So, here's an odd question.

A few years ago, my home ed. teacher told us that she would not eat anything that is colored blue. it's unnatural.

Thinking on this, I confronted her about blueberries. She argued that blueberries are purple. Okay.

What vegetables, fruits, meats, or spices are naturally blue (either before or after preparation)?

^{(For all intents and purposes, yes, blueberries are blue)}
