What does yellow 5 in drinks do to your body?

Yellow 5, also known as tartrazine, is a synthetic food dye commonly used in beverages and processed foods to impart a bright yellow color. While it is generally recognized as safe by food safety authorities, some individuals may experience allergic reactions or sensitivities, including headaches or skin rashes. Additionally, there is ongoing debate about its potential links to hyperactivity in children, though research findings are mixed. Overall, moderation is key, and awareness of personal sensitivities is important.
