Red dye 40, otherwise known as Allura Red, is an artificial food coloring made from petroleum products. While it's commonly used in many processed foods, drinks and sweets for added color, there are a few key reasons why you should avoid this ingredient. Firstly, allergy sufferers may experience reactions to red dye 40, such as hives. Some other allergy symptoms are swelling, itching, and difficulty breathing. Furthermore, children are particularly susceptible to these allergy symptoms because their immature immune systems make them more prone to reacting to allergens.
In addition to allergy risks, red dye 40 is also linked to hyperactivity in children. Studies have suggested that certain food colorings, including red dye 40 can lead to hyperactivity. Finally, red dye 40 has been found to cause cancer in laboratory animals and can be toxic if ingested in large quantities. Given these risks, it's best to avoid products that contain Red Dye 40 where possible.
