Healthy Unhealthy Foods and
The Dangers of Soy

Healthy Unhealthy Foods is about the dangers of soy which has been heavily promoted as a health food by the vegan community in particular.

Improperly treated soy contains high amounts of Trypsin Inhibitors.  Trypsin inhibitors as well as goitrogens are a couple of the anti-nutrients found in soybeans.

Soy and estrogen is another one of the heated debates on whether or not you should eat this legume.

The dangers of soy are quite controversial and some people believe that this is a health food and then there are others that wouldn't touch soy with a ten foot pole.

Interesting Facts About the Soybean

The soybean originates from China and then spread to Japan and other countries.  It arrived in America some 150 or so years ago and was grown to feed livestock.

America is now the largest producer of healthy unhealthy foods such as soybeans - and that's in the entire world!

Soy beans were not considered fit for human consumption until the Chinese learned to ferment them, which makes them digestible.

Fermented soybean products available in Asia and America include Natto, Miso, Soy Sauce, and Tempeh.

The Japanese and Chinese may only eat about two teaspoons of soy per day.  Again that's 2 teaspoons (not tablespoons) of fermented soy!

Unfermented soy is one of the foods responsible for a majority of food allergies and it is also a food most commonly associated with food allergies in children.

People with a soy allergy or soy intolerance can suffer everything from hives to breathing difficulties upon eating this healthy unhealthy food.

Trypsin Inhibitors

Soy is actually considered a complete protein food, but it is rich in trypsin inhibitors which block the action of trypsin.

Trypsin is a digestive enzyme that we need to properly digest protein.  Without trypsin, you’ll soon experience serious gastric problems including stomach cramps, diarrhea, and bleeding.

And without trypsin, you'll also experience reduced protein digestion and deficiencies of amino acids.  And this will put an enormous stress on your pancreas.

Trypsin inhibitors are considered growth inhibitors and are not completely deactivated during cooking.


Goitrogens are substances that depress your thyroid function.  They are found in soy and in vegetables such as kale and cabbage.

Goitrogens work by preventing your thyroid from getting enough iodine which is an essential nutrient for your thyroid gland.

Your thyroid gland is very connected to your metabolism, your mood, energy level, memory, circulation, body temperature, and your immune system.

One of the Huge Dangers of Soy

Soybeans are high in phytic acid, which is present in the bran of the soybean.  They are naturally present in all grains, seeds, nuts, and legumes.

Phytic acid or phytates can block the uptake of essential minerals such calcium, magnesium, copper, iron and especially zinc in your intestinal tract.

Scientists in general agree that diets high in phytic acid contribute to widespread mineral deficiencies in third world countries.

This healthy unhealthy food has one of the highest phytic acid levels!

The phytic acid in soy are highly resistant to normal phytic acid reducing techniques and only a long period of fermentation will significantly reduce the phytic acid content found in soybeans.

Vegetarians and Vegans who consume tofu as a substitute for meat and dairy products may be risking severe mineral and protein deficiencies.

When consuming soy you should stick to fermented soybean products like Natto, Miso, Tempeh, or Naturally Fermented Soy Sauce.

Soy and Estrogen

Phytoestrogens are found in plant foods such as beans, seeds, and grains.

Soy is higher in phytoestrogens called isoflavones than just about any other food source on the planet.

Phytoestrogens are plant based estrogens that copy estrogen in our bodies and may either have the same effect as estrogen or block estrogen.

Apparently the soy industry has been very busy publishing studies which indicate phytoestrogens are good for you.

However, independent research has shown that consuming excess isoflavone phytoestrogens may actually do your body more harm than good.

What's really scary is that infant soy formulas contain a very high amount of these phytoestrogens.  And isoflavone phytoestrogens have been linked to infertility and thyroid problems.

Healthy unhealthy foods such as unfermented soy have no real history of consumption and so the question becomes....."Do you want to be the guinea pig?".
