Soy has a mixed reputation of being good and bad. One important area of discussion is the allergy potential of soy. In it’s unfermented form, soy is hyper-allergenic, due to the harsh proteins contained within. Once fermented the allergy causing proteins are broken down creating a hypo-allergenic food that is rich in bio-available nutrients.

Body Ecology best explains this area of debate, and the studies below provide the evidence to support this.


How fermenting takes the ‘allergy’ out of soy and other foods.
