Prebiotic foods contain sources of nutrition for our gut bacteria. Our gut bacteria thrive when they are well fed – if you eat processed foods, then the majority of the bacteria that survive will be the type of bacteria that thrive off these foods, and they will send messages to your brain that make you crave more processed foods. That may explain why it can be so hard at first to give up a certain type of treat, but once we’ve gone a while without it we stop craving it. The best way to promote bacteria that give us a feeling of happiness is to nourish them with the right foods. To keep it easy, I’ve put together a list of prebiotic foods that can get us started.

Examples of prebiotic foods:

·         Almonds

Aloe Vera

·         Apples

·         Asparagus

·         Aubergine (Eggplant)

·         Bananas (closer to the green end of the scale than brown)

·         Brazil nuts

·         Broccoli

·         Brussels sprouts

·         Brown rice


·         Cabbage

·         Cauliflower

·         Cashews

·        Cocoa

·         Collard greens

·         Dandelion root

·         Dark chocolate

·         Eggplant (Aubergine)

·         Kale

·         Leeks


·         Onions

·         Potatoes

·         Radish

·         Walnuts

·         Wholegrain products – ie brown rice, brown pasta, wholegrain crackers
