1, the harm to children's health
Children have poor ability to metabolize fat. If children often eat foods high in sugar, fat and oil, it is likely to lead to diseases such as hypertension, diabetes, gallstones and obesity. Obesity will aggravate precocious puberty and prematurely secrete estrogen or androgen, which will affect early production and development.
2. Harm to adults
Excessive intake of trans fatty acids will lead to obesity, fat will accumulate in the abdomen, and abdominal obesity will increase the risk of hypertension and diabetes; Trans fatty acids increased the risk of heart disease by 265,438+0% and the mortality by 28%. It can also aggravate inflammation and endothelial dysfunction.
1, fried dough sticks, oil cakes and other puffed fried foods.
In the process of refining and deodorizing, vegetable oils usually need to be heated at high temperature for a long time, which will produce a small amount of trans fatty acids. It has many names, some of which are hydrogenated vegetable oil, hydrogenated palm oil, hydrogenated fat, hydrogenated vegetable oil and so on. But in fact, they are all hydrogenated fats, so when you buy packaged food, if there is hydrogenated XXX in the ingredients, please be alert! Usually fried at 220℃ or repeatedly fried, especially in the kitchen of restaurants, fried dough sticks and fried cakes spread early and produce trans fatty acids, and the longer the heating time, the more trans fatty acids are produced.
2. Chocolate
Most chocolates on the market contain cocoa butter, which is an artificial edible oil used to make chocolate and cocoa powder, not cocoa butter. It is extracted from vegetable oil, so it also contains a lot of trans fatty acids. Due to the high refining cost and low melting point (about 34-38℃) of cocoa butter, it is not easy to store at room temperature, so some chocolate manufacturers will add some cocoa butter substitutes to reduce costs. It is suggested that when you buy chocolate and snacks containing chocolate, you must pay attention to whether the ingredients are cocoa butter or cocoa butter substitute. Wafer foods such as Nestle Crispy Sharks, which are common in supermarkets, all contain cocoa butter substitutes.
3. Snacks like cakes and biscuits
In some buttered popcorn, buttered biscuits and buttered cakes, you need to be wary of vegetable butter. Vegetable butter, also known as margarine or margarine, is cheaper than butter, but it tastes quite bad and tastes like rubber oil. In fact, vegetable butter itself is not a trans fatty acid, but it needs to be hydrogenated in the production process, and some hydrogenated fats will be converted into trans fats, especially vegetable butter produced by some small workshops with rough and backward technology. Everyone should pay attention to whether there are substances such as vegetable butter on the packaging of cakes, biscuits and other snacks, or be cautious.
4. Crispy bread
Shortening bread, such as croissants, raisin bread and chocolate buns, contains shortening, which is usually used to bake pasta to make food crisp. The ideal shortening should be semi-solid at room temperature. In order to save costs, most manufacturers will add hydrogenated oil, rapeseed oil and palm oil, and almost all of them contain trans fatty acids. These breads are especially high in fat, and usually 20%-30% butter or shortening is added, because this can form a special layered structure.
First: reduce the intake of trans fatty acids.
Everyone should reduce the intake of the above foods in their daily diet; Pay attention to raw materials and ingredients when purchasing food: check whether there are trans fats, trans fatty acids and trans fats in the food ingredients list, and pay attention to the words "hydrogenated, refined, artificial and crisp"; Avoid using hydrogenated oils, including vegetable butter, vegetable butter, cocoa butter substitute, creamer, margarine, etc.
The second thing: supplement selenium
Selenium is an important element to maintain the normal function of the heart, which can protect and repair the heart. The decrease of human blood selenium level will lead to the decrease of the function of scavenging free radicals in the body, which will lead to the increase of harmful substances deposition, the increase of blood pressure, the thickening of blood vessel wall, the decrease of blood vessel elasticity, the slow blood flow and the decrease of oxygen transport function, thus inducing the increase of the incidence of cardiovascular and cerebrovascular diseases. However, scientific selenium supplementation has a good effect on preventing cardiovascular and cerebrovascular diseases, hypertension and arteriosclerosis.
Generally speaking, the utilization rate of organic selenium is high, which can reach more than 70%. Artemisia argyi green tea is rich in natural organic selenium, and the selenium content per100g is 15ug, which is 5-6 times that of tea in other non-selenium-enriched areas. In addition, Artemisia argyi green tea is green tea made without fermentation, which retains the natural substances of fresh leaves: tea polyphenols, catechins, chlorophyll, caffeine, amino acids, vitamins and other nutrients, and has the functions of enhancing resistance, anti-aging and preventing cancer.
The third thing: homemade food
For the sake of health, it's best to make some self-made food, such as steamed bread, steamed stuffed bun and flower rolls, and occasionally make some low-sugar cakes. Don't exceed the total amount of fat in the whole day, drink skim milk, eat meat with peeled and visible fat, eat a balanced diet, eat a variety of foods, don't eat too much, and stay away from hydrogenated oil trans fatty acids. Health is in your own hands.
