Brain foods that help you concentrate
Ginseng, fish, berries, or caffeine?
Listen to the buzz about foods and dietary supplements, and you'll believe they can do everything from sharpen focus to enhance memory, attention span, and brain function.
But do they really work? there's no denying that as we age, our body ages right along with us. The good news is that you can improve your chances of maintaining a healthy brain if you add 'smart' foods and drinks to your diet.
Caffeine can make you more alert
There's no magic bullet to boost IQ or make you smarter -- but certain substances, like caffeine, can energize you and help you concentrate. Found in coffee, chocolate, energy drinks, and some medications, caffeine gives you that unmistakable wake-up buzz though the effects are short-term. And more is often less: overdo it on caffeine and it can make you jittery and uncomfortable.
Sugar can enhance alertness
Sugar is your brain's preferred fuel source -- not table sugar, but glucose, which your body processes from the sugars and carbs you eat. That's why a glass of something sweet to drink can offer a short-term boost to memory, thinking, and mental ability.
Have too much, though, and memory can be impaired -- along with the rest of you. Go easy on the sugar so it can enhance memory without packing on the pounds.
Eat breakfast to fuel your brain
Tempted to skip breakfast? studies have found that eating breakfast may improve short-term memory and attention. Students who eat it tend to perform better than those who don't. Foods at the top of researchers' brain-fuel list include high-fiber whole grains, dairy, and fruits. Just don't overeat; researchers also found high-calorie breakfasts appear to hinder concentration.
