Not to mention the dioxins..
Depends on several things when it comes to that and mercury in fish, etc, but I will get to the dioxons in a little while.
When it comes to minimizing mercury and stuff, the type of sea food you buy and where it is from will help, but sea creatures and many that live in the rivers naturally contain mecury in their bodies from water running down the rivers and erosion washing the mercury out of the rocks in the water; not only from pollution. Tuna has a lot of mercury but shrimp and maybe sardines don't so much. If they are creatures and predators from the bottom, they will have much more. Also drinking green tea helps negate the toxins in the seafood preventing the absorption of most of it. The Japanese eat seafood all the time and are very smart on average and don't appear brain damaged, and they are fine since they know what they are doing, obviously. That seafood has omega 3's which help your brain and heart. That diet coupled with their love for learning as a culture is probably why the average Japanese is so smart.
The reason mercury is bad is because if you get enough of it in your blood, it can collect inside your tissues and can't be removed normally, and common sense tells me that it is bad because it may block blood flow and electrical signals as a result of sitting in your flesh. Kind of like how any poison blocks the flow of fluid and other things.
Also, I do agree that you must be careful where you buy your green tea from. I use Stash premium green tea that I buy from Fred Meyer's. It claims to come from Brazil and is grown in an area that uses no pesticides. I also went to their website around the time I started drinking it and I feel better physically and mentally when drinking this vs another brand I tried.
Sad thing about the dioxins is that you can't completely eliminate your exposure to them in industrialized countries, but you can minimize them by staying away from certain products or chemicals and doing research and not using hair dye, hair gell, colon, or perfume, and not using very strong detergent, and being careful what kind of soap you buy among other practices.
I know, off topic, but I was just replying to this.
So out of control administrators, low standards, and bad attitudes about school has nothing to do with it?
I also think that is a problem, Kosh. Too many people in this culture don't value education and the average teachers here don't seem to be as good as ones from some other countries. Also, these schools aren't strict or disciplined enough and they even let kids buy junk food and energy drinks at school, almost like they encourage it, which could cause problems and may explain some of what causes a high obesity rate with many kids and a lower energy level more so these days here, since kids are much less likely to moderate what they eat or know the risks. It sounds messed up. But that is the price you pay when there is too much freedom and no balance.
