(It contains a lot of information about our most common nuts.) This food safety article describes aflatoxins, forms that develop on certain raw foods while certain nuts are ingested.
Amygdalin and bitter almond cyanide can provide 4 to 9 mg of hydrogen cyanide per almond and contain 42 times more cyanide than the traces found in sweet almonds. The cyanide content of bitter almonds comes from the enzymatic hydrolysis of amygdalin.
It’s actually the good monounsaturated fat (MUFA) content in cashews that helps. Our diet has traditionally been deficient in MUFAs, which can be harmful to heart health, and cashews help fill that void. Additionally, cashews actually have a lower amount of fat (13 grams per ounce) than most other nuts.
