The main effects of polyunsaturated fatty acids

N-3 polyunsaturated fatty acids: a type of unsaturated fatty acids.

The main effect of unsaturated fatty acids is to reduce blood cholesterol and triglycerides, and enhance memory and thinking ability.

Polyunsaturated fatty acids can be divided into W3 and W6 polyunsaturated fatty acids according to the position of the first double bond starting from the methyl terminus, among which W3 is a necessity for the human body like vitamins and minerals, and insufficient can easily lead to disorders of important organs such as the heart and brain, and the two most important unsaturated fatty acids in W3 saturated fatty acids for the human body are DHA and EPA, EPA is the English abbreviation of eicosapentaenoic acid, which has the function of cleaning up garbage in blood vessels, commonly known as it"Vascular scavengers"DHA is the English abbreviation of docosahexaenoic acid, which has the effect of softening blood vessels, strengthening the brain and improving eyesight, commonly known as DHA"Brain**"。

The specific effects of polysaturated fatty acids are as follows:

Maintain the relative fluidity of the cell membrane to ensure the normal physiological function of the cell. Esterify cholesterol and reduce blood cholesterol and triglycerides. Reduces blood viscosity and improves blood microcirculation. Improves the activity of brain cells, enhances memory and thinking skills. Positive cover.

We will often encounter monounsaturated fatty acids in our lives, in fact, monounsaturated fatty acids are very different from some other fatty acids, many people do not understand, what is the role of unsaturated fatty acids?

Unsaturated fatty acids maintain the relative fluidity of cell membranes to maintain the normal physiological function of cells. Reducing dietary fat and cholesterol intake and appropriately increasing the intake of monounsaturated fatty acids are very effective in reducing blood lipid levels and controlling blood pressure in people with high blood pressure. It can also improve the activity of brain cells and enhance memory and thinking skills.

If it does not have polyunsaturated fatty acids, it is easy to produce lipid peroxidation reaction, promote chemical carcinogenesis and inhibit immune function and other adverse effects.

Vegetable fats contain a lot of unsaturated fatty acids. In vegetable fats, it contains about 80% 90% unsaturated fatty acids and 10% 20% saturated fatty acids, but most of the unsaturated fatty acids are polyunsaturated fatty acids, and only a few contain more monounsaturated fatty acids, such as tea oil and olive oil, the oleic acid content is more than 80%, and the content of palm oil is also higher, about 40% or more.

Unsaturated fatty acids are all fatty acids except saturated fatty acids. It is an essential nutrient for the human body, which can maintain the vitality of brain cells, thereby enhancing the brain's thinking ability and improving memory ability. It can effectively decompose cholesterol, reduce the viscosity of blood, facilitate the recovery of patients with cardiovascular and cerebrovascular diseases, and effectively reduce hypertension.

The main cause of myopia is the reduced ability of the ciliary muscle to regulate the lens. Modern medicine has shown that unsaturated fatty acids have a significant effect on improving vision. Nuts contain a lot of unsaturated fatty acids, and nuts are usually hard, chewing hard things for a long time can strengthen the facial muscles, and vision can be improved.

Ode to the Rock Palace. Cardiovascular and cerebrovascular diseases are more likely to occur in people with insufficient intake of unsaturated fatty acids, which can easily lead to atherosclerosis, so they are more likely to suffer from cardiovascular and cerebrovascular diseases.

Unsaturated fatty acids have the effect of maintaining brain function, and if the intake is insufficient, it will affect the brain's rough thinking ability and make people's memory decline. Insufficient intake in children can affect mental development, and if the elderly do not have it, the risk of developing Alzheimer's disease increases.

The intake of unsaturated fatty acids also needs to be reasonably controlled, excessive intake will affect the synthesis of many substances in the human body, and will increase the risk of cancer, which needs to be paid attention to.

Some unsaturated fatty acids, which cannot be synthesized by the human body, must be obtained from food. Vegetables rich in unsaturated fatty acids include various soy products, mushrooms, radish, tomatoes, winter melon, etc.; Fruits include apples, oranges, pomegranates, and so on; Nuts are also rich in unsaturated fatty acids.

1. Unsaturated fatty acids.

Fatty acids other than saturated fatty acids (fatty acids that do not contain double bonds are called saturated fatty acids, and the main fatty acids of all animal oils are saturated fatty acids, except for fish oil) are unsaturated fatty acids.

Unsaturated fatty acids are a type of fatty acids that make up body fat, and the human body does not have fatty acids that are lacking. According to the number of double bonds, unsaturated fatty acids and fatty acids are divided into monounsaturated fatty acids and polyunsaturated fatty acids.

2. Role. Deep-sea fish oil supplemented with diet can promote the metabolism of saturated fatty acids in the body, reduce and eliminate the harm of animal fats (mainly from fatty meat, dairy products, etc.) in food to the human body, prevent fat from being deposited in the blood vessel wall, inhibit the formation and development of atherosclerosis, and enhance the elasticity and toughness of blood vessels. Reduces blood viscosity and increases the oxygen-carrying capacity of red blood cells.
