DY: From the article:
What do you think they would find if they did a study regarding eating onions that were left out overnight without the stem?
Besides, the issue brought by the article is the limitations inherent in the previous studies done, not the actual results. I would like to see the actual study before I would decide to reject the previous conclusions. Small and significantly limited is still too much in the view of many, myself (and many Gedolim) included.
Once again, I don’t think that is the point.
