Some foods can totally transform you from a cold-addled snot monster to the picture of health. But there's a surprising number of everyday foods that, if you're not careful, could straight-up wreck your day. Or slightly worse, end your life! Don't worry, getting poisoned by them is gonna take some effort. And most of them are veggies anyway, and we all know you don't eat those.
Cherries That cherry orchard your family used to go to during cherry season? Death trap! Well, not really, unless somebody manages to chew through a bunch of cherry pits and swallow them. And if anyone could do it, it's your idiot cousin Stu. Like the worst cherry cordial ever, those pits are loaded with hydrogen cyanide. Yep, that cyanide. Luckily, the pits are so thick and hard you can swallow one and it'll come out intact, which is its own punishment.
Wild Almonds Scientists recently discovered that people who snack on almonds throughout the day eat less at mealtime. Probably because THEY'RE DEAD. Not really. We eat sweet almonds, not wild almonds, which are bitter. They're also loaded with cyanide and could totally drop you. Luckily, you're not gonna see them around. But if you find yourself in the wild and see some green almonds, maybe don't eat them.
Castor Beans
That castor oil crap Granny gave you to make you puke back in the day is derived from the castor bean. Which, it turns out, is also an excellent source of ricin when it's raw. Your Grandma is also a psychopath and, quite possibly, the mastermind behind an international meth operation.
Apples
It's unlikely that you're gonna do much damage to yourself if you eat the seeds out of an apple or two, but keep it up and you're in trouble. Your body's enzymes tend to morph compounds in the seeds into -- yup -- cyanide. That could explain why the old Johnny Appleseed story just kind of trails off. Kids would probably freak if they knew he was dead somewhere with a tree growing out of his greedy stomach.
Tomatoes
Until the 1800s, most people in the U.S. thought tomatoes were outright poisonous. They also thought powdered wigs looked good, but they were kind of right about the 'maters. Tomatoes are part of the nightshade family, and that whole "poisoning people" thing apparently runs in the family, since their leaves are laced with toxic tomatine.
