Is Titanium Dioxide Safe? Skittles Pulls Ingredient After Health Warnings
New Delhi:
Skittles, the colourful candy known for its "taste the rainbow" slogan, will no longer include titanium dioxide in its US product lineup. Mars Wrigley, the parent company of Skittles, said the ingredient was phased out by the end of 2024.
Though it was never banned by US regulators, the additive has long been under scrutiny for potential health risks.
What Is Titanium Dioxide?
Titanium dioxide has long been used by candy manufacturers for its ability to enhance colours and give sweets a smooth, shiny, and appealing finish.
In candies, titanium dioxide acts as a whitening and brightening agent. It is also used in chewing gums, mints, powdered donuts, cake decorations and even toothpaste. Its job is purely aesthetic. It makes colours pop and gives products a consistent, clean appearance.
Health Concerns Associated With Titanium Dioxide
The European Food Safety Authority (EFSA) conducted a comprehensive review in 2021 and concluded that titanium dioxide could no longer be considered safe as a food additive.
The conclusion was based on evidence suggesting titanium dioxide particles, especially in nanoparticle form, could accumulate in the body and potentially cause DNA damage, a process known as genotoxicity. Such damage may lead to chromosomal alterations and increase the risk of cancer.
Based on this, EFSA declared titanium dioxide unsafe for use in food. Animal studies also linked it to immune system damage, inflammation, and possible effects on the brain.
The International Agency for Research on Cancer (IARC) classifies titanium dioxide as "possibly carcinogenic to humans" based on inhalation studies in animals.
As a result, the European Union banned titanium dioxide in food in 2022.
The US Food and Drug Administration (FDA) continues to permit titanium dioxide in foods, provided it doesn't exceed 1 per cent of the product's weight.
Organisations like the Center for Science in the Public Interest (CSPI) have petitioned the FDA to ban the component in foods, citing health risks.
How To Avoid Titanium Dioxide In Food
Read ingredient labels: Look for "titanium dioxide" on the packaging. Sometimes it may be listed as "artificial colour", "E171," or "colour added."
Go organic: Certified organic foods are not allowed to contain titanium dioxide or other artificial colours.
Limit ultra-processed foods: These often contain many additives, including titanium dioxide. Choose fresh or less-processed foods when you can.

US approves new lower-dose COVID-19 vaccine made by Moderna
The US approved a new COVID-19 vaccine made by Moderna late Friday but with limits on who can use it — not a replacement for the company's existing shot, but a second option. The new vaccine, mNexspike, is a step toward next-generation coronavirus vaccines. It's made in a way that allows for a lower dose — a fifth of the dose of its current COVID-19 vaccine, Spikevax — by refining its immune target. The approval 'adds an important new tool to help protect people at high risk of severe disease from COVID-19,' Stephane Bancel, Moderna's CEO, said in a statement Saturday. The Food and Drug Administration approved the new vaccine for use in all adults 65 and older, and for people age 12 to 64 who have a least one health condition that puts them at increased risk from the coronavirus. That's the same limit that the FDA set in licensing another COVID-19 vaccine option from competitor Novavax. Those restrictions are a departure from how the US has handled COVID-19 vaccines until now, reflecting skepticism about vaccines from Health Secretary Robert F. Kennedy Jr. and other Trump officials. Moderna's existing vaccine doesn't face those limits and has long been used for anyone ages 6 months and older. The company said it expected to offer both options this fall. The FDA's approval was based on a study of 11,400 people age 12 and older that compared the new low-dose vaccine with Moderna's existing vaccine. It found the new vaccine was safe and was at least as effective — and more by some measures — than the original shot, the company said. The news came just days after the Trump administration canceled funding for Moderna to develop a vaccine against potential pandemic flu viruses, including the H5N1 bird flu, despite promising early study results.

Is your sunscreen really protecting you? A new report reveals alarming truths behind that SPF label
As temperatures rise and beaches fill, most of us reach for the familiar tube of sunscreen, trusting it to be our shield against the sun's wrath. But a startling new report suggests that this trust may be misplaced. According to the Environmental Working Group's (EWG) 2025 Annual Guide to Sunscreens , a staggering majority of products lining U.S. store shelves may not be offering the protection they promise. In fact, fewer than one in four of the 2,200 SPF products evaluated met the organization's criteria for safety and effectiveness. Misleading Labels and Murky Regulations The report casts a harsh light on sunscreen manufacturers and regulatory bodies alike, accusing them of misleading claims and failure to update decades-old standards. Since 1999, federal sunscreen regulations have remained largely unchanged, leaving consumers at the mercy of marketing jargon and obscure ingredient lists. 'Many sunscreens still fall short,' the EWG warns, 'by offering misleading claims about protection and using outdated formulas—some even containing ingredients with potential health concerns.' Among the biggest culprits? Aerosol sprays, which make up 26% of all SPF products in 2025. Although the FDA proposed safety testing for these in 2019 due to inhalation risks and patchy application, it has yet to finalize these rules. Between 2021 and 2023, multiple sunscreen sprays were recalled due to benzene contamination, a known carcinogen—yet the market remains flooded with these popular but problematic products. The Fragrance Trap Another eyebrow-raising concern: undisclosed 'fragrances.' The report reveals that 36% of sunscreen products containing unspecified fragrance ingredients actually hide a cocktail of allergens, hormone disruptors, and even carcinogens. A 2022 federal law mandated the FDA to outline clear guidelines on fragrance allergens by July 2024. But as of May 2025, no such guidelines have been proposed. EWG attributes the delay to regulatory staffing shortages under the Trump administration, further complicating consumer safety efforts. Until transparency improves, the organization urges consumers to seek fragrance-free sunscreens or those bearing the EWG Verified® mark, which signifies ingredient clarity and the absence of harmful additives. The Fall of Oxybenzone and Vitamin A Some silver linings have emerged. Once a common ingredient in non-mineral sunscreens, oxybenzone has seen a dramatic fall from 70% usage in 2016 to just 9% in 2025. The compound is flagged not only for disrupting hormones but also for damaging marine ecosystems—a serious double threat. Vitamin A (often listed as retinyl palmitate) is another ingredient on the decline, found in only 2% of sunscreens today, down from 41% in 2010. Despite its skin-nourishing reputation, Vitamin A can degrade in sunlight, potentially worsening skin damage rather than preventing it. iStock Experts now urge consumers to opt for fragrance-free, mineral-based options and reapply frequently for real protection. (Representational Image: iStock) The Safer Path to Sun Protection So, what should a sunscreen-savvy shopper do in this minefield of misleading products? The EWG guide doesn't just criticize—it also educates. The top advice includes not falling for high SPF labels, which often give a false sense of security. Products boasting SPF 50+ may only offer marginally better protection than SPF 30, while encouraging users to stay in the sun longer than is safe. The guide recommends lotion or stick sunscreens over sprays, choosing mineral-based formulas with ingredients like zinc oxide, and using physical barriers like hats, sunglasses, and long-sleeved clothing. And perhaps most importantly: reapply often, especially after swimming or sweating. Sun safety is about more than what's in the bottle. With skin cancer rates rising, knowing what goes on your skin—and into your body—has never been more crucial. This summer, before you bask in the glow of sunshine, take a closer look at what you're trusting to guard your skin. The truth behind your SPF might not be as radiant as you think.
