Producers of popular useful spice of turmeric can add to it a lead chromium, capable of having a neurotoxic effect. This was stated by scientists at Stanford University (USA).

American researchers have reported that they have received evidence that some spice producers add industrial pigment pigment to turmeric – this is a cheap and fast way to give it a characteristic yellow tint. Scientists have used isotope analysis: they compared lead isotopes from turmeric with lead isotopes in the blood of humans. It has been found that the consumption of turmeric dishes is the most possible cause of heavy metal in the blood of the inhabitants of Bangladesh. Experts emphasize that the safe limit of heavy metal content in the body does not exist, for nerve cells it is toxic in any volume.
