I'm Dr. Bharat Pothuri, board-certified gastroenterologist with 25+ years treating digestive issues in Houston. Yes, Americans desperately need more fiber - I recommend 21-30 grams daily, but most patients I see get barely half that amount. The clearest sign you're fiber-deficient is inconsistent bowel movements - patients tell me they go days without regular elimination or strain constantly. Another red flag is when you feel sluggish after meals instead of energized, which happens because fiber helps stabilize how your body processes food. Our fiber crisis stems from convenience culture replacing real food with processed alternatives. When patients show me their typical grocery hauls, I see instant oatmeal packets instead of steel-cut oats, white pasta instead of quinoa. The food industry has trained us to choose products that last months on shelves rather than foods that actually nourish our gut microbiome. Here's my simple rule I give every patient: aim for 8-10 grams of fiber per meal by including one whole grain, one legume, and one fruit or vegetable. Black beans on brown rice with berries gets you there easily. Without adequate fiber, I regularly see patients developing diverticulitis, hemorrhoids, and chronic inflammation that could have been prevented with better food choices.
Hey, I'm Dr. Blen Tesfu, a medical advisor at Welzo. I advise on preventive health, nutrition, and evidence-based wellness. I'll answer your question: "What is fiber and why is it so important?" What is fiber and why is it so important? Fiber is a carbohydrate, of a sort, but it is not like other carbs — it is not a form of sugar — and your body cannot digest it. And that's a good thing. That's because, unlike the other nutrients, which are broken down and absorbed by the body in various ways, fiber stays whole as it moves through the digestive system — and it does some important work while it's there. There are two primary types: soluble fiber and insoluble fiber. Soluble fiber breaks down in water and can help lower cholesterol and regulate blood sugar levels. You can find it in foods such as oats, beans, and apples. Insoluble fiber doesn't dissolve — it just adds bulk to your stool and helps you stay regular. This variety is present in whole grains, carrots, and leafy greens. Think of fiber as your digestive system's clean-up crew, I often tell patients. It keeps things moving through your system, helps you feel full, and feeds the good bacteria in your gut, which can affect everything from your immune system to your mood. There's abundant evidence to suggest that getting enough can help lower the risk of heart disease, diabetes, and some cancers. It really is one of the most effective tools we have in everyday nutrition. I hope these insights are helpful for your article. Best Wishes, Dr. Blen Tesfu MD, and General Practitioner, Welzo
