found really helpful was this one 5-to-1 rule for fiber in packaged foods basically you want to really increase your fiber to keep you feeling fuller longer and to be healthier. the 5 to 1 rule is you divide the total number of carbs by the total number of fiber grams. for instance if you have something that has 30 grams of carbs, and only 3 grams of fiber, that's 10, which is not good. if you have 30 grams of carbohydrates, with 6 grams of fiber, that's a 5 which is acceptable. under 5 is even better! basically the more fiber the better. it's always better to eat food
