Black Stool Blueberries How Longの主要なニュースを専門的かつ分かりやすくまとめました。最新トレンドを一目で把握できます。

Here’s the science, but the fun kind. Blueberries are packed with a pigment called anthocyanin. It’s the same stuff that makes red cabbage red and eggplants purple. It’s a powerful antioxidant—basically a tiny superhero living in your fruit.

But here’s the kicker: your body doesn’t digest all of it. When you eat a ton of blueberries (like a whole pint, or that “healthy” smoothie you chugged), some of that pigment passes right through you. It’s like a stubborn stain that refuses to leave your Tupperware, except the Tupperware is your large intestine.

The anthocyanin mixes with your digestive juices and turns from purple to a deep, inky black. It’s not blood. It’s not a sign of a curse. It’s just fruit graffiti on the inside of your colon. Fun, right?
