Carbs might be bad for your waistline, but it's thought that they might be good for you're brain, or at least that's what this article seems to say. In a study involving people who followed a high-fat/low-carb plan and those who followed a high-carb/low-fat plan, those in the latter group were the ones who showed improvement to their cognitive processing when given a series of tests.

But other than that, researchers found few other differences between the two groups -- their moods were about the same, and members from both groups were still losing weight.

What do you think of these findings? Me, I'm surprised that mood wasn't more of a factor -- I've heard of low-carb diets causing massive mood swings.
