FDA approves 3 natural food colors. Here's what they are and what they can be used for.

The U.S. Food and Drug Administration announced Friday it has approved the use of three color additives from natural sources for manufacturers to safely use in food. The move comes amid growing concerns about the health effects of food dyes, which has led to action at state and national levels.

Last month, Health and Human Services Secretary Robert F. Kennedy, Jr. called on companies to phase out all petroleum-based dyes by the end of next year. Earlier this year, a West Virginia law announced it's plan to ban seven artificial food dyes — one of the most comprehensive statewide bans of its kind.

The food dye industry has denied any safety concerns with artificial dyes. The International Association of Color Manufacturers previously said in a statement that artificial dyes are "essential for consistency, visual appeal, and consumer trust in food products."
