A couple of months ago, this title was linked to an article in menshealth. This got the discussion off to a bad start. Here is a better link to a paper published in 2012:
The study was not small, the first sentence of results reading
"In the incidence analysis, we observed 695 lethal prostate cancers during 879,627 person-years. Men in the highest quintile of choline intake had a 70% increased risk of lethal prostate cancer."
Several papers are referenced in a video
Choline is high in eggs, also red meat and poultry.
What do our experts think of these studies? I've already given up most red meat (dairy, etc). Must I now give up eggs and poultry as well, which we eat a lot in our household?
