Prof. Seungho Baek's Medical Insight

Yogurt is milk that has been fermented, which makes it easier to digest but does not change what milk is. In ECM terms that means it suits four constitutions well, two conditionally, and two not at all.

Chicken suits the Water constitutions. But a Water type running hot cannot eat samgyetang without paying for it. Korean herbal pharmacy has an old answer to exactly this problem, and it works at the dinner table.

Constitutional food charts sort everything into beneficial and harmful, as though preparation were irrelevant. It is not. The same ingredient, cooked differently or eaten alongside something else, can stop being a problem.

Renotonia and Vesicotonia often conclude they drew a poor constitution — frequent minor illness, a fragile stomach, easy fatigue. That reading misses what they were actually given.

Eating when you are not hungry is not a failure of will. Korean medicine reads it as a specific imbalance — and there are four of them, of which two account for most of what happens in Renotonia and Vesicotonia.

Caffeine is the wrong instrument for Renotonia and Vesicotonia. But the more useful finding is that their concentration usually fails from the stomach, not the mind — and that even beneficial food, in excess, produces the anxiety that breaks it.

Pancreotonia and Gastrotonia tolerate caffeine well. But the thing that most often breaks their concentration is not fatigue — it is hurry, and caffeine makes hurry worse.

For Pulmotonia and Colonotonia, caffeine borrows alertness against tomorrow rather than generating it. What the Gold types actually run on is different — and so is what calms them.

Most constitutional advice about coffee is a warning. For the Wood types it is the opposite — and the reason is autonomic rather than a matter of taste.
