Life Extension article on iodine

Here’s a link to my recent article in Life Extension Magazine on iodine:

Halt on Salt Sparks Iodine Deficiency

Iodized salt, a concept introduced into the U.S. by the FDA in 1924, slowly eliminated goiter (enlarged thyroid glands), along with an enormous amount of thyroid disease, heart attack, mental impairment, and death. The simple addition of iodine to salt ensured that salt-using Americans obtained enough iodine sufficient to not have a goiter.

Now that the FDA, goiters long forgotten from their memories, urges Americans to reduce salt, what has happened to our iodine?

I talk at length about this issue in the Life Extension article.

    Dr Davis:

    My question is on a bit of a tangent to this topic, but on the related issue of what seems to be a situation where maintaining what was considered a "healthy" level now is possibly dangerous:

    "Low triglycerides are risk factor for hemorrhagic stroke"

    http://www.lipidsonline.org/news/article.cfm?aid=8578

    Do you have any insight into this study ? I have been diligently keeping my lipid levels in check .I lowered my triglycerides from a fairly low level of 75mg/dL down to 50 mg/dL. Now I am concerned. (My LDL is 95 mg/dL and HDL is 64 mg/dL). I don't take any drugs , just lots of exercise and diet (Krill oil, almonds, Beta Glucan fiber)

    Thanks

    Thanks

    Hi, Future–

    That is the frustration with iodine: insufficient data on what represents an ideal level of intake. And it may vary from region to region, individual to individual.

    The T3 issue is indeed fascinating, a topic that will be explored more fully in the blog and in the Track Your Plaque website.

    Hi, Runner–

    I'm skeptical that this is an important effect that warrants action.

    Primitive cultures typically have triglycerides in very low ranges, since they avoid processed foods. I'd be shocked if achieving physiologic normal levels is the sole explanation behind increased stroke.
