Why can Subway sandwich sauce affect dieting from a Korean-medicine perspective?
Sugars and sodium in sauce can affect blood glucose, insulin, and fluid retention. Korean medicine also considers phlegm-fluid from weak digestion and blood stasis linked with salty flavor and stagnant circulation.
Simple sugars such as high-fructose syrup in commercial sauce can quickly raise glucose and affect insulin response and energy storage. This means checking the sauce’s sugar and amount separately, not assuming one sauce determines weight.
With weak digestion and absorption (bi-heo), nutrients may not be used as energy and may stagnate as phlegm-fluid. Also check whether a sweet, strongly seasoned sauce burdens your individual digestion.
A salty, high-sodium sauce can be considered alongside swelling and circulation stagnation, viewed as blood stasis. When choosing sauce, assess sugar, salt, and the whole sandwich, not only its vegetables.
