Kombucha: verdict by goal
The details
Blood sugar: Fermented tea with a gut-health upside, but there's residual sugar (and some brands add more) — a small glass of a low-sugar brand is fine, a big sweet bottle isn't. Check the label for sugar per serving.
How to choose: Low-sugar (<5 g/serving), live cultures.
How to use it: Sip small; it's a probiotic, not a soda replacement by volume.
How to store: Fridge.
Sensible portion: ½ small bottle, few×/week
