What’s Really in Marshmallow Peeps — and Are They Bad for You?

Marshmallow Peeps are a quintessential Easter candy — brightly colored, sugar-coated, and instantly recognizable. Those adorable chicks and bunnies are as much a sign of springtime as a daffodil, whether you’re obsessed with them or just love the memories of the little guys popping up in your holiday basket.

But viewed through adult eyes, you may have questions about whether it’s really okay to eat Peeps, nutritionally speaking. Just what are you or your children ingesting when you eat these light and airy treats with their otherworldly glow?

Here’s a closer look at what’s in Peeps — and what you’re really getting with each bite.

Peeps are almost entirely made up of carbohydrates, specifically added sugars, with little to no fiber, fat, or meaningful vitamins and minerals, says Beril Hezer, RD, a senior registered dietitian with Banner Health in Phoenix.

• Sugar
• Corn syrup
• Gelatin
• Less than 0.5 percent of the following: Yellow #5 (tartrazine), potassium sorbate (a preservative), natural flavors, and carnauba wax

Sugar

Sugar is the main ingredient in Peeps and the primary source of calories. It is rapidly absorbed into the bloodstream, leading to a quick spike in blood sugar followed by a drop shortly after, Hezer explains.

Sugar provides sweetness and structure, but nutritionally, it’s considered an added sugar — meaning it contributes calories without essential nutrients, she says.

Just one serving of Peeps can deliver close to 60 percent of the suggested daily limit of added sugars, Hezer notes, making it “a big chunk in a very small package.”

Corn Syrup

The second major ingredient in Peeps is corn syrup. Beyond adding sweetness, it helps give Peeps their soft, chewy texture. It’s considered about the same nutritionally as common sweeteners like table sugar and honey.

Gelatin

Gelatin gives Peeps their airy, marshmallow-like structure, trapping air to create a light, spongy texture. Gelatin is also the key ingredient in Jell-O.

“While gelatin does contain protein, it’s not a complete protein and doesn’t meaningfully change the nutritional profile of the candy,” Hezer says.

Dyes

Food dyes give Peeps their signature bright colors — yellow, pink, and blue.

• Yellow Peeps use Yellow #5 (tartrazine)

• Pink peeps use carmine color

• Blue Peeps contain Blue #1

For most people, there’s no need for concern about ingesting small amounts of these dyes, says Hezer. “However, some individuals — particularly children — may be sensitive to certain dyes, with possible behavioral effects or mild reactions in rare cases,” she says.

Hezer’s “practical advice”: You don’t need to panic about these additives, just try to limit how frequently you eat them.

Potassium Sorbate

Potassium sorbate is a food preservative that helps prevent mold and extend shelf life.

It’s widely used in packaged foods and is considered safe by the FDA in small amounts.

Natural Flavors

It refers to flavoring compounds derived from natural sources, such as:

• Fruits or vegetables
• Spices or herbs
• Plant or fermentation products

Manufacturers are not required to disclose exactly what these flavors are, so the specific source isn’t always clear.

For most people, natural flavors are not a health concern, though they may matter for people with allergies or dietary restrictions.

Carnauba Wax

Carnauba wax gives Peeps their slightly glossy finish.

In food, it acts as a glazing agent and is considered safe for consumption in small amounts.

The ban is based on a long-standing federal rule that prohibits additives shown to cause cancer in humans or animals, even if the risk at typical exposure levels is unclear.

Peeps provide quick energy from sugar, but don’t offer nutrients to help keep you full or support overall health, Hezer says.

That said, eating a few Peeps occasionally is unlikely to have a meaningful impact on health, she says.

“Portion control is key. It’s easy to overeat foods like Peeps because they’re small, sweet, and not very filling,” says Hezer.

Peeps aren’t a source of meaningful nutrition — but they’re not meant to be. “Peeps are best thought of as a treat,” says Hezer.

As with many things, a balanced approach works best, Hezer says: If you or your kids love Peeps, have just a couple and try to blunt any sugar spike with a meal that offers protein or healthy fats.

• Peeps are mostly sugar, offering quick energy but no nutritional value.
• A single serving can make up more than half the daily added sugar recommendation.
• They’re fine as an occasional treat — just keep portions small and don’t overdo it.
