Verdict: Ditch it. "You want to get as many nutrients as you can with your calories," Palmer says. "You can enjoy a cup of fresh strawberries for those same 35 calories and you'll get more flavor and nutrients."
Verdict: Ditch it and make your own. Roast kale with a small amount of olive oil and seasonings to get the maximum benefit. Or if you're going to buy kale chips, look at the label and make sure kale is listed as the number one ingredient.
Verdict: Stick with it.
