Breakfast cereal has a bad rap thanks to its history as a sugary treat for kids. It went from being one of the best ways to start the day to becoming one of the unhealthiest. As nutrition has evolved, so have cereals choices. Beyond sugar-laden options, we now have cereals to suit every diet including low carb, high fiber, keto, diabetic friendly, with low-sugar to unsweetened options.

But just because a cereal is low in sugar or free of sugar doesn’t mean it’s a healthy choice or automatically low in carbohydrates. What's more, sticking to portion sizes is important to prevent you from turning a low-sugar option into a high-sugar one. When looking for healthy cereal options, our nutrition experts say to search for 100% whole grain or whole food as the first ingredient. Think ingredients like whole grain oats, legumes, nuts, corn and buckwheat. You'll also want to choose an option with a combination of protein and fiber (3 grams of each per serving is ideal). If you’re pairing cereal with yogurt, milk or alternative milks, make sure to take into account added sugars that might be lurking in those products that could turn your meal into a sugar bomb.

Registered Dietitians in the Good Housekeeping Institute Nutrition Lab tested a variety of cereals to find the best low-sugar options out there. We looked at brands that contain 4 grams or less of total sugar per serving, since one teaspoon of table sugar equals four grams of sugar.

Here are the best low sugar cereals of 2022:
