According to studies, things like raw onion, scallion, or garlic are extremely beneficial for one's health (there's clear evidence of anticarcinogenic properties and inconclusive but decent evidence of cold/flu efficacy as per Cochrane).
However, despite seeing a constant example (us) of people eating it, my child refuses to even eat a little of either of those.
How can I encourage her to start eating onions and garlic and chives, even a little?
Things we tried:
Explanation of health benefits (that generally works with her, it got her to like tomatoes)
She does NOT have a major problem eating them in cooked form (e.g. fried onions or scallion in an omelet).
She'll eat pretty spicy pickles happily. We pointed out to her that those pickles contain garlic (as she saw by reading ingredients), but that didn't change her mind at all about eating garlic.
Personal example (in case of onion/chives, even her brother eats them).
We encouraged to eat just little tiny pieces in "sandwich" with meat or bread so there's no bite. She tried once and refuses since then.
