TIL that sauerkraut actually loses most of its probiotics if you heat it above 115°F

Honestly, I was reading a fermentation science blog from University of Wisconsin last night and found out that pasteurizing homemade kraut above 115°F kills off the good bacteria. I've been tossing my jars of fermented cabbage into hot soups and stir-fries for months thinking I was getting all the gut benefits. Did I just waste 6 batches of kraut, or am I overthinking this?

Yeah, "waste 6 batches" is harsh but I get the frustration. It's the same pattern I see everywhere - we get sold on one tiny benefit and forget the whole picture. Like avocado toast people who refuse to eat bread but load up on an entire avocado. Or people who buy expensive organic kale but microwave it to death. Fermentation is messy and full of tradeoffs. The heat kills the live bacteria but the dead bacteria still feed your gut microbiome. Plus the taste and texture are still there. So no, you didn't waste anything. Just eat it raw when you want the probiotics and cooked when you want the flavor.

Is it really that serious though? We're talking about bacteria in cabbage here. Either you enjoy fermented stuff or you don't. The health hype around probiotics is just the latest wellness fad that'll fade when the next thing comes along. Reminds me of the cold brew craze or when everyone swore by bone broth. Eat your sauerkraut how you like it and move on.
