“curcumin may help the macrophages to clear the amyloid plaques found in Alzheimer’s disease.”
Wow! While no one is claiming that curcumin cures Alzheimer’s, this is an important finding.
Curcumin in an ingredient of the turmeric root, which you can buy in your grocery store and use in cooking. In fact, in India cuisine, it accounts for the yellowness in curries and may be the reason why there is a lower risk of Alzheimer’s in India.

Curcumin has many other effects related to the brain health besides clearing amyloid.
The article summary states …
“A growing body of evidence indicates that oxidative stress, free radicals, beta amyloid, cerebral deregulation caused by bio-metal toxicity and abnormal inflammatory reactions contribute to the key event in Alzheimer’s disease pathology. Due to various effects of curcumin, such as decreased Beta-amyloid plaques, delayed degradation of neurons, metal-chelation, anti-inflammatory, antioxidant and decreased microglia formation, the overall memory in patients with AD has improved.”
