Side Effects Of Titanium Dioxide-What Does Titanium Dioxide Do To The Body If Eaten
Titanium dioxide (TiO2) is a white, powdery substance that is commonly used as a pigment in paints, plastics, papers, and inks, as well as in sunscreen products to protect skin from ultraviolet light. It is also used as an additive in food as a coloring agent, known as E171.
When ingested in small amounts, as is typically the case with food-grade titanium dioxide, it is generally considered safe. The substance is often used in food products because it is believed to pass through the body without being absorbed. However, recent studies have raised some concerns about the effects of titanium dioxide nanoparticles on the body when eaten.
Here are some potential effects of titanium dioxide when ingested:
1. **Gastrointestinal Effects**: Some studies suggest that titanium dioxide nanoparticles can cause irritation or inflammation in the gastrointestinal tract. There is also a possibility that these particles could accumulate in the gut lining over time.
2. **Absorption and Distribution**: While it was previously thought that TiO2 was not absorbed by the body, newer research indicates that some titanium nanoparticles may be absorbed and could potentially distribute to other organs. The health implications of such distribution are not yet fully understood.
3. **Oxidative Stress**: Nanoparticles of titanium dioxide may generate reactive oxygen species, leading to oxidative stress, which can potentially damage cells and tissues.
4. **Inflammation**: There is evidence that titanium dioxide nanoparticles could trigger an immune response or inflammation, particularly if they reach the liver or other organs.
5. **Allergic Reactions**: In some individuals, titanium dioxide may cause allergic reactions, although this is more commonly associated with skin exposure rather than ingestion.
It’s important to note that the concerns raised by these studies are primarily related to titanium dioxide in its nanoparticle form, which is much smaller than the particles used in traditional, non-nano forms. The health effects may vary depending on the size of the particles, the amount ingested, and the frequency of exposure.
Regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have set safety limits for the use of titanium dioxide in food. However, given the emerging evidence, some consumer groups and scientists are calling for further research and possibly revised regulations regarding the use of titanium dioxide, especially in its nanoform, in consumer products. If you have concerns about titanium dioxide in your diet, it may be helpful to consult with a healthcare professional or a nutritionist.
