Fiber - It's Better For You Than You May Know

An apple a day keeps the doctor away. It is an age old adage. One most of us have probably heard with such frequency that we've never actually stopped to consider, "Why?"

Of course there is the obvious correlation: apples are fruits, fruits are healthy, therefore apples must be good for your health. But what if we looked a little closer? Why an apple? Why not a banana? A mango? Certainly oranges are higher in immune-supporting vitamin C. And yet, for hundreds of years, apples have been touted as the preeminent fruit to maintain your health. One possible explanation is that, in addition to its multiple other beneficial features, the apple happens to be one of the fruits that is highest in fiber.

Unfortunately, the importance of dietary fiber is often overlooked. Along with most essential nutrients, the average American diet fails to provide the recommended daily amount of fiber through food intake alone. However, getting the recommended 25 to 38 grams of fiber each day is one of the most effective ways to maintain a healthy digestive system. Surprisingly, good digestive health carries more benefits than simply maintaining regularity and avoiding the discomfort of occasional constipation.

Fiber aids the digestive process in multiple ways. In fact, there are two types of fiber—both of which play an equally important role. Soluble fiber (found in fruits, vegetables, oats, and legumes) absorbs water in the intestines and turns into a gel-like substance which slows the rate of glucose (sugar) absorption and helps maintain balanced blood-sugar levels. Insoluble fiber (found in whole grains) provides bulk and stimulates the intestinal muscles allowing food to pass through the digestive system more rapidly and with greater ease.

These processes are important for a variety of reasons. Maintaining bowel regularity decreases the contact time between stools and the intestinal wall, allowing less opportunity for the body to absorb harmful toxins. Fiber contributes to a healthier intestinal and colonic atmosphere by encouraging the growth of beneficial bacteria which, in turn, creates short-chain fatty acids that are rich in vitamin E and other nutrients.

On the whole, the benefits of fiber and its contributions to a person’s overall health and well-being are undeniable. And while an apple a day may, in fact, keep the doctor away, perhaps it is time for a new saying: Enjoy your fiber — because your body certainly does.

Signs You May Need More Fiber
1) You're Irregular
Since fiber adds bulk to your stool and increases food transit time through your digestive track, a high-fiber diet will help support regularity.

2) You Don't Eat 7-9 Fruits, Vegetables or Whole Grains a Day
If you currently don't consume many fruits, vegetables, or whole grains you're likely not getting enough fiber in your diet. These foods provide the majority of dietary fiber for most people.
