2. Aflatoxin Contamination
Peanuts can sometimes be contaminated with aflatoxins—toxic compounds produced by certain molds. Aflatoxins are carcinogenic and can cause liver damage with long-term exposure.
How to minimize risk:
Buy peanuts from reputable sources
Store peanuts in a cool, dry place
Discard any peanuts that look moldy or discolored
Roasted peanuts may have lower aflatoxin levels than raw
3. High Oxalate Content
Peanuts contain oxalates, which can contribute to calcium oxalate kidney stones in susceptible individuals. If you have a history of kidney stones, moderate your intake.
4. Calorie Density
While peanuts are healthy, they are also calorie-dense. A small handful (about 1 ounce) is a serving—not the whole jar. Mindful portion control matters.
