You may have been hearing a lot of these two words when it comes to digestive health: pre- and probiotics.

But what exactly do they do for your digestion and do you need both of them?

Think of probiotics as your garden. It's the good bacteria in your stomach that you need to keep it growing in order to keep going.

Now what do we need for our garden? A little fertilizer to keep it healthy and that's what the prebiotics do.

The reason why you want your prebiotics to feed the probiotics is because probiotics, as we mentioned, grow the good bacteria in our gut. We need that to boost our immunity.

Eating probiotic foods also helps to manage irritable bowel syndrome, allergies and lactose intolerance.

Probiotics are your fermented foods like yogurt, sauerkraut, kimchi, miso, tempeh and kefir.

Good prebiotic foods include bananas, onions, garlic, leeks, asparagus, artichokes, soybeans and whole-wheat foods.
