Can blueberries cause diarrhea?

Blueberries can, in fact, induce diarrhea.

Blueberries are a nutritious, sweet, and tart fruit that is widely used in yogurt, cereal, and other dishes. However, it’s probable that some people will have stomach problems. If you get diarrhea after eating blueberries, it could be an indication of food poisoning or an allergic reaction to the fruit.

Blueberries should be avoided if you have loose stools. They may cause your feces to take on an unusual color.

  •  You’ve been poisoned by food

Produce is a common source of food illness, according to the Centers for Disease Control and Prevention (CDC). Blueberries may become infected with infections such as Salmonella, E. coli, or Listeria while being grown and processed. According to the Centers for Disease Control and Prevention, contamination can happen even at home if the product isn’t properly cleaned or kept (CDC).

In addition to diarrhea, food poisoning can cause vomiting, stomach pains, and a low-grade fever, according to Mayo Clinic. Contact your doctor or go to an urgent care center as soon as possible if you develop a high temperature or become dehydrated or weak as a result of severe diarrhea.

To avoid food illness, wash berries well, pat them dry, and store them in the refrigerator before eating.

  • You’re allergic to blueberries.

Food allergies are caused by an overactive immune system that reacts to certain proteins, according to FARE, the Food Allergy Research & Education organization. Simply defined, it happens when your immune system incorrectly feels a portion of food is hazardous.

According to the Cleveland Clinic, a blueberry allergy can induce diarrhea, vomiting, skin rashes, swelling, shortness of breath, or anaphylaxis every time you eat them.

According to the American College of Allergy, Asthma, and Immunology, the only way to know for sure if you have a food allergy is to get a skin prick or a blood test.

If you have an allergic reaction, your doctor may provide epinephrine, steroids, or antihistamines.

Check the nutrition labels to ensure you’re not eating blueberries or anything else to which you’re allergic.

  •  An Intolerance for Fructose

Fructose intolerance is a condition in which a person is unable to consume fructose.

According to the Mayo Clinic, some people are unable to tolerate fructose, a naturally occurring sugar present in fruits, vegetables, juices, and honey. 

It’s found in both table sugar and high-fructose corn syrup. Sugar can cause unpleasant stomach symptoms such as diarrhea and gas if it is difficult to break down or digest.

In those who suspect they have fructose intolerance, hydrogen breath testing may be used to diagnose it. Although blueberries have a low sugar level, they might induce symptoms if ingested in large quantities. As a result, if you have a food intolerance, you should consume them in moderation.
