What's good about fish oil?
The main basis for eating fish to become smart and reduce the three highs comes from DHA and EPA in fish oil. DHA promotes brain development and prevents Alzheimer's disease; EPA softens blood vessels and reduces the three highs. Neither DHA nor EPA can be synthesized by the human body itself, but only through food intake.
As early as 197 1, Danish scientists found for the first time that Eskimos who often eat marine fish rarely suffer from myocardial infarction and thrombosis, and then scientific research became more and more in-depth. Up to now, there are more than 20,000 scientific literatures about fish oil, which proves the valuable nutritional value of DHA and EPA.
1. What's so good about fish oil?
1.DHA promotes brain development and prevents Alzheimer's disease.
DHA, known as "brain gold", is an essential element for synaptic growth, which can directly enter the brain and be absorbed.
DHA supplementation can maintain the normal information transmission between brain nerve cells, make the brain get sufficient nutrition, and then improve the vitality of brain cells, increase memory, responsiveness and learning ability, which is an essential nutrient for infants and pregnant women.
At the same time, for middle-aged and elderly people, DHA can improve the atrophy of senile nerve fibers, make brain nerve fibers grow again, and achieve the effect of preventing and improving Alzheimer's disease.
2.EPA can prevent thrombosis and reduce the incidence of cardiovascular diseases.
Platelets coagulate in the blood to form small blood clots, which will block blood vessels. EPA can replace arachidonic acid on platelet membrane, thus reducing the synthesis of thromboxane, inhibiting platelet aggregation and preventing cardiovascular and cerebrovascular obstruction.
EPA can also effectively reduce the concentration of cholesterol and oil in blood, activate the cell membrane of vascular wall endothelium, make blood vessels full of elasticity and easy to relax, and control the rise of blood pressure. It has a benign effect on some chronic diseases, such as three highs, obesity, asthma and cardiovascular diseases.
Second, how to choose fish oil capsules?
1. First of all, wild salmon oil is internationally recognized as the best. Produced in the deep sea, it is pollution-free, with more stable ratio of EPA and DHA, lower cholesterol and richer nutrition than farmed salmon.
2. Followed by tuna fish oil. The disadvantage is that EPA and DHA must be ethylated to meet the standard, with poor absorption and many side effects.
3. The third is the fish oil of miscellaneous fish in shallow water, such as firewood and sardines. The disadvantage is that the contents of EPA and DHA are not up to standard, and shallow water fish are easy to be polluted.
Third, how to buy fish oil!
1. Look at the packaging: the outer packaging of regular fish oil products must have the approval number of the health department and the blue hat mark of health food.
2. It depends on the date of production: at room temperature, the shelf life is 2-3 years.
3. Look at the content: the average natural fish oil product contains DHA 12mg and EPA 18mg.
4. Look at the capsule: the shell of high-quality fish oil soft capsule should be made of high-quality bone glue, and the capsule particles are uniform and contain no impurities. Warm water of 70-80 degrees Celsius can dissolve the broken capsule skin.
5. Look at the color: the better fish oil is light yellow with crystal clear color and good oil permeability. And inferior products often have rough appearance and turbid contents.
6. Taste: high-quality deep-sea fish oil soft capsules should have a faint fishy smell after biting. If the fishy smell is too strong, it is extracted from miscellaneous fish; If there is no fishy smell, it is a fake and shoddy product.
7. Refrigeration: If high-quality fish oil and ordinary fish oil are put in the refrigerator for more than 30 minutes at the same time, ordinary fish oil will solidify and freeze below zero degrees Celsius, while high-quality fish oil has good fluidity.
Fourth, how to eat fish oil correctly?
Health care: take a small dose, once a day, one pill each time.
Adjuvant treatment: at first, you can use a large dose, twice a day, one pill in the morning and one pill in the evening; After 3 months, it can be reduced, once a day, one pill each time to maintain the curative effect.
Old people: Fish oil+lecithin is an ideal choice. Many elderly people have hyperlipidemia, so it is best to take lecithin while taking fish oil to achieve the purpose of complementing each other. Because when fish oil lowers blood lipids, its metabolites pass through the liver, which means that the burden on the liver will increase. If fish oil and lecithin are taken together, it will not only help to lower blood lipids, but also enhance the excretion function of the liver, thus protecting the liver from damage.
Finally, special emphasis is placed on:
1. Fish oil can't replace medicine, let alone be expected to cure diseases.
Fish oil is different from cod liver oil, which mainly contains vitamin A and vitamin D. It is often used to prevent night blindness and rickets. Don't get mixed up.
