Whether enrobed with chocolate in a candy bar or sucked up through a straw on the beach, coconut has become shorthand for the good life: clear blue waters, white sand beaches, and an ocean breeze. But it’s not just a tropical treat. All around the world, people who live alongside the coconut palm refer to it as the “tree of life,” thanks to its ability to provide food, oil, fresh water, and the sturdy raw materials to build homes, clothes, and even musical instruments—all from one plant. But can this delicious, Swiss Army-knife of a nut (that's not technically a nut) also prevent heart disease, clean your teeth, and even stave off Alzheimer's? This episode, Gastropod cracks open what makes coconuts so great, including their role as everything from a Presidential lifesaver to the missing ingredient in nuclear fusion. We've also got the backstabbing battle that made coconut water popular, and the science on all of that Paleo coconut oil hype. Plus, we take on our toughest field assignment yet: traveling to a tropical island to taste the fruit of the tree of life ourselves—if we can just figure out how to get it open...
