Part 4 of 5
Today I'm killing bacteria on purpose. Heating kills every living bacteria in a spoonful of kraut, so by definition that's no longer probiotic. Scientists call what's left a paraprobiotic, or zombiebiotic. Dead cells, intact structure, and early research says even that can still trigger a gut response.

That sour tang in kraut isn't just flavour, it's proof of something the bacteria actually made. As they eat the cabbage, they produce short chain fatty acids, lactic acid and glutamic acid (+more) along the way, that's a postbiotic: a beneficial byproduct of fermentation. So this jar isn't just prebiotics and probiotics, it's got postbiotics too.

This jar is fizzing right now because there are billions of living things inside it. Probiotics are the actual living bacteria, not food for them, the bacteria themselves. But not all survive your stomach acid to reach your gut, which is why strain and dose matter more than "live cultures" on a label.

Part 1 of a 5-part series on prebiotics, probiotics, postbiotics, and zombie probiotics.

This garlic has zero bacteria worth talking about. So why eat it every day for gut health? Prebiotics aren't bacteria, they're food components your body can't digest (but your bacteria can). Not food for you, it's food for the bacteria already living in your gut. Onion, garlic, banana, oats, they all work the same way.

Pre, pro, post, and zombie, four words people sometimes confuse. Prebiotics are fibre that feeds your gut bacteria, probiotics are the living bacteria itself, postbiotics are what they produce while fermenting, and zombie biotics are heat-killed bacteria that can still trigger a gut response. One jar of kraut actually has three of the four in it at once.

Long ferments are dangerous, just not from mould. Mould can't grow without oxygen in an airtight jar. The real risk is pressure: CO2 builds up with nowhere to go, and the jar cracks or fizzes everywhere when opened. A small vented valve solves it.

Aboriginal Australians were fermenting Banksia flowers into a drink called Mangaitch as far back as 1836. We recreated it: soaked the cones, let it ferment, strained it, and tasted it live. Light, sweet, mildly alcoholic. Our ancestors knew what they were doing.

Raw cabbage contains raffinose and a goitrogen, two compounds that can cause bloating and affect thyroid function. Fermentation breaks both down and converts the cabbage's glucosinolates into sulforaphane, the same molecule broccoli sprouts are famous for. One hurts. One helps.

A common reason a ferment goes bad isn't bacteria, it's oxygen. Any veggie that pops up above the brine goes soft and mouldy. The fix: pack it tight and sit a weight on top. Most veggies release enough of their own juice, no water needed.

One reason people go carnivore: every vegetable contains toxins, a plant's self-defence mechanism. True, to a point. But fermentation significantly reduces those toxins, some by up to 95%. You don't need to cut out plants. You need to ferment them.
