  Acai berry is a fruit that is commonly found in antioxidant boosters or weight loss products. Acai berry, or the products it is contained in, are not controlled by the Federal Drug Administration (FDA) so the full benefits and side effects do not have to be thoroughly researched and may not be known. While acai berries are natural and when eaten in moderation should not pose a health risk to a healthy individual, there are some side effects people should be aware of.
  
  

Allergies

• According to Web MD, individuals with pollen allergies or hypersensitivity to acai, or similar berries, such as blueberries, should avoid this fruit for risk of allergy symptoms. Food allergy symptoms may include any combination of swelling of the throat, swelling of the face, rash or hives, itchy or watery eyes, congestion or trouble breathing.
  
  

Diarrhea and Stomach Cramps

• Dr. Paul Gross reported that in 2007 two studies conducted on the acai berry concluded that the acai berry has a high fiber content: 35 percent. Because of this high fiber content, acai acts as a natural laxative. The laxative can cause you to have stomach cramps as it moves the waste along. Additionally, it helps soften hard stools sitting in the colon, which can lead to diarrhea.
  
  

Interference with Chemotherapy Drugs

• Acai berry should not be taken by individuals receiving chemotherapy. The Memorial Sloan-Kettering Cancer Center reports that due to the antioxident effect that the acai berry has, it may interfere with certain chemotherapy drugs and the actions the drugs are supposed to perform. The full effects are not known and further testing is being conducted.
