Bit Idea: Come up with some fake ingredients

I have a tub of ranch dip and right on the top of it in big bold letters it says "Only Real Ingredients!!" I don't know what this means. I assume that means there are fake ingredients out there somewhere, imaginary ingredients, and that other brands are using those fake ingredients rather than the real ones this brand uses.

Anyway come up with some fake ingredients and then tell me what purpose they serve in those other brand's ranch dip. Also yes I'm eating ranch dip so you can also make fun of me for being a but do the bit too.
