How to Get More Fiber in Your Diet
Fiber.
That five-letter thing you know you should probably be eating more of but just not sure why or how. Most people think fiber is some cardboard-like prepackaged food that comes in a cereal or snack bar.
In reality, fiber is so important and comes in a wide variety of foods. Fiber passes through your stomach undigested, ends up in your colon, and promotes good gut bacteria. In addition to preventing constipation, fiber has been shown to promote weight loss and lower blood sugar levels.
I want to give you the rundown on everything you need to know about fiber: what it is, where it comes from, why you need it, and how you can get it into your daily diet!
What is Fiber?
Dietary fiber (the kind we eat – not the kind our clothes are made of) is a plant-based nutrient. The term “dietary fiber” refers to the indigestible parts of plant-based foods.
Fiber is a type of carbohydrate but, unlike other carbs, it cannot be broken down into digestible sugar molecules. Therefore, fiber passes through the intestinal tract relatively intact. However, on its journey, fiber does a lot of work.
Fiber is important to digestion and regularity, weight management, blood sugar regulation, cholesterol maintenance, and more. It has also been linked to longevity and decreasing the risk of cancer.
Two Types of Fiber: Soluble Fiber vs. Insoluble Fiber
Fiber can be put into two categories: soluble and insoluble fiber. Both are important for health, digestion, and preventing illness.
According to Medline Plus, soluble fiber attracts water and turns into gel during digestion and slows your digestion. It is found in oat bran, barley, nuts, seeds, beans, lentils, peas, and some fruits and vegetables.
Insoluble fiber adds bulk to your stool and helps food pass easier through the stomach and intestines. It is found in foods such as wheat bran, vegetables, and whole grains.
Why is Fiber so Important?
Fiber does so many amazing things before it makes its exit from the body.
1. Fiber controls your blood sugar levels and this is important because the more fiber you eat with each meal the slower it releases insulin (aka a fat-storing hormone).
2. Fiber helps with appetite control and keeps you fuller longer.
3. Fiber helps you stay regular (a.k.a. It helps you poop more) and flush out toxins.
4. You don't digest fiber (if you're familiar with the low carb diets, you can always subtract the fiber from the carbs to get NET CARBS for this reason) so your body works hard to move it along and this process actually revs up your metabolism.
5. You'll have more energy because your blood sugar levels are stable. So no crashing and trying to climb your way out of it by eating sugary filled foods only to do it all over again.
How to Get More Fiber in Your Diet
FIber is pretty great, isn't it?
Unfortunately, only 3% of Americans are actually getting enough fiber. Isn't that just crazy?
The Institute of Medicine has established a recommended daily amount (RDA) for fiber intake:
Men ages 50 and younger should consume 38 grams of fiber per day.
Men ages 51 and older should consume 30 grams of fiber per day.
Women ages 50 and younger should consume 25 grams per day.
Women ages 51 and older should consume 21 grams per day.
For us women, an easy way to get enough fiber each day is to break it down to about 8 grams of fiber per meal (a little less for women over 51).
