1. Granola
Granola has a wholesome reputation, but most commercial varieties are far from guilt-free. Many are loaded with added sugars and oils to create those crunchy clusters we crave. Just a small serving can pack as many calories—and as much sugar—as a dessert. If you’re not reading the label carefully, your “healthy” breakfast could be spiking your blood sugar and adding unnecessary calories. Learn more from Harvard T.H. Chan School of Public Health.
