Health influencers made cottage cheese so popular that companies are struggling to produce it fast enough. Once thought of as a kitschy diet food, lumpy bumpy cottage cheese is seeing an unprecedented rise in demand thanks to health influencers on TikTok. Cottage cheese sales in the U.S. jumped 20% year over year, according to data from Circana. Cottage cheese is high in protein, low in sugar, and "appropriate for a GLP-1 diet," reports CNN. "Organic Valley Cottage Cheese is selling faster than we can make it," Andrew Westrich, marketing manager at Organic Valley, told CNN.
