@Eastman Interesting hypothesis. And it could be 100% true but I just want to point out a few things. This is in no way to be taken as a criticism for your post. As I said, it could be true:
a) All the testing was done in vitro and using a known quantity of mercury in stomach acid. This doesn't even come close to what is going on in vivo. For example, does the addition of bile salts and pancreatic enzymes affect the affinity of soluble fibre for Hg or does the gut flora change anything?
b) The main problem with mercury is the 15-20 year (likely 20 for those of us with methylation issues) half-life in the brain. (This half-life only starts after all exposure to Hg stops.) This is also a way that mercury is unique. Becoming trapped and with time, concentrated behind the blood-brain-barrier. Strawberries do not cross the BBB and will do little to really help a person who is experiencing the symptoms of toxicity.
c) My diet was high in lots of these foods. We had over 1/4 acre in strawberries on the farm and peanut butter was a mainstay at our house. Peanut butter and maple syrup are to die for.
d) It is generally accepted that most of us will have our greatest Hg exposure from our dental fillings this form of mercury is absorbed at 80% and bypasses the gut entirely. Foods are not going to be a big help.
e) One of the problems with ideas like this is that a person is entreated to waste time following them. Anyone seriously toxic needs to get a Hair Test and move forward with chelation. This is a true poisoning and there can be permanent damage. Time matters. If they also wish to add some of these foods to the diet, fine....but chelate, chelate, chelate.
f) So it could be a helpful adjunct but I doubt that it is a big gun. I would like to know the mercury loading of vegetarians who eat a lot of these foods. Including those who eat fish and those who choose not to, compared with the rest of us.
g) At the end of the day, I suspect that the equation of "mercury in" and "mercury out" (and associated genetics) will have a greater impact on toxicity that the number of strawberries eaten.
Thank-you for bringing this article to my attention.
