The military has a lot invested in training pilots and decided to fund a study to find out which foods are best for them. The University of North Dakota researchers found the 45 pilots who ate the fattiest foods, such as butter or gravy, had the quickest response times in mental tests and made fewer mistakes when flying in tricky cloudy conditions. Surprisingly, after those on the high-fat diet, those on the high carb diet performed the best, with the worst performance from those on the high protein diet.
