Soy phytoestrogens that bind oestrogen receptors far more weakly than oestradiol and with a preference for the beta receptor. Only some people harbour the gut bacteria that produce the metabolite equol.
4 foods, grouped by presence band. Bands are used instead of amounts because compound content swings widely with cultivar, soil, storage and preparation — a single number per food would look more precise than the measurements justify.
One of the compounds this food is characterised by in the literature.
Consistently reported in this food in amounts researchers treat as meaningful.
