There are certain things you think of as "junk food," but even foods that you might not think of as junk food can still be bad for you. These foods include items that are processed, fried, oily, and contain lots of simple carbohydrates like sugar and starch.
Be aware that your parents may have taught you bad dietary habits. Many people enjoy their soul food or cultural menus, but neglect to realize that these foods may be rich in fats, oils, and empty calories. Review your recipes and try to remove excess oil, butter, frying, and the like. You will improve your diet while retaining your heritage.
