Unspoken details about Soy

Tuesday, February 3rd, 2009

Soy protein is a perfect example for something worldwide accepted as a miracle, but next day tagged as harmful.


In recent years, soy has had a phenomenal increase in popularity, as being the most well-known risk free protein sources available. Reasons? it’s cheap, and has a ton of uses: it can be used in cereals, breads, tofu, protein powders, candies.

But what most people don’t know is that soy could also be harming you.

Basically, soy’s negative aspects originate from two of its isoflavones: daidzein and genistein. These two can very easily get attached to estrogen receptors, which come in two types: beta and alpha. The alpha type receptors are associated with increased levels of water retention, body fat.

This doesn’t sound terrible at all, at least not yet. The drastic effct that soy has on the body is characterized by suppressing the male type hormone - testosterone. Recent studies have clearly shown that there is an undeniable link even between short term soy protein consumption and 76% reduced testosterone levels. Rest assured, this will cause no permanent damage, as testosterone levels go back up after you’ve stopped ingesting soy protein. But what happens in the meantime is that with the testosterone hormone being suppressed, estrogen will now be the more prevalent one. This is when things will start to go bad, especially for males.

It is also believed that the effects that pytoestrogens found in soy induce might have been terribly underestimated for the past decades.

And that’s just the tip of the iceberg. This is not serious problem for men alone. Pregnant women will also be strongly affected by this.


When testing on rats, female rats were fed levels of genistein equal to those which humans on a soy diet ingest. It was found that the rats’ offspring weighed far less. When genistein was given to male rats, their production of sperm greatly decreased, and so did their body weight along with their testicle size. It was found that genistein may also reduce the urge of mating and reproducing.

Another huge problem for guys is that there is some quantity of evidence that the dangerous duo of genistein and isoflavones can facilitate the development of cancer cells in the prostate.
Soy must be thoroughly researched and not taken as a miracle. It’s a part of the food industry, a billions of dollars capitalism driven industry. And soy, its new star, is dirt cheap to produce.

Soy allergies

Tuesday, February 3rd, 2009

Upon hearing the term “soy allergy”, one might presume this isn’t such a fierce allergy. To prevent this allergy from triggering you might think it’s enough to stay away from soy, or soy products in general. But what you don’t actually know is more foods than you might think contain soy.

Soy is found in foods such as: grits, flour, some dried or even green beans, curd tofu cheese, soy milk, vegetable oils, soy sauces. And it doesn’t end here; soy isn’t always easy to find on the food’s list of ingredients. Sometimes it’s hidden, being listed as an additive that’s used for flavoring, or maybe a protein that’s added as a meat substitute.

Some products made of soy will cause one person an allergic reaction, and simply nothing to another person. Some products made of fermented soy are safe from causing any allergic reactions to anyone. Despite some people being allergic to soy, they will only experience a reaction when consuming a product made from whole soy beans.

With soy sometimes being hidden from the list of ingredients, it can be reasonably hard for someone to pinpoint if he or she is allergic to the particular product before consuming it. Thus, it is helpful to know what the symptoms that may occur in case you’re allergic are.

Soy allergies are quite different than other more common allergies. You won’t begin itching all of a sudden or having hives like you would when ingesting other allergic products. An allergy to soy starts to develop in your immune system. Once soy is ingested, the immune system will mistake soy for something that’s likely to harm the body. Next time it’s ingested, the immune system is going to attack to protect itself. This is done by ordering the creation of antibodies. The antibodies are going to be producing many chemicals, among which histamines. This is when the body will start experiencing signs of an allergic reaction. This can happen in a number of ways.

A response to ingesting soy can pop up in the gastrointestinal tract, respiratory system, skin, or even in the cardiovascular system.

The following symptoms can develop: asthma, acne, fever, dermatitis, vomiting, itching, diarrhea – these are just a few! In fact, these reactions could get worse every time an allergic product is ingested.
The reason ? The immune system will produce more and more antibodies each time soy enters the body.

Also, there is always the problem of other products being cross reactive. Simply put, if you are allergic to soy, you’re also likely to have an allergy to: peanuts, chick peas, green peas, lima beans, wheat, string beans, barley, rye, along with any other products containing these substances.

If you think you might be allergic to soy, best way of checking is staying away from any soy products for a couple of days, giving time for any soy products to leave your body. After this, ingest a small amount of the product in question and check to see if any symptoms return.
