Team Butter has been empowered by recent health studies about its benefits to set a pick on its margarine opponent and drive for the hoop. In the 52 weeks ending Aug. 12, 2018, dollar sales for butter jumped 5.8%, while unit sales rose 1.8%, Chicago-based market research firm IRI reported.

Consumers used to think that low-fat diets and margarine were better for their health, but recent research has shown that natural sources of fat, including butter, are beneficial, explained Venae Watts, fifth-generation owner of Minerva Dairy in Minerva, Ohio. She points out that popular diets, including the keto diet, encourage daily intake of fatty foods, including butter, for healthy, natural fuel.
