Now a social media influencer who goes by the name the "Farm Babe," Miller says the wind knocked her corn flat on the ground. Hari has published books blasting corruption in the food industry as well as her own cookbooks, and sells subscriptions to her blog. She said that such companies often find it hard to keep up with fast-moving social media trends as they like to vet their partnerships carefully. Scientists say there is not yet a large enough body of evidence to show whether synthetic food dyes cause these problems. West Virginia in March banned some synthetic food dyes from being sold in the state, and Arizona and Utah have recently banned a list of synthetic food dyes in school meals.
