Turmeric / Curcumin Dye is not Carcinogenic

Turmeric is the source of food color Curcumin, a dicinnamoylmethane dye, E 100. A deep orange-yellow dye. It is included in my list of 11 Natural Food Colorings.

Turmeric belongs ginger family, Zingiberaceae. It is used as spice and as natural food colorant. It is known to havecurcumin dye alert antioxidant and anticancer effects.

But beneficial is not always beneficial. There are reports that curcumin are carcinogenic. It caused hair loss and lowering of blood pressure in animal studies. Caused nausea and diarrhea during human clinical trials. Found to alter iron metabolism leading to iron deficiency.

European Food Safety Authority (EFSA) concludes that curcumin is not carcinogenic. This is in accordance with the findings of World Health Organization (WHO) and Food and Agriculture Organization (FAO). They also found out that the food additive is not genotoxic,  capable of  DNA damage resulting to mutations or cancer. They set an acceptable daily intake (ADI) of 3mg/kg bw/day.

However, there are no other review about other suspected side effects.
