Sugar exceeds the standard!

Trans fat exceeds the standard! ! ! !
Sugar+fat makes people fat.
Caffeine makes people excited every day.
Can trans fat make people have cardiovascular and cerebrovascular diseases? go to hell
I believe that in addition to the well-known ingredients such as sugar, fat and caffeine,
Most people are still in the dark about trans fats.
Sweet killer: trans fatty acids
Trans fatty acids? Many people look at a loss after listening. In the past, edible oils and fats were mainly animal oils and fats, such as butter, cream and lard, which were scarce and expensive. Vegetable oil is cheap, but the fatty acids of edible vegetable oil are basically cis fatty acids, which are unstable, liquid and easy to deteriorate. Thus, trans fatty acids came into being. After hydrogenation, vegetable oil becomes semi-solid, which is stable and not easy to deteriorate, and can prolong the shelf life. Moreover, the cost is lower than that of animal fat such as natural cream, but it contains a lot of trans fatty acids. In the past, the intake of trans fats from the diet was very small. In recent years, with the increase of artificial fat, trans fat intake from diet has also increased.
Trans fatty acids: permeating our lives
In mobilizing taste buds, trans fatty acids are really extraordinary, and processed foods containing artificial trans fatty acids can be seen almost everywhere. In the fried food in the restaurant. It can be found in fried chicken, French fries, potato chips, instant noodles, twists and so on. Among fried foods, cakes, cakes, biscuits, bread, biscuits, egg yolk pie, chocolate, ice cream, milk tea, coffee, salad dressing, etc. In baked goods.
As we all know, unsaturated fatty acids are beneficial to human body (but these are more "cis" fatty acids). Cis fatty acids need only 1 week to metabolize in human body, while trans fatty acids need 7-8 weeks. The time span is amazing! So people who love fast food and dessert are more likely to be obese! At the same time, another particularity of trans fatty acids is that it can reduce high-density lipoprotein and increase low-density lipoprotein in blood, which increases the incidence of hyperlipidemia to some extent.
Is there a problem with the intake level of China people at present?
In order to avoid the risk caused by excessive intake of trans fatty acids, the World Health Organization (WHO) suggested in 2003 that the energy supply ratio of trans fatty acids should be lower than 1%. (Note: the energy supply ratio of trans fatty acids refers to the percentage of energy provided by trans fatty acids in total dietary energy intake)
According to the assessment results of the National Food Safety Risk Assessment Center, the energy supply ratio of trans fatty acids for residents in big cities like Beijing and Guangzhou is only 0.34%, which is far lower than that of WHO (
See trans fatty acids through label ingredient list and nutrition label?
The common expressions of hydrogenated oils and fats in the label ingredient list are as follows: hydrogenated vegetable oil, partially hydrogenated vegetable oil, hydrogenated palm oil, hydrogenated soybean oil, vegetable shortening, margarine and so on. Therefore, when buying packaged food, consumers should pay more attention to the nutritional ingredient list on the label if the ingredients list contains the above ingredients, and can choose foods that do not contain trans fatty acids or have low trans fatty acids content.
The General Principles of Nutrition Labeling in prepackaged foods, which was implemented on June 65, 438+03 +438+01October 65, stipulates that if hydrogenated and/or partially hydrogenated fats and oils are contained in food raw materials, the trans fatty acid content must be indicated in the nutrition composition table of food labels. Similarly, the standard also stipulates that 100 grams of food with less than 0.3 grams of trans fatty acids can be marked as "0".
Trans fatty acids are very harmful to health.
Related studies have found that in the investigation of the correlation between the types of fats and the incidence of cardiovascular diseases, trans fats are "dominant" and "stand out from the crowd"-the greater the intake of trans fatty acids, the higher the incidence of cardiovascular and cerebrovascular diseases. It increases the risk of cardiovascular disease, which is higher than saturated fatty acids in animal fat. At the same time, trans fatty acids can increase LDL-C and decrease HDL-C in plasma, which is easy to induce atherosclerosis and increase the risk of cardiovascular diseases. The risk of coronary heart disease and hypertension, and research shows that it will increase the risk of cancer and diabetes.
