Final answer:
Lima beans and cassava roots contain cyanide, which is a toxic chemical that inhibits cells from utilizing oxygen. It is crucial to cook these foods properly to neutralize cyanide.
Step-by-step explanation:
Lima beans and cassava roots contain a toxic chemical known as cyanide.
Cyanide is a metabolic poison that interferes with the ability of cells to use oxygen, causing harm to bodily functions.
It's important to cook these foods thoroughly before consumption to neutralize the toxin.
Lima beans, particularly when raw, contain cyanogenic glycosides which can release cyanide into the body.
Cassava also contains these compounds and must be properly prepared and cooked to prevent cyanide poisoning.
