◥◥◥◥Fermented vs. Unfermented◥◥◥◥

Unfermented soy is not the health food it's purported to be. In fact, in 2002, the British government's expert committee on the toxicity of food (CoT) published the results of its inquiry into the safety of plant estrogens (or phyto-estrogens), mainly from soya proteins, in modern food.

Their experiments and other studies have found that soy contains toxins and plant estrogens that could disrupt women's menstrual cycles, stimulate the progression of breast cancer, damage the thyroid, lower testosterone levels and have uncertain effects on the prostate.

From a digestive perspective, soy beans, like other legumes, consist of protein and starch, making them difficult to disgest, especially when stomach acid is low. Fermenting soyfoods can reduce their harmful effects.

Unfermented soybeans contain potent anti-nutrients

In their natural form, soybeans contain phytochemicals with toxic effects on the human body. The three major anti-nutrients are phytates, enzyme inhibitors and goitrogens.

These anti-nutrients are the way nature protects the soybean plant so that it can live long enough to effectively reproduce. They function as the immune system of the plant, offering protection from the radiation of the sun, and from invasion by bacteria, viruses, or fungi. They make the soybean plant unappetizing to foraging animals. All plants have some anti-nutrient properties, but the soybean plant is especially rich in these chemicals. If they are not removed by extensive preparation such as fermentation or soaking, soybeans are one of the worst foods a person can eat.

Unfermented soy has been linked to digestive distress, immune system breakdown, PMS, endometriosis, reproductive problems for men and women, allergies, ADD and ADHD, higher risk of heart disease and cancer, malnutrition, and loss of libido.

Groups most at risk of experiencing negative effects from the anti-nutrient properties of soy are infants taking soy baby formula, vegetarians eating a high soy diet, and mid-life women going heavy on the soy foods thinking they will help with symptoms of menopause.

Soybeans contain high levels of phytates

All legumes contain phytate (also known as phytic acid) to some extent, but the soybean is particularly rich in this anti-nutrient. Phytate works in the gastrointestinal tract to tightly bind minerals such as zinc, copper, iron, magnesium and calcium. It has a particularly strong affinity for zinc, a mineral that supports wound healing, protein synthesis, reproductive health, nerve function, and brain development. It is believed that people living in developing countries are shorter than those in developed countries because of zinc deficiency caused by eating too many legumes. There is also evidence that mental development can be negatively impacted by a diet high in phytate.

In most legumes such as other varieties of beans, soaking is enough to break down most of the phytate content. However the soybean requires that the enzymes be released in the fermentation process to reduce its phytate content to the point where it becomes fit for consumption. This means that fermented soy foods like miso and tempeh have the lowest levels of phytate and are the best choices for anyone wishing to eat soybean products. Tofu is also a good choice, as long as care is taken to replenish loss nutrients.

Whole soybeans, soy milk, soy chips, soy protein isolates, soy flour and all the other myriad of products made from processed soybeans and advertised as health foods have much higher levels of phytate and are not worth eating.

Unfermented soy products are rich in enzyme inhibitors

When food is eaten, digestive enzymes such as amylase lipase and protease are secreted into the digestive tract to help break it down and free nutrients for assimilation into the body. The high content of enzyme inhibitors in unfermented soybeans interferes with this process and makes carbohydrates and proteins from soybeans impossible to completely digest. When foods are not completely digested because of enzyme inhibitors, bacteria in the large intestine try to do the job, and this can cause discomfort, bloating, and embarrassment. Anyone with naturally low levels of digestive enzymes such as elderly people would suffer the most from the enzyme inhibiting action of soy.
