The Daily Mail and Daily Telegraph reported that eating a curry weekly could help to “stave off dementia”. Researchers tested the effects of curcumin (found in turmeric) on fruit flies (Drosophila melanogaster) genetically engineered to have a model of Alzheimer’s Disease. They found it improved the lifespan and activity in some of these flies (while others died more quickly).
Note: This animal research is at an early stage and cannot be taken as a firm indication that eating a weekly curry would prevent Alzheimer’s Disease or other dementias in humans. The newspaper headlines, while attention grabbing, are not properly representative of the actual research.
