When you dig into a strawberry Yoplait yogurt, take a moment to
contemplate where the beautiful pink color comes from. Strawberries?
Think again. It comes from crushed bugs. Specifically, from the
female cochineal beetles and their eggs. And it's not just yogurt.
The bugs are also used to give red coloring to Hershey Good & Plenty
candies, Tropicana grapefruit juice, and other common foods.
