Peanuts and cashews hinder iodine uptake

November 9, 2018

 

[Please read the information in the previous post on soy.] 

 

For those who may be experiencing the negative effects of low iodine levels and diminished thyroid function (e.g., sluggish metabolism, infertility, low energy, and so much more that may be linked), it is important to know the various, so-called "foods" that hinder the uptake of iodine, etc. 

 

For example, in men, this information can help lead to healthy testosterone levels. Many people may be eating what appears to be a "healthy" diet, and yet they may be unwittingly blocking the little iodine that they are ingesting. They may have already noted a loss of energy, etc., upon eating certain "foods," and didn't know why.

 

I personally avoid cashews, since they have the same substance that causes the poison ivy rash. 
 

I have tried to appreciate peanut butter, peanuts, etc. (organic, of course). Yet, peanuts/peanut butter never "delivered" the punch. There always seemed to be something wrong. This is subjective. But it just may be that they were blocking some necessary iodine that my body needed. How important this is for everyone, especially children, who need healthy iodine uptake to grow and thrive.

 

Notice carefully the following research quotes:

 

“It has been shown experimentally that peanut seeds inhibit the iodine uptake by humans (Greer and Asherwood 1948). Such inhibition leads to a deficiency of iodine in the thyroid, eventually producing goiter…The goitrogenic effect of peanut meal can be effectively counteracted by iodine supplementation, but not by heat treatments.”
(World Oilseeds, 1992)

 

“Legume goiter is induced by goitrogens in legumes like soybeans and peanuts…Legume goiter can be treated by iodine therapy.”
(CRC Desk Reference for Nutrition, 1997) 

 

Iodine deficiency and its association with intelligence quotient in schoolchildren from Colima, Mexico…The main goitrogenic foods consumed were peanuts…”
(Public Health Nutr. 2008)

 

“Two papers…(J. Nutrition, 61, 87, 97 (1957)) provide concrete evidence for the existence of a goitrogenic agent in the groundnut (peanut, Arachis hypogaea).”
(Nutrition Reviews, Volume 16, Issue 1, 1 January 1958)

 

“The red skin covering peanuts (Arachis hypogaea L.) contains a glycoside that is goitrogenic.”
(L. P. Reitz, Breeding for Safety in Field Crop)

 


“Preliminary studies…revealed that a peanut meal containing a higher proportion of the red skin was more goitrogenic than depigmented meal.”
(Eduardo Gaitain, Environmental Goitrogenesis)

“These results thus provide confirmatory evidence for the hypothesis that arachidoside [from the skin of peanuts] is goitrogenic by virtue of its capacity to interfere with the organic binding of iodine…”
(N. R. Moudgal, E. Raghupathy, P. S. Sabma, 1958)

“…It is also seen…that anacardioside [from the skin of cashews] inhibits the organic binding of iodine as well…”
(N. R. Moudgal, E. Raghupathy, P. S. Sabma, 1958)

“The inclusion of arachidoside and anacardioside, the pigments isolated from the outer skin-covering of groundnuts [peanuts] and cashew-nuts respectively, in the diet of rats, at a level of 20 mg per rat per day for 7 weeks results in goitre. Incorporation of potassium iodide in the diet counteracts partially the goitrogenic action…”
(N. R. Moudgal, E. Raghupathy, P. S. Sabma, 1958)


 

It appears, in some studies, that supplementing with extra iodine counters, to some degree, the goitrogenic effect of peanuts and cashews (as does not consuming the skins). 
 

 

Organic peanut butter can be expensive. And it is often filled with cane sugar. Peanut butter that is not organic often contains high amounts of toxic, cancer-causing pesticides (see, https://robynobrien.com/food-allergies-the-hidden-truth-about-peanuts/)

 

Families that use lots of peanut butter every week are endangering their children when they don't buy organic. On top of this, the peanut butter may be hindering a considerable amount of much-needed iodine in the body, leading to sluggishness, lack of attention, hindered learning, and much more.

 

Often, the so-called "American tradition," is deadly or harmful. For a time, artery-clogging Crisco and margarine were as "American" as apple pie (and in the apple pie!).
