Studies show that Titanium Dioxide nanoparticles adversely affect Ca²⁺ATPase levels in the brain, heart, skin, sperm, and epithelial cells when exposed to UV rays.
Check food labels for titanium dioxide in the ingredient list.
Look for vitamins and supplements that do not contain titanium dioxide.
Avoid sunscreen and make-up products that contain titanium dioxide nanoparticles.
Especially avoid aerosol spray sunscreens with this ingredient. Also avoid lip balms.
Food: If you start looking at your food labels, titanium dioxide is everywhere. It is used to add color to various items such as the condiments mayonnaise, horseradish, and mustard. It is used in confectionery sugar, custard, puddings and sherbet and sorbet. Cottage cheese, American cheese, processed deli meats, chocolate milk, battered fish or poultry, processed snacks, and even vitamins and supplements often contain titanium dioxide.
Today, we often use a smaller version of titanium dioxide, so small in fact, that it’s reduced to nanoparticle size. To put this in perspective, one nanoparticle ranges from 1-100 nm. A human hair ranges from 80,000 to 100,000 nms wide. So, with a steady hand, you could place about 1,000 nanoparticles on the end of a strand of hair. Pretty small indeed. Most labels do not reveal what size titanium particles are used.
The problem is, with particles this small, they more easily enter our bodies, traveling into our blood stream and potentially causing harm. Public health and environmental advocates have questioned the wide-spread use and safety of titanium dioxide nanoparticles, and some recent studies indicate that titanium dioxide nanoparticles are toxic to the brain, heart, lung, liver, ovary, testes, spleen, and kidneys of animals. Wow what a list! Unfortunately, children are particularly susceptible to titanium dioxide nanoparticle exposure because of its use in candy. Various candies, chewing gum, and even toothpastes contain the whitening agent. In 2015, Dunkin’ Donuts announced that it would no longer use powdered sugar containing titanium dioxide nanoparticles to whiten its donuts.
Kids are especially vulnerable to consumption because of amounts of titanium dioxide in many snack foods. Remember these add up.
Here are a few examples: M&M chocolate candy; Trident white peppermint gum; Dentyne ice peppermint gum; Mentos; Hostess powdered donuts; Good and Plenty Candy; Kool-Aid Blue Raspberry and Lemonade; Jell-O banana cream pudding; Betty Crocker whipped cream frosting; Mother’s oatmeal iced cookies; Nestle coffee creamer; Pop Tarts vanilla milkshake flavor.
Sunscreen and cosmetics: Titanium dioxide also acts as a sunscreen by reflecting damaging ultraviolet light rays. You might remember life guards at the beach or pool sitting in the sun all day long with a finely whitened nose. That was regular-sized titanium dioxide particles, which are considered safe. The problem arises when nanoparticles are used. These nanoparticles can be absorbed into skin cells (bad idea considering skin cancer associated with reduced Ca2+ATPase). Furthermore, recent studies show that a portion of sunscreen ingredients may penetrate into the bloodstream, which is just now being fully examined.
