Cereal is one of the most common breakfast choices in America, and for all ages. With so many cereal brands and varieties on the market shelves, it can be difficult to know which cereals make for wholesome options.


Most cereals are made up of primarily carbohydrates. Carbs are an essential macronutrient that is your body and brain's main energy source. When carbs are digested, they are broken down into glucose, which is used for brain functions like memory, thinking and learning, according to Harvard Medical School.

But too many carbs coming from added sugars can lead to health issues like weight gain, type 2 diabetes and heart disease, according to a November 2016 article in Nutrients.

"Keeping your carb intake low at breakfast can help set you up for more stable blood sugar throughout the day and prevent that mid-morning crash that has you reaching for high-carb snacks and another coffee refill," says Heather Ayala, RD, CKNS.

It is also extremely low in sugar and contains no artificial sweeteners, colors or flavors.

The first ingredient in Cheerios is gluten-free whole-grain oats, followed by just a few other simple ingredients. This popular cereal is fortified with a variety of vitamins and minerals to help meet daily nutrient needs.

"This cereal also doesn't contain sugar alcohols, as many low-carb cereals do, which can cause discomfort in the digestive tract for some sensitive people. As a bonus, it doesn't contain any of the top eight allergens, so it can work well in families that need to be allergy-conscious," Burkholder says.

"Slightly higher on the carb count at 11 net grams per 1/2-cup serving, you get the benefits of a crunchy, sweet bowl of cereal. The Blueberry version is full of dried coconut, a variety of nuts and seeds and beneficial spices like nutmeg and cinnamon." Ayala says.

How to Choose a Healthy Low-Carb Cereal

When choosing a low-carb cereal, there are a few things you should keep in mind to make sure you select a nutritious option:


1. Low in Sugar

If you're looking for a low-carb cereal, you'll definitely want to also make sure it is low in sugar. Eating too much sugar has all sorts of negative health effects including weight gain, diabetes, inflammation, high blood pressure and more, according to Harvard Health Publishing.

It is best to stick to cereals with 10 grams or less of added sugar per serving. This will help you stay within the added sugar limits recommended by the American Heart Association.

2. High in Fiber

Fiber is a type of carbohydrate. However, it's not digested, so it doesn't raise blood sugar or provide any calories. There are so many health benefits to eating more fiber, including better gut health, better blood sugar control and a healthy weight.

It's best to choose low-carb cereals with ideally 3 or more grams of fiber per serving. If you want to add even more fiber to your bowl, try sprinkling some nuts or seeds on top.

3. Good Source of Protein

A combination of fiber and protein will help keep you full for hours by keeping your blood sugar stable, rather than causing a blood sugar spike followed by a crash. This combination is also best for weight management.

"If you can find a cereal with 3 or more grams of fiber and 10 or more grams of protein, you'll find the cereal is much more satisfying and will keep you full longer," Burkholder says.

4. Simple Ingredients List

Typically, the shorter the ingredients list, the better. This makes it less likely to contain things like preservatives and artificial ingredients.

"Ingredients are listed by weight, so if the first ingredient is a whole grain, for example, you'll know that most of the cereal is derived from whole-grain ingredients, which are high in fiber, vitamins and minerals," Burkholder says.

As another rule of thumb, look for mostly whole-food ingredients you can recognize.
