Soya, Oestrogen, Cows’ Milk and WAPF-Logic-Fail

9 November 2014 at 19:46 (Plastic Vegan, Random Randomness) (, , , , , )

The folks at WAPF are always good for a laugh. If you’re interested in vegan nutrition, you’re bound to have come across this claim at some point:

The most serious problem with soy may be its use in infant formulas. “The amount of phytoestrogens that are in a day’s worth of soy infant formula equals 5 birth control pills,” says Mike Fitzpatrick, a New Zealand toxicologist. Fitzpatrick and other scientists believe that infant exposure to high amounts of phytoestrogens is associated with early puberty in girls and retarded physical maturation in boys.

What I find incredibly amusing about claims like this is that the people who love to throw out this “fact” are the same ones pushing milk.

Now let’s just get one thing straight. Soya comes from a plant. Plants are not female mammals.

I’m gonna say that again.

Plants are NOT female mammals.

Therefore, they do not produce oestrogen. They don’t. They just don’t.

Now let’s think of an animal that does produce oestrogen. Hmm, let me think. Oh yeah! Cows! Cows produce oestrogen!

Now here is an extract from a very interesting article I came across the other day (emphases are my own):

The potential for risk is large. Natural estrogens are up to 100,000 times more potent than their environmental counterparts, such as the estrogen-like compounds in pesticides.

“Among the routes of human exposure to estrogens, we are mostly concerned about cow’s milk, which contains considerable amounts of female sex hormones,” Ganmaa told her audience. Dairy, she added, accounts for 60 percent to 80 percent of estrogens consumed.

Part of the problem seems to be milk from modern dairy farms, where cows are milked about 300 days a year. For much of that time, the cows are pregnant. The later in pregnancy a cow is, the more hormones appear in her milk.

Milk from a cow in the late stage of pregnancy contains up to 33 times as much of a signature estrogen compound (estrone sulfate) than milk from a non-pregnant cow.

In a study of modern milk in Japan, Ganmaa found that it contained 10 times more progesterone, another hormone, than raw milk from Mongolia.

In traditional herding societies like Mongolia, cows are milked for human consumption only five months a year, said Ganmaa, and, if pregnant, only in the early stages. Consequently, levels of hormones in the milk are much lower.

“The milk we drink today is quite unlike the milk our ancestors were drinking without apparent harm for 2,000 years”, she said. “The milk we drink today may not be nature’s perfect food.”

Earlier studies bear out Ganmaa’s hypothesis that eating dairy heightens the risk of some cancers.

One study compared diet and cancer rates in 42 countries. It showed that milk and cheese consumption are strongly correlated to the incidence of testicular cancer among men ages 20 to 39. Rates were highest in places like Switzerland and Denmark, where cheese is a national food, and lowest in Algeria and other countries where dairy is not so widely consumed.

Cancer rates linked to dairy can change quickly, said Ganmaa. In the past 50 years in Japan, she said, rising rates of dairy consumption are linked with rising death rates from prostate cancer – from near zero per 100,000 five decades ago to 7 per 100,000 today.

Butter, meat, eggs, milk, and cheese are implicated in higher rates of hormone-dependent cancers in general, she said. Breast cancer has been linked particularly to consumption of milk and cheese.

Stick that in your cheezburger and smoke it, Wapftards.

And now, a bit more commentary, from Yahoo Answers, because they make the point better than I do.
Full thread:

There are massively more amounts of men with moobs in the West than the Middle and Far East. The general population in the West drink cows milk – in the Middle and Far East it’s soy milk.
Thus, it must be a fact that cows milk, which of course has oestrogen in it, is the absolute cause of the moob epidemic. The dairy industry must know this. Maybe they should advertise this fact.

But no, they want everyone to believe that it’s actually soy that is the problem.
Hoping that people don’t realise that the cows that provide their milk are fed with soy – so, if soy really “IS” the big deal then why do the feed their cows it?

If soy milk makes your libido drop so much then explain why over in other parts of the world where they have been drinking it for up to thousands of years they have MUCH HIGHER BIRTHRATES THAN US IN THE WEST.

Did you all notice how the Dr in the story was “excited!” when he discovered the guy drank soy?
Perhaps he was already an anti-soy, anti-veg*n hater, and thought “finally I have EVIDENCE to beat all those hippies over the head with”. He probably is right though, maybe (even though I have not seen any side effects myself, having drank soy for around 13 years) I should go back to drinking cows milk and vastly increase my risk of osteoporosis and cancer.

Cancer you say? Well, to counter the Soy Is Bad For You post that was on a website, how about this one :

Yup, and that has also been published and is recognized by scientists.

So, waddya do?

Edit : other foods that also allegedly boost oestrogen levels include : soy beans, chick peas, cereal bran, vegetables, legumes and fruits.

Why aren’t people concerned about eating chick peas, bran, vegetables, legumes (beans, peas and lentils) and fruit?

Ah wait, Omnis generally eat those things quite a lot too, so best not demonize those foods as it’s the veggies we’re attacking!

IF it has any effect, it’s on estrogen. That guy who talked all about phytoestrogens and soy is the only one here who really knows what he’s talking about. Part of the confusion lies in that phytoestrogens are far less strong than the animal estrogens that are in our bodies. So the phytoestrogens may not ADD to our overall estrogen, but rather compete with it for the same hormone receptors. But because it’s weaker, it has less of an effect.

In the case of women in menopause, who have very little estrogen, the weak estrogens in soy will make a noticeable difference in giving you more estrogen. But in the case of young fertile women who have lots of powerful estrogens, soy estrogens will take the place of some of the animal estrogens in your tissues, and therefore have an almost imperceptible, but slightly weakening effect.

Likewise, in young healthy men, soy won’t have a huge effect on them because there are too many androgens, and the androgens cancel out any weak effects of soy. But an older man whose hormones have dropped a lot might find that phytoestrogens have enough of an effect given their overall lower hormone levels, that they have problems.

So if your argument against soya is the phytoestrogens, you’d do well to not extol the benefits of cows’ milk in the next sentence. Just saying.
