Bowel Polyps - What You Should Know and How to Support Your Gut with Diet

Bowel polyps are small growths that form on the inner lining of the intestine, projecting into the bowel. They’re often symptom-free but may contribute to constipation. Most are discovered incidentally during a colonoscopy.

Although they can appear at any age, their frequency increases after age 30, and genetics often play a role. There are two main types:

• Adenomatous polyps (which have cancerous potential),

• Pseudopolyps, which result from inflammation and damage to the intestinal lining.

Detection and Risk

During a colonoscopy, polyps are usually removed with a simple endoscopic procedure. The tissue is then sent for histopathological analysis. Doctors assess its structure, location, and degree of dysplasia (abnormal cell development). High-grade dysplasia carries a higher risk of turning cancerous.

Diet and Gut Health: What Helps?

If polyps are diagnosed, nutrition should be tailored individually. Still, there are general guidelines that support intestinal health and may reduce risks:

Fiber

Fiber improves bowel movement and helps remove toxins and waste. It’s found in:

• Vegetables

• Fruits

• Whole grains (like oats and buckwheat)

• Legumes

• Wholemeal bread and cereals

Antioxidants

These protect cells from damage. Key sources include:

• Vitamin C: bell peppers, kiwi, parsley, strawberries, citrus fruits

• Vitamin E: nuts, seeds, cold-pressed oils

• Carotenoids: carrots, pumpkins, broccoli, and leafy greens

Omega-3 Fatty Acids

These have anti-inflammatory properties.

• EPA and DHA: oily fish (like salmon, mackerel), and algae

• ALA: flaxseeds, walnuts, almonds, and chia seeds

Supporting Gut Microbiota & Hydration

If there's no histamine intolerance, fermented foods can benefit gut flora:

• Sauerkraut, pickled cucumbers, beet kvass, kimchi

• Fermented dairy like kefir, natural yogurt, buttermilk

However, these are supportive - in more serious gut imbalances, targeted probiotic therapy is recommended.

Hydration Matters

Many people unknowingly struggle with dehydration. Adequate water intake helps regulate digestion, supports gut cleansing (via the migrating motor complex or MMC), improves mood, and may reduce snacking urges. Green tea is also a good choice - it's rich in polyphenols with anticancer properties.

What to Avoid

🚫 Processed red meat - classified as carcinogenic by the World Health Organisation

🚫 Fast food, hardened margarine, sweets - high in saturated fats, sugars, and additives

🚫 Excess calories - obesity are linked to increased cancer risk

Prevention Starts with Regular Checks

Diet plays a major role in prevention, but routine check-ups are just as important. Regular screenings can catch changes early, when treatment is most effective.
