For years, protein has reigned supreme in the health and wellness world. But experts are now arguing that fiber deserves a similar spotlight, and for good reason. While many Americans consume ample protein – roughly 20 percent more than recommended – the vast majority fall short of their daily fiber intake, a critical nutrient for overall health.
Most people don’t get enough fiber, a type of carbohydrate found in vegetables, fruits, whole grains, legumes, nuts, and seeds. National health recommendations suggest women and men under 50 aim for 25 and 38 grams of fiber daily, respectively. However, the average intake hovers around a mere 16 grams per day. This deficiency has significant implications for well-being.
“Fiber is essential for digestive health — it keeps the digestive tract moving smoothly and aids in bowel regularity,” explains Stacey Woodson, a registered dietitian nutritionist based in West Philadelphia. “It also helps keep blood sugar levels steady, maintaining balanced energy throughout the day. Furthermore, it may protect your heart by managing healthy cholesterol levels and promote weight management by increasing feelings of fullness after meals.”
To provide actionable advice on boosting fiber intake, we consulted four Philadelphia-based food experts – dietitians and a lifestyle medicine doctor – for their insights.
Simple Strategies to Increase Your Fiber Intake
Here are seven practical tips to incorporate more fiber into your diet:
-
Eat the Skin: Don’t peel your vegetables! Consuming the skin on cucumbers, potatoes, and zucchini can significantly increase your fiber intake. According to Charlie Seltzer, a Center City-based doctor specializing in obesity and internal medicine, up to 31 percent of a vegetable’s total fiber content resides in its skin.
-
Add Avocado: “Half an avocado provides three grams of fiber, along with healthy fats and antioxidants,” says Theresa Shank, a licensed registered dietitian and founder of Philly Dietitian. She suggests incorporating avocado into eggs, salads, or grain bowls for a balanced meal.
-
Embrace Beans and Legumes: A half-cup of beans delivers approximately one-fourth of the recommended daily fiber intake. Isabel Vasquez Larson, lead dietitian at Your Latina Nutrition, emphasizes the versatility of beans (black, kidney, pinto) and legumes (lentils, edamame, chickpeas) in dishes like tacos, salads, chili, pasta, and even pizza crusts. Beans and legumes also offer a substantial protein boost.
-
Choose Fiber-Rich Fruits: Fiber content varies greatly among fruits. Seltzer notes that blackberries, raspberries, guava, and kiwi are excellent sources, while watermelon, grapes, plums, and cantaloupe contain less. Prioritize fruits based on their fiber density.
-
Utilize Frozen Produce: Frozen fruits and vegetables are just as nutritious as fresh options and offer convenience. Vasquez Larson recommends adding frozen spinach to pasta sauces and frozen fruit to smoothies or yogurt bowls.
-
Understand Your Fibers: There are two main types of fiber: soluble and insoluble. Shank explains that soluble fiber dissolves in water, forming a gel-like substance that aids digestion, lowers cholesterol, stabilizes blood sugar, and supports heart health. Insoluble fiber, on the other hand, adds bulk to stool, promoting regularity and preventing constipation. To increase soluble fiber intake, Shank recommends stirring a spoonful of chia seeds into water with lemon. Leafy greens, almonds, walnuts, and apples with the skin on are excellent sources of insoluble fiber, according to Woodson.
-
Consider Supplements (With Caution): While a food-first approach is always best, supplements can be helpful for those struggling to meet their fiber needs. However, Vasquez Larson cautions that supplements aren’t one-size-fits-all. Consulting a doctor, nutritionist, or dietitian is crucial to determine if a fiber supplement is appropriate. Seltzer favors psyllium husk powder, containing four grams of fiber per teaspoon, despite its sometimes-unpleasant texture.
Ultimately, prioritizing fiber intake is a vital step towards optimal health. By incorporating these simple strategies into your daily routine, you can unlock the numerous benefits this often-overlooked nutrient provides.
