Fiber is the new protein!? The top 5 health trends for 2026 according to registered dietitians

SALT LAKE CITY — Every January we get hit with a wave of predictions, including in the health and nutrition world. Some are backed by science, some fueled through social media, but which trends are actually worth your attention? KSL health contributor Miki Eberhardt asked a collection of registered dietitians to share their insider take on what's coming in 2026. She shared what's resonating with real people trying to eat better.

Fiber Takes Center Stage

Fiber is emerging as one of the most significant nutrition trends for 2026. “I do think fiber will take center stage,” Eberhardt said. “It helps with gut health, it helps with blood sugar management and weight management, keeps us fuller longer and cholesterol control." She explained that fiber in the early 2000s focused on additives while the shift this year emphasizes whole‑food sources of fiber. “The update is real foods for the source. Real food fiber,” Eberhardt said. She emphasized increasing fiber intake slowly and making sure to drink lots of water.

A Shift Towards Plant Protein

Protein remains a staple in health trends moving into 2026. While protein‑packed snacks and beverages continue to expand, experts are noting a shift in where protein comes from. “Where I see, and experts are seeing this trend shift for 2026 is more plant‑based proteins,” Eberhardt said. Plant sources are less expensive and nutritionally beneficial. “Number one, more budget‑friendly than animal‑based proteins,” she said. "And number 2, back to that fiber. If I'm including more beans and quinoa and other things ... Whole foods, higher in fiber."

GLP‑1 Medications Shape Food Choices

GLP‑1 medications are influencing how people eat and how foods are marketed. “The influence of these medications on our food behaviors cannot be denied,” Eberhardt said. She said she expects foods labeled as “GLP‑1 friendly” are expected to increase, but to still be cautious with them. She also explained that people on these medications can be malnourished. “It’s not standardized in any way,” she said. "So become very label literate. And if you need to, pull in a dietician to really make sure you're getting the nutrients you need."

AI Expands Personalized Nutrition

Technology is playing a larger role in nutrition, from fitness trackers to meal planners. “Many dieticians are predicting that personalized nutrition will continue to thrive, if not be boosted by AI and tech,” Eberhardt said. Tools like wearables and meal‑planning platforms may be helpful, but she said not to rely solely on technology as it can still be a little clunky. “There’s a reason why on every platform you use there is the warning, ‘Don’t use this for health or medical advice,’” she said. Eberhardt said that if you do like to use AI to boost your health, run the information you get past an expert to make sure it's correct.

Creatine Moves Into the Mainstream

Creatine is no longer limited to gym culture. “This is kind of going from bro science to, like, the everyday consumer,” Eberhardt said. "We're seeing the research done on everyday people and the benefits that can come from it as well." While it doesn’t directly build muscle, creatine can help you lift more weight for longer. Research is also exploring the cognitive benefits of creatine. "Emerging research on the brain health. I think we'll see more of that come out this year," Eberhardt said.
