Welcome to the Gut-Loving Guide on fiber, dedicated to optimizing your gut health journey!

As a dietitian specializing in digestive wellness, I'm thrilled to have you here. Let's dive into the world of fiber – the indigestible component of plant-based foods that plays a pivotal role in nourishing your gut and overall well-being. From the fascinating types of fiber to its exceptional health benefits, we're about to uncover the secrets to a thriving gut.

There are two main types of fiber: soluble fiber and insoluble fiber, and most high-fiber foods contain a combination of both.

Balancing different types of fiber in your diet is key to reaching this goal, accompanied by sufficient fluid intake to maintain healthy digestion and prevent discomfort.


Insoluble fiber holds the keys to a well-functioning digestive system: • It aids in eliminating toxins from your body. • By adding bulk, it promotes regular bowel movements and prevents constipation.

• It acts as a safeguard against gut infections, hemorrhoids, heart disease, and specific types of cancer.


Soluble fiber, on the other hand, operates as a versatile ally within your gut: • It binds with cholesterol, effectively removing it from your bloodstream. • By reducing cholesterol absorption, it actively lowers cholesterol levels. Achieving these benefits requires a daily intake of approximately 10 to 12 grams of soluble fiber. • It regulates blood sugar levels by slowing down digestion, serving as a cornerstone for blood sugar management. • Soluble fiber’s ability to enhance stool consistency helps manage diarrhea. • With its knack for delaying stomach emptying, it curbs cravings and sustains satiety, assisting in appetite control.


When it comes to fiber, quantity matters. The American Dietetic Association recommends a daily intake of 20 to 35 grams, while Health Canada suggests individuals over 18 aim for 25 to 38 grams of total fiber. However, it's important to note that most people tend to consume only around 15 grams per day. EMBRACING FIBER IN YOUR DIET

Elevate your fiber intake with these insightful tips:

  • Start your day with nourishing oat or oat bran cereals.

  • Blend cereals containing psyllium, like All Bran Buds, for a fiber-packed breakfast.

  • Opt for fresh or dried fruit over candies and replace desserts with options like fruit cobbler or whole-wheat muffins.

  • Explore bean dips like hummus and refried beans with whole grain crackers or veggies.

  • Elevate your meals by incorporating wheat germ into hot cereals or yogurt.

  • Add oats, oat bran, ground flaxseed, chia, or cereals with psyllium to an array of dishes, from bread mixes to smoothies.

  • Transform salads and soups with the inclusion of cooked navy or black beans.

  • Unite the goodness of cooked lentils with lean ground beef in versatile recipes.

  • Savor satisfying snacks like roasted soy nuts, edamame, and unsalted peanuts, paired with fruits or vegetables.

  • Enrich your diet with barley in soups, casseroles, or as a wholesome rice substitute.

  • Upgrade your salads with unsalted peanuts, soybeans, avocado, berries, or oranges.

  • Fuse baked squash and carrots with mashed potatoes for a delightful twist.


Unlock the power of soluble fiber in these food sources:

  • Cooked barley, oatmeal, oat bran, and quinoa

  • Beans like black-eyed peas, chickpeas, and more

  • Healthy fats such as avocado, chia seeds, and ground flax seeds

  • Vegetables like broccoli, Brussels sprouts, carrots, and more

  • Starchy vegetables like sweet potatoes and green peas

  • Fruits including kiwi, apple, banana, guava, orange, peach, pear, and more


Imagine awakening to a bowl of oatmeal interwoven with berries and ground flax. Noon arrives with a chili adorned by beans, followed by a pear's sweet embrace. The sun-drenched snack pairs raw carrots with hummus. As evening whispers its secrets, a medley of steamed cabbage, broccoli, and green beans graces your table.


Discover the benefits of soluble fiber supplements, a catalyst for gut health:

  • Soluble fiber supplements aid in improving gut function by enhancing stool size and consistency.

  • Selecting a prebiotic supplement can modify the gut microbiome and foster positive bacterial growth.

  • These supplements assist in lowering LDL cholesterol by binding to bile acids in the large bowel.

  • Balancing fiber intake with IBS can be challenging; soluble fiber supplements offer symptom relief.


Enhancing Digestive Health Through Soluble Fiber Supplements

Soluble fiber supplements offer valuable support for optimal gut function. They work by enhancing the size and consistency of stools, thereby improving the transit time of food through the digestive system. If your chosen fiber is a prebiotic, it can also positively influence the composition of your gut microbiome, fostering the growth of beneficial bacteria.

Lowering LDL Cholesterol and More

These supplements also play a role in lowering LDL cholesterol levels. By binding to bile acids in the large intestine, they prevent the reabsorption of these acids into the bloodstream, which helps in reducing cholesterol reabsorption. Whether you're seeking to increase your overall fiber intake or target specific digestive issues, soluble fiber supplements can be beneficial.

Addressing Fiber Intake Challenges

Meeting the recommended daily fiber target of 30g can be particularly challenging, especially for individuals with irritable bowel syndrome (IBS). High-fiber foods might trigger IBS symptoms, making it necessary to explore alternative sources like soluble fiber supplements. There are many soluble fiber supplements which are suitable, and they can help relieve symptoms, including constipation and diarrhoea.

Tailoring Choices to Your Needs Selecting the right soluble fiber supplement hinges on your individual requirements and preferences. Key factors to consider include a high soluble fiber content, low caloric value, and practical aspects such as viscosity. By taking these factors into account, you can make an educated decision.


Psyllium Husk: A Premier Soluble Fiber Supplement Derived from the seed husks of the Plantago ovata plant, psyllium husk stands out as an exceptional soluble fiber supplement. Its rich soluble fiber content allows it to absorb and retain substantial amounts of water, softening stools and influencing gut motility. This helps regulate the pace of digestion, promoting either slower or faster motility as needed. Psyllium husk effectively manages both constipation and diarrhea, including general IBS symptoms. Importantly, it remains non-fermentable, making it well-tolerated by those with IBS.

Optimal Usage of Psyllium Husk Research suggests an effective regimen of around 10g of psyllium husk daily over at least four weeks for constipation management. Your individual needs may vary. Start with approximately one tablespoon daily in the first week and gradually increase to 3 tablespoons per day over three weeks. While psyllium husk is available in both powder and capsule forms, the powder form is recommended due to its higher content. Capsules usually only contain 0.5g each so you would need to take a lot to reach your target. Additionally, products like Fybogel and Metamucil contain psyllium husk and are worthwhile options.

Partially Hydrolyzed Guar Gum (PHGG) Sunfiber's active ingredient, PHGG, is derived from guar beans. The hydrolyzed guar gum breaks down into smaller units, reducing viscosity and enhancing solubility. This results in a more easily tolerable texture when consumed. PHGG demonstrates positive outcomes in alleviating symptoms, enhancing stool consistency and frequency, and reducing reliance on laxatives for constipation-predominant IBS. Moreover, PHGG acts as a prebiotic, supporting increased levels of Bifidobacteria, which tend to be deficient in individuals with IBS.

Acacia Fiber: A Gentle Prebiotic Also known as 'gum Arabic', acacia fiber is sourced from the sap of the Acacia Senegal tree. This low-viscosity soluble fiber serves as a prebiotic and has shown promise in improving bowel habits and IBS symptoms when included in a daily yogurt containing Bifidobacterium lactis. Available in powder form, it can be effortlessly blended into beverages or used as a food ingredient. Azacen acacia gum powder sachets are certified low FODMAP.

Linseeds (Flaxseeds): An Effective Choice Linseeds, or flaxseeds, offer another valuable soluble fiber supplement. Research supports their efficacy in relieving constipation, abdominal discomfort, and bloating associated with IBS-C. Available in ground or whole forms, you can gradually increase consumption from half a tablespoon per day to 1.5 tablespoons per day over three weeks if symptoms persist. Sprinkle them onto yogurts, cereals, soups, salads, and more. Note that quantities above 1.5 tablespoons might elevate FODMAP levels.

Chia Seeds: Nutrient-Rich Soluble Fiber Chia seeds provide approximately 5g of soluble fiber per tablespoon, with low FODMAP content at two tablespoons. Ideal for adding to porridge, yogurts, smoothies, and even chia pudding, they offer a versatile nutrient boost. You can try a daily, delicious chia pudding. You can find the recipe in our Gut-Loving Cookbook.

However, they might not be suitable for individuals struggling with constipation due to their high viscosity, which can exacerbate the issue. If after trying it for a week your constipation doesn’t resolve, we encourage you to try the other options.

Inulin: A Prebiotic Fiber with Considerations Inulin, a soluble prebiotic fiber found in various vegetables such as asparagus, garlic and leeks, is also available in supplement form, often extracted from chicory. Research indicates its potential in improving stool frequency and consistency. ·However, due to its high FODMAP content and potential to trigger bloating, flatulence, and abdominal discomfort, caution is advised, making it unsuitable for individuals with IBS.


  • Introduce fiber to your diet gradually, spacing high-fiber foods throughout the day.

  • Begin with a small amount mixed with water and progressively increase your intake.

  • This approach minimizes potential gas and discomfort associated with rapid fiber increase.

  • Adequate hydration is key; aim to drink extra water as fiber intake rises (9 to 12 cups/day).

  • Patience is essential; soluble fiber supplements take time to show effects, typically 2-3 days.

  • Allow at least four weeks to experience the full positive impact of a supplement. Soluble fiber supplements present a range of options for promoting digestive health. By considering your specific needs, preferences, and potential sensitivities, you can make informed decisions to support your well-being.
