Quick Answer: Are whole grains a good source of fiber? Whole-grain foods in general are a good source of fiber.

However, it can differ from food to food. In this part, we will take a look at several whole-grain foods and see how good of a fiber source they are.

Let’s start with whole grain oat flour. One cup of whole-grain oat flour has 12.1 grams of fiber and 455.3 calories. This means that for every 100 calories you eat you would get 2.7 grams of fiber.

One slice of whole-grain wheat bread has 3.3 grams of fiber and 85.7 calories. Every 100 calories of whole-grain wheat bread are worth 3.9 grams of fiber. This makes it even better than foods made with whole-grain oat flour.

A cup of whole-grain cornmeal has 8.9 grams of fiber and 441.6 calories. You will get 2 grams of fiber for every 100 calories of whole-grain cornmeal.

Based on this we can see that whole grains, in general, are a decent source of fiber. Obviously, they don’t come close to some of the titans of the fiber world, such as fruits and vegetables, but they can play a role in your diet.

In general, you want your fiber-rich diet to contain as many different foods as possible. This means that some foods that contain more fiber will be your main fiber sources. Others will play a supporting role and help you get those last bits of fiber needed to reach your daily goal.

What should your daily fiber goal be? According to nutritionists, it is 30 grams. You can eat a few slices of whole-grain wheat bread and get closer to that amount, but don’t count on whole-grain foods to be your only fiber source.

Try to combine multiple different foods rich in fiber and your diet will truly start to shine. Whole grains earn a spot in that diet for sure, but not the biggest one!

Now, let’s compare whole grains as a fiber source to some similar foods.

Comparing Fiber In Whole Grains To Similar Foods

We’ve given you several examples of whole grains and talked about their fiber content. Whole grain wheat bread was the best with 3.9 grams of fiber per 100 calories. Now, let’s compare it to other similar foods based on their fiber content:

  • One tablespoon of flax seeds has 2.9 grams of fiber and 56.1 calories (5.2 grams of fiber per 100 calories) Flax seeds are generally a better source of fiber than whole grains.
  • Graham Crackers have 2.9 grams of fiber and 370.8 calories per cup. (0.8 grams of fiber per 100 calories) Graham Crackers are not a good source of fiber at all, and most whole-grain foods are better.
  • A cup of Honey Nut Cheerios has 2.7 grams of fiber and 140 calories. (1.9 grams of fiber per 100 calories) They are not the worst source of fiber, but whole grains are mostly a better pick.
  • Hemp seeds have 6.4 grams of fiber and 884.8 calories per cup. (0.7 grams of fiber per 100 calories) Hempy seeds are not a good fiber source, so whole grains win this one as well.
  • A Nutri Grain Bar has 1.2 grams of fiber and 134.4 calories. (0.9 grams of fiber per 100 calories) This is yet another subpar fiber source, meaning whole-grain foods get another victory.
  • A tablespoon of chia seeds contains 3.4 grams of fiber and 48.6 calories (7 grams of fiber per 100 calories) Chia seeds are a great source of fiber, and whole grains, in general, can’t compare.

How Much Fiber Whole Grains Contain By Quantity

However, the amount of fiber they provide is not good enough to make them one of your main fiber sources.

While you get the majority of your fiber from other foods, whole grains can be there to make up for what’s left until you reach your fiber goal.
