b b,

In their 2006 paper, Estimated Asian adult soy protein and isoflavone intakes, Messina et al. found a much higher intake of isoflavones among the Japanese population, up to 100 mg per day. I review their findings in my more extensive article, Soy Part 2: Research. Messina generally assumes that a serving of soy has 25 mg of isoflavones, although I’m not sure if I know that from the paper or from personal correspondence as I didn’t do a very good job of documenting that in my article unfortunately.

“A 2011 clinical trial found that 16 mg/day of isoflavones in people with mild hypothyroidism appeared to cause an increased rate of advancing to overt hypothyroidism (33).”
I wondered if anyone is likely to get that much in an average vegan diet. At https://pubmed.ncbi.nlm.nih.gov/8655094/ I saw this quote about the average diet in Japan: “On the basis of these data for average annual consumption of soybeans and related products, daily intake of genistein and genistin by the Japanese is calculated to be 1.5-4.1 and 6.3-8.3 mg/person, respectively.”
