AIIMS-certified doctor says these 7 foods can protect against colon cancer: 3 anti-inflammatory recipes

Colon cancer still feels like a distant worry for many people, but gastroenterologists repeatedly say the same thing, the everyday food on your plate can quietly shape your gut’s future. A Harvard-trained gastroenterologist, Dr Saurabh Sethi (doctor.sethi), MD, MPH, Gastroenterologist, Harvard, Stanford, AIIMS, known for helping people take charge of their gut health, recently highlighted seven ingredients that consistently show protective benefits. These foods aren’t exotic superfoods flown from somewhere far away; they’re the simple, old-school staples your grandmother trusted, lentils, greens, garlic, onions, oats, berries, and broccoli. Together, they build a gut environment that cools inflammation, strengthens the colon wall and supports a healthier microbiome. Here’s a deeper look at what makes each food powerful, followed by three anti-inflammatory recipes that turn them into everyday meals...

Broccoli, cauliflower, cabbage, mustard greens, they all contain sulforaphane, a compound known for defending cells against chronic inflammation. Your liver also loves cruciferous vegetables because they support detoxification pathways, indirectly benefiting your gut.

Blueberries, strawberries, mulberries, and jamun each one carries a mix of polyphenols and flavonoids that are linked to a reduced risk of colon inflammation. They also act as prebiotics, feeding your gut bacteria while delivering natural sweetness without spiking blood sugar the way desserts do.

Protein-packed, fibre-heavy and extremely forgiving on the wallet - beans and dals help the colon do exactly what it loves: move. Their soluble fibre forms a gel-like texture that feeds good bacteria, while insoluble fibre keeps things flowing. Regular intake has been linked to lower inflammation markers and improved stool bulk - which reduces pressure on the colon walls. Think rajma, chole, moong, masoor, urad, all quiet heroes.

When it comes to colon-loving grains, whole grains win. Oats and barley are rich in beta-glucans, thick, soothing fibres that calm inflammation. Quinoa adds complete protein, making meals feel more balanced. Together, they help stabilise blood sugar, support regularity and keep the gut lining strong.

Spinach, methi, amaranth, sarson - leafy greens bring chlorophyll, antioxidants and a gentle boost of fibre. They hydrate the colon, reduce oxidative stress and keep bowel movements soft. Greens also supply folate, a B-vitamin linked to healthy cell division in the colon.

Garlic is one of nature’s most underrated anti-inflammatory foods. Its compound allicin has antimicrobial, immune-supporting and gut-balancing effects. Regular intake has been associated with lower inflammation - and a reduced risk of colon issues. Lightly crushed raw garlic mixed into warm dal or cooked sabzis can make a noticeable difference.

Like garlic, onions are rich in prebiotic fibres, especially inulin. They feed beneficial bacteria, reduce inflammation and support smoother digestion. Red onions carry extra flavonoids, making them even more gut-friendly.

Warm moong dal khichdi with garlic ghee - To make it, take soaked moong dal, rice (or replace rice with barley), turmeric, and a pinch of black pepper and simmer until soft. Finish with a spoon of ghee tempered with crushed garlic. This bowl is gentle on the stomach, rich in fibre and packed with plant protein, perfect for days when digestion feels off.

Berry and quinoa breakfast bowl - To make it, cook quinoa in water or milk, stir in a handful of berries, and add chopped nuts, seeds and a drizzle of honey. This combination offers complete protein, antioxidants, fibre and natural sweetness without any heaviness. It’s also a powerful anti-inflammatory start to the day.

Broccoli oat tikki - To make it, take steamed broccoli, rolled oats, grated onion, chilli, coriander and a squeeze of lime. Mash, shape into tikkis and pan-sear. These patties deliver sulforaphane from broccoli and beta-glucans from oats, a double win for colon health. They work as snacks, side dishes or even burger patties.
