Bitter almonds
Janthiwa Sutthiboriban/Shutterstock The almonds that we know and love are also called "sweet almonds," and there are some excellent health reasons to eat them. Bitter almonds are kind of like their evil cousin. They're a variety of sweet almonds, but they contain hydrocyanic acid, which is a dangerous combo of hydrogen cyanide and water. According to The Spruce, it would only take about 70 raw bitter almonds to kill a fully grown adult. Yikes! Thankfully, they're safe to eat if they've been cooked, and most U.S. grocery stores don't sell them. The likeliest places you'll encounter them are in almond extract and almond-flavored liqueurs. Can you guess the five healthiest nuts you can eat?
