Simply put, good nutrition provides you brain with quality materials to build quality brain circuits. Poor nutrition provides your brain with junk to gunk up the system. Over time, good nutrition enhances brain function and poor nutrition increases the chance that brain circuits will break down and lead to dementia.

This is not going to be an article about all the good foods you should eat and the stuff you should avoid. Many articles, including some of my own, have already beaten that horse. Most people know that carrots are better than cheeseburgers and I'm not going to get into that again at this time. What I want to do instead is give you a different perspective on the value of nutrition in improving and maintaining brain fitness – and what that really means.
Data supports the value of healthy foods for improving performance on intelligence tests and for reducing the risk of Alzheimer's disease and other dementias. Foods like fruits, vegetables, red wine (or moderate use of other alcohols), chocolate, soy protein, fish, olive oils, and others you have heard about, seem to help your brain.
We don't know what we don't know
The difficulty comes when scientists try to break down these foods and purify the specific natural chemicals responsible for their good effects. Usually, these types of experiments fail, although there are a few successes. But do you really care that it's the polyphenols in fruits or the bisdemethoxycurcumin in tumeric that seem to be the active players? It's not like your going to take some blueberries into your home chemistry lab and isolate the ‘most important' ingredient – you're just going to eat a handful of blueberries.
Imagine an alien coming down to Earth and trying to figure out what the most important part of a car is. Is it the wheels, the spark plugs, the axle, what? Obviously, all these parts work together to make the car drive and none of them work without the others. You don't need to understand how an internal combustion engine works in order to drive your car from point A to point B.
The real value of quality nutrition comes from all of the good foods working together. Usually when we try to take them apart, the effect disappears. I'm all for high quality multi-vitamin supplements and take them daily myself. However, when you see all of the ads for highly purified specific components touting to improve your memory, your sex life or whatever you have to be careful. We simply don't know enough yet about all the different healthful components of our food. Any good nutritionist or reputable nutrition company will tell you that supplements are never substitutes for a quality diet.
When it comes to brain fitness, good nutrition is simply the way to supply raw materials to the brain so that it can do the job it is designed to do. Eat the right stuff and let your brain work it out. All of the foods listed above contain hundreds or thousand of different kinds of molecules that the brain uses to run smoothly. There is no single ingredient that is better than everything else.
Good food for good thoughts
The more quality materials you give your brain, the better it works. That translates to clearer thinking, better problem solving and increased intelligence and IQ. The more junk you give you brain, the more you gunk it up and that leads to lethargy, increased odds for dementia later in life and a general feeling of blah today – it's that simple.
You have heard all the healthy food advice in the past. You know what's good for you and what's not. If you want to get smarter now and keep your brain sharp into your older years then quality nutrition is something you need. If you don't care about maintaining your brain function then don't worry about it. One of my favorite pieces of advice that I have heard is "only brush the teeth you want to keep".
Here's another way to think about it. The brain is constantly undergoing construction and demolition. You are building new circuits and taking old ones down all the time. If you are using high quality building materials and have quality tools (through good nutrition) then your new circuits will be stronger and last longer. As we age our construction equipment and tools age as well. But if we keep our repair shops stocked with quality raw materials (good nutrition) then we keep our tools in good working condition and continue to build good circuits. If we don't (poor nutrition) then our construction equipment and tools begin to fail, our circuits don't get built correctly, we start to forget things, don't feel as sharp as we used to and we increase our chance of dementia.
Nutrition is a key part of the brain fitness formula. Simple errors in judgment about what to eat today, compounded over time can only lead to regret. Whereas, simple disciplines today to eat good stuff will lead to life-long vibrant brain health.
Two Support Systems That Keep Your Brain FitYour personality traits may be contributing to your leve
Your personality traits may be contributing to your level of risk for developing cognitive dementia. How well you handle stress and how frequently you interact with circles of friends may be clues to your future, new research tells why.

Traumatic experiences can lead to intrusive memories that haunt you for a long time. Researchers have found one approach to disrupt those memories from solidifying in your mind and make it less likely to suffer the 'flashbacks' of the horrible event.
BrainFit or Bust
Physical exercise is good for your body, but it's also good for your brain. New studies show how a group of fit older women have better blood flow to the brain and perform better on all kinds of cognitive tests, including memory, processing speed and verbal abilities.
