Clementines are one of my favorite citrus fruits because they're easy to peel, and they're sweet like tangerines but don't contain any seeds. Also, one clementine is only 35 calories and contains almost 1.5 grams of fiber. I love that you can buy them in cases, but one thing you need to remember is to wash them before you peel them. Even though you don't eat the peel, when you peel your clementine, germs and pesticides can transfer onto your hands. So when you eat fruit inside, you can end up ingesting bacteria and chemicals. So wash this orange fruit before enjoying it. Actually, this is a great tip for all fruit you're going to peel, including bananas, mangoes, and kiwi.
