Corn muffins can be viewed as healthy because of the ingredient used to make them — yellow cornmeal. Yellow cornmeal is the only whole grain to contain beta-carotene, a nutrient processed into vitamin A in the body, making it a nutrient-rich baked good as opposed to most others.  However, when it comes to corn muffins, you must consider the other ingredients involved — sugar, butter, buttermilk, and salt — which may make them not so healthy. You can, however, opt to use whole-wheat flour instead and other options to make this dish healthier.
