Soya products have been promoted as a wonder food and one we should all be eating every day. However, if you look at the old cultures that have included soya in their every day diet you will find that they only soya they eat is fermented. And for good reason. The anti nutrients are destroyed if the beans are fermented. In simplistic terms eating non-fermented soya products uses more nutrients than your body gains. The hormone mimicking effects are best avoided too.
