Fiber is essential for good health and is especially helpful for weight management. Diets rich in fiber have been linked to many health benefits including bowel regularity, lower cholesterol levels, improved blood sugar control, and a healthier body weight.
Fiber is considered a carbohydrate and is found in plant foods such as vegetables, fruit, whole grains, beans and legumes, nuts, and seeds. Although humans lack the digestive enzymes needed to break down all the fiber we eat, some fiber provides fuel for intestinal bacteria that perform important functions in our body. This fermentable fiber is also referred to as prebiotics due to its important role of supporting healthy bacteria, also referred to as probiotics. Good sources include asparagus, artichokes, bananas, oatmeal, and legumes.
Fiber in whole foods is referred to as dietary fiber while fiber added to processed foods is called functional fiber. It’s best to get fiber from whole foods. Don’t be fooled by unhealthy snack foods that contain added fiber in an attempt to make the product appear healthier than it really is. Whole foods contain a combination of soluble and insoluble fiber. Soluble fiber attracts water and turns to a gel. This slows digestion and gastric emptying, which helps you feel full. Soluble fiber can also help lower blood sugar and cholesterol. Common sources include oatmeal, nuts, beans, lentils, apples, and blueberries. Insoluble fiber is beneficial due to its ability to add bulk and softness to stool, which helps decrease transit time and decreases the risk of constipation. Common sources include whole wheat, brown rice, legumes, carrots, cucumbers, and tomatoes.
