Ever since its hippie heyday, when granola was at the top of the earth child food pyramid (right above sprouts and tofu), the rolled oat cereal has been virtually synonymous with healthy eating. It’s the reason you still occasionally hear such diets referred to as “crunchy.”

And it can be a great source of whole grains, fiber, and even protein. Or, depending on the brand, fat, sugar, and calories. “One of the biggest issues with granola is portion size, because it’s incredibly dense,” says Karen Ansel, R.D., author of Healing Superfoods for Anti-Aging: Stay Younger, Live Longer. You’ve got to read labels carefully because the serving sizes vary a lot from brand to brand, from as little as a quarter cup to double that. Luckily, a little does go a long way as a yogurt or salad topper, or for snacking straight from the bag.

Ansel recommends scanning the ingredients list for whole foods such as nuts, seeds and whole grains, and minimal added sweeteners. We put our spoons to the test and declared these granolas best in bowl.

All-Around Healthiest: Nature’s Path Hemp Hearts Granola

Best for Your Gut: Purely Elizabeth Maple Walnut Probiotic Granola

Literally and figuratively, this cereal’s as crunchy as they come.

Best Classic (Or Old-Fashioned): Bob’s Red Mill Cinnamon Raisin
