Guava is another one of those power-of-suggestion snacks and while it, naturally, can't take you physically to a tropic location; it'll make you think of a warmer locale. The taste has been described as a mix of strawberry and pear. You don't have to peal guava or spit out the seed -- the rind and seed are both made to be eaten [source: The Fruit Pages].
Lots of health benefits can be derived from guava. It's filled with antioxidants, iron and vitamin C [sources: Men's Health; The Fruit Pages]. If you find yourself thirsty after a jaunt in the cold, they're also a great source of sweet hydration.
