大型的流行病學研究證實:食用魚類對老年人腦部有幫助
 
在一份橫跨多國的研究中顯示,攝取魚類有助於降低癡呆症的發生率。專家指出,在全世界有超過2千四百萬的人口患有癡呆症並分布在低至中低收入國家。近年來,油脂豐厚的魚類和肉類對於癡呆症的影響有更進一步的研究。在油脂豐厚的魚類中豐富的長鏈不飽和脂肪酸對老年癡呆症有正面的幫助。相反的,一些研究指出大量的攝取肉類會加速癡呆症的惡化。
 
Large Epidemiologic Study Supports Brain Power of Fish in Older People
 
Summary:In each of the study countries, except India, there was an inverse association between fish consumption and dementia prevalence.
20/07/09 Experts estimate that over 24 million people worldwide suffer from dementia, and many of these people live in low- and middle-income countries. Recently, there has been growing interest in whether dietary factors, particularly oily fish and meat, might influence the onset and/or severity of dementia. Oily fish are rich in omega-3 long-chain polyunsaturated fatty acids, which some studies suggest are positively related to cognitive function in later life. Conversely, there is a suggestion from some studies that increased meat consumption may be related to cognitive decline. To examine this, a group of international researchers studied older people in 7 middle- to low-income countries. The results of their study can be read in the August 2009 issue of the American Journal of Clinical Nutrition.

Data from 14,960 participants (≥65 y of age) living in China, India, Cuba, the Dominican Republic, Venezuela, Mexico, and Peru were analyzed. 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. The authors propose that this relation is not due to poor overall nutritional status in those with dementia, because meat consumption tended to be higher in this group. The relation between meat consumption and dementia remains unclear.
