The role of omega -3
(1) can promote the excretion of neutral or acidic cholesterol in feces, inhibit the synthesis of lipids and lipoproteins in liver, reduce cholesterol, triglycerides, LDL and VLDL in plasma, and increase HDL.
(2) Participating in the metabolism of arachidonic acid. Produces prostaglandin compounds PGI3 and TXA3. The metabolites of arachidonic acid are prostacyclin (PGI2) and thromboxane (TXA2). PGI2 can relax blood vessels, prevent platelet aggregation and prevent thrombosis. TXA2 can cause vasospasm, promote platelet aggregation and thrombosis. PGI3 has the same function as PGI2; But TXA3 does not have the function of TXA2. Therefore, EPA and DHA can dilate blood vessels, prevent platelet aggregation and prevent thrombosis.
(3) Anti-arrhythmia, reducing heart rate
④ Lowering blood pressure
Can be used for treating hyperlipoproteinemia, atherosclerosis and coronary heart disease.
Omega 3 food source
Seafood such as fish and shrimp and deep-sea fish oil are the main food sources of EPA and DHA.
Omega 3 family-Allah
Efficacy: It is the main component of human tissues and cells, and can promote the absorption of various nutrients. About 7% of ALA in the body can be converted into DHA and EPA.
Main food sources: fruits, vegetables, nuts and edible oil.
Seeing this, I believe everyone understands that omega-3 fatty acids are a big family, closely related and complementary; ω-3 is not equal to fish oil. EPA, DHA and ALA in plants such as flaxseed oil contained in fish oil are only one kind of omega-3 fatty acids.
It is a correct way to supplement omega-3 and an effective way to get rid of sub-health.
After understanding the many benefits of Omega 3, we should learn to choose good Omega 3 products.
How to eat deep-sea fish oil with good effect
How to eat deep-sea fish oil with lecithin?
In fact, there should be a correct understanding of how to eat deep-sea fish oil. For example, when we take deep-sea fish oil, it is best to advise people to take it with some lecithin. Many middle-aged and elderly people don't know much about this. The main reason for doing this is to let people pursue better results. In fact, in life, if deep-sea fish oil is used in this way, it can also make deep-sea fish oil play a better role, and it is inseparable from the help and cooperation of lecithin.
EPA in deep-sea fish oil can inhibit the synthesis of triglycerides and cholesterol, remove fatty plaques attached to blood vessel walls and prevent platelet aggregation. Lecithin can emulsify large fat plaques into small fat particles, prevent fat plaques from adhering to blood vessel walls, and make blood flow smooth. The combination of the two products can effectively reduce blood lipid and prevent atherosclerosis and thrombosis.
Deep-sea fish oil is a vascular scavenger. Its job is to clean up excess cholesterol and other garbage together, but the sweeper needs a garbage truck to transport the garbage out of the body. This garbage truck is lecithin! It can transport excess lipids to the liver and promote lipid metabolism in the liver. The combination of the two drugs has an ideal effect of lowering blood pressure and lipid, and has a better effect of protecting liver. Soybean lecithin and deep-sea fish oil have some similar functions, but they are different. If they are taken together, they complement each other and are more suitable for the health care of middle-aged and elderly people.
How to eat deep-sea fish oil: baby's food proportion and taking time
Cod liver oil contains vitamins A and D. Lack of vitamin A may affect the development of baby's skin and vision, and lack of vitamin D may lead to rickets, because vitamin D can promote the absorption of calcium in food and play an important role in baby's bone development. The contents of vitamins A and D in breast milk and milk are relatively small. In order to meet the needs of baby's growth and development, whether breastfeeding or artificial feeding, cod liver oil should be added from the third week after birth. At present, there are vitamin AD preparations specially made for infants in the market, which are scientifically matched and suitable for infants to absorb, but the concentrations are different. It should be given to babies in strict accordance with the instructions or doctor's advice, and it is best to choose drops. Pay special attention not to supplement too much, otherwise poisoning may occur.
In summer, the baby has more outdoor activities and long sunshine time, so the dosage of cod liver oil can be appropriately reduced. Many older babies often refuse to eat cod liver oil because they don't like its fishy smell. Mom needs to think of some ways, such as mixing it with the baby's favorite food and letting him eat unconsciously. Or prepare some snacks as a reward. Usually, you should prepare more foods rich in vitamins A and D for your baby, such as animal liver, egg yolk, shrimp skin, carrots and so on.
In winter, the sunshine is short, so you should eat cod liver oil every day. Avoid feeding cod liver oil with milk powder, otherwise it will affect absorption. If the spring is sunny, you can eat for ten days and stop for ten days. Stay in the sun for more than 20 minutes when the sun is fine. Be careful not to sunbathe through the glass. It is effective to sunbathe exposed skin. Sunlight can convert dehydrocholesterol in the baby's body into VD, which is helpful for calcium absorption. If your baby has calcium deficiency symptoms, you can still eat cod liver oil every day. It is sunny in summer, and cod liver oil can be reduced appropriately.
Supplementing cod liver oil can make your baby absorb calcium better. It is best to eat cod liver oil in the morning, which can help the baby absorb calcium in one day. At the same time, always take your baby out to bask in the sun, which is the same as cod liver oil. Cod liver oil does not need to buy imported cod liver oil, which is very expensive and the effect is actually the same. Cod liver oil is usually supplemented to two years old. If the baby has more than one hour of sunshine during the day, there is no need to eat. Babies in the first four months can eat cod liver oil once every two days, or two or three drops a day.
What are the side effects of deep-sea fish oil?
Generally speaking, it is safe for most people (including pregnant women and lactating women) to take less than 3 grams a day, and there will be no side effects of deep-sea fish oil. Taking too much deep-sea fish oil can lead to blood coagulation and increase the risk of bleeding. Possible side effects of deep-sea fish oil include burping, halitosis, heartburn, nausea, loose stool, rash and nosebleeds. Taking deep-sea fish oil supplements with meals can usually reduce these side effects. Some fish, especially sharks, mackerel and farmed salmon, may be polluted by mercury and other chemicals. Therefore, when choosing fish oil supplements, we should choose high-purity fish oil products extracted from deep-sea pollution-free fish. Green sea fish or deep-sea small fish ensure the lowest environmental pollution in the food chain and are relatively safer.
1, experts believe that DHA contained in natural fish oil is an important element for the growth and maintenance of nervous system cells. Although EPA contained in fish oil can also regulate blood lipid and soften blood vessels, it should be understood that fish itself cannot synthesize DHA, but its purity is not high because it accumulates in the body after eating algae containing DHA. Merchants often exaggerate or even falsely publicize the brain-strengthening and intelligence-improving effects of fish oil. With the increasingly serious environmental pollution, heavy metal pollution such as mercury is easy to remain in fish oil, which is harmful to human body.
2. Another expert pointed out that because some fish contain mercury and a large amount of mercury pollutants exist, it will damage the developing nervous system of newborns and children, so infants should be careful to eat fish oil. Studies in the United States have proved that long-term adequate intake of DHA can improve children's IQ by 7% and UFF0C's vision by 0.2%. U3002 is rich in DHA and has become a "tonic" for some parents. However, infants and young children lack corresponding enzymes, so they can't "detoxify" mercury in deep-sea fish oil, and the effect may be counterproductive after taking it.
3. Infants, children and adolescents need to supplement unsaturated fatty acids, but it is not recommended to supplement them from fish oil capsules, but to supplement them normally from food, such as using edible oil containing algae oil DHA. In infants, children and adolescents, the number of brain cells does not increase with age after birth, the network of nerve cells needs to be increased, and the brain cells need to be rich, all of which require a lot of DHA and EPA. Supplementing unsaturated fatty acids also has the health care function of improving memory.
4. Fish oil is rich in DHA and EPA, which can not be ignored by the elderly. It can delay brain atrophy and prevent brain function decline. It is safe for most people to consume less than 3 grams of deep-sea fish oil every day. Taking too much deep-sea fish oil can lead to blood coagulation and increase the risk of bleeding.
The following people with diseases or symptoms should pay special attention when taking fish oil: high-dose intake of fish oil in patients with liver disease may increase the risk of bleeding in patients with liver disease. People who are allergic to seafood may also have allergic symptoms when taking fish oil supplements. Therefore, such people need to be cautious when choosing fish oil products. High doses of fish oil may aggravate the symptoms of bipolar patients. However, studies have shown that appropriate doses of fish oil can improve bipolar depression. Depression: Eating high doses of fish oil may aggravate depression. Eating high doses of fish oil in diabetic patients may make it more difficult to control blood sugar. Deep-sea fish oil can lower blood pressure in patients with hypertension. Therefore, people who are taking antihypertensive drugs, taking high doses of fish oil may lead to low blood pressure. Familial adenoma polyp
Intake of high doses of fish oil may further increase the cancer risk of patients with familial adenomatous polyp.
