Kelp and toxins, hair loss?
enart.cankaoziliao.comI have been reading that iodine is a key nutrient that has been shown to be helpful with thyroid problems and regulating metabolism, and a lack of iodine can contribute to weightgain, low energy, etc. Most of these articles list kelp as an excellent source of iodine, however, when I have taken it before, I had problems with hairloss and some other minor symptoms. I have done a little research and found that some kelp, depending on how it is processed, contains highly toxic contaminants like arsenic (!!). The article about this is as follows:
Thrombocytopenia Causes:
Toxic Chemicals:
Exposure to toxic chemicals, such as pesticides, arsenic, and benzene, can slow the production of platelets
It is noted that kelp can concentrate heavy metals, and that some kelp preparations contain substantial levels of arsenic. It has been noted that urinary arsenic excretion in patients with peripheral neuropathy, who have been taking kelp tablets, has increased, and seaweed ingestion has been linked with chronic thyroiditis. Arsenic intoxication can cause bone marrow depression and megaloblastic changes. Physicians need to be aware of the potential dangers of contaminants in some kelp preparations.[Severe Dyserythropoiesis and Autoimmune Thrombocytopenia Associated With Ingestion of Kelp Supplements, Pye, Kathryn G., et al, The Lancet, June 20, 1992;339:1540]
My question is, has anyone else experienced these sorts of symptoms with kelp ingestion? And also, are other seaweeds, such as Nori and Wakame, also potentially harmful? What are some other sources of iodine (other than iodonized salt, as I prefer to use seasalt)?
Technically, any sort of seaweed could be harmful and/or contaminated, but it would only be low quality companies that would have contaminated products. If you're concerned about contamination, just make sure the company has a good rating with either the GMP (Good Manufacturing Practices) or USP (U.S. Pharmacopoeia), as those are the main quality assurance organizations (USP is for the U.S., GMP is for the U.S. and worldwide).
Honestly, most Americans actually get several times the RDA of Iodine because the typical American diet has so many processed foods, which typically have Iodized Salt in them. If you eat even a few processed foods every day (pre-packaged foods, chips, cookies, crackers, and most other snack foods), you probably get more than enough Iodine. Good luck!
BTW sea salt does not contain iodine
one suggestion was to use iodine on, say your upper thigh each day until you no longer see the color of it as it is absorbed in the skin; when you have enough it won't absorb any more~you can get iodine at your pharmacy (the brown kind so you can see the results)
another source of iodine is Spirulina or Chlorella
