To eat or not to eat fish

Updated on November 18, 2009

Eating fish is one of the most advised by doctors and the best alternative in keeping healthy. It is the best diet for those who are keeping their blood cholesterol levels in check because it contains omega 3 which is a useful fat for the conversion or utilization of bad cholesterol (LDL), that why it is known to be good for the heart. Other than this, eating fish also proves beneficial to people who are suffering from asthma, depression, diabetes mellitus and even arthritis.

However, eating fish also has its drawbacks because recently, studies have shown that fish contains varying amounts of mercury. This is an element that has a capacity to give off harmful effects to the human system, most specifically to the brain, nerves, kidney, eyes, skin and other vital organs.

Why so?

Most likely because of the industrialization which in turn causes the waters to be polluted, and of course it is the only habitat of dear fishes.

How come?

Mercury, as well as other elements that comes from the industrial wastes which is unfortunately drained to the sea can accumulate in the seabed or any water form this wastes are directed to. While in the water, this mercury will be converted to methylmercury which, when ingested, can be fatal to the humans.

Fish then absorbs this in its system on varying amounts, depending on what they eat and how long have they lived in the water. So this might mean that the bigger the fish we eat or the more it is aged when eaten, the more it harbored mercury and the smaller the fish that is served on our tables, the safer they become.

Uh uh, this bit of news is somewhat scary and it is something that we just cannot afford to ignore because it concerns our health. When I have read about it somewhere, of course I have to make changes on my menu, as well as on my diet.

      I heard about mercury in fish too. I do eat at least 2 to 3 portions a week, and I have asked about the mercury thing. People say it is small amounts. But how small is small. It is good to know these things. Good Hub!
