高加工和包装食品从天然食物中移除了重要营养，并用糖、脂肪和盐取而代之。这就是我们所谓的依赖方便食品和快餐的西式饮食。我们理解，人们很忙，有时候没办法自己做酱汁、调料、面条和烘焙食品。

However, it is important to cook with whole nutritious foods as often as you can swing it, because the Western diet is notorious for causing an accumulation of fat around the vital organs. This, in turn, is associated with damage to the brain tissue and a reduction in the brain’s volume. It may also cause disruptions to the blood-brain barrier, the membrane that is responsible for protecting the brain from harmful substances.

但是，只要你能腾出空来，你应该尽量自己多做全营养食品，因为西式饮食会导致脂肪在重要器官周围积聚，进而对大脑组织造成损伤，降低脑容量，也许还可能破坏血脑屏障，血脑屏障是保护大脑不被有害物质侵入的薄膜。

5. Alcohol 酒精

It’s probably no surprise that alcohol can harm the brain, considering how much stupid stuff people tend to do under the influence. Getting tipsy every once in a while probably won’t cause permanent damage, but alcoholism and bouts of binge drinking absolutely can.

酒精会损害大脑，这可能并不让人意外，你只需要想一想人们在酒精的影响力下都干了多少蠢事。偶尔小酌也许没事，但是酗酒绝对会造成永久性大脑损伤。
