What is high fiber cereal?

Did you know that a majority of Americans consume cereal at least once a week?

This crunchy bowl full of goodness isn’t just for breakfast, either. Whether you’re enjoying a bowl at the crack of dawn, munching on it as an afternoon snack, or treating yourself to a late-night nibble, cereal can offer a significant boost to your daily nutrition if you pick the right box.

What counts as high fiber? A high fiber cereal is one that meets at least 20% of your recommended needs in a single serving.

Women need 25 grams of fiber per day, so a high fiber cereal would have 5 grams of fiber per serving.

Men need 38 grams of fiber per day, which means that they need 7.5 grams of fiber per serving for a cereal to count as “high fiber.”

While this doesn’t need to be a hard rule that you follow, it’s a good guideline to use when you’re checking out nutrition labels.

Benefits of high fiber cereal

High fiber intake plays a pivotal role in maintaining overall health and well-being. One of fiber’s most impressive benefits is that it can lower cholesterol levels.

It does this by binding with cholesterol particles in your digestive system and moving them out of the body before they’re absorbed. As a result, getting enough fiber in your diet can decrease your risk for heart disease.

Hitting your daily fiber goals also plays a crucial part in stabilizing your blood sugar levels. It slows down the absorption of sugar into your bloodstream, preventing sudden spikes in blood glucose and insulin levels, making it particularly beneficial for individuals with diabetes

But that’s not all! Eating enough fiber can improve your gut health by diversifying your microbiome — the community of friendly bacteria residing in your gut. A diverse microbiome is associated with better health outcomes, including improved immunity and digestive health.

Feeling full and satisfied for longer is another huge benefit of eating a fiber rich diet. By adding bulk to your meals and absorbing water, fiber enhances feelings of fullness, helping curb overeating and snack cravings.

This benefit of fiber is particularly beneficial for weight loss, as it can help us to feel satisfied, not restricted or hungry.

Tips for Choosing Your High-Fiber Cereal

Serving size

When selecting a high fiber cereal, the very first step is to take a peek at the nutrition facts panel and see what the suggested serving size is. All the information you see on this panel is based on this particular serving size.

So, the serving size listed on a cereal box might be more or less than what you would typically serve yourself.

For instance, if the cereal box indicates a serving size of 1/2 cup, but you tend to eat 1 cup of cereal at a time, you’ll be consuming double the calories, sugar, sodium, and of course, fiber, listed on the box.

Fiber content

Next, check the fiber content. Cereals with 5 grams or more per serving are considered high in fiber for women, and 7.5 grams per serving are high fiber for men.

Protein content

Many high fiber cereals are also higher in protein, so that may be something to look for if you’re trying to boost your daily protein intake too. I like to look for cereals that have at least 5 grams or so to help with satiety.


I also recommend taking a quick peek at the list of ingredients. The first ingredient listed should be a whole grain, as whole grains are naturally high in fiber. 

Cereals are often fortified with vitamins and minerals and can help to close nutrient gaps. Sometimes people hear the recommendations of skipping ingredients that they can’t pronounce, but that can be misleading.

The scientific names for vitamins and minerals can actually be kind of tricky to pronounce, but they’re a benefit in your cereal bowl. 


Lastly, be mindful of the sugar content. Even some high fiber cereals can be high in sugar, so take a peek so you can make a choice that’s right for you.

The American Heart Association recommends no more than 25 grams of added sugar per day for women, and no more than 36 grams for men. No foods are off limits, but you can use those numbers as a reference point when you’re making your choice.

Boosting Your Cereal Even More

While high fiber cereal is already a nutritious choice, you can enhance its nutritional profile even further. By topping your bowl with fruits, particularly berries, you add an extra layer of vitamins, antioxidants, and (ta da!) fiber.

Berries such as strawberries, blueberries, and raspberries are not only vibrant and delicious but also packed with health-boosting nutrients.

Similarly, adding nuts and seeds to your morning cereal can provide a boost of healthy fats, protein, and fiber. Almonds, walnuts, flax seeds, and chia seeds, for instance, are excellent choices that enhance your breakfast’s textural appeal while fortifying it with essential nutrients.

One of my favorite high protein, high fiber breakfasts is topping Greek yogurt with berries and my favorite high fiber cereals.

Don’t make these mistakes…

While the benefits of fiber are immense, it’s very important to make SLOW changes to your fiber intake. Suddenly adding a large amount of fiber to your diet can lead to constipation (or diarrhea!), bloating, and significant discomfort. 

The best approach is to add it slowly, giving your digestive system time to adjust. 

Just as important is staying well-hydrated, especially as you up your fiber intake. If you dial up your fiber intake without enough water, you’re at risk of major risk of constipation. Slow and steady, with plenty of fluids, is best. 

What if I don’t like high-fiber cereal?

If the recommended cereal isn’t cutting it for you and your taste buds, don’t eat it! I would never recommend that you force yourself to eat something that you don’t like. 

You also have the option to mix a high-fiber cereal with your current favorite cereal so you get a winning combo of taste AND fiber. 

You can also pack a lot of fiber into smoothies if you know what ingredients to pick. Here’s my favorite High-Fiber Smoothie Recipe. (P.S. It is also delicious as a popsicle if you pour the mixture into popsicle molds.)

Lastly, if you choose high fiber bread, your lunch can easily be a high-fiber meal, without taking a lot of time. I have a whole article on my favorite high fiber breads, too!
