And What’s its Connection to Cognitive Functioning?

Red dye No. 3 is used to give food its rich red color and make it appear more appealing to eat. Think sprinkles on donuts, frosting on cake and red hard candy. Sadly, it’s a marketing tool that costs consumers their health. Research has shown that Red No. 3 can cause cancer in animals and has been a long-standing concern for human consumption.

Food with preservatives complicate the way humans function, physically and cognitively. Children are especially taken by the fun colors of bright sweets and other dyed foods. However, their little brains are also more susceptible to its effects, such as hyperactivity, inattention and changes in mood. This can become problematic for their learning. It can also cause parents to fear their children might have long-standing cognitive or behavioral difficulties related to attention and learning.

Adults are also affected by preservatives such as Red Dye No. 3, with similar symptoms as children. However, we may more easily identify the source of the change. No matter a person’s age, however, it’s harmful. The good news is that diet change can cause a rapid and positive improvement.

Here’s the thing though. Although it was reported that it’s now being banned, Red Dye No. 3 will still be available in some foods until early 2027 and in some drugs until 2028. Therefore, it’ll be important to continue to read labels and make sure you’re not buying something that contains Red Dye No. 3.

Because who needs preservatives?
