We Asked 3 Nutritionists to Name the Best Cereal Brand—They All Picked the Same One

If eating cereal brings you back to the simpler times of childhood, you’re not alone. The breakfast staple is nostalgic, delicious, and most of all—fun! However, if you want to get the most out of cereal, it’s worth being mindful of conventional versions.

The reason? “Traditional cereals are often ultra-processed, low in protein and fiber, and rely heavily on refined grains and added sugars,” explains registered dietitian Samantha Peterson, MS, RD. This combo can spike your blood sugar first thing in the morning (assuming you’re eating the cereal for breakfast), setting you up for an energy crash and more cravings later in the day, she notes.

Over time, the rapid rise and fall of blood sugar levels can lead to fatigue and hunger soon after meals, shares registered dietitian Seema Shah, MPH, MS, RD. They can also contribute to long-term health consequences, including prediabetes, type 2 diabetes, heart disease, and other cardiometabolic issues, Shah points out. Plus, “some traditional cereals contain artificial ingredients and additives, along with surprisingly high sodium amounts, which are not great for our health,” Shah explains.

Now, there’s nothing wrong with occasionally enjoying your favorite “fun” cereal. But if you’d like to prioritize nutrition, you may want to eat healthier varieties more often. What do those cereals look like, exactly, and is there a brand that experts recommend? To find out, we asked dietitians to share the top features of a better-for-you cereal, along with their go-to brand.

What to Look for When Buying Cereal

When shopping for cereal with nutrition in mind, here’s what experts recommend looking for:

Added Sugar

This is a big one. Whereas traditional cereals tend to be higher in the added sugar department, healthier varieties are usually lower. Aim for a cereal with 5 grams (or less) of added sugar per serving, suggests longevity dietitian Ella Davar, RD. That’s because high sugar intake is the biggest driver of energy crashes, cravings, and poor metabolic health, Davar notes.

Protein

“Choose cereals with at least 5 to 8 grams of protein [per serving] to help balance your morning and extend fullness,” Davar says.

Fiber

Look for a cereal with 3 to 5 grams of fiber per serving, suggests Davar. “Fiber supports gut health, satiety, and stable blood sugar,” she explains. 

Healthy Fats

If possible, Davar recommends picking a cereal with nuts, seeds, or coconut. These ingredients contain healthy fats, which contribute to satiety and manage inflammation.

Whole Ingredients

“Prioritize whole-food, minimally processed ingredients. Avoid artificial sweeteners, dyes, and preservatives,” Davar says. According to Shah, whole grains should be the first ingredient on the label.

Serving Size

“The serving size listed on the nutrition label can sometimes be smaller than what you consume,” Shah says. Thus, she suggests converting the nutritional facts to the amount that you’re actually eating.

Finally, if you have a GI condition, look for a gluten-free or grain-free variety. “Many people with digestive issues do better with oat-, nut-, or seed-based blends,” explains Davar.

What Is the Healthiest Cereal Brand?

The next time you shop for cereal, consider the factors listed above. Alternatively, if you’d rather get an expert recommendation, you’re in luck: When asked to name their favorite healthy cereal brands, all three dietitians called out Seven Sundays.

“Seven Sundays stands out because it focuses on real, nutrient-dense ingredients rather than the ultra-processed grains and additives common in traditional breakfast cereals,” Davar explains. “Seven Sundays is much closer to a functional food than a conventional boxed cereal,” she adds.

More specifically, the brand does an excellent job balancing protein, healthy fats, and fiber, something you rarely see in the cereal aisle, Peterson notes. This combo is “genuinely supportive of metabolism, hormone health, and lasting fullness in a way that fits real life,” Peterson adds. Plus, Seven Sundays products are not only nutritious and well-balanced, but delicious too, per Shah.

If you’re new to Seven Sundays, here’s a specific recommendation from each dietitian:

• Seven Sundays Oat Protein Cereal: “This cereal uses oats as the star ingredient, delivering a naturally high-fiber, whole-grain base with added oat protein to make it more filling than traditional cereals,” explains Peterson. Plus, unlike most cereals, it has a short recognizable ingredient list, low added sugar, and balanced macros that keep you satisfied, Peterson adds.
• Seven Sundays Blueberry Almond Real Food Cereal: Featuring whole almonds, blueberries, and oat clusters, this cereal is high in fiber and naturally sweetened, according to Davar. It also offers a great balance of carbs, fat, and protein, a combo that can keep blood sugar stable, she adds.
• Seven Sundays Classic Bircher Apple Cinnamon Muesli: With gluten-free oats listed as the first ingredient, this cereal is appropriate for gluten-free diets. It’s also high in fiber and protein and low in total sugars. This makes it a “nourishing and tasty option for breakfast that will give you sustained energy and balanced blood sugar levels throughout the morning,” explains Shah.

Remember: You don’t need to give up your favorite childhood cereals to be healthy. Instead, enjoy them as the occasional treat, and focus on healthier versions (like those from Seven Sundays) for your daily bowl.
