Correct A Common Fiber Flub

"Even if a food claims to be high in fiber, it may not
deliver the benefits you expect. The problem? The processed
fiber that's added to many packaged foods is finely ground.
Compared with the fiber of whole foods, it doesn't slow digestion,
lower cholesterol, or improve regularity, says the Center for
Science in the Public Interest. Best bet: Stick to natural fiber
sources like avocado, beans, bran-based GF cereals, leafy greens,
GF oats, raspberries, and whole grain GF breads to get your 25 g
a day."
