Have you ever thought about red foods? Do you know what makes them red?
Well I know that iron oxide gives mars a red tint so maybe something to do with that.
It's much worse than that actually. The dye Red 40 is actually made from crushed red beetles. My daughter, who is vegetarian, found that out.
I did not know that, is that when you don't eat any meat like chicken or steak?
Yes, but as she has learned more, I have also. Gelatin in foods (Jello) is made from boiled animal bones. I'm not vegetarian, but even I limit red foods and gelatin now.
I understand. I like red sky at sunset. It comes from rayleigh scattering.
