Fish reduce prestunost and depression all we meet a lot of contradictory information about the use of fish. For example, how much fish we should eat? What type should it be?
On the one hand we are told to eat fish a lot and regularly. On the other hand say that many of the fish are close to degeneracy, such as cod.
So, how much you should eat fish. Fish helpful. So helpful, that food standards agency recommends that it is much more. At least two servings of fish (fresh, frozen or canned) in a week, at least one of these portions should be oily fish. “Oily” fish – mackerel, salmon, perch, herring, trout, sardines and fresh (not tinned) tuna. And white fish – such as cod, haddock, monk fish, etc. – And oily fish – an excellent source of protein, vitamins and minerals, but oily fish is particularly nutritious. The representative of the British Association of Food Sarah Schenker explains: “White fish – it is mainly protein and water. In the composition of fatty fish is completely different. There’s more fat – more than some types of meat – but the fat is completely different than in the flesh.
“Secret Weapon” oily fish – fatty acid omega-3. Various studies have shown that omega-3 prevents heart disease, improve IQ, strengthens the immune system, weakens the symptoms of arthritis and helps with certain skin diseases. Some studies have also shown that omega-3 helps dyslexic patients, reduces the level of crime among juvenile delinquents and removes depression. Fish with the highest content of omega-3 – mackerel (mackerel), which contains up to 30 grams of fat per 100 g of fish, from which omega-3 is five percent.
However, in fatty fish is and negative sides. Compared with other varieties, it is higher in the food chain, which means that their meat accumulate such pollutants as dioxins, mercury, polychlorinatedbiphenyls in the marine ecological system. For this reason, in 2004, Food Standards Agency advised to limit consumption of fatty fish. Agency advises that “girls and women who once would have children, and pregnant or breastfeeding women can eat up to two servings of oily fish a week. Other women, men and boys can have up to four portions of oily fish a week. ” Besides fish, marlin, shark and swordfish are not recommended for use boys and girls under 16 or pregnant women or women who have children in the future.
But put aside the warnings, the council remains the same: eat more fish. Here comes another problem – the world’s oceans are so perevyuzheny that some types of fish such as cod, are threatened with extinction. The Organization for products and agriculture of the United Nations reported that 25% of inadequate exploitation, 47% fully exploited, 15% too exploited, while 10% have already been exhausted and are slowly recovering.
The good news is that we – consumers – can help the situation. And this does not necessarily stop eating fish. Try to buy a variety of fish such as saithe.
