The Trump administration's decision to abandon its attempt to ban artificial dyes could complicate the issue, as food dyes are known to cause health problems such as hyperactivity and sleep disruptions. Food manufacturers have been asked to remove six synthetic, petroleum-based food danes from their products. Thomas Galligan, principal food additives and supplements scientist at the Center for Science in the Public Interest, stated that these additives can cause acute behavioral problems in children and impact children's academic and social success. He argued that marketing, not nutritional value, is the primary reason for these additives being kept on shelves in American grocery stores.
