Summary

Dr. Sunil Dhand discusses titanium dioxide (E171), a fine white pigment used in some foods. It has no nutritional value and may be found in products such as sweets, baked goods, sauces, spreads, icings, and coffee creamers. Dhand shows ingredient labels for Trolli Sour Brite Crawlers and Skittles that list titanium dioxide.

The video contrasts U.S. policy with restrictions and safety concerns elsewhere. Dhand says the FDA still permits titanium dioxide in food, while European authorities no longer consider it safe as a food additive and France has banned its use in food. He also argues that U.S. food policy is overly influenced by industry interests.

Research and concerns cited

Dhand refers to research raising questions about possible health effects:

  • A 2021 review of animal studies examined titanium dioxide’s effects on gut microbiota. The authors noted that it is difficult to apply animal findings to humans, but highlighted the gut microbiome’s relevance to nanoparticle toxicity and called for discussion about safe use.
  • A 2020 review reported that titanium dioxide nanoparticles may cause inflammation through oxidative stress and may have genotoxic effects, including apoptosis or chromosomal instability.
  • A 2021 study on orally administered food-grade nanoparticles discussed gaps in available toxicity data and the need for further research, including into possible cancer-causing effects from long-term accumulation in the colon.

Dhand presents these findings as reasons for caution while acknowledging that some evidence is based on animal research and that further study is needed.

Practical advice

  • Read ingredient labels and look for “titanium dioxide” or “E171.”
  • Check the ingredients in foods you buy.
  • Avoid products containing the additive where possible and aim for a less processed, more natural diet.
  • Pay particular attention to products marketed to children, which Dhand says may contain concerning additives.
