Frozen yogurt has long been marketed as the healthier cousin of ice cream. In the 1990s, chains like TCBY promoted it as a low-fat, low-calorie treat with “all of the pleasure, none of the guilt.” Today, many frozen yogurt shops advertise probiotics and gut-health benefits.
The dessert is making a comeback. According to the International Frozen Yogurt Association, about 129 new frozen yogurt shops opened in the United States over the past year, a nearly 50% increase from the year before. Social media has helped fuel the trend, with long lines at popular shops and homemade frozen yogurt recipes attracting millions of views.
But nutrition experts say frozen yogurt’s healthy reputation deserves a closer look.
Unlike ice cream, which by law must contain at least 10% milk fat, frozen yogurt has no federal standard defining how much yogurt or fermented dairy it must contain. Recipes vary widely from one brand to another. Some products contain cultured yogurt or fermented milk, while others may contain relatively small amounts along with sugar, flavorings and other ingredients.
That means buying frozen yogurt doesn’t necessarily provide the same nutritional or digestive benefits as eating a cup of plain yogurt.
Like most commercially sold ice cream, much of the frozen yogurt sold in stores and self-serve shops is also considered ultra-processed. They both contains added sweeteners, stabilizers and emulsifiers that improve texture and keep ice crystals from forming. Diets high in ultra-processed foods have been linked to higher risks of obesity, heart disease and Type 2 diabetes.
Frozen yogurt generally contains fewer calories and less saturated fat than ice cream. However, manufacturers often add extra sugar to balance yogurt’s naturally tangy flavor, leaving many frozen yogurt products with sugar levels similar to—or even higher than—ice cream.
Some frozen yogurt brands do contain live probiotic cultures that may support digestive health. But researchers say it’s unclear whether frozen yogurt provides the same gut-health benefits as regular yogurt because freezing and processing can reduce the number of living bacteria. Products carrying the “Live & Active Cultures” seal are more likely to contain meaningful amounts of those beneficial microbes.
Experts say the healthiest choice often comes down to portion size and toppings. Candy, cookie crumbles and sugary syrups can quickly erase any calorie or fat advantage frozen yogurt may have.
The bottom line: Frozen yogurt can be a slightly lighter dessert than ice cream, but it isn’t automatically a healthy food. If you’re looking for the proven nutritional benefits of yogurt, plain yogurt is still the better choice. If you’re simply looking for a sweet treat, experts say either dessert can fit into a healthy diet when enjoyed in moderation.
