吃鱼能够提高记忆,让心情变好

这些鱼都富含欧米茄3脂肪酸--为什么这很重要？因为大脑的60%都是由脂肪构成的，而一半的脂肪都是欧米茄3类脂肪。大脑用欧米茄3脂肪构建大脑和神经细胞，这些脂肪对于学习和记忆至关重要。

Omega-3s have some additional benefits for your brain - they may slow age-related mental decline and help ward off Alzheimer's disease. And they may help make the "good mood" brain chemical, serotonin.

欧米茄3脂肪酸还能给大脑带来其它好处--可能会减缓与年龄相关的精神衰退疾病、帮助抵御阿尔兹海默症。而且还能帮助产生"让心情变好的"大脑化学物质--5-羟色胺。

Not getting enough omega-3s is linked to learning impairments, as well as depression and memory loss. One study found people who ate baked or grilled fish regularly had more grey matter in their brains. And that's the stuff that hosts most of the nerve cells which control decision-making, memory and emotion.

身体没有获得足够的欧米茄3脂肪酸会导致学习障碍以及抑郁和记忆力衰退。一项研究发现：经常吃烤鱼的人大脑中含有更多的灰质。而灰质是控制决策、记忆力和情感的神经细胞密集的部位。

To gain all these benefits, health experts recommend we eat at least two portions of fish each week - one of which should be from the varieties above that are rich in omega-3s. The recommendations are based on a serving of around 140g, that's about 170g before cooking. So if you're only eating small portions - for example half a can of tuna provides around 60g of fish - you may need to eat fish more often.
