Is Antimatter Really Dangerous?

There are so many basic questions about the universe that we do not have answers to. Antimatter when it hits real matter will annihilate into photons, but bananas contain potassium, which is unstable. It undergoes radioactive decay emitting positrons, which are anti electrons. When those do hit your body, they will annihilate and create a tiny little flash of light. But it's such a tiny amount of antimatter that it doesn't really matter.
