When I see people with continence issues, one of my first questions is about constitation and straining. There are many reasons that improving how easy it is to pass a stool will help continence.
This is where Fibre comes in .
Fibre isn’t just “one thing” — different types do different jobs in the body.
Most of us hear “eat more fiber,” but not all fiber works the same way in your body.
1. Two main types of fiber
Soluble fiber = heart & metabolic support
Found in foods like oat bran, nuts, barley, beans, peas, citrus fruits, chia and flax seeds, and in psyllium or methylcellulose supplements.
It forms a gel in the gut and helps improve blood sugar and cholesterol.
Insoluble fiber = digestive regularity
Found in wheat bran, whole grains, celery, kale, grapes, tomatoes, potatoes, and fruit skins.
It adds bulk to stool and helps prevent constipation.
2. Why fiber matters
Higher fiber intake is linked to lower risks of heart disease, stroke, high blood pressure, obesity, diabetes, and several cancers (including colorectal, gastric, and breast).
3. How much do we need?
Adults should aim for about 25–30 grams of fiber per day, from all sources.
4. Food first, supplements second
Whenever possible, get fiber from whole foods rather than supplements.
Example: one apple has about 4.4 g of fiber and includes both soluble and insoluble fiber.
Bottom line: Aim for a mix of high-fiber foods every day—fruits, vegetables, whole grains, beans, nuts, and seeds—to support both heart health and healthy digestion.
