can you eat too many blueberries

Yes, it is possible to eat too many blueberries. Consuming a large amount of blueberries can cause digestive side effects such as bloating, gas, stomach pain, cramping, and diarrhea, primarily due to their high fiber content. For people not used to high fiber diets, increasing blueberry intake too quickly can worsen digestive discomfort. Additionally, blueberries contain vitamin K, which can interfere with blood-thinning medications if consumed excessively. They also have natural sugars that might impact blood sugar levels, particularly in individuals with diabetes or those on blood sugar medications. Some people may also be sensitive to the salicylates in blueberries, leading to allergic reactions or headaches. The recommended serving size is about 1 cup of blueberries per day, which is generally safe unless causing adverse symptoms or interacting with medications.
