Clinical studies conducted by Dr. Emilio albanese and colleagues, published in the American Journal Clinical Nutrition, June 2009, to analyze the impact of fish and meat consumption with the risk of a demensia (senility) in the population in some developing countries.
As a background in clinical studies, to prove the relationship between consumption of meat and fish and risk demensia that is not consistent and does not exist in the population in developing countries. Which is objectively, examining the relationship between the consumption of meat and fish with demensia / senile in countries with low and middle income.

By using the phase 1 survey, a cross sectional assembled on a number of people with age 65 to 11 regions in China, India, Cuba, Dominica Republic, Venezuela, Mexico, and Peru. Total 14.960 person / people in the data using the 10/66 protocol terstandar including face-to-face interview about the eating habits of fish and this is validated with a diagnosis of dementia. Each participant is differentiated in terms of consumption of fish, ranging from never, a few days a week, almost every day and every day that the fish consumed within 1 week.

The researchers said that diet and Feed prevalence varies among demensia place. Researchers mengkombinasi specific place of Poisson Regression prevalence ratios (PRs) to connect between the consumption of meat and fish and demensia in metaanalisa 2 fixed-effect model that has been disesuai the sosiodemografik and health characteristics with the consumption of meat and fish with the right. Relationship found dose-dependent inverse relationship between fish consumption with the occurrence demensia. With PR: 0.81; 95% CI: 0.72, 0.91 which consistently occurred in all places except India and the less consistent, dose-dependent, direct relationship between meat consumption and the prevalence demensia. (PR: 1:19, 95% CI: 1:07, 1:31).


In addition they found that people who frequently consumed meat in the food daily have a higher prevalence for the demensia compared with those who rarely or never consume meat.

From research by Dr. Emilio and his friends, found a decrease in the prevalence demensia / senility about 19% and extend the findings of this case that people who regularly consume fish have a smaller risk akan demensia occurrence compared with those that are less or never consumed fish.
