Brain Food

For speedier afternoon thinking, which snack would you choose - a slice of watermelon or a chunk of cheese.

Reach for the watermelon - People who eat foods that are high in healthy carbs but low in fats (watermelon and other fruits being juicy examples) seem to have faster brain processing speeds than people whose diets are low in carbs but high in fats.

Carbohydrates are a critical source of the type of energy that brains need to perform. Fat on the other hand seems to gum up your mind.

If there is no fruit to be found, then try turning on all your office lights or even better, go outdoors and get a dose of natural light. Light directly affects areas of your brain that are involved in alertness.
