Food coloring has been in use for a very long time. Unfortunately, there’s no reason to believe that it has become any safer over the years. While many natural alternatives to artificial colorings are available, using artificial coloring likely helps keep the cost of processed foods low, making it all the more appealing to the masses. Potential problems associated with artificial colorings include hyperactivity in kids, worsening ADD or ADHD, allergic reactions and sinus congestion.
