, salt, milk powder, floss, etc." . In addition, many ingredients in West Point, such as Danish steamed buns, American raisin steamed buns, raisin wheat steamed buns, pineapple steamed buns, bean paste whirlwind steamed buns, coconut steamed buns and red bean square steamed buns, are also fat-free. Professionals pointed out that only from the name point of view, most of the above products can not use any oil, so the component labeling is incomplete. Therefore, some merchants simply changed the name of oil and used some terms that even experts could not understand. On February 29th, 65438, the reporter saw in Holiland Zuojiazhuang Store that the bread in Swan Castle was made of "sweet cream", while the low-sugar carrot meal package, low-sugar miscellaneous grains meal package and orange chocolate cake were all marked with "big butter" that people could not understand. Carrefour's cheese sandwich, Wal-Mart's French vegetable bread in 4.9 yuan all use "yellow cream", Wal-Mart's four old ladies' cake in 8 yuan uses raw oil, and Wal-Mart's onion and ham toast in 3.9 yuan uses "white oil" that can't be understood. The reporter asked Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety of China Agricultural University. She guessed that "big butter" and "yellow cream" might be butter, and "raw oil" might be lard. "White oil" may be shortened, because these words are extremely irregular, and it is really difficult to explain what oil is, and many businesses just don't want consumers to know what it is, so they use some irregular terms to confuse the audience. In addition, half of Wal-Mart's jujube paste walnut cakes in 6.9 yuan use "cake oil and vegetable oil", while the banana cakes in 4.9 yuan use "cake oil and salad oil" and face "cake oil and cake oil". Some consumers also think it is a better special oil of unknown so. Fan Zhihong introduced that cake oil is just a kind of food additive that makes cakes beautiful, exquisite and cheap, and its main component is chemicals.

Edit this paragraph of trans fat-hint

First, not all oily things contain trans fats. Trans fats mainly come from three sources: 1. Vegetable oil is solidified from liquid oil. 2. In the process of high temperature heating, light, heat and catalyst can isomerize vegetable oil fat into trans fat. 3. In nature, it is produced in the stomachs of ruminants such as cattle, such as milk and beef, and contains a small amount of trans fat. So there is no trans fat in unheated vegetable oil. 2. Oil without trans fat will also produce trans fat after heating. When cooking at high temperature or for a long time, the more fats (such as soybean oil and safflower oil) rich in monounsaturated or polyunsaturated fatty acids, the easier it is to produce trans fats-because unsaturated fatty acids are "active" and easy to be oxidized. These oils are suitable for cold salad, stew or quick cooking, and there is no smoke. Cooking at home, just burn the oil for seven minutes, don't wait for smoke to cook. When frying food, you can consider using oils with high saturation such as lard and palm oil. In addition, repeated heating of oil will produce more trans fats, so the fried oil cannot be reused and should be thrown away. Third, if you eat properly, you can completely avoid taking trans fatty acids, because there are very few trans fats in natural foods. Trans fats in dairy products and beef and mutton only account for 0.0% of their fat content, which is less than the level of eating more than 2 grams a day under normal circumstances. If cooking with oil is low temperature and short time, the trans fat produced is also very small, which can be basically ignored. A person living a healthy life, using fresh fat, seldom frying at high temperature, eating more cold stew, cooking fresh meals at home and not eating all kinds of processed foods, can stay away from trans fats. Tip: Use some heart-healthy oil. These oils are edible oils containing monovalent or multivalent unsaturated fatty acids, such as olive oil, rapeseed oil or soybean oil. In addition, don't eat too many snacks, biscuits, bread, cakes, French fries, doughnuts and other fried foods.
