O to be regular!!
On my box of Kellogg's All-Bran cereal, they challenge you to eat a bowl of the cereal every morning and see if you notice a difference after two weeks. Kellogg's All-Bran has 10 grams of fiber in half a cup. Well, I've been eating a bowl of Kellogg's All-Bran Bran Buds each morning and that cereal has 13 grams of fiber in one third of a cup (another wonderful thing about fiber is the more fiber there is in a food, the less calories). I'm getting almost half my daily fiber needs in just 70 calories!
I recommend all-bran cereal to everyone. With a bowl every day, it's easy to meet the 30 grams of fiber per day you need, plus it has so few calories you can have it with whatever else you like to have for breakfast (or mix it with whatever you'd like to give it better flavor). And the two-week difference is real: I'm regular for the first time in decades! O, fiber! I love fiber!
