Nutritional composition of fish oil

Fish oil has many health benefits. Besides preventing heart attacks and deaths from irregular heartbeats in people with coronary artery disease, fish oil also works to reduce triglyceride levels in the blood. So what ingredients make fish oil such an important nutrient?

Fish oil can be supplemented by consuming fish or taking supplements in capsule form. Certain types of fish are high in oil, such as mackerel, herring, tuna, and salmon. Two of the most important omega-3 fatty acids found in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
Fish oil offers many health benefits thanks to its omega-3 fatty acid composition. In fact, the human body cannot produce this nutrient on its own. Therefore, taking fish oil as a way to supplement omega-3 fatty acids for the body. In addition, omega-3 fatty acids have a role in reducing pain and swelling. This may explain why fish oil is so effective for psoriasis and dry eyes.

Based on the nutritional components of fish oil, experts have listed the benefits that fish oil brings as follows:

Previous evidence suggests that fish oil can reduce heart attacks and deaths from irregular heart rhythms Survival rates in pregnant women with antiphospholipid syndrome. Fish oil improves attention, mental function and behavior in children 8-13 years of age with attention deficit hyperactivity disorder (ADHD). Other research shows that taking fish oil and evening primrose oil supplements (Eye Q, Novasel) improves mental function and behavior in 7-12 year olds with ADHD. Taking fish oil along with conventional bipolar disorder treatments seems to improve symptoms of depression. Cancer patients should be prescribed high doses of fish oil to slow weight loss Cyclosporine is a drug that reduces the risk of organ rejection after transplantation.

High doses of fish oil can also decrease the activity of the immune system and the body's ability to fight infections. This is of particular concern to organ transplant patients and the elderly. Some of the side effects of fish oil such as:
Fish oil can cause side effects including belching, bad breath, heartburn, nausea, loose stools, rash and nosebleeds.

Therefore, people taking warfarin should avoid taking fish oil. Fish oil has the effect of reducing some levels of fat in the blood. These fats are called triglycerides. Birth control pills can decrease the effectiveness of fish oil by reducing the amount of this fat in the blood. Some birth control pills including ethinyl estradiol and levonorgestrel (Triphasil), ethinyl estradiol, and norethindrone Orlistat (Xenical, Alli) interact with fish oil: This is used for weight loss. It prevents dietary fat from being absorbed from the intestines. There is some concern that orlistat (Xenical, Alli) might also decrease the absorption of fish oil when they are taken together. To avoid this interaction, you should take orlistat (Xenical, Alli) and fish oil at least 2 hours apart. Fish oil has many health benefits. However, we need to supplement fish oil with appropriate doses, to avoid overuse to cause unwanted side effects.
