LONDON, Jul 21, 2009 (UPI via COMTEX) -- A study involving 14,960 participants
age 65 and older found increased fish consumption is associated with lower
dementia risk, a British researcher says.
The survey of older people was carried out at 11 sites -- one urban and one
rural in Peru, Mexico, China, and India and in urban sites only in Cuba, the
Dominican Republic and Venezuela. More affluent areas of the countries were
avoided.
Dietary habits were assessed by using standard, culturally appropriate
face-to-face interviews and dementia was diagnosed by using validated culturally
and educationally fair criteria.
In each of the study countries, except India, there was an inverse association
between fish consumption and dementia prevalence. These data extend to low- and
middle-income countries previous conclusions from industrialized countries, that
increased fish consumption is associated with lower dementia prevalence in later
life, says first author Emiliano Albanese of King's College London.
The findings are published in the August issue of the American Journal of
Clinical Nutrition.
