The scientific reality is quite the opposite:
What science actually says
Extensive medical studies show that regularly eating nuts can reduce the risk of various cancers and cardiovascular diseases, rather than increasing it.
Rich in antioxidants: Nuts contain vitamin E, polyphenols, and other phytochemicals that reduce oxidative stress and protect cells from damage.
Anti-inflammatory: The healthy fatty acids they contain (such as omega-3) help reduce chronic inflammation in the body, which is a known risk factor for cancer.
Fiber: The risk of colon cancer, in particular, can be reduced by a high-fiber diet, to which nuts also contribute.
Where does the myth come from? (The Spark of Truth)
There is only one specific scenario in which nuts can be a health hazard: mold infestation.
Aflatoxins: If nuts (especially frequently imported peanuts or pistachios) are stored improperly, i.e., in excessively humid and warm conditions, the mold Aspergillus flavus can develop.
