6 Ways to Help Fiber Work Better
Getting enough fiber is really quite simple. If you follow the recommendations of the “Food Guide Wheel” and include the amounts of healthy grains, fruits, vegetables, and legumes it suggests, you will automatically get enough fiber in your diet. Here are some additional tips to help fiber work better in your body.
1. Increase the amount of fiber in your diet gradually
Your intestines will be more comfortable with this approach than with a sudden onslaught of high-fiber foods. Too much fiber too soon is likely to catch your intestines off guard, leading to bloating and gas. Each week, increase the amount of fiber in your diet by about 5 grams a day for adults and 1 to 2 grams a day for children until you reach your individual intestines-friendly daily amount. This is usually somewhere between 25 and 35 grams a day for adults, and half that for children. Keep experimenting with the amount and type of fiber that gives you a comfortable “gut feeling” to help fiber work better in your body.
2. It’s important to eat fiber from a variety of sources
By eating many types of high fiber foods, you are more likely to balance out the right amount of soluble and insoluble fibers. The more soluble the fiber, the more it ferments, and therefore the more gas it produces.
3. Spread out your dietary fiber throughout the day
Overdosing on fiber at any one meal is liable to produce bloating and gas.
4. Drink a lot of water with your fiber
To help fiber work better in your body, there has to be an adequate amount of water for it to absorb. Otherwise, fiber may actually contribute to constipation rather than prevent it. Or it may soak up water and other nutrients needed elsewhere by the body.
5. Get your fiber from food, not from pills
The fiber in a pill may not work the same way, biologically, as fiber that comes from actual food. To help fiber work better and do it’s job, it needs to be eaten in the company of other foods and with a lot of fluids.
6. Avoid fiber-induced nutritional deficiencies
Overdosing on fiber can interfere with the absorption of valuable nutrients. Fiber can push food through the intestines so fast that some nutrients, such as calcium, zinc, vitamins, and iron don’t have a chance to be fully absorbed. You could avoid eating high-fiber foods at the same time you eat foods containing these nutrients, but this is impractical. If you’re on a diet that includes more than 35 grams of fiber a day, you should consider taking vitamin and mineral supplements.
