We know non-fermented soy is best avoided (to put it mildly). But what about smallish or trace amounts of soy products in some foods?
Specifically I'm wondering about soy lecithin used in dark chocolate.
In the 85% chocolate that I buy, it is usually listed as the last or penultimate ingredient (just before vanilla). I don't know what the actual amounts used are, and whether in these amounts it would have any of the harmful hormonal effects of soy if consumed fairly regularly (say, two 100g chocolate tablets a month).
