1. Digestive Discomfort: The high fiber content in blueberries may cause digestive issues if consumed in excess.
2. Blood Sugar Spikes: Although blueberries have a relatively low glycemic index, consuming large amounts can still cause a rapid rise in blood sugar levels.

Moderation is key when incorporating blueberries into your diet.
