You know that fiber is an important component of a healthy diet. But let’s be honest: Do you know what fiber is exactly? Let’s ask a dietitian.

“Fiber is the nondigestible part of plant foods that is found in whole fruit and vegetables, nuts, seeds, whole grains and legumes like greens, peas and lentils,” says registered dietitian Brynn McDowell. Dietary fiber is broken down into two main categories: soluble fiber, which dissolves in water and can be broken down by the good bacteria in our gut, and insoluble fiber, which does not dissolve and adds bulk to our stool, McDowell explains. Both are important to our daily diet, because fiber can help regulate blood sugar, lower cholesterol, feed the good bacteria in our gut, reduce the risk of heart disease, prevent constipation and help you feel (and stay) full after eating.

Current nutrition guidelines say that women under 50 years old should eat 25 grams of fiber per day, while women over the age of 50 should aim for 21 grams per day. And yes, getting enough fiber is important. “Low dietary fiber intake can lead to poor digestive health, meaning increased risk for constipation, diverticular disease and hemorrhoids,” McDowell says. “Cholesterol levels in the blood can also increase, which can lead to an increased risk for heart disease and stroke. A diet low in fiber typically means a diet low in fresh fruits and vegetables, whole grains, beans and legumes. In addition to being low in fiber, this can also mean a diet lacking in various nutrients, vitamins and minerals.” Yikes.

The great news is that adding high-fiber foods to your diet is pretty simple. One cup of raspberries contains eight grams of fiber, a cup of whole-wheat spaghetti has six grams and half a cup of black beans has 7.5 grams. Plus, adding fiber to your diet doesn’t have to be overly complicated. “I recommend looking at your current meals and seeing how you can add more fiber into what you are already eating,” McDowell tells us. “For example, choosing 100 percent whole-wheat bread over white bread will increase the fiber content. Adding some fresh berries and sliced almonds to yogurt, putting a scoop of chia seeds or flaxseed into your morning smoothie or adding beans to soups or chili are all simple steps you can take in the kitchen to add more fiber to your meals.” When increasing fiber in your diet, do it slowly and also make sure that you increase your water intake.
