avoid-synthetic-dyes
The podcast detailed the prevalence of synthetic dyes in products marketed to kids—28% of children's foods contain them versus 19% of foods overall. Dr. Mike Malin explained that red and yellow dyes are most studied for links to inattention and hyperactivity, but all synthetic dyes are suspect. Bryan Johnson read a list of top offenders with specific milligram amounts: Target mini green cupcakes (55.3 mg), Kool-Aid Burst Cherry (52 mg), Captain Crunch Oops All Berries (41 mg), Skittles (33 mg), etc. Mike shared that his son experiences behavioral changes from dyes and now self-polices, saying 'I don't eat blue foods.' The group recommended making dye avoidance a family rule, similar to a sleep culture, and educating kids on why these colors are harmful. Kate noted that Kraft Heinz has pledged to remove all synthetic dyes by 2027, showing that consumer pressure works. The easy path is to check for Red 40 and Yellow 5 on labels; the hard path is to eliminate all ultra-processed foods.
Synthetic dyes are petroleum-derived chemicals that can cross the blood-brain barrier and may disrupt neurotransmitter function, leading to hyperactivity and attention deficits. Some are also genotoxic, potentially causing cellular damage and increasing cancer risk. The exact mechanisms are still being studied, but the correlation with behavioral issues is strong enough to warrant avoidance.
Mike: 'my son um is does seem to have some behavioral changes with um with the synthetic dyes, and we taught him very young to avoid certain color foods. And like he actually pays attention to it. ... He's like, "Oh, I don't I don't eat blue foods."' Bryan: 'I sat my kids down and I tried to use various tactics to explain how bad ingredients negatively affected the things they cared about.'
Synthetic dyes are colorings that are additive um added to many food products but like disproportionately added to children's products. The ones that we're thinking of typically are the red and yellow dyes and those have been linked directly to uh inattention and to um hyperactivity disorders.
