Fiber, the Lost Nutrient

Posted on Posted in EatTagged , , , , , ,

Did you know that a whopping 97% of Americans aren’t getting the minimum recommended daily amount of fiber!? Fiber doesn’t exist in meat, eggs, or dairy, and is almost non-existent in processed, packaged foods. In order to get fiber, we have to eat plants – specifically vegetables, legumes, and whole grains. But why should we eat fiber?

A high-fiber diet is associated increased lifespan! In observational studies, fiber is associated with protection against heart disease, diabetes, metabolic syndrome, and cancer. Another benefit of consuming fiber – it tends to increase our intake of plant foods high in vitamins, minerals, and phytochemicals. It can regulate bowel movements, encourage a healthy gut microbiome,  lower cholesterol, help manage blood sugars, and reduce the risk of inflammatory bowel disease and colon cancer.  Our culture today is protein-obsessed, but high-protein diets have not been found to be associated with these positive health outcomes. We really should be fiber-obsessed! To learn more, listen to Dr. Michael Gregor’s short video on fiber and protein.

The recommended daily intakes of fiber for adult men and women (Institute of Medicine):

Men: 30-38 grams

Women: 21-25 grams

Making soups and stews with a variety legumes is of my favorite ways to get fiber. The below recipe is an easy to make, oil-free minestrone soup. If you are new to the fiber game, slow and steady wins the race. Eating a lot of fiber too quickly can cause bloating and gas, but don’t worry this WILL go away as your gut flora adjusts. Another tip for reducing bean-bloat is to buy your beans dry, soak them for 24 hours, and pressure cook before adding to soup. This also helps to remove lectins, which are substances present in many foods that may increase permeability of the gut lining. Soaking and pressure cooking can remove most of the lectins in beans.
