I couldn't help but share this study just because it made me laugh. If you know me, you know how I feel about the "low carb" craze. Moderation of refined carbohydrates = absolutely. Completely cutting out the carbs and replacing them with high fat proteins? Not a chance. Today I read an article with the headline: "Low-Fat Diet Makes People Less Angry Than Low-Carb, Study Says", with the corresponding story reporting that of two experimental groups, one low fat and one low carb, participants receiving the low fat diet were much less grumpy and angry than those who restricted their carbohydrates. Both groups were eating the exact same amount of calories, but the low fat group was eating ten times more carbohydrates than the low carb group.

I admit that I haven't read the original study, so I can't comment on the quality of the research, but I just have to agree that when I don't eat carbohydrates, and therefore don't have an adequate amount of glucose (our body's main energy source, and most importantly our brain's main energy source) I get cranky and spacey. And that is no fun for anyone. Bottom line? There is a reason you need to eat carbohydrates. Don't avoid them, be smart about them and be aware of your portion sizes. Whole grains, fruits etc. are good for you and your body needs them to function properly. Avoiding them could lead to other people avoiding you.
