Potential Downsides of Peanut Butter
While peanut butter shines as a nutrient-dense food, there are some risks and disadvantages to consider, especially from excessive or daily consumption.

Food Allergies and Safety Concerns
- Peanut allergies can be severe and are among the most common food allergies in both children and adults.
- Peanuts may be contaminated by aflatoxins, naturally occurring toxins produced by molds. Most reputable companies test for these, but concern remains.
