Why is it such a popular stereotype that women don’t know what they want to eat?

I always found this strange how prevalent the stereotype is. I haven’t noticed a trend of women being any more unsure of what they want to eat at any given time than men. I’ve noticed a lot of the time women do the grocery shopping for the household and usually cook. I thought this was the norm.

For context, I am a straight woman who has only ever dated men. Is this something that is actually common only during the dating phase or something?
