5 Ways to Beef Up Your Brain

[Doz]

1. Eat Your Brain Food

You are what you eat, or at least your brain is. A diet of junk food can junk up your brain, as things like trans fats and saturated fats, common in heavily processed foods, can negatively affect the brain's synapses. Synapses connect the brains neurons and are important to learning and memory. On the other hand, a balanced diet rich in omega-3 fatty acids - found in salmon, walnuts and kiwi fruit - can give the synapses a boost and help fight against mental disorders from depression to dementia.

2. Hit the Gym

Giving the rest of your body a workout can also improve your memory, make you think more clearly and decrease the risk of developing cognitive diseases, several studies have suggested. Because exercise is a mild stressor to your body, eating up the precious energy needed by the brain, it triggers the release of chemicals called growth factors that make the brain's neurons stronger and healthier. Half an hour every other day will do it, experts say. And don't forget to stretch: Stretching can help reduce stress, which can impact the memory centers of your brain.

3. Mind Benders

Give your brain a workout, too, with brainteasers, crossword puzzles and memory games - studies have shown that using these tools to stay mentally active can reduce the risks of developing dementia by building and maintaining a reserve of stimulation in your brain. Even following the current political campaign can provide a boost to the systems that control attention and learning that are hard-wired into the brain.

4. Memory tricks

Keeping information stored in your memory banks and retaining that memory with age may also be a simple matter of mind control. For example, confidence in your cognitive abilities could actually affect how well your memory functions, particularly for the elderly. Because some older adults tend to blame memory lapses on age, regardless of whether or not that is the cause, they can keep themselves from even really trying to remember. Prediction can also enhance memory: If you have a good idea of the information you'll need to recall later, you're more likely to remember it.

5. Give it a Rest

Sleep gives your brain a chance to replay the memories of the day and consolidate them for long-term storage. One study suggested that the brain can do its reviewing much faster when you're asleep than when you're wide awake - so no more all-nighters, students. A 90-minute mid-afternoon nap can even help solidify long-term memories, such as events or skills you are trying to master. Siesta anyone?

Of course, none of these mind-enhancing tips is fool-proof. Some studies have suggested that developing Alzheimer's and other types of dementia is partly a matter of genetics.

One such study, presented in July at the Alzheimer's Association's International Conference on Alzheimer's Disease, hinted at a connection between mothers who develop Alzheimer's and the chances their children will become afflicted in old age. Another suggests that having a specific pattern of proteins is a risk factor for the debilitating disease.

But for now, no one can predict exactly who will or won't develop dementia. While scientists work on better indicators and cures, doing your own part to keep your body and brain healthy is probably the best you can do.

The Right Fats

Evidence is accumulating that a diet that draws heavily on fatty food and only lightly on fruits and vegetables isn't just bad for your heart and linked to certain cancers. It may also be a major cause of depression and aggression. Such a diet is particularly common among men.

The health of your brain depends not only on how much (or little) fat you eat but on what kind it is. Intellectual performance requires the specific type of fat found most commonly in fish, known as omega-3 fatty acids. Even diets that adhere to commonly recommended levels of fats, but the wrong kind, can undermine intelligence. What makes this finding awkward is that certain oils widely touted as healthy for the heart are especially troublesome for the mind.

Omega-3s are known to be particularly crucial constituents of the outer membrane of brain cells. It is through the fat-rich cell membrane that all nerve signals must pass. In addition, as learning and memory forge new connections between nerve cells, new membranes must be formed to sheathe them. All brain cell membranes continuously need to refresh themselves with a new supply of fatty acids. A growing amount of research suggests that the omega-3s are best suited for optimal brain function.

While consuming too much fat overall and too much saturated fat, many North Americans fail to consume enough omega-3s. And the polyunsaturated oils widely recommended as healthful for the heart and widely used in cooking, frying and prepared food—corn, safflower and sunflower oils—have almost no omega-3s. Instead they are loaded with omega-6s. You need a proper balance of omega-6s and omega-3s. Canola oil and walnut oil are highly recommended.

It's possible to boost alertness, memory and stress resistance by supplying food components that are precursors of important brain neurotransmitters. One of them is choline, the fat-like B vitamin found in eggs. Studies show that choline supplementation enhances memory and reaction time in animals, especially aging animals. It also enhances memory in people. Choline supplementation also minimizes fatigue. In one study, choline given during a 20-mile run improved running time by a significant amount...
