High Fiber Foods

Many diet plans tout the benefits of fiber. Although fiber forms part of a healthy diet, it is actually the indigestible part of a plant. Boosting your fiber intake is associated with numerous health benefits, making it important to ensure you get enough.

What Is Fiber?

Technically, dietary fiber is a type of carbohydrate. However, unlike the sugars and starches we usually envision when we think of carbohydrates, fiber is not digested by the human body. It is the portion of plants that contains cellulose and non-starch carbohydrates, which our bodies do not break down for energy. Dietary fiber is not a single type of molecule; rather, it is a class of molecules that share a similar chemical composition.

The Role of Fiber in the Human Body

Dietary fiber is also known as plant roughage. As fiber passes through the gastrointestinal tract, it undergoes certain changes despite not being metabolized (Brown et al., 1999). For example, fiber molecules may bind to bile acids or sugars while passing through the gastrointestinal system. Fiber also adds bulk to the stool and softens it, which normalizes bowel movements.

Soluble versus Insoluble Fiber

There are two primary forms of dietary fiber: soluble and insoluble (Mayo Clinic, 2015). Soluble fiber dissolves in water, creating a gel-like material. Fruits, vegetables, and oats are sources of soluble fiber. Soluble fiber is also associated with many of the health benefits of a high fiber diet, such as lowering cholesterol levels and stabilizing blood glucose.

By contrast, insoluble fiber cannot dissolve in water. This form of fiber adds bulk to the stool and pushes waste through the intestines to help the body eliminate waste. Whole-wheat products, beans, and certain vegetables are good sources of insoluble fiber. Getting enough insoluble fiber promotes gastrointestinal regularity. Both soluble and insoluble fiber are necessary parts of a healthy diet.

Choosing Foods High in Fiber

Most Americans do not get enough fiber each day (Vorvick, 2014). It is recommended that healthy men younger than age 50 consume 38 grams per day, while women under age 50 should consume 25 grams daily. After the age of 50, fiber needs decrease. Men older than 50 should aim for 30 grams per day, while women need 21 grams daily.

The best sources of fiber include whole grain products, fruits, vegetables, beans, nuts, and seeds (Mayo Clinic, 2015). Whole grain products may include brown rice, bulgur wheat, old fashioned oatmeal, whole-grain pasta, buckwheat, farro, or amaranth. Enriched versions of these grains strip them of the outer layer (the “bran”), which significantly decreases fiber content. Thus, opt for whole wheat or whole grain versions of the products whenever possible. When eating fruits and vegetables, leave the skins on before eating. Fruits and vegetables with the skins on are good sources of soluble and insoluble fiber.

Keep in mind that although fiber supplements are available, it is best to get natural fiber from the foods you eat. Natural fiber sources contain other vitamins, minerals, and nutrients that support health. Choosing high fiber snacks throughout the day is a good way to ensure you meet your daily target.

Health Benefits of a High Fiber Diet

Eating a high fiber diet has several health benefits. Consumption of soluble fiber is associated with lower cholesterol levels, better blood sugar regulation, and decreased risk of cardiovascular disease (Pereira, 2004). Additionally, fiber is good for the gastrointestinal system. Not only does getting plenty of dietary fiber improve gastrointestinal regularity, but it may also prevent diverticular disease in the colon (Mayo Clinic, 2015).

Fiber can also help you lose weight. Fiber-rich foods make you feel fuller for longer, decreasing cravings that interrupt your healthy food choices. One quick reminder, however, when increasing the fiber in your eating routine, it is important to drink plenty of water to prevent digestive distress.
