Why Americans are consuming a sunscreen ingredient in their frozen pizza

  • Titanium dioxide is used in frozen pizzas to enhance color but has raised health concerns.
  • Regulatory agencies like the FDA and EFSA consider it safe within specified limits, but ongoing research suggests potential risks.
  • Consumers should stay informed and read food labels to make healthier dietary choices.

Titanium dioxide stands out for its dual role. Known for its use in sunscreens to protect against harmful UV rays, this chemical also finds its way into our food, particularly in frozen pizzas. This might sound alarming, but understanding the reasons behind its use and the associated health risks can help consumers make informed choices.

Titanium dioxide, or TiO2, is widely used in the food industry to enhance the color of various products. From the pristine whiteness of mozzarella cheese on your frozen pizza to the vibrant hues in candies like Skittles, this additive plays a crucial role in making food visually appealing. However, its presence in food has sparked concerns, especially given its primary association with sunscreen.

Recent research has brought to light potential health risks linked to the consumption of titanium dioxide. Studies, primarily conducted on animals, have suggested that ingesting this additive could lead to immune system disturbances, inflammation, and DNA damage, which might increase the risk of cancer. A small study involving 35 healthy individuals found a link between titanium dioxide consumption and gut inflammation, raising further questions about its safety in food products.

The Environmental Working Group (EWG) has been vocal about the potential dangers of titanium dioxide in food. They argue that certain brands of frozen pizza might contain chemical ingredients that pose health risks. While the EWG's concerns are noteworthy, it's essential to consider the regulatory stance on this additive. The Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have both evaluated titanium dioxide and deemed it safe for use in food, provided it does not exceed 1 percent by weight of the food.

The FDA's regulations on food additives are stringent. They require substantial evidence that a substance is safe at its intended level of use before it can be added to foods. Moreover, all additives are subject to ongoing safety reviews as scientific understanding and testing methods evolve. This regulatory framework aims to ensure that consumers can feel safe about the foods they eat.

Despite these assurances, the debate over titanium dioxide's safety continues. Critics argue that the long-term effects of consuming this additive are not fully understood, and more research is needed to ascertain its impact on human health. For instance, a 2019 review of eight studies on industrial workers exposed to titanium dioxide suggested possible pulmonary and cardiovascular effects, although no causal link was established.

Given the current evidence, it's clear that titanium dioxide's role in food is complex. While regulatory agencies maintain that it poses minimal risk, ongoing research and consumer advocacy highlight the need for continued scrutiny. For consumers, the best approach is to stay informed and make dietary choices that align with their health priorities.

Titanium dioxide's use in frozen pizzas and other foods underscores the broader issue of food additives and their safety. As research progresses, it will be crucial to balance the benefits of these additives in enhancing food quality with the potential health risks they may pose. Until then, reading labels and understanding the ingredients in our food remains a prudent practice.
