Then how does curcumin work?
Curcumin has shown to possess anticancer effects by blocking the transformation in the body. The low incidence of colon cancer among Indians has been attributed to the use of turmeric in Indian cooking. In addition to its immunity-boosting, anticancer effects, curcumin has been effective against a variety of conditions such as reduction in blood sugar and improvement of type-2 diabetes.
Curcumin appears to suppress oxidative damage, inflammation, cognitive deficits, and amyloid accumulation in Alzheimer’s disease. It also appears to show protective effects in cystic fibrosis, viruses, and treat alcoholic liver disease.
As with any nutrients from food, you need to be able to digest and absorb them. Curcumin is not easily absorbed and needs a catalyst. With cooking, combining turmeric with black pepper makes it more bioavailable.
