Soy
Yes, I have started making soy shakes, with today being my 2nd day. And
I can tell you, my body is not right with it. Also, I have added
nutritional yeast, so it could be the soy, the yeast, or both. Plus, I
am using tofu and also soy protein powder. So it could be either or
both. I do notice that the soy protein affects me more negatively than
the tofu.
And then I read that beef interferes with absorption of calcium? That is
one good reason to have soy - protein and calcium. What is a person to
do????? Pam and going crazy!!!!

You can have 25g (30g+ makes you hypothyroid) of soy each day.

The following article was in the AOL news. It’s a little long and I know it
goes counter to much of the ER4YT information but, frankly, soy scares me
because it permeates so many food products these days and is ingested
regularly by the population. It’s in many processed foods just like wheat,
corn, and complex carbohydrates. I think that the future may well bear out
the claims that the 3 isoflavones found in soy that mimic estrogen may
contribute to the cause for premature growth in our children, chonic illness
in our population, and the general depression of our minds, as well as, our
immune systems.
I apologize for the length of this post but felt compelled to share my worry.

Soy Formulas May Weaken Immune System
By Salynn Boyles
WebMd
(May 20) — Fifteen percent of infants in the U.S. are fed soy-based
formulas, and millions of women take soy supplements to ease the symptoms of
menopause. Now, new animal research suggests a component of these products
just may weaken the immune system.
Mice fed the component genistein at lower levels than those found in infant
soy formulas showed large decreases in two key markers of immune function.
But researchers say more study is needed to determine if soy formulas and
supplements really do depress immune response in people.
“We are not trying to be alarmist here, and we aren’t suggesting that these
products have a huge impact on the immune system in humans,” study author
Paul S. Cooke, PhD, tells WebMD. “But this is the first direct evidence that
soy produces these immune effects. And it suggests that this is something
people need to be cautious about.”
Genistein is the most prominent of three isoflavones found in soy.
Isoflavones mimic the effect of the hormone estrogen, which is a known immune
system suppressor. In earlier studies, Cooke and colleagues at the University
of Illinois in Urbana saw a dramatic reduction in the size of the immune
system organ called the thymus in mice injected with genistein. Immune
function is largely determined by the thymus, which is involved in the
development of immune system cells.
In this study, the researchers examined immune system effects in mice fed
diets high in the isoflavone. At levels similar to those found in soy-fed
infants, genistein appeared to produce a large decrease in thymus size and
immune cell function. The findings were published in the May 28 issue of the
Proceedings of the National Academy of Sciences.
The study appears to contradict recently published research, sponsored by a
soy formula manufacturer, suggesting that infants fed soy-based diets have
normal immune development as measured by response to routine childhood
immunizations. Infants fed soy-based formulas also demonstrated immune status
similar to infants who were breastfed.
But a Danish study assessing soy supplementation in postmenopausal women did
find evidence of immune suppression. In that study, published last year,
women who took standard doses of a synthetically derived soy supplement
routinely experienced a decrease in disease-fighting white blood cells called
lymphocytes. Lymphocyte counts returned to normal in most women after they
stopped taking the supplement.
“There have been very few studies looking at soy products and immune
function, and the studies that have been done are mixed,” Cooke says. “At the
very least, I think we need to take a closer look at immune function in
adults fed soy-based formulas as children.”
But pediatric nutrition expert Fima Lifshitz, MD, tells WebMD that there is
no epidemiological evidence linking soy formulas with impaired immune
function. He adds that most evidence suggests that babies fed soy-based diets
develop normally. Lifshitz is a member of the American Academy of Pediatrics’
nutrition committee and is the chief of nutrition sciences at Miami
Children’s Hospital.
“We all believe that mother’s milk is the best thing for babies, and cow’s
milk-based formulas are my second choice because they are closer to mother’s
milk,” he says. “But there is no evidence that people given soy formula as
infants have any different outcome than those given milk-based formulas.
Many, many people have grown up healthy on these formulas.”

The soy issue is confusing like many of the other topics. You have to read
the articles and studies and decide for yourself. Soy comes with toxins. If
the toxins are removed then the soy is less dangerous. Soy is far better for
type As than Os. I find that dairy cream or heavy cream is much better for me
to use than soy milk. I don’t use it very often but do when I need milk in a
recipe.

Since I am awaiting my copy of LR4YBT, I am going by Christiano’s book.
Someone mentioned that soy is not a great thing for either a secretor or
non-secretor. Please elaborate on the soy thing. Thanks to Thomas who sent
me the description of secretor.
Thanks so much,
Joy
