What is all the fuss with fibre and why should I be eating 25g daily?
There are two main types of fiber:
Soluble fiber. This type of fiber dissolves in water. It forms a gel-like material in the stomach that slows down digestion.
Insoluble fiber. This type of fiber doesn't dissolve in water. It supports the movement of material through the digestive system and adds bulk to stool.
Main role of fibre in the body:
Promotes Digestive Regularity: Insoluble fiber acts as "roughage," adding bulk to stool and softening it, which helps move food through the digestive system faster, preventing or relieving constipation.
Feeds Good Gut Bacteria: Fiber, particularly fermentable fiber, serves as a prebiotic that feeds "good" bacteria in the colon, supporting a healthy gut microbiome and reducing inflammation.
Helps Manage Weight: High-fiber foods are more filling and take longer to chew, helping you feel satisfied longer and reducing calorie intake.
Lowers Cholesterol Levels: Soluble fiber dissolves in water to form a gel that can bind to cholesterol in the digestive tract, reducing the absorption of "bad" (LDL) cholesterol.
Stabilizes Blood Sugar: Soluble fiber slows down the digestion of food, which helps prevent sharp, fast rises in blood sugar levels after meals, reducing the risk of type 2 diabetes.
Reduces Disease Risk: Regular, high fiber intake is linked with a lower risk of heart disease, stroke, and certain types of cancer, particularly colorectal cancer.
Some high fibre foods to add to you diet:
Legumes & Beans (Highest Fiber Source)
Lentils: Approx. 15 grams per cup.
Black Beans: High in fiber, protein, and antioxidants.
Other Beans: Kidney, pinto, and cannellini beans are excellent, often containing pectin to support gut health.
Fruits
Raspberries & Blackberries: High in fiber and antioxidants.
Pears: Specifically with the skin on.
Avocado: Provides about 9 grams of fiber in a small fruit.
Other fruits: Apples, bananas, kiwi, figs, and dried fruits like apricots and prunes.
Whole Grains
Oats/Oatmeal: A great source of soluble fiber.
Whole-wheat Pasta & Bread: Ensure labels say "whole wheat" or "whole grain".
Quinoa & Brown Rice: Good alternatives to white rice.
Seeds & Nuts
Chia Seeds: Provides a massive fiber boost (10g/oz).
Ground Flax Seeds: Excellent for adding to smoothies or oatmeal.
Almonds & Walnuts: Good for snacking
Vegetables
Artichokes: One of the highest fiber vegetables.
Broccoli & Brussels Sprouts: Excellent cooked or raw in salads.
Sweet Potatoes: Contains both soluble and insoluble fiber.
When increasing fibre in the diet, always start slowly and ensure you are dinking plenty of water.
