Eating onion alone to lower blood lipids is really unrealistic. Onions have no direct effect on reducing blood lipids, but onions contain some active ingredients that can help us stabilize blood lipids. However, the effects of diet therapy cannot be immediate. Depending on the individual’s constitution, the difference in absorption and digestion, or the response to food ingredients, the effects of eating onions may also differ. We should treat them rationally.
Having said that, is onion effective in lowering blood lipids?
Some active ingredients in onions do help lower blood lipids. We cut into tears when we cut onions. This is because onions are rich in sulfur compounds, such as diallyl, which are irritating and have irritating effects on eyes, nose, and throat, but these sulfur compounds can be extraordinary. For example, it can promote gastric acid secretion, help increase appetite, and enhance food digestion and absorption. These sulfur-containing compounds also help block blood lipid formation, so they have the potential to reduce lipids; sulfur-containing compounds can also inhibit lipoproteins in tests. The accumulation of blood vessel walls has the effect of preventing cardiovascular and cerebrovascular diseases. Onion is also the only food in vegetables that contains “prostaglandin A”. Prostaglandin A is an active ingredient that helps to reduce the viscosity of blood lipids and increase blood flow to the filling arteries, thereby helping to prevent the formation of blood clots. Flavonoids, polyphenols, and other ingredients can be extracted from onion skin. These ingredients also help to resist free radicals, delay vascular aging, and prevent vascular disease.
Onion is also a vegetable with a relatively high dietary fiber content. Dietary fiber also contributes to the prevention of obesity and the three highs. It is a favorable assistant for controlling sugar and fat. Dietary fiber cannot be directly digested and absorbed by the stomach and intestines. It is also because it is difficult to digest and absorb, so it can increase the digestion time of food, delay the absorption of fat, cholesterol, and sugar, and also absorb some cholesterol, fat, and sugar, and reduce their absorption It has a good auxiliary effect on smoothing postprandial blood glucose and reducing cholesterol absorption. Appropriate onion intake has the effect of assisting fat control, but onions are not effective to eat. We can often eat appropriately and assist fat control, but eating a few more a day may not necessarily achieve the effect of reducing fat, but may Causes uneven nutritional intake.
In fact, in addition to onions, many vegetables have an auxiliary adjustment effect on obesity, three advanced chronic diseases, etc. Vegetables are rich in dietary fiber, plant pigments, water-soluble vitamins, and most of the vitamins and plant pigments have antioxidant effects and help resist Free radicals delay aging of blood vessels. Folic acid is rich in fruits and vegetables. Folic acid can help inhibit lipoprotein accumulation and prevent atherosclerosis and vascular disease. The dietary guide recommends a daily intake of 500g of vegetables, but many friends ca n’t reach this intake. Adequate intake of fruits and vegetables can help prevent obesity, the three highs, and it is best to have 8 kinds of vegetables daily. There are at least 5 types of entry.
