In Pollock Communications and Today's Dietitian's annual "What's Trending in Nutrition" survey, 757 registered dietitian nutritionists (RDNs) were polled to determine which ultra-nutrient-dense foods consumers will value in 2023. The top 10 superfoods in the list fit into a plant-based diet for the first time in 11 years of the survey, with kimchi and other fermented foods, such as yoghurt, kombucha tea and pickled vegetables, ranking first. The list comprises seeds, blueberries, avocados, nuts, leafy greens, aquatic greens, green tea, ancient grains and non-dairy kinds of milk. RDNs predict consumers navigating the crisis of higher cost of living will prioritize affordability over immunity for the first time since the pandemic. According to the RDNs, consumers will look for functional, value-based foods supporting their immunity and gut health, making fermented foods the top purchase drivers in 2023.
