News: Debunking Iodized Salt
The Iodized Salt Scam, a Three Part Deception
By Lynne Farrow
From The Iodine Crisis: What You Don’t Know About Iodine Can Wreck Your Life
Do you get enough iodine from your iodized salt? Does your iodized salt
contain any iodine at all?
We have an iodine crisis in good part because of the iodized salt scam.
The outdated government recommendation (RDA) states that an
adequate amount of iodine can be consumed from less than the 250
mcg supposedly contained in a half teaspoon of iodized salt. But they
never factored in current bromide pollution purges iodine.
They never factored in that iodine “evaporates” from salt containers. Or
that the form of iodine in salt doesn’t absorb well. The myth that you can
get enough iodine from iodized salt has now been debunked by
So, how much iodine do you absorb from iodized salt?
No one really knows, because misleading information has created a
three-part information scam. Whistle-blowers must challenge the
current government iodine guidelines because they’re based on
inaccurate information and disproved assumptions that are harmful. The
report, Iodine Nutrition: Iodine Content of US Salt by Dasgupta et al,
discusses the “Iodine Gap.”
The gap refers to the amount of iodine that’s supposed to be in iodized
salt and what amount can actually be measured by the time you use it.
The researchers also point out that salt is a poor food product to fortify
because chloride which is a halogen, competes with the iodine, making it
Scam 1. The average gram of iodized salt is thought to contain
0.075 mcg. But that measurement is taken at the factory. By the time
the salt reaches the grocery store half of the iodine in the sealed
container has “vaporized,” or as scientists would say, the salt “sublimed”
into the air. Once you get the salt container to your kitchen and open it,
whoosh, more iodine escapes. The longer you keep it, the less iodine
remains. Iodine in salt is unstable. Dasgupta et al. report it takes
between 20 and 40 days for an opened container of iodized salt to lose
half of its iodine. How long have you had that iodized salt in your pantry?
So when you factor in the loss of iodine into the air, the actual
consumption of iodine through salt is completely theoretical, and the
figure based on the factory number, the amount the people at Morton
add to the product, is not what we actually get when we sprinkle iodized
salt on our food. Do the math. The bottom line is, nobody knows how
much iodine you get from iodized salt. There are too many variables.
Was the salt warehoused? Do you live in a damp or warm area? How
long has it been in your cupboard leaking iodine fumes into the universe?
Scam 2. But say you’re an average man, standing outside the
Morton factory and get the freshest, most iodized salt available. What
are you getting? Even the most concentrated iodized salt is only 10
percent “bioavailable,” meaning only a fraction gets absorbed. Iodide
may be added to salt but remember, salt is sodium chloride. Chloride
and iodide are both in the halogen family of elements so they compete
with each other for the same receptors. Chloride has the ability to
cancel out at least some of the benefit of iodide.
Again, do the math. You’re only absorbing 10 percent of whatever the
good people at Morton put in the container. Unlike adding iodine to flour
as potassium iodate, the iodine in salt is difficult to absorb. You certainly
may get some iodine from iodized salt but what goes in doesn’t
necessarily get to the right places.
Scam 3. But say you’re a woman standing outside the factory
and get the freshest salt which is only 10 percent bioavailable, you’re
might get a protective amount, right? A protective amount if, say, if you
consumed a pound a day?
No. Not if you’re a woman. The salt is iodized with potassium iodide
which may be helpful to the thyroid. But the breasts and ovaries need
iodine as well as iodide. This time, you can skip the math and just go
straight to the science. Women are taking the wrong iodine.
Is there ever any reason to consume processed iodized salts in this time
of Iodine Crisis?
The answer is:
1. Only in an emergency when you need salt and can’t access
2. Only if you can’t afford iodine supplementation.
Taking iodized salt alone as a source of iodine actually only benefits
communities too poor to get any other kind of iodine. In the US,
iodizing salt was meant to prevent goiter but nothing else. The
minimal iodized salt standard, is in fact, the “Goiter Standard,” but
does not reflect the needs of the other organs. The Goiter Standard
of iodine provides a disappointingly low bar for the government to
set when iodine helps prevent so many other illnesses.
Skimping on the cheap cost of iodine supplementation means paying for
more expensive problems down the line. Another thing to remember is
that processed salts often come with controversial aluminum anti-caking
chemicals. I wouldn’t take aluminum-laced processed salt products
unless I had a lot of cash socked away for future Alzheimer’s care.
