Because... (taken from OT fitness and nutrition, diets thread)

"Old Fashioned Oatmeal — Make no mistake about it, oatmeal is the carb of choice for many bodybuilders. Even if you’re on a reduced carb diet, there’s nothing wrong with a serving of oatmeal (27g of carbs) to go along with your morning protein. Your body has been deprived of food all night, so some slow-acting carbs to replenish stores, plus some protein, make for a great bodybuilding breakfast.

Oatmeal has about three grams of natural unsaturated fats, five grams of protein, and two grams each of soluble and insoluble fiber. The fiber not only helps keep your pooper working properly, the soluble variety can help improve cholesterol levels, thus earning the American Heart Association’s "heart healthy" seal of approval.

Only buy oatmeal that lists "100% natural rolled oats" in the ingredients. That’s it! Oats should be the one and only ingredient. Do not purchase those individually packaged, flavored oatmeal products! (More on that in our "Bad Stuff" section.) Also, don’t screw up a good thing by adding milk and sugar. Eat your oatmeal like a man. And by the way, old fashioned oats cook up just fine in the microwave, no need to boil the water in a pot.

Oatmeal rocks. Make it a staple of your diet."
