# Plant-Based Fiber: The Key to Good Health **By Dr. Neal Barnard** · 2024-11-27 ![A variety of fiber-rich foods including fruits, vegetables, whole grains, legumes, and seeds, such as avocados, bananas, oranges, broccoli, whole-grain bread, and chia seeds.](https://cdn.shopify.com/s/files/1/0319/0960/9603/files/Plant-Based_Fiber_The_Key_to_Good_Health_375_x_250_px.png?v=1732731526&width=300&height=200&crop=center) Fiber plays a key role for digestion, and is associated with weight loss, cancer prevention, and longevity. However, not all fiber is created equal. Packaged food companies are trying to boost sales by adding extra fiber to their gummy candy or yogurt, but the best source of fiber comes directly from plants. Yes, natural fiber is found in fruits, vegetables, whole grains, and legumes. For optimal health, make sure your plate is packed with whole plant foods high in dietary fiber. ## What is Fiber? Fiber is a type of carbohydrate that our bodies cannot digest, and it comes in two forms: soluble fiber and insoluble fiber. ### 1\. Soluble Fiber ### Is miralax a soluble fiber? - **Found in:** Oats, beans, legumes, and some fruits and vegetables. - **Benefits:** Lowers cholesterol levels and supports heart health. One easy way to fold in more soluble fiber is [**apple pectin**](/products/apple-pectin-700mg "/products/apple-pectin-700mg"), the same gel-forming fiber found in the fruit itself. [**Inulin, a plant fiber from chicory root**](/products/inulin-pure-powder "/products/inulin-pure-powder"), is another gentle option that feeds your gut bacteria. Both are simple plant based fibers to add to a plate already built around whole plant foods. ### 2\. Insoluble Fiber - **Found in:** Whole grains, fruits, vegetables, kidney beans, and bran. - **Benefits:** Acts like a broom, cleaning the digestive tract and promoting regularity. Both of these fibers are plant-based, and meat and dairy do not contain any natural fiber, yes, even your fiber-fortified yogurt. Processed foods with added nutrients rarely offer the full benefit of real food. 👉 Pro Tip: Skip processed options and choose food that's high in fiber like raspberries (8 grams of fiber per cup) or red lentils (16 grams of fiber per cup). And lentils, which have 18 grams of protein per cup, can be added to anything. ## Plant-Based Fiber and Weight Loss If you’re looking to lose weight, a fiber-rich diet is one of the simplest and most effective solutions. My colleagues and I published a [**study**](https://pubmed.ncbi.nlm.nih.gov/25620754/ "https://pubmed.ncbi.nlm.nih.gov/25620754/") in the _Journal of the Academy of Nutrition and Dietetics_ showing that simply switching to a plant-based diet leads to significant weight loss, without any calorie counting or exercise. Fiber helps you feel fuller for longer, reducing overeating and promoting sustainable weight management. ## Cancer Prevention with Plant-Based Fiber Fiber also helps reduce cancer risk, in addition to aiding weight loss and improving your digestive system. Here’s how: - **Improved digestion:** Fiber improves the intestinal transit of food and waste, helping the body eliminate carcinogens. - **Reduced colon polyps:** [**The U.S. Polyp Prevention Trial**](https://dceg.cancer.gov/research/what-we-study/polyp-prevention-trial#:~:text=The%20primary%20objective%20of%20the,polyps%20of%20the%20large%20bowel. "https://dceg.cancer.gov/research/what-we-study/polyp-prevention-trial#:~:text=The%20primary%20objective%20of%20the,polyps%20of%20the%20large%20bowel.") found that a high-fiber diet reduce the occurrence of colon polyps. - **Lower cancer risk:** A [**meta-analysis**](https://pmc.ncbi.nlm.nih.gov/articles/PMC4161278/ "https://pmc.ncbi.nlm.nih.gov/articles/PMC4161278/") published in the _Journal of the National Cancer Institute_ examined 13 studies and found a direct link between high fiber intake and decreased risk of colorectal cancer. Increasing your fiber intake by eating plant foods is not only a great way to shield your body against cancer, but it’s also a smart way to improve your overall health. ## How to Get Enough Fiber Each Day Most Americans consume only 10-15 grams of fiber daily, while health authorities recommend 25-38 grams depending on age and sex.
