Want better gut health without supplements? Dr Karan Rajan shares 7 everyday foods rich in natural prebiotics to boost digestion and overall well-being.

Want to support your gut and overall health without supplements? Many everyday foods contain natural compounds that nourish the beneficial bacteria in your digestive system, helping you feel your best. Dr Karan Rajan, NHS surgeon and health content creator, shared in his June 24 Instagram post how simple foods in your kitchen can boost your well-being through natural prebiotics.

Here’s what to add to your plate:

1. Bananas

“If you eat bananas, you get fructooligosaccharides, a prebiotic that improves calcium absorption in your colon, which can support bone health over time,” says Dr Karan.

2. Cooked and cooled potatoes

“If you eat cooked and cooled potatoes, you get more resistant starch, a prebiotic that improves insulin sensitivity and appetite regulation,” he adds.

3. Apples

“If you eat oats, you get prebiotic beta-glucan, which can trap cholesterol in your small intestine and, over time, help reduce LDL cholesterol,” says Dr Karan.

5. Chickpeas

Dr Karan explains, “If you eat chickpeas, you get a natural source of galactooligosaccharides, a prebiotic that can improve magnesium absorption and fuel the growth of lactobacilli.”

6. Garlic and onions

“If you eat garlic or onions, this double prebiotic fibre broadens the range of beneficial microbes that are fuelled,” he notes.

7. Sunflower seeds

“If you eat sunflower seeds, you get lignans and cellulose, which can help bulk up your stool,” Dr Karan recommends.
