Inhaled/Ingested Titanium Dioxide crystals may raise type 2 diabetes risk

A study published in 2018 in Chemical Research in Toxicology suggests that ingested titanium dioxide particles may increase risk of type 2 diabetes in addition to early findings that this material can potentially cause various cancers.

Titanium dioxide is commonly used in foods, cosmetic products and supplements.

The study found particles of titanium dioxide in sizes of 110 plus/minus 70 nm diameter are in a large amount in the pancreas specimen from type 2 diabetes patients. This was not found in non-diabetic pancreas specimen.

This pilot study examined 11 pancreatic specimen with 8 from type 2 diabetes patients and three from non-diabetic individuals. All diabetic pancreas specimen were found to have high amounts of titanium dioxide, but not in non-diabetic specimen.

France is banning use of titanium dioxide in foods as studies have shown that titanium dioxide nanoparticles can damage DNA causing carcinogens in animals.

It has been known for a long time that inhaled nano-particles like titanium dioxide and even silicon dioxide can cause lung cancer, which have been recognized by the World Health Organization as human carcinogens.

Ingested nanoparticles can travel to the brain, liver, lung, pancreas and kidney in addition to potentially other organs.

吸入/摄入的二氧化钛可能会增加2型糖尿病的风险

2018年发表在“毒理学化学研究”上的一项研究表明，摄入的二氧化钛颗粒可能增加2型糖尿病的风险。

二氧化钛颗粒被广泛地用在加工食品，美容产品以及保健品。

该研究发现，在2型糖尿病患者的胰腺物种中，大小为直径为110±70nm的二氧化钛颗粒大量存在。这在非糖尿病胰腺标本中未发现。

这项初步研究检查了11例胰腺标本，其中8例来自2型糖尿病患者，3例来自非糖尿病患者。发现所有糖尿病胰腺标本都含有大量二氧化钛，但非糖尿病标本中没有。

法国禁止在食品中使用二氧化钛，因为研究表明，二氧化钛纳米颗粒可以破坏导致动物致癌的DNA。

长期以来已知吸入的纳米颗粒如二氧化钛甚至二氧化硅可引起肺癌，这已被世界卫生组织认为是人类致癌物。

除了潜在的其他器官外，摄入的纳米颗粒还可以传播到大脑，肝脏，肺脏，胰腺和肾脏。
