For years, scientists have already been telling us that the balanced diet can enhance our overall fitness and well-being. In addition, there are several foods which can be constantly advertised as ‘’brain food’’, in that, they can improve cognitive function and brain health. In case that you’re not familiar with them though, lets go over some of the most well-researched and beneficial ones.

1.  Salmon: research shows that Omega-3 fatty acids are essential to cognitive function, and the body cannot manufacture these kinds of fat itself, so you have to get your Omega-3s from food or supplement sources. There are all types of health things to contemplate for various populations, if you’d plan to know more, you can read up on it here. But the main idea is, there’s a large amount of scientific evidence showing that foods loaded in Omega-3 fatty acids truly do feed your brain.

2. Nuts and seeds: foods like flaxseed and walnuts pack identically types of Omega-3 punch that salmon does, and have the extra benefit of providing fiber, which aids to maintain physical health in many means.

3. Blueberries: there’s evidence showing that people who eat a cup of blueberries per day perform 5 to 6% better than a control group does on a test of motor skills. Furthermore, many studies show that the antioxidants in blueberries can help to reverse age-related reductions in cognitive function, such as loss of memory. Plus they create a pretty tasty pie

Now, here’s the vast news: for a few days before taking your GMAT, you might want to move off from your usual healthy diet and indulge a bit.  Were not advocating an overall fast food pig-out;you still need to make sure that you get the typical required amounts of nutrients, and don’t overdo it in the calories, as that it can make you sluggish.  But a study revealed in September 2009 point out that eating too much high-fat diet for four to seven days before an intellectually strenuous task can have a useful affect performance. The study, titled “Nutritional Effects on Cognitive Performance”, was reported by researchers at the John D. Odegard School of Aerospace Sciences, which is a division to the University of North Dakota at Grand Forks, and produced results which were astonishing to many.

The study tested pilots on a full-motion flight simulator, and also measured their short-term memory. Four varieties of diets were tested: high fat, high carbohydrate, high protein, and balanced. The researchers found that pilots on the high-fat diet constantly out-performed those on the other diets: 27% better than the high protein group and 10% greater than the balanced group, with less essential margins over the high carb group. The high carb group also out-performed the high protein group by 22%, and pilots on the high protein diet reported feeling irritable and having a problem in sleeping.

What does this mean for you?  Well, if you’re planning to go to business school, it’s not likely that you’ll be piloting an airplane in the near future.  However, most of the cognitive functions used by pilots-short term memory, quick decision-making, and multi-tasking-will are essential to you on the test day. The message here ISN’T to forgo healthy eating for months of carbohydrate and fat-loading. But for a number of days before the test, it may not be a bad idea to have a little extra butter on your bread, and some gravy on your potatoes. After all, every little bit helps.
