A、Potatoes. B、Egg yolk. C、Cereals. D、Tea. B本题考查重要细节。根据句(9)可知，鸡蛋、蛋黄和大豆都能创造通道帮助大脑吸收营养和排除毒素，所以说它们很重要，每天都需要吃，因此[B]为正确答案。

W: Well.(6- 1)Healthy fats, believe it or not, are great for coping with stress, such as nuts, seeds, olive, olive oil and etc. A great stress buster: peanuts and peanut butter.
M: Yes.
W:(6-2)And then again, dairy foods are great. They help reduce stress and decrease anxiety and anger. And so again,(6 - 3)combinations get in protein and vitamin B6. So lean beef and turkey are good choices. Making yourself a turkey sandwich on the whole-grain bread seems a great idea.
M: OK, our final mood here is energetic.(7- 1)How to be energetic? People who we interviewed also showed their preference to something with sugar, as candy bars or a protein shake. OK, now I mean we all do it. Sugar, caffeine, you know.
W: Right.
M: Are any of those unharmed?
W: Well.(7-2)There are some good ones there. The liquid is really critical. So water, of course is very good.
M: Keeping yourself hydrated.
W: Keeping yourself well hydrated.(8)There’s nothing more important for all of your moods than to keep yourself drinking plenty of water. But there are other things, such as eggs and soy.(9)The egg, the egg yolk and soy are fast food fat that actually creates channels to allow nutrition into the brain and poisonous substances out. It’s so important to have them in your diet everyday. And of course, everyone loves chocolate. But we can also have coffee, tea, a little bit of caffeine. They are stimulant.
M: So it’s a pick-me-up in the morning. It’s great before exercise. You don’t want too much, because it can make you feel lousy rather than better.
W: Or too late in the day.
