Differences of Fish Oil, Omega 3 and Cod Liver Oil Its Benefits and Sources

Fish Oil

Fish oil comes from the tissues of oily fish. The best sources are cold-water, fatty fish. When it comes to human consumption of fish oil, you can get it from fish themselves or from a fish oil supplement.Fish oil is a concentrated source of omega-3 fats, which are also called ω-3 fatty acids or n-3 fatty acids. It should be noted that fish oil can also reduce triglycerides in people with high triglyceride levels. However, it can also increase cholesterol, so care should be taken before supplementing fish oil for this purpose.

Many people focus on the dosage of fish oil to take, like 1000 mg or 1200 mg, but it is really the omega-3s that matter. The two types of omega-3 fatty acids to focus on are EPA and DHA. These omega-3s are naturally found in oily fish like salmon, halibut, sardines and anchovies, and are the very reason why fish oil supplements have received such high praise.

Both omega-3 and omega-6 are essential fatty acids, which means the body cannot make them, they must be obtained from the diet. For most of human history, these fatty acids were present in the diet in roughly equal amounts. However, modern foods provide an overabundance of omega-6 fatty acids, mostly from refined vegetable oils that are used in fried food as well as snack foods, cookies and crackers. Omega-3s, conversely, are now relatively rare in American diets. The result is an imbalance of these essential fats that drives inflammation and promotes several diseases.

Omega-3 Fatty Acids

Omega-3 fatty acids are considered essential fatty acids. They are necessary for human health, but the body can’t make them. You have to get them through food. Omega-3 fatty acids are found in fish, such as salmon, tuna, and halibut, other seafoods including algae and krill, some plants, and nut oils.

Studies show strong evidence that omega-3 fatty acids from fish oil can lower blood pressure and triglyceride levels. There’s also good evidence that diets high in omega-3 fatty acids help with rheumatoid arthritis as well as osteoarthritis. Past evidence pointed to omega-3 fatty acids reducing risk of heart attacks, strokes, and death from heart disease, but recent research has refuted some of these findings. More specific research is needed to sort this out.

Cod Liver Oil

Cod liver oil is a nutritional supplement derived from liver of cod fish. As with most fish oils, it has high levels of the omega-3 fatty acids, eicosapentaenoic acid and docosahexaenoic acid.

People living in parts of northern Europe have been using cod liver oil for centuries to enhance immunity and protect them from dark, long winters. They have also used cod liver oil as a natural solution for rheumatism, aching joints and stiff muscles.Cod liver oil can be obtained from eating fresh cod liver or by taking supplements.

Cod liver oil is used for high cholesterol, high triglycerides, kidney disease in people with diabetes, high blood pressure, heart disease, osteoarthritis, depression, an autoimmune disease called systemic lupus erythematosus (SLE), glaucoma, and middle ear infections(otitis media).

Some people put cod liver oil on their skin to speed wound healing.

Oily fish are a rich source of vitamins A, D and E. They are also rich in essential omega-3 fatty acids which are essential for healthy brain, eye and nerve development in babies and children. They are also beneficial to your heart health and there is emerging evidence to suggest that eating fish reduces the risk of cancer and arthritis.That’s because fish and shellfish are good sources of many vitamins and minerals. Oily fish – such as salmon and fresh tuna – is also particularly high in long-chain omega-3 fatty acids, which may help to keep your heart healthy.
