Why Do Blueberries Make You Poop?

Blueberries are often called a superfood due to their combination of nutrients and antioxidant compounds.One cup of blueberriescontains:

As you can see, blueberries have a good amount of fiber and they are also 84% water. (You knew they were juicy!) These things make blueberries a good food to eat when you need to poop.

The majority of the berry’s total fiber isinsoluble, a type of fiber that helps keep you regular.Insoluble fiberadds bulk to the stool, and this stimulates muscle contractions to keep things moving through the GI tract and out of the body. For this to happen,adequate hydrationis needed, and the water content in blueberries contributes to this. On top of that, the berry is packed with antioxidant compounds known as polyphenols, which include anthocyanins, quercetin and phenolic acids.Fruitswith polyphenols appear to be particularly good at preventing and alleviating constipation. Polyphenol-rich foods like blueberries may even alleviate IBS symptoms, one of which is constipation, according to a2019 study.

Do Blueberries Make Your Poop Green?

Anything we eat has the potential to change the color of our poop, but this is particularly true with some foods with vibrant color, no matter if it’s natural or added. Blueberries' deep purple-blue color comes largely from the pigments in anthocyanins, which get broken down during digestion. Any compounds that can’t be absorbed following digestion become part of your poop. According toCleveland Clinic, poop is usually a shade of brown because of bile, which is required for digestion and has a yellowish-green color. Eating pigmented foods like blueberries may make poop turn darker or turn slightly green, blue or even black if you’re eating a large amount.

Bottom Line

Blueberries are a great food to incorporate into your diet to reap the benefits of antioxidant compounds that research associates with a reduced risk for many chronic diseases, as well as insoluble fiber for gut health. While your constipation protocol shouldn’t consist of strictly eating blueberries, incorporating the fruit regularly (no pun intended) may help you poop a little easier when combined with other fiber-rich foods, adequate hydration and physical activity.
