The above study was reported by Roy Walford, M.D., in his book, "Beyond The 120 Year Diet". Walford was considered to be an expert in the field of gerontology. He didn't mention who did the study but said he thought it was a well done study. I don't think he was biased because he also mentioned a lot of good things about soy.

That study is pretty old and no one else followed up with similar studies, so I take it with a grain of
sea salt

Soy products – What about soy products?
Soy products are 40% fat and most of them are highly processed. An excess of soy protein may stimulate insulin growth factor, which is a tumor promoter.
Eat soy products cautiously.
So it's ok, but not everyday and just read the label.
