Spinach is one of the most consumed veggies globally (#8 or #9) and has no emoji. And WhatsApp at least has no emoji results for "chili"/"chilli" - you have to search for "pepper". But there's no emoji for ground pepper!
I noticed proposals use google/bing search results (in english) to show support for an emoji. If they used multiple languages to show popularity (at least english, spanish, french, and mandarin) it would look different.
In general emoji are very us-centric, for example the police car emoji doesn't look like a police car to many cultures.
