勿庸置疑，食物在人的容貌和感受以及患病风险方面发挥着举足轻重的作用。有趣的是，在思维方面也发挥着重要作用。最近在欧洲进行的一项研究表明，进食人们通常所吃的三种不同食物对于用来计量认知力的测验分数具有显著影响。
这项研究对2031名七十多岁年长参与者的进食习惯进行了研究。专门观察了他们对三种不同食物——红酒、巧克力和茶的进食量。测定了他们的进食量之后，对他们进行了一系列综合测验，以测量他们的认知能力。发现进食这三种健脑食物量最大者认知测验得分数最高。他们还发现了剂量依赖效应，意为进食这些食物的量越大得分越高。三种食物似乎都提高了测验得分，给人印象最深的是红酒。
为什么这些食物如此特别？
这些食物的共同之处何在？它们都是类黄酮的绝佳来源，类黄酮是一种存在于天然植物中的生化品。具有抗氧化能力。此前的几项研究已表明，类黄酮有助于保护大脑细胞免受与氧化压力有关的伤害，在维护大脑功能方面也许是相当重要的。类黄酮能够预防随自然衰老而出现的脑功能衰退。这些脑健康食品有助于保护脑细胞，也许有助于改善你的思维能力。
你应当将这些健脑食品添加到日常饮食当中吗？
除影响认知功能之外，这三种食品还都表现出某些对人类健康的益处。从癌症预防作用到心脏保护作用，绿茶和红茶都表现出一系列的积极作用，后者作用小一些。研究中，红酒和巧克力二者均表现出心脏保护作用。喝红酒的弊端在于，妇女每天喝红酒超过一杯，可能会增大乳腺癌的风险，而巧克力如果大量食用，则会引起体重增加。然而，日常饮食适量吃一些这类健脑食品也许在各方面都是有益的，可能会改善你的思维能力就是其中之一。
总之，对于改善思维能力和总体健康而言，将这三种健脑食品适量地加入到日常饮食当中，也许是明智之举。
原文:Three Super Brain Foods That Will Help You Think Better
There’s no doubt that
plays an important role in how you look
and feel as well as your risk of developing disease. Interestingly,
it may also play a critical role in how well you think. A recent
study carried out in Europe showed that the intake of three
different, commonly available foods had a significant impact on
test scores that measured cognitive skills. Could these three brain
healthy foods help to improve your thinking skills?
This study looked at the eating habits of 2,031
older participants in their early seventies. They were specifically
looking at how much they ate of t red wine,
chocolate, and tea. After determining their intake of these foods,
the participants were given a battery of tests to measure their
cognitive ability. It was found that individuals who consumed the
greatest amounts of these three brain healthy foods had the highest
cognitive test scores. They also saw a dose dependent effect,
meaning the more of these foods the subjects consumed, the higher
their test scores. Including all three foods in the diet appeared
to elevate the test scores the most with the most impressive
effects seen with red wine.
Why are These Foods so Special?
What do all of these brain healthy foods have in
common? They’re all an excellent source of flavonoids, natural
plant based biochemicals that have anti-oxidant capabilities.
Several previous studies have shown that flavonoids may be
important in maintaining brain function by helping to protect brain
cells against injury related to oxidative stress. It’s been
proposed that flavonoids can potentially help to prevent the
decline in brain function that occurs with natural aging. By
helping to protect brain cells, these brain healthy foods may help
to improve your thinking skills.
Should you Add These Brain Healthy Foods to Your
All three of these foods have shown some
potential health benefits in humans in addition to their effects on
cognitive function. Green tea and to a lesser extent black tea has
shown a variety of positive benefits ranging from cancer prevention
to protective effects on the heart. Both red wine and chocolate
have shown cardioprotective effects in studies. The drawback to red
wine consumption is that drinking more than a glass a day has been
associated with an increased risk of br and
chocolate if eaten in large quantities could cause weight gain.
Nevertheless, adding moderate amounts of these brain healthy foods
to your diet may be beneficial in a variety of ways, including the
potential to improve your thinking skills.
All in all, adding these three brain healthy
foods to your diet in moderate amounts may be a wise move not only
to improve your thinking skill, but for health in
