The year was 1988 and, apparently, everyone was hungry, because the state meal consists of: fried okra, squash, cornbread, barbecue pork, biscuits, sausage and gravy, grits, corn, strawberries, chicken fried steak, pecan pie, and black-eyed peas. Just how many calories is that? If you ate the average serving size of each item listed, you'd consume about 2,200 calories. And about 260 grams of carbohydrates, 90 grams of fat, 70 grams of protein and 3,700 milligrams of sodium.
