Prebiotics and probiotics: which is which?
Prebiotics are plant fibers our bodies can’t digest but they serve as food for our gut bacteria. Lentils, whole grains, several vegetables, nuts all have several examples of these fibers, particularly those with complex carbs. Probiotics are living organisms that increase the population of good gut bacteria. Fermented foods like yoghurt, buttermilk, kimchi, miso, tempeh, sourdough, idli, dosas are all good examples. But remember to feed them with fiber too!

Which fibers are in which foods?
Soluble fibers are widely available in beans, oats, citrus, apples, psyllium, nuts – they absorb water and turn into a gel that protects the gastrointestinal muscles, while improving cholesterol and blood sugar levels. Insoluble fibers are found in whole grains, legumes, carrots, cucumber, tomatoes and the peels and skin of fruits and vegetables – these promote healthy bowel movements and help with insulin sensitivity. Before you get hung up on the classification, know also that most fiber-containing foods contain portions of both soluble and insoluble fibers. It’s more important to be consume sufficient amounts of fiber each day than worrying which type it is.
