Criteria Used for Evaluation
To understand the nutritional value of fiber cereal, it is important to first understand the function and benefit of the fiber itself, and how it will affect your body and your lifestyle. The main function of fiber in the diet is to move food and bulk through the intestines more efficiently. It also helps control the pH balance and acidity in the intestines, which serves a key function in helping fight against colon cancer. Fiber is also helpful in prolonging stomach emptying time, which helps your body better absorb key vitamins and nutrients.
Ultimately, fiber aids your digestives system in helping the rest of your body (and your day) run smoother. The benefits of fiber are far and wide – it helps maintain regularity and prevent constipation, as well as help bulk up stool if you tend to suffer from chronic diarrhea. Fiber also helps move bulk and waste through the colon more efficiently, so that it does not stick around for too long which can literally poison the colon and lead to an increased risk of cancer.
The obvious first thing we considered when ranking the cereals in our list is fiber content. A good fiber-rich cereal should have adequate amounts per serving. Although there is no dietary reference intake for fiber (meaning, the FDA does not have an amount of fiber intake that it says should absolutely be apart of your diet), experts recommend 25 to 30 grams of fiber per day as part of a holistically healthy and well-rounded diet. Furthermore, six to eight grams of fiber should be coming from the soluble fiber in order to get the most benefit. A decent fiber cereal will have a substantial percentage of your recommended daily intake of fiber. Our list aims to get in anywhere from 5 grams of fiber to almost 40 (which will make it super easy to get in your daily fiber!). By and large, cereals are typically talked about as great foods for children because they are often largely fortified with essential vitamins and minerals.
It just takes a quick glance at most cereal labels on the supermarket shelves to see that they come fortified with high amounts of vitamins and minerals that are essential to growth and overall health – specifically, Vitamins C, E, D, and decent amounts (as in, around 10 to 20 percent of your daily value) of iron, calcium, omega 3 fatty acids, etc. A nutritious cereal as part of a healthy breakfast is not only about what it has but about what it is FREE of. In our case, we looked to find cereals that were lower in or completely free of cholesterol and added sugars.
Sugar can be trickier. Many kinds of cereal have a high sugar content, especially fiber-rich or health-conscious cereals that use large amounts of sugar to make the taste more bearable. Even cereals that don’t taste sweet can have surprisingly high amounts of sugar. Not only do you want to avoid added sugars, but a good fiber cereal won’t have a ton of sugar substitutes (like Splenda or other sucrose and aspartame products) either. We made sure to prioritize cereals that had less sugar for our list.
Finally, when it comes to choosing cereals based on nutritional content, we considered the overall calories per serving, as well as the amounts of fat, carbohydrates, and protein per serving. The cereals on our list range from just 60 to 80 calories per 3/4 cup serving to upwards of 250 calories per serving. Both ends of the calorie spectrum have their benefits and pitfalls. However, with fewer calories often comes less taste as well, so be mindful of this when considering which option is best for you. Plus, these higher calorie options will also have higher macros – higher protein, higher carbohydrates, and higher fats.
Just because the cereals on our list are packed with nutrients and loaded with fiber does not mean you should have to sacrifice taste! Traditionally, healthier cereals get a bad rap for taste for typically one of two reasons: they either taste like the cardboard box that its sold in or it is overly sweet in an attempt to make it more palatable. Then, not only does it end up tasting more like an ice cream sundae bar topping, but the sugar just adds to an already high amount of carbohydrates that cereals typically have because they are made from grains and wheat. The cereals listed here run the range of taste according to consumers.
Some reviewers do claim that the “stripped down” and basic fiber cereals like All Bran Buds and General Mills’ Fiber One Cereal taste a bit bland and need to be served up somewhat creatively to improve the taste. If you are in search of fiber cereals that have been reviewed as the yummiest, you are safe to go with the cereals that contain a variety of ingredients. Those on our list that have other bits of chocolate, granola clusters, and dried fruit like Post’s Grape Nuts and Kashi‘s Go Lean Crunch also have the highest ranking taste. If you have little ones who tend to be pickier eaters, but you need to get some fiber into their diet early on in the day, these options are some to keep in mind. There are a few “classics” on our list too, that get rave reviews from adults and kids alike. Kellogg’s Mini Wheats might be slightly lower in fiber than other options on the list, but they taste great and are favored by a wide variety of people.
One more thing we considered when looking at each cereal’s taste was texture. Texture can really make or break a taste experience. Dry cereals, like the bulk of our list, are not hot cereals; they should have an appropriate crunch. Even when served mixed in milk, most of the fiber cereals on our list maintain their crunchy texture (notably, General Mills’ Fiber One cereal and Post’s Grape Nuts)
Cereals can, surprisingly enough, get pretty expensive especially if they have a “natural” or “organic” label tied to them. Some cereals that emphasize in certain special dietary needs, like fiber, can only be found in specialty stores. This can mean higher prices for these health-conscious foods, but luckily plenty of generic and household brands have caught onto the fiber craze. A large number of the cereals on our list can be found in just about any grocery store and are fairly inexpensive while still offering the dietary fiber you need.
Another way to keep costs down, and one which we considered when making our list, is whether or not the cereal can be bought in bulk. Not only did we think about those cereals that are sold in bulk at bulk warehouses, but many specialty and health food stores these days have “bulk bin” sections that sell various cereals and types of granola. Cereals are also more likely to last a long time, so you don’t have to worry about them going bad when you buy them in bulk.
We also considered how convenient and versatile each cereal is because that can definitely add to the value of what you’re getting. The more ways a cereal can be eaten or prepared, the better. So, many of the fiber cereals on our list can be eaten as a snack, a great addition to homemade trail mix, a smoothie ingredient, or something to bulk up your yogurt, ice cream, and oatmeal! Getting even more creative, you could use a lot of the cereals on our list as a healthier alternative to pastry dough in a pie crust.
If you aren’t already paying close attention to the nutrition and ingredients in your food, we advise you start – especially if you want to start adding in fiber to your diet. The reason being is that you might already have an adequate amount of fiber in your diet, and adding too much fiber can actually end up backfiring. Too much of a good thing, in this case, can be a bad (er, uncomfortable) thing, especially for your tummy and digestive system.
If you track your intake and find out that you do, in fact, need to add some more fiber into your daily intake then we suggest you do so very slowly because the bacteria that line your stomach and small intestines need time to get used to a fiber increase. If you add fiber too quickly, you will likely experience lots of gas, bloating, cramps, and diarrhea. Need some suggestions on where to start? Try adding in just five grams of fiber into your diet every day for two-week intervals. You might still experience some minor gastro issues but it will be limited compared to what it would be if you added too much fiber in too quickly.
Expert Interviews & Opinions
Fiber is really important, even if you are regular. It keeps your colon, heart, and bodily organs running and up to par so you can get to running and exercising. Make sure to get the right amount and you will notice an improvement in your everyday life.
Adults should consume between 25-30 grams of fiber, but most Americans only consume 15 grams. While the cereals on our lists are excellent sources, adding a fiber supplement to your diet may be a great idea!
Other Factors to Consider
Bottom line, fiber is important and is necessary that you get the right amount. Make sure you have other fiber-rich foods, not just cereal--although you will find that the choices on our list are all excellent picks. If you are gluten-free you will find that those have less fiber compared to those that have gluten. So, if you don't have to have a gluten-free option then you may want to go with something else just because it has more fiber.
Make sure you like the way your cereal tastes and ensure that you are getting a cereal you know you will eat. If it doesn't make your taste buds happy then you probably won't eat it--and while healthy choices are important, it's also important we actually enjoy our food.
You will find that some cereals on our list have more fiber than others. If the cereal is going to be one of your main sources of fiber then you will definitely have a higher potency of fiber. However, if you are using it in conjunction with other fiber-rich foods than you can go with whatever you like best, even if it is a little lower in fiber count.
After looking through our list you also probably noticed that the gluten-free cereals have a lot less fiber--so if you are gluten-free you will definitely have to supplement with other fiber-rich foods. It is important that adults will need 25+30 grams of fiber a day so make sure to plan your meals accordingly.
Frequently Asked Questions
Fiber is a type of carbohydrate, found in plant cells, that the human body cannot digest or break down. There are two main kinds of fiber: water soluble and water insoluble fiber.
Soluble fiber is a type of fiber that absorbs water during digestion. They add bulk to stool, which helps fight diarrhea and similar symptoms. Soluble fiber is the fiber found in some fruits and veggies, legumes, and oats. Insoluble fiber does not absorb water and therefore remains unchanged during digestion.
This is the fiber that helps with constipation because it pushes material through the intestines without first being broken down. Insoluble fiber is also found in fruits and vegetables (particularly with edible peels and seeds), cereals, whole grain products, oats, and brown rice. Although there is no dietary reference intake for either type of fiber, it has been recommended that adults aim to get at least one-fourth of all dietary fiber from soluble fiber.
A high fiber diet has been proven to help reduce a variety of health risks and conditions, including heart disease, diabetes, diverticular disease, constipation, and colon cancer. Like we’ve already mentioned, fiber is important for maintaining and improving the digestive system. Soluble fiber, in particular, is important because it has been shown to reduce cholesterol levels of bad cholesterol (LDL).
Aim for 25 to 30 grams per day of total dietary fiber, with 6 to 8 grams coming from soluble fiber. But don’t worry too much about the numbers – simply trying to get at least one serving of whole grains, cereals, or legumes into each meal with typically get you to that 25 to 30-gram sweet spot range.
Grains, whole grains, legumes and beans (kidney beans, black beans, white beans, etc), whole fruits and veggies (NOT fruit juices) are all great sources of fiber.
Raspberries take the cake, with one cup packing 8 grams of fiber. Apples, oranges, tangerines, pears, a cup of blueberries and a cup of strawberries all have around 3-4 grams of fiber per serving. A medium sweet potato, 1 cup of carrots, or half a cup servings of peas, cauliflower, and squash have 3 to 4 grams of fiber.
Unlike other supplements, most fiber supplements don’t actually have as much fiber as fiber amounts found in foods. In fact, for the majority of fiber supplements found on the market today, most average only about 0.5 grams of fiber per tablet. Furthermore, there is not a ton of scientific evidence that show and prove the effectiveness of fiber supplements. If you really want to increase dietary fiber intake, read labels and stick to fiber-packed foods.
