Mskitty, there are so many things sold under the generic name "guava" it is hard to know what you're getting. Like
any tree-borne fruit, they are a good source of fiber.
Here's a photo of some unripe tropical guavas on a young tree in my yard last summer. The largest of those shown is the size and color of a small Bartlett pear. I like to pick mine in the Fall when the skin starts turning yellow but not yet brown. The center core is seedy which is easily remedied with an apple or pear fruit-corer, or just eat out-of-hand. This particular tree is a selection of "Donrom" made by Paul Fisher of the CRFG.
