▲ Linoleic acid: It can accelerate the metabolism of skin cells, enhance immunity, help blood coagulation regeneration and lower cholesterol. ▲ α -linoleic acid: It plays a very important role in the visual system and nervous system, and can reduce the level of triglycerides in the blood, thus reducing the formation of atherosclerosis and thrombosis. Therefore, unsaturated fatty acids have the function of preventing cardiovascular diseases. Secondly, vegetable oil is the best source of vitamin E, which is a fat-soluble vitamin with antioxidant effect and can devour free radicals leading to aging. Vegetable fat is rich in vitamin E. In order to make better use of the benefits of vegetable oil, we should pay attention to the following points when choosing vegetable oil: 1. In order to absorb all kinds of nutrients in vegetable oil as comprehensively as possible, it is very important to choose diversification. It is best to choose different oils in turn. 2. Fatty acids are sensitive. In order to better protect fatty acids, vegetable oil should be stored away from light. 3. Some fatty acids are easily destroyed at high temperature. Therefore, peanut oil, corn oil, olive oil or sunflower oil are the best heating oils. If you want to add some flavor to salad or cold salad, you can choose oil with spices, such as garlic or ginger. Follow-up: But I used it for cooking. Isn't it equivalent to this oil being squeezed dry by me? It's not healthy to eat. Isn't it the same as usual oil? Answer: no, it is fried and then squeezed, and more oil is produced. The quality of oil is totally unfounded. In addition, the boiling point of oil is about 120 degrees. How to break it in a pot with vegetables? Of course, you have to eat boiled oil to eat oil. This can fully decompose fatty acids that are easily absorbed by adults. But the oil that has been cooked many times will not work. It will contain carcinogenic fatty acids, and there are many precipitates in the oil of fried food. This is it. It is no longer suitable for cooking. Follow-up: But I heard that eating oil above 90 degrees is bad for the cell wall of human cells, because oleic acid replaces the original cell wall of human body and changes the boundary of material exchange. Answer: Oh, absolutely. Oil is the least perishable thing, just like lubricating oil. If heated slightly, it will become toxic. Oil is mainly fat. When fat is stored in the body, it either becomes energy or fat, and some of the remaining fat is decomposed by the liver and excreted. Nothing can become a cell wall or something. Cell walls are also cells. Do you think chemicals can become living cells? Follow-up: The main component of cell wall is phosphoric acid, which is a kind of fatty acid. It must come from food fat. Answer: I think you are struggling with this problem, as if you want to breathe this dusty air. Do you want to keep breathing or find a glass cover to cover your head? People have evolved the ability to choose advantages and disadvantages. Don't say that fat is harmful. You should consider fasting. Do you think oil will smell good if it is not heated? Do you think you can fry cooked vegetables without heating? It's really boring Follow-up: In the past, people seldom got sick, but there are all kinds of strange diseases in modern life. Many people get senile diseases when they are young. It's time to reflect on our diet and living environment. Follow-up: If you say this, it will be boring for human beings to think so. If everyone has your attitude, science and technology will not progress and human beings will not develop. Answer: Then you really should believe in Buddhism. Heaven has a place for you. If you can't go, just live honestly and choose your ideal food again slowly. The present environment was originally caused by scientific and technological progress. Do you dare to say whether you want scientific and technological progress? Are you too neurotic to eat oil? -
