Q. Doctor, what do you think about the 'Subway diet' that is so popular among office workers? From the perspective of Traditional Korean Medicine, which menu items or combinations would you recommend?

Subway is a favorite for many on a diet because it allows for easy customization, such as hollowing out the bread to reduce carbohydrate intake while maximizing fiber and quality protein. However, from a Traditional Korean Medicine (TKM) perspective, one must be cautious of the 'cold nature' of raw vegetables. If someone with naturally weak digestion or a 'cold' abdomen insists on raw vegetables alone, they may damage their Spleen Qi, leading to a state of Spleen Deficiency (Pi-xu). This can result in chronic fatigue and abdominal discomfort. Sauce selection is also critical. Pungent or heavy sauces can lead to the accumulation of Phlegm-Fluid (Tan-yin), which are metabolic waste products that make the body feel heavy and hinder the reduction of edema (swelling). For the best digestive health, I recommend light dressings like olive oil or black pepper. Furthermore, I suggest pairing your sandwich with a cup of warm tea rather than a cold beverage. Keeping the internal abdomen warm ensures that metabolic functions remain active and that the nutrients from the vegetables are properly absorbed. It is also wise to omit high-sodium items like pickles or jalapeños. Choosing ingredients that your body can comfortably process, rather than just following popular trends, is the shortcut to a successful and healthy diet.
