美國(guó)緬因大學(xué)研究人員的一項(xiàng)發(fā)現(xiàn)，每天飲用至少一杯牛奶,，不僅可保證人體所需的關(guān)鍵營(yíng)養(yǎng),，而且能改善大腦功能。
研究人員日前在《國(guó)際乳品期刊》（International Dairy Journal）上發(fā)表的報(bào)告說(shuō),，牛奶或奶制品攝入量較高的成年人,，在記憶及其他大腦功能測(cè)試中得分較高，他們?cè)跍y(cè)試中“不及格”的比例僅為不飲或少飲牛奶者的五分之一,。
研究人員對(duì)900多名23歲至98歲的成年人進(jìn)行了8項(xiàng)大腦功能測(cè)試,，并記錄他們的牛奶消費(fèi)習(xí)慣。他們發(fā)現(xiàn),，不管在哪個(gè)年齡段,，每天至少喝一杯牛奶的人在測(cè)試中的得分均較高；得分最高的一部分人也包含在飲用牛奶最多的人群中,。
排除生活方式,、飲食習(xí)慣等可能影響大腦健康的因素后，多喝牛奶與大腦更健康之間仍存在關(guān)聯(lián),。研究人員表示,，牛奶中的某些營(yíng)養(yǎng)成分可能直接影響大腦功能，不過(guò)仍需進(jìn)一步確認(rèn)多喝牛奶的益處,。

Relation between dairy food intake and cognitive function: The Maine-Syracuse Longitudinal Study
G.E. Crichton, M.F. Elias, G.A. Doreb, M.A. Robbins,
Diet modification to alter the course of age-related cognitive decline is becoming increasingly important. Few observational findings suggest that dairy food intake may be positively related to cognitive function, but research in this novel area is limited. The aim of this study was to investigate whether dairy food intake is associated with cognitive function, before and after adjustment for cardiovascular, lifestyle and dietary factors. To do this, a cross-sectional analyses of a subset of the community-based Maine-Syracuse Longitudinal Study (MSLS) sample (N = 972) was undertaken. It was determined that participants who consumed dairy products at least once per day had significantly higher scores on multiple domains of cognitive function compared with those who never or rarely consumed dairy foods, adjusting for cardiovascular risk factors, lifestyle and dietary factors. Frequent dairy food intake is associated with better cognitive performance but underlying causal mechanisms are still to be determined.
