Teff, maybe. It is at least gluten free.
I tried to find info on estrogens, if any, that are in teff. I found that white teff has very different flavones than brown teff. Red teff has different than either white or brown. And which flavones are in each. A side note is the flavone differences are not influenced by where it is grown - that is significant.
Anyway, I found that estrogens are in flavones. But I did not find whether all flavones are estrogens or all estrogen us in the flavones. Or which flavones have more, less, or different estrogens.
The picture has the title and authors of the paper with the flavones in each white and brown teff.
