Why Do Berries Give Me Diarrhea?

Blueberries can cause diarrhea for a plethora of reasons. One of the most common reasons for diarrhea after eating a ton of blueberries is fructose.

Fructose is found in many fruits and is known to cause loose and watery stools when consumed in excess. Because of this, you may expect to have diarrhea when you eat too many blueberries, although this is not the case for everybody.

If you have frequent loose stools after consuming blueberries, or any other fruit for that matter, consider speaking with your doctor about the possibility of fructose malabsorption as an issue.

Can Too Many Blueberries Cause Diarrhea?

We’ve already discussed the role that fructose plays in why blueberries can sometimes cause diarrhea. But it is also important to note that the fiber content of blueberries may also be to blame when it comes to excessively loose stools.

For those who are not used to eating a lot of fiber, or for those who simply ate too much, the excessive fiber intake can cause bloating, abdominal pain, gas and you guessed it…diarrhea!

Do Blueberries Cause Diarrhea in Babies

Yes, blueberries can cause diarrhea in babies.

Blueberries can cause diarrhea in babies the same way they can for adults, and sometimes, maybe even more so. This is because a baby’s digestive system is more sensitive. Thus, they may not be able to handle it if your baby consumes an excessive amount of blueberries.

Note also that your baby may excrete dark blue or black stools after consuming blueberries. This, however, is normal and not a cause for alarm.

Why Do Fresh Blueberries Cause Diarrhea

Fresh blueberries cause diarrhea because they are rich in both fiber and fructose. Both fructose and fiber have been known to cause diarrhea or loose and watery bowels when consumed in large amounts.

Yet another common reason that blueberries can cause bowel movements and diarrhea is that they can sometimes contain bacteria. These bacteria weren’t washed off prior to eating.

Interestingly, according to the CDC, most cases of food poisoning often come from the consumption of unwashed produce. As a result, you must learn how to wash blueberries to remove any harmful bacteria that may be present before eating.

Do Blueberries Cause Bowel Movements?

Blueberries cause bowel movements and can be particularly helpful if you are constipated.

Because of their high fiber and fructose content, blueberries tend to move the bowels rather easily. Combining your blueberries with a little yogurt, some dairy or non-dairy milk, and a banana will likely get your constipation issues under control in as little as a few hours. You may also consider throwing in a few chia seeds for even more fiber to help your bowels move.

Aside from normal bowel movements, it should be noted that blueberries can, at times, cause diarrhea as previously mentioned in this article. As such, it is important that if you notice your bowels begin to change after consuming many blueberries, you stop eating them.

See a healthcare professional if your diarrhea is severe or doesn’t clear up within a couple of days.

Are Blueberries Bad For Your Stomach?

They can be.

Depending on how sensitive you are to fiber and fructose, blueberries have the propensity to cause your bowels to move, or worse, become diarrhea if consumed in excess.

To prevent this from happening, consider limiting the number of blueberries you eat per day. Mix up your intake of blueberries with veggies and protein to strike a better balance within your diet.

Still, consuming only a handful of blueberries at a time is unlikely to cause most people issues.

Blueberries Upset Stomach

Have blueberries caused you some tummy troubles? Blueberries may cause an upset stomach in certain individuals who have sensitives. But they can also cause problems for those who consume raw blueberries that contain bacteria.

Remember that blueberries and other products are often contaminated with germs as they are processed and sold in markets. As a result, you must wash blueberries before consuming them.

Consider making your own fruit and vegetable cleaning solution. Combine two parts of water to one part white vinegar before enjoying your fruits and veggies from the market.
