5 High-Fiber Foods That Naturally Support Digestion & Relieve Constipation

These aren’t “miracle” laxatives — they’re whole foods that promote long-term digestive health.

1. Prunes (Dried Plums) – Nature’s Gold Standard
One of the most studied natural remedies for constipation
Packed with:
Soluble and insoluble fiber (7g per ½ cup)
Sorbitol — a sugar alcohol that draws water into the intestines
Phenolic compounds that stimulate gut motility
📌 Studies show prunes improve stool frequency and consistency better than fiber supplements alone.

✅ Try: 3–5 prunes daily with plenty of water.

2. Kiwi Fruit – Small but Mighty
Two medium kiwis = ~4.5g fiber
Contains actinidin, an enzyme that supports digestion
Rich in water and antioxidants
🔬 Clinical trials found eating two kiwis daily improved bowel movements in people with chronic constipation.

🥄 Pro Tip: Eat with the skin (after scrubbing) — it triples the fiber!

3. Chia Seeds – The Hydration Boosters
Absorb up to 10x their weight in water → form a gel that softens stool
High in soluble fiber (10g per ounce)
Also rich in omega-3s and protein
💧 How to use: Soak 1 tbsp chia seeds in 1 cup water or plant milk for 15+ minutes before consuming.

🚫 Never eat dry chia seeds — they can clump and cause choking or blockages.

4. Leafy Greens (Spinach, Kale, Swiss Chard)
Packed with fiber, magnesium, and water
Magnesium helps relax intestinal muscles and draw fluid into the colon
Low-calorie, high-volume — ideal for gut health
🥗 Add raw or lightly cooked greens to smoothies, soups, or salads.

💡 Bonus: Chlorophyll may support detoxification pathways (though not a “cleanse”).

5. Apples & Pears – With Skin On
One medium apple (with skin) = ~4.4g fiber
Contain pectin, a type of soluble fiber that ferments in the colon and speeds transit time
High water content (~85%) adds hydration
🍎 Eat whole — juicing removes most fiber.

❗ For some with IBS, apples/pears may worsen bloating due to fructose/FODMAPs — adjust based on tolerance.
