If curcumin can really help prevent heart disease, cancer, and Alzheimer’s disease, it may also be good for longevity. Numerous studies show that curcumin can help treat arthritis symptoms and in some cases is more effective than anti-inflammatory drugs. Curcumin has a positive effect on several factors known to play a role in the development of heart disease. Curcumin increases levels of the brain hormone BDNF, which promotes the growth of new neurons and may help fight various degenerative processes in the brain. Curcumin can cross the blood-brain barrier and has been shown to lead to a number of improvements in the Alzheimer’s disease process. Whether curcumin can slow or even reverse the progression of Alzheimer’s disease in humans is currently unknown and remains to be investigated. Curcumin does have antioxidant effects, but more research is needed to confirm these benefits. Whether high doses of curcumin – preferably with an absorbent such as piperine – can help treat cancer in humans remains to be studied in detail.
