Country-style home-cooking chain Cracker Barrel does not share ingredients or nutritional facts, but you may still be able to estimate the nutritional content of its apple bran muffins by pairing the nutritional content of a bran muffin and cooked apple. Since many restaurants offer larger portions than those that would be made at home, considering the nutritional facts associated with a large bran muffin is appropriate.
Count the Calories
One large oat bran muffin provides around 375 calories. A cooked apple that weighs 100 grams -- or around 3 ounces -- adds another 56 calories. People who eat an apple bran muffin from Cracker Barrel, then, could expect to eat a total of around 431 calories.
According to the USDA's Nutrient Database, each large oat bran muffin provides around 67 grams of carbohydrates, six of which are in the form of dietary fiber. A cooked, 100-gram apple adds 14 grams of carbohydrates, three of which are in the form of fiber -- for a total of about 81 grams of carbohydrates and 9 grams of dietary fiber. While specific recommendations for carbohydrate intake may vary depending on age, activity level and health status, most adults are encouraged to get between 20 and 38 grams of fiber each day.
People who eat a large oat bran muffin can expect to get around 10 grams of protein, while 100 grams of an uncooked apple adds only trace amounts of this nutrient. According to the Centers for Disease Control and Prevention, healthy adults should aim for between 46 and 56 grams of protein each day. Those who are very physically active or who have infection or illness may require greater amounts of protein to meet physiologic demands.
Low in Fat
One large oat bran muffin provides around 10 grams of total fat, eight of which are unsaturated and two of which are saturated. One hundred grams of an uncooked apple provides only trace amounts of fat. Most adults are encouraged to limit total fat intake to no more than 25 to 35 percent of total daily caloric intake, or between 55 and 78 grams of fat for those following a 2000 calorie-per-day diet. Similarly, saturated fat intake should be no more than 7 percent of total daily caloric intake.
Vitamins and Minerals
Oat bran muffins can provide significant amounts of vitamins and minerals. In fact, people who eat a large oat bran muffin can get 58, 32 and 31 percent of the percent daily value for magnesium, iron and copper. A cooked apple that weighs 100 grams contains trace amounts of vitamin A, potassium and phosphorous.
