Does a daily dose of dhal dispel dementia?
The Daily Mail reported today that “eating a curry once (or twice) a week could stave off dementia.”
Sadly, this mouth-watering headline is not a good representation of the research. The study in question tested the effects of curcumin (a chemical found in the spice turmeric) on fruit flies. It found that curcumin improved lifespan and activity in some genetically engineered fruit fly models of Alzheimer’s disease. However, some other fruit flies, including the normal fruit flies, those eating actually died more quickly.
This type of study is essential for the initial testing of chemicals that may be of some benefit to humans. Chemicals showing beneficial effects and sufficient safety in animal studies need to be tested in humans before we can know what their true effects on a disease are. However, the promising effects of many chemicals seen in animals are not replicated in humans.
