photo results | Fish oil | Fish oil is oil derived from the tissues of oily fish.
Fish oil is recommended for a healthy diet because it contains the omega-3 fatty acids, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), precursors to eicosanoids that reduce inflammation throughout the body. Fish do not actually produce omega-3 fatty acids, but instead accumulate them from either consuming microalgae that produce these fatty acids, as is the case with fish like herring and sardines, or, as is the case with fatty predatory fish, by eating prey fish that have accumulated omega-3 fatty acids from microalgae. Such fatty predatory fish like mackerel, lake trout, flounder, albacore tuna and salmon may be high in omega-3 fatty acids, but due to their position at the top of the food chain, these species can accumulate toxic substances (See biomagnification). For this reason, the FDA recommends limiting consumption of certain (predatory) fish species (e.g. albacore tuna, shark, and swordfish) due to high levels of toxic contaminants such as mercury, dioxin, PCBs and chlordane There are vegetarian, DHA Omega-3 products made from algae available if toxic contaminants are of concern. | |

 | Oily Fish | Oily fish, oil-rich fish or pelagic fish are those fish which have oils throughout the fillet and in the belly cavity around the gut, rather than only in the liver like white fish. Oily fish fillets may contain up to 30 percent oil, although this figure varies both within and between species. Oily fish generally swim in the pelagic zones of the oceans and are usually cold water fish (while white fish are warm water fish).
Oily fish are a good source of Vitamins A and D as well as being rich in omega 3 fatty acids (white fish also contain the same nutrients but at a much lower level). For this reason the consumption of oily fish can be more beneficial to humans than white fish, particularly concerning cardiovascular diseases, but oily fish are known to carry higher levels of contaminants than white fish. Amongst other benefits, studies suggest that the omega 3 fatty acids in oily fish may help sufferers of depression, reduce the likelihood of heart disease and improve inflammatory conditions such as arthritis. | |
