If your potatoes have a greenish tint, beware! This color indicates the presence of solanine, a toxic substance that can cause nausea, vomiting, and even confusion. A good peeling, and presto, the danger is averted.
Raw cashews: falsely harmless
In stores, they’re always roasted, and that’s no coincidence. Raw cashews contain urushiol, an irritant also found in some poisonous plants. Consuming them this way can cause redness, itching… and much worse.
Nutmeg: a spice with unexpected effects
Used sparingly, nutmeg enhances dishes. But in large doses, it becomes hallucinogenic! Two teaspoons are enough to cause serious problems: delirium, nausea, disorientation lasting several days. Handle with care…
Wild mushrooms: a dangerous game
Every fall, mushroom enthusiasts end up in the hospital for picking the wrong mushroom. Some are deadly, like the death cap, which is almost identical to other edible species. Unless you’re a seasoned mycologist, it’s best to stick to market mushrooms.
Rhubarb: watch out for the leaves!
While its stems are delicious in pies, its leaves are a no-no. Filled with oxalic acid, they can cause severe kidney problems. There’s only one rule: stems yes, leaves no!
Red beans: cook thoroughly, or nothing
Just a few raw or undercooked kidney beans can cause food poisoning. Phytohaemagglutinin, a natural toxin, is responsible. It’s therefore essential to boil them for at least 10 minutes before cooking.
