The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein, fat, 100,000 miles of blood vessels and 100 billion nerve cells, it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks.
Its complexity are stunning, far beyond anything most of us can imagine. To keep this work of art as polished as possible we need to eat right, exercise and keep mentally stimulated.
Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It's very important that we tell people to be physically active and mentally active,” said neurologist Malcolm Stewart.
“People cannot stop aging, but you're able to reduce the damage; you're able to keep the function up.”
Following are Dr.Stewart's advice for improving brain health:
Nutrition
Avoid fast food. Follow the old adage(格言): For breakfast, eat like a king; for lunch, like a
queen; for supper, like a beggar.
Exercise
Do a combination of stretching aerobic and musclestrengthening every day.
Mental games
