Bacon

If you love bacon, this will make you jump for joy: Rachel Begun, RD, a food and nutrition consultant in Boulder, Colo. eats bacon. "It's got such a salty, smoky flavor that you can use small amounts to jazz up veggies—in fact, a little bacon can make you love veggies more," she says.

The key here? Small amounts. Bacon can be loaded with salt and saturated fat, which is why you want to use it more like a garnish than a main event. Sprinkle crumbled bacon atop a side dish of Brussels sprouts or a veggie-filled salad.
