Have you ever wondered exactly how much Red 40 is too much? After receiving numerous questions from listeners concerned about their favorite snack foods, we decided to tackle this question head-on with scientific evidence and practical advice. The answer is more alarming than most would expect. A 2023 research study confirms that Red 40 causes DNA damage, colonic inflammation, and disrupts the gut microbiome in mice. Even more concerning, the rise in early-onset colorectal cancer over the past four decades directly coincides with increased synthetic dye usage in our food supply. These aren't just correlations – they're causal relationships backed by rigorous scientific investigation. While the FDA sets acceptable daily intake values at just 0.7mg for adults, 7.2mg for teens, and 4mg for children, the reality of our consumption is staggering.
