An interesting paper for you published in the Journal Of Psychopharmacology earlier this month.
Apparently doses of curcumin, the main curcuminoid found in the South Asian spice turmeric, are able to improve “sustained attention and working memory tasks” in 60-85 year olds one hour after ingestion compared to a placebo. It is also claimed curcumin was able to improve working memory and mood following 4 weeks of treatment and associated it with a significant reduction in total and LDL cholesterol.
The researchers suggest that further investigation should be carried out. I would have to agree, it sounds a little bit too good to be true at the moment. But as a curry lover I would be very happy if this was confirmed by other studies.
The paper is available from the Journal Of Psychopharmacology website.
