| Calories | 440 |
| Carbohydrates | 98g |
| Proteins | 10g |
| Fats | 5g |
| Fiber | 9g |
| Calcium | 35mg |
| Iron | 1.2mg |
| Magnesium | 35mg |
| Potassium | 280mg |
From this table, we see that cornmeal contains 9 grams of fiber per cup. This is a significant amount, as the recommended daily intake for adults varies from 25 to 38 grams depending on age and sex. Thus, incorporating cornmeal into your diet can help you achieve your fiber goals for the day.
Is Cornmeal a Good Source of Fiber?
