I often find myself heading to Subway after a long day at the clinic; even for a practitioner, the kiosk options can be quite overwhelming! From a Traditional Korean Medicine (TKM) perspective, Subway’s greatest strength lies in providing unprocessed fiber and the ability to customize ingredients to match your physical constitution. It is an ideal choice for those practicing glycemic control. However, one must be cautious of 'Spleen Deficiency' (Bi-heo). In TKM, raw vegetables are considered 'cold' in nature. Overconsuming them can deplete the body's digestive energy, leading to edema (swelling) or the accumulation of 'Phlegm-Rheum' (Dam-eum), which are metabolic waste fluids. This is especially true if you naturally have cold extremities or a sensitive stomach. To balance this, I recommend lean, warm proteins like Rotisserie Chicken or Roast Beef. Choose 'Wheat' bread for the fiber and ask to have the bread scooped out to slow carbohydrate absorption. Stick to simple dressings like olive oil, salt, and pepper to prevent water retention. If you feel bloated, pairing your meal with a warm soup is a great way to protect your 'stomach fire' and prevent 'Blood Stasis' (Eo-hyeol) by promoting healthy circulation through abdominal warmth. The most effective diet is one that respects your unique digestive capacity.
