Understanding Artificial Food Dyes

Artificial food dyes are synthetic chemicals used to enhance the color of food, beverages, medications, and cosmetics. Studies have linked many of these dyes to various health issues, including hyperactivity in children, allergic reactions, and even cancer in lab animals.
