Older adults in low- to middle-income countries seem to have a lower risk of dementia if they regularly eat fish, according to a new study in the American Journal of Clinical Nutrition.
This comes on the heels of another recent study questioning the anti-dementia protective effect of fish consumption.
Almost 15,000 people were surveyed in China, India, Cuba, Domincan Republic, Mexico, Peru, and Venezuela. As fish intake increased – from never, to some days of the week, to most or all days of the week – dementia prevalence dropped by 19% for each increase of intake. Data for the effect were less convincing for Indian populations.
The prevalence of dementia also tended to rise with meat consumption.
