Foreign fast food has high anti-fatty acid content and excessive consumption is harmful to the health
The Center for Science in the Public Interest stated in the complaint that some KFC foods are cooked with partially hydrogenated cooking oils and have "surprisingly high" anti-fatty acid content, which will put consumers 'health at great risks. This incident once again attracted people's attention to the food safety issues of "foreign fast food".
When people eat French fries, they find that the paper they wrap is never oily. Why? Because it hydrosaturates vegetable oil into so-called hydrogenated oil, hydrogenated oil has 38% trans fatty acids, which does not exist in nature. After more than ten years of research, it has been found that anti-eating oil can interfere with human endocrine. In order to prevent liquid vegetable oil from deteriorating, facilitate preservation and improve taste, food manufacturers use a hydrogenation process to turn it into solid or semi-solid oils. Anti-fatty acids are produced in the above process. Compared with ordinary vegetable oils, foods cooked with edible oils containing trans fatty acids are particularly crispy and delicious. Therefore, French fries, fried chicken nuggets, and salad dressings are all high in trans fatty acids. However, studies have shown that trans fatty acids are more harmful to human health than saturated fatty acids.
Excessive doses can cause heart disease
Frequent consumption of foods with high anti-fatty acid content can lead to cardiovascular diseases such as arterial blockages. People usually tell about their cholesterol levels during physical examinations, including high-density lipoprotein HDL and low-density lipoprotein LDL. An increase in low-density lipoprotein can cause vascular disease, known as "bad cholesterol." Studies have shown that saturated fatty acids increase the "bad cholesterol" content of LDL low-density lipoprotein in the human body, while anti-fatty acids increase the "bad cholesterol" content, but also reduce the "good cholesterol" content of HDL high-density lipoprotein in the human body. Data show that if the amount of trans fatty acids exceeds 6% of the total calories, the degree of blood coagulation will be significantly higher than that of those who consume 2%. The increase in blood viscosity can cause cardiovascular and cerebrovascular diseases such as cerebral thrombosis and arteriosclerosis. Therefore, experts in the medical community recommend that consumers try not to eat foods containing trans fatty acids. Dutch research shows that a two-percentage point increase in anti-fatty acids increases the risk of cardiovascular disease by 25%.
Affects fetal intellectual development
It is understood that pregnant women who consume more trans fatty acids can pass them on to the fetus through the placenta, and the nursing mother can pass them on to the baby through milk, causing a lack of essential fatty acids in the fetus and the baby, which affects growth and development. It can also cause brain lipid deficiency, affecting their intellectual development. In addition, excessive intake of anti-fatty acids may also trigger type 2 diabetes products in women. Diabetes information can reduce male hormone secretion, have a negative impact on sperm, and may also cause Alzheimer's disease.
The content of many common foods is unknown
According to Mr. Liang Chengqiang, director of the Nutrition Department of Zhongshan Hospital, all margarines contain trans fatty acids. He said that not only French fries contain trans fatty acids. Hydrogenated oils such as margarine, margarine, soybean oil, salad oil, and butter all contain high trans fatty acids. Under normal circumstances, the content of solidified oil is higher than that of liquid oil, generally between 5% and 45%, and the maximum content of margarine can reach 65%.
The reporter's investigation found that in the food processing process, margarine is only a raw material. Western-style cakes such as cream cakes, chocolates, salad dressings, fried fast food products and other foods processed with it all contain anti-fatty acids. However, the content of trans fatty acids is not marked on the packaging of such products sold in shopping malls and supermarkets. According to experts, in fact, products labeled with different names such as margarine cream, margarine cream, artificial fat, margarine, hydrogenated oil, shortening, etc. all contain anti-fatty acids. Instant noodles, soda biscuits, and egg rolls all have high trans fatty acid content. According to expert recommendations, the daily intake of trans fatty acids should not exceed 1%. How do I know if my intake exceeds 1%? This requires knowing the content of trans fatty acids in
