In America, a child cannot imagine growing up without having Skittles, it is the country's most iconic candy. In other news, it has been announced that it will no longer contain titanium dioxide, an ingredient that has faced criticism over potential health risks. The parent company Mars has confirmed after the rising public scrutiny of food additives and its ban in the European Union. It has announced it phased out titanium dioxide from US Skittles products at the end of 2024. However, the company did not mention if the reformulation affects Skittles that is being sold outside the US. As per the Mars spokesperson and reported by BBC, "All our products are safe to enjoy and meet the high standards and applicable regulations set by food safety authorities around the world.:What Is Titanium Dioxide?It is a white pigment which is used to make food appear brighter and more visually appealing. Most common of its used can be found in candies, baked goods, chewing gum, and cosmetics and paint. As per a 2011 study published in Radiology and Oncology, titanium dioxide is considered as an inert and safe material and has been used in many applications for decades. However, notes the study, with the development of nanotechnologies, its nanoparticles with numerous novel and useful properties are increasingly manufactured and used. Thus, increased human and environmental exposure can be expected, which puts its nanoparticles under toxicological scrutiny. The study also notes that based on experimental evidences from animal inhalation studies, nanoparticles are classified as "possible carcinogenic to humans" by the International Agency for Research on Cancer and as occupational carcinogen by the National Institute for Occupational Safety and Health. The Center for Science in the Public Interest, titanium dioxide can potentially accumulate in our bodies and is associated with health risks such as DNA damage and immune system toxicity. The European Union has banned its use in foods due to such safety concerns. A safety evaluation by the European Food Safety Authority (EFSA) found that evidence suggests that when humans ingest food-grade titanium dioxide, small particles of titanium dioxide can accumulate in human body over time and can cause genetic damage. This could also cause cancer and other health problems. What Does The FDA Say?The US Food and Drug Administration (FDA) say that titanium dioxide is safe to use in foods and personal care products, however, it provides strict guidelines on how much can be used in food. The limit is very small: no more than 1% of it can be used.

The main use of titanium dioxide is as a barrier to keep the sun's ultraviolet (UV) rays from damaging your skin. It is also processed into much smaller particles than what goes into your food. Thus, in this form, it becomes transparent and absorbs UV light so it does not reach your skin.
