36. Rhubarb

Don’t panic, rhubarb fans! This tasty vegetable is still a-okay to tuck into at home. Its leaves are a different story, however. Taste of Home magazine’s website reported that those bits of greenery house oxalic acid. To put it simply, if you eat lots of rhubarb leaves, you’ll be badly poisoned. We’d keep our hands away from that area going forward.
