Most breakfast cereals are predominantly refined grains and added sugar. And quite often a cereal that looks healthy is not. Learn what to look for when choosing a healthier breakfast cereal and what ingredients to avoid.
Criteria to consider when choosing breakfast cereal:
1. Look for fiber and whole grains
Breakfast cereals are made from processed grains. All grains are predominantly carbohydrates, which are broken down by the body into sugar. Whole grains include all three parts of a grain: the germ, endosperm and bran.1 Fiber, a key component of most whole grains, slows down the rate the body digests carbohydrates keeping you fuller longer. The FDA recommends consuming at least 25 grams of dietary fiber a day and the American Heart Association states that “dietary fiber from whole grains, as part of an overall healthy diet, may help improve blood cholesterol levels, and lower risk of heart disease, stroke, obesity and type 2 diabetes.”2,3
2. Minimize refined grains
Refined grains have some portion of the grain removed (typically the bran and germ, sources of the majority of a grain’s vitamins and fiber).1 Depending on the food and how processed it is, the speed with which the body digests the carbohydrates is highly variable. Highly processed carbohydrates (like those in most breakfast cereals) are broken down extremely quickly and can rapidly increase blood glucose levels. Foods that rapidly increase blood glucose levels are known as high Glycemic Index (GI) foods.4 Diets comprised predominantly of high-GI foods are associated with chronic disease and strongly associated with heart disease.4
3. Minimize added sugar
The amount of added sugar varies widely across different cereal types and brands, though most breakfast cereals could be considered vitamin fortified cookies. Added sugar has many different names. In cereal, typical added sugars listed in the ingredients include sugar, cane sugar, corn syrup, brown sugar syrup, honey, brown sugar, molasses, fructose, and dextrose. Read more on recommended daily intake of added sugar and why you want to minimize added sugar consumption.
4. Avoid artificial preservatives
Many breakfast cereals use vitamin E, a natural preservative, to maintain “freshness.” However, some cereal brands use butylated hydroxytoluene (BHT), a synthetic antioxidant that, while considered safe by the FDA, is considered by the US Department of Health and Human Services to have carcinogenic potential.5 With non-synthetic antioxidants readily available (such as tocopherol), it is advisable to avoid foods that contain BHT.
5. Avoid artificial food coloring, including caramel color
Artificial food coloring is most widely used in sodas, candy, and baked goods. A recent study published in the journal Clinical Pediatrics found that more than 40% of food products marketed to children contained artificial food coloring.6 Though considered safe by the FDA, some children have been found to have negative reactions to artificial food coloring.7 Additionally, many common artificial food dyes have been shown to cause allergic reactions in sensitive people.8 Though only small amounts of artificial coloring are used in baked goods, such as cereal, it is advisable to avoid products that contain any artificial food coloring. We discuss why it is best to avoid caramel coloring in a previous post on choosing a granola bar.
Bottom line: choose a breakfast cereal that is mostly whole grains rich in fiber, has minimal added sugar, and contains ingredients you recognize.
Evaluation of top selling breakfast cereals
The top 10 selling breakfast cereals were evaluated using the criteria below.9 Many cereals rich in whole grains could not be rated as “wise” simply because they contained too much added sugar. This is a very common problem with breakfast cereal.
It is worth noting that “avoid” does not mean never eat. It simply means that these are cereals that contain mostly, if not all, refined gains, enough sugar that they should be classified as a dessert, and often other junky ingredients. These cereals should be considered a rare treat (or even dessert) and not a breakfast staple.
Criteria used to evaluate popular breakfast cereals
Since cereal serving sizes can vary widely from ~ 27 to 60 grams, all information below is for 30 gram servings. The total percent added sugar is included to highlight just how much sugar is added to top selling breakfast cereals. Also included are the total grams of whole grain and fiber per serving. Types of added sugar are listed in red. Ingredients to be concerned about are bolded. Finally, an asterisk (*) indicates ingredients that are likely genetically engineered (learn more about GMO foods).
Choosing Healthier Cereals
Though most of the top selling breakfast cereals contain some whole grains, they are almost all loaded with added sugar. In fact, most of the cereals contain half of the American Heart Association’s recommended daily intake of added sugar for children! When you choose a healthier cereal for your family, try to select one that is 100% whole grains with minimal added sugar.
How do you know if a cereal is rich in whole grains? Look to see if “whole grain ____” is the first ingredient on the ingredient list or if the cereal contains roughly 1 gram of fiber for every 10 grams of carbohydrates listed on the Nutrition Facts label.
Healthy top selling breakfast cereals:
None of the top selling cereals are what we would consider healthy. This is partially because almost all cereals contain highly processed grains. When cereal grains are processed into flakes, circles, and puffs, our bodies can digest the carbohydrates quickly, resulting and increases their GI value.4,10
Healthier cereals do not contain added sugar, are less processed, and have sufficient amounts of fiber to help slow down how quickly our bodies can digest them. A few examples of healthier cereals are listed at the end of this article.
Cereals that are okay for occasional eating:
Ingredients: whole grain oats, corn starch, sugar, salt, tripotassium phosphate, vitamin E. 11
Are you surprised to see Cheerios rated as a cereal to eat only “occasional”? Even though Cheerios contain 100% whole grain oats, they are NOT 100% whole grain. The second ingredient in Cheerios is corn starch. Our bodies rapidly metabolize starch into sugar, which causes a rapid spike in blood sugar levels.4,10
Is it okay to feed your children Cheerios? Yes. And the oats used in Cheerios are certified gluten free, so they are a good option for people who have gluten sensitivity issues. However, because they are highly processed and considered a high glycemic index food, they should not be an every day meal or snack.
Cereals to avoid or eat only as a rare treat:
Honey Nut Cheerios
Ingredients: whole grain oats, sugar*, oat bran, corn starch*, honey, brown sugar syrup, salt, trisodium phosphate, rice bran oil and/or canola oil*, natural almond flavor, vitamin E.12
Ingredients: milled corn*, sugar*, malt flavor, salt, and BHT.13
Honey Bunches of Oats
Ingredients: corn*, whole grain wheat, sugar*, whole grain rolled oats, brown sugar*, almonds, rice, canola oil*, wheat flour, malted barley flour, corn syrup*, salt, whey, malted corn* and barley syrup, wildflower honey, caramel color, cinnamon, natural and artificial flavor, annetto extract.14
Cinnamon Toast Crunch
Ingredients: whole grain wheat, sugar*, rice flour, canola oil*, fructose, maltodextrin, dextrose, salt, cinnamon, trisodium phosphate, soy lecithin*, caramel color, and BHT.
Ingredients: corn flour blend* (whole grain yellow corn flour, degerminated corn flour), sugar*, wheat flour, whole grain oat flour, oat fiber, modified food starch*, hydrogenated vegetable oil*, oat fiber, salt, soluble corn fiber*, natural flavor, red 40, turmeric extract color, blue 1, yellow 6, annatto extract color, and BHT.
Ingredients: whole grain oats, sugar*, oat flour, corn syrup*, modified corn starch*, corn starch*, dextrose, salt, gelatin, trisodium phosphate, yellows 5 & 6, red 40, blue 1 and other color added, natural and artificial flavor, vitamin E.
Frosted Mini Wheats
Ingredients: Whole grain wheat, sugar*, brown rice syrup, gelatin, and BHT.
Ingredients: Whole grain wheat, raisins, wheat bran, sugar*, brown sugar syrup, salt, malt flavor.
Note: It is unclear exactly how much of the sugar in Raisin Bran is natural sugar from the raisins and added sugar. Updated labeling requirements by the FDA (to come into effect in early 2020) should help clarify this.
Raisin Bran is another cereal that is often considered a healthy choice. This is probably because of the whole grain flakes and raisins. However, Raisin Bran contains hidden added sugar in both the sugar coating on the raisins and in the flakes. A wiser choice would be to purchase bran flakes that are low in added sugar and simply add in raisins.
Examples of healthy breakfast cereals:
To understand what healthier options for breakfast cereal look like, it is important to look past the top selling brands. Top selling cereals are positioned at eye level on a grocery shelf, so look to the top or bottom shelves for healthier options. Below are a few examples of wise and occasional breakfast cereal options.
Post Shredded Wheat, Spoon Size
Ingredients: whole wheat.20
Kashi 7 Whole Grain Puffs
Ingredients: whole hard red wheat, whole brown rice, whole oats, whole barley, whole triticale, whole rye, whole buckwheat, sesame seeds.21
Example healthier cereals for occasional eating:
365 Bran Flakes
Ingredients: whole wheat, wheat bran, cane sugar, barley malt extract, sea salt.22
Ingredients: Corn flour, whole grain oat flour, cane sugar, oat fiber, corn bran, unsulfured molasses, sea salt, baking soda, vitamin C, vitamin E. 23
Conclusions about breakfast cereals
Breakfast cereals are typically high glycemic index (GI) foods because of the highly processed grains and excessive amounts of added sugar. By choosing a cereal that is less processed with no added sugar, you are able to reduce the GI of a food. This is important because there is increasing scientific evidence that suggests that elevated blood glucose levels after meals contributes to the development of chronic disease.24 Also, research has shown that people who eat high GI breakfasts tend to eat more calories later in the day.
So what does my family eat for breakfast? On mornings when we have cereal, we eat a combination. Everyone starts with a good helping of my homemade granola, which is often topped with some puffed grains or other no-added-sugar cereals and a sprinkling of more treaty “occasional” cereals.
