What's the Difference between Fiber & Grains? Does It Matter?

I guess the difference is that grains contain fiber. whole grain breads, oatmeal, rice are all grains and some consider them "breads" in the old school. Most contain substantial amounts of fiber. But fruits and vegetables contain some fiber too. So it's not just in grains!

I guess they do include a lot of the same foods, but they're very different. Fiber is the material that comes from plants that your body can't digest. Some examples of fiber are: oatmeal, oat bran, beans, peas, rice bran, barley, citrus fruits, strawberries, apple pulp, whole-wheat breads, wheat cereals, wheat bran, rye, rice, barley, most other grains, cabbage, beets, carrots, Brussel sprouts, turnips, cauliflower, and apple skin. Any food made from wheat, rice, oats, corn, or another cereal is a grain product. Bread, pasta, oatmeal, and grits are all grain foods. Whole grains are just that, the whole thing. Refined grains have had some of the parts removed, and a lot of iron, vitamins, and fiber get removed in the process. Of course, to make it all even more complicated, there's carbohydrates. Again an overlap, but yet another definition. A few examples of carbohydrates are: bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. We need all of these (even carbohydrates - not all carbohydrates are BAD carbohydrates) - we're supposed to eat carbohydrates and grains that are also high in fiber. The more you can combine things, the better.
