    Saw you speak at the NHA convention, really enjoyed your style of delivering a very important message. I’m here at the Regency health spa detoxing from sugar and aspartame.

    Understood that we should limit or eliminate fish intake, but what about the argument here?

    They still have mercury in vaccines. Is that a concern? I assume you are a proponent of vaccines, that the protection outweighs the risks? (Even though vaccines are not technically vegan.)

    • shayneo

      No. The amount of methylmercury in vaccines is so low the harm can’t even be calculated. There have been plenty of studies and no evidence of harm has been found.

      Mercury is always a concern and has to be balanced against the benefit. You can insist on getting immunizations from a single dose vial. The single dose vial do not need to have a preservative in them.

    isn’t an injected mercury meaningfully more toxic than mercury eaten in fish? Doesn’t every dose of mercury accumulate in the body?

    • http://www.DonForresterMD.com/ Don Forrester MD

      No. It has to do with the dose. Organic mercury is very well absorbed by the GI tract. The amount of injected mercury has to be compared to the amount in food such as fish. Also consuming fish which is the greatest source of mercury in the diet comes along with other contaminants such as dioxin, insecticides and even drugs. You might view videos on fish to see the extent of this problem. Mercury is best avoided.

    Hi Doc,

    I was just wondering if you exercise any scientific skepticism when reading the literature for your videos? Do you wait a little while to see what comes out of the post-publication review of the articles? Just because there is a single study with a certain result does not mean that it reflects the direction of the literature. Just curious as to what methods you use.

    Hi Doc

    I was just reading about thimerosal. The mercury in thimerosal is an inorganic ethyl mercury as opposed to the methyl mercury in tuna. Isn’t ethyl mercury processed more easily by the body. If that is the case, is it even fair to compare thimerosal and tuna?
