Whole Foods predicts that fiber will be the top food trend of 2026, as more fiber-rich products like pastas and breads are appearing on shelves. Research shows that demand for dietary fiber is increasing due to consumer awareness of digestive health and preventive healthcare. Fiber is essential for gut health and is associated with a lower risk of colon cancer, lower cholesterol, and lower blood pressure.

In addition to the rise of fiber-rich foods, the trend of beef tallow is also gaining popularity, driven by low-carb and carnivore diets on social media. Nutritionists express concern about the high saturated fat content of tallow, which can increase the risk of heart disease. Other food trends for 2026 include whole food sweeteners, vinegar, and high-quality frozen foods. Whole Foods Market anticipates that these trends will shape conversations in kitchens and communities in the coming year.
