Most people know how to keep their body healthy, but not many people think about how to keep their brains(大脑) healthy. Judy is speaking to Dr Fida Cortez, a professor(教授) about brain health.
Dr Cortez: We must eat healthily. One of the best ways for the brain to get energy is from whole grain foods, like bread and rice. They can keep the brain working hard for longer.
Judy: Is fat important? What kind of fat should we eat?
Dr Cortez: The brain needs fat to work well. Fatty acids(脂肪酸) are healthy fats from fish and nuts. Fat from fast food like hamburgers is bad for the brain; it stops the brain using the fatty acids well.
Judy: People talk about berries a lot. Are they a "super food"?
Dr Cortez: Yes, berries are very good for the brain. Blueberries, strawberries and blackberries are full of something called antioxidants(抗氧化剂). They help the brain to stay healthy.
Judy: What about sleep?
Dr Cortez: Sleep is important. It is difficult for your brain to work well if you haven't had enough sleep, and too much sleep is also bad. It can make you feel tired.
Judy: We know exercise is good for our bodies. Is it good for our brain?
Dr Cortez: Yes, exercise is another good way to take care of the brain. It makes the blood move to the brain more easily and quickly.
