DIET · 5 MIN READ
Here's the part of TCM food theory that surprises people: a food's "thermal nature" (四气: cold, cool, warm, hot) has nothing to do with its serving temperature. Mung bean soup can arrive at the table steaming and still count as cooling. What matters is how the food behaves in the body afterward. If you deal with congestion and clear, watery mucus, the distinction is worth learning, because the usual advice is to lean toward warming foods whether they're served hot or cold.
The claim, in plain terms: too many iced drinks, raw vegetables, and cold desserts burden the spleen (脾) and congeal fluids, and the body answers with more of that thin, watery mucus. Nobody is talking about bacteria here. It's about how your body handles temperature load.
Note: these are everyday foods, not treatments. Enjoy them as part of a balanced diet.
You don't need to live on hot food. Tilt the average toward warmth, especially in cool seasons, and you've done the job. An iced drink now and then is a pleasure, not a problem. A daily iced-drink habit is what TCM would question.
Pair this with the daily routine and the autumn guide for a fuller picture.
