Curcumin, the polyphenol that gives turmeric its tang and yellow hue, has anticancer properties, anti-inflammatory effects, and tumor-fighting activities known in nutritionspeak as anti-angiogenesis. Researchers at UCLA have also found that it helps deter the accumulation of amyloid plaques in the brain, tiny blockages that may cause Alzheimer’s disease. Turmeric’s prevalence in India, the researchers suggest, may help explain why so few of the country’s senior citizens have the disease, whereas the statistic is close to 13 percent in the United States, according to the Alzheimer’s Association. One tip: Pair it with pepper in curries. “Adding black pepper to turmeric or turmeric-spiced food enhances curcumin’s bioavailability by 1,000 times, due to black pepper’s hot property called piperine,” says nutritionist Stacy Kennedy of the Dana Farber Cancer Institute.
