A card that indicates categories or types of food in general, and quickly identifiable allergens.
Creating one standard is important. And for everyone. I keep seeing using colors for indicators, but that doesn't help for colorblind people, so should cover everyone. And also text printed in dyslexic readable fonts.
I would like to see ingredients detailed out in a standard organized fashion so that I can quickly check and see if it contains ingredients what I like or dislike.
I've only seen some cards placed to indicate what is gluten free. But not much else.
Hopefully this will make things easier for people with allergies, and people like me who hate a particular ingredient that some people are allergic to.
And I can be pickier when eating at a pot luck. And stop rejecting things cause I'm not sure.
