When Europeans very first encountered the tomato on their earliest access time to the new World, it to be feared. A glowing red—suspiciously shining red—fruit in the same household as the deadly Nightshade, a legendary poisonous plant? No, say thanks to you!

The tomato, the course, is not poisonous, however the europeans were appropriate to it is in wary the it. There space plenty of fruits, vegetables, tubers, and also other plants that us heartily consume that are, secretly, dangerous come our health if prepared or eaten improperly. Here are part you may not have known about.

You are watching: Is rhubarb in the celery family

1. Tomato

I know, I simply said the tomato isn’t poisonous. The fruit isn’t, yet the leaves, roots, and stem (and, in restricted doses, even some unripe fruit) room rich in tomatine, one alkaloid that’s mildly toxic to humans. It won’t death you, unless you chow down pounds and pounds that it, however it is most likely to reason you part gastrointestinal distress.

2. Apples, Cherries, and Apricots

The seed of all of these fruits room not considered edible; they’re hard, bitter, and also unpleasant. The bitter smell is a safety element: The tree puts it over there to discourage pets like us from damaging them. And it comes from a substance called amygdalin, i m sorry turns right into cyanide once it come into call with acids in the human digestive system. Cherries, apricots, peaches, and also nectarines have the substance in much greater concentrations than apples, but every one of the seeds and pits in these fruits are fantastically tough. Even if friend swallowed some? No big deal. Her body will just pass them out. That said, please execute not pulverize and also then consume cherry pits.

3. Kidney Beans

Many legumes can reason mild gastrointestinal distress once undercooked, yet red kidney bean (the kind practically always provided in chili) room special. Kidney bean contain phytohaemagglutinin, a chemical compound that i will constantly have to copy and also paste because, space you kidding me through that word? ingestion of also just a couple of undercooked kidney bean can cause serious diarrhea and vomiting. Follow to the FDA, it’s not fatal and also rarely outcomes in hospitalization, but it’s reasonably common for civilization to end up sick after chomping down on some simply soaked beans.

4. Rhubarb

Rhubarb, a springtime stalk most commonly used in the production of America’s ideal pie, the strawberry-rhubarb, is a very strange plant indeed. Most frequently used in sweet applications, it’s a sour vegetable the looks prefer crimson celery. And also its leaves room spectacularly poisonous. Rhubarb pipeline are really high in oxalic acid, i m sorry quickly reasons kidney fail in humans. About 25 grams the pure oxalic acid is the average amount needed to kill a human. That said, rhubarb pipeline aren’t pure oxalic acid, and it would certainly take roughly 11 pounds that the pipeline to secure the much. However still! I’d stay away.

5. Asparagus

Like the rhubarb, the part of the asparagus plant that we love – the young trunk – room perfectly safe to eat. However the asparagus hides a deceptive, nasty secret: that fruit, which room bright red berries, room toxic come humans. Simply a handful can cause vomiting and diarrhea, though a little bit of charcoal will certainly clear that appropriate up, according to the excellently named Asparagus girlfriend site.

6. Cashews

Cashews are another delicious product that should never, ever be consumed raw. (When friend buy them, they’ve usually been roasted.) native to the Amazon, the cashew is no really a nut, however rather a seed that protrudes oddly native the bottom of a fruit (also edible, though seldom seen external the tropics) dubbed the cashew fruit. You may have actually noticed that cashews are never discovered in their covering as almonds or peanuts are, and that’s because when raw, they’re covered with anacardic acid, closely related to the mountain that makes poison ivy for this reason irritating. It’s lot worse once you eat it.
