Sweet but deadly:
Rhubarb may be a favorite in pies and jams, but did you know that one part of this plant is actually poisonous? While the stems are perfectly safe (and delicious), rhubarb leaves contain oxalic acid, a natural toxin that in large amounts can cause kidney failure.
Rhubarb is a delicious and versatile ingredient, but the leaves should be composted. Stick to the safe parts and enjoy this tart treat without the risk!
Deadly prayers:
Raw kidney beans contain phytohaemagglutinin, a toxin that can cause severe vomiting and stomach cramps. Eating just a handful of undercooked beans can lead to food poisoning.
Boiling kidney beans for at least 10 minutes destroys the toxin, making them safe to eat. However, cooking them at low temperatures can make them even more toxic rather than neutralizing the toxin, so be extra careful when simmering your chili.
