Food dyes are substances used to add color to food and beverages. They can be derived from natural sources, such as fruits and vegetables, or created synthetically in laboratories. Common examples include beet juice for red and turmeric for yellow. Food dyes enhance the visual appeal of products and can also help indicate flavor. In many countries, food dyes are regulated to ensure safety for consumption. Some people may have allergies or sensitivities to certain dyes, leading to health concerns. Labels on food products often list the specific dyes used, allowing consumers to make informed choices about what they eat.
