This 'healthy choice' actually delivers as much sugar as a candy bar," says nutritionist Monica Reinagel, LN, CNS. "Yogurt is a good source of calcium, protein, and beneficial probiotics. And fruit is a good source of fiber and antioxidants. But 'fruited yogurt' cancels out the benefits by containing up to six teaspoons of added sugar per serving." Many yogurts (especially low-fat ones that look extra healthy) pack artificial sweeteners that can kick your taste buds into overdrive and actually raise your tolerance to any and all things sweet, adds Glassman.
Shop smart: If you need some fruity flavor in your yogurt, buy the fruit fresh and mix it into plain yogurt, she says.
