Food dyes are large molecules that generally cannot cross the blood-brain barrier and have not been shown to affect brain function. Their toxicity is dose-dependent, only presenting risks at very high doses in animals, with no substantial clinical evidence indicating harm in humans. The push to eliminate food dyes lacks scientific justification, primarily serving aesthetic purposes. Despite prevalent misinformation on food dyes and health topics, the truth reveals a complex understanding of these substances.
Food dyes are very large molecules that carry considerable electrical charges, making it hard for them to traverse membranes, especially the ones that protect the brain.
The toxicity of food dyes is dose dependent, with only very high doses showing toxicity in animal studies.
There is no solid clinical evidence showing toxicity in humans and no scientific reason for removing food dyes from the market.
Except for aesthetics, there is no valid reason for dyes to be present in food.
