The full ingredient list for classic yellow Peeps, in descending amounts:
[1]
SugarCorn syrupGelatinLess than 0.5 percent of the following: Yellow #5 (tartrazine), potassium sorbate (a preservative), natural flavors, and carnauba waxSugar
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.
Corn syrup is made by breaking down corn starch into glucose, creating a thick, sweet liquid. Like sugar, corn syrup is quickly absorbed by the body and can contribute to rapid increases in blood sugar.

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.
It’s a protein derived from collagen, typically sourced from animal skin and bones, usually cows and pigs. That means marshmallow Peeps are not vegetarian or vegan.
[3]
“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)
[1]
[4]
Blue Peeps contain Blue #1
[5]
Yellow #5 and Blue #1 are synthetic dyes derived from petroleum.
[6]
Carmine is a red dye made from dried and crushed cochineal insects. These tiny bugs mainly live on the pads of prickly pear cacti.
[7]
These dyes are regulated by the U.S. Food and Drug Administration (FDA), which considers them safe when used within approved limits.
[8]
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.
Without preservatives, products like Peeps would spoil much more quickly.
[9]
Natural Flavors“Natural flavors” is a broad category defined by federal regulations.
[10]
It refers to flavoring compounds derived from natural sources, such as:
Fruits or vegetablesSpices or herbsPlant 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.
It’s derived from the leaves of a Brazilian palm tree and is commonly used as a coating in candies and other foods. It’s also used in nonfood products like car wax and shoe polish.
[11]
In food, it acts as a glazing agent and is considered safe for consumption in small amounts.
