Doctor's Recommendation Guide
Q. Subway is a popular choice for dieting these days. From a Traditional Korean Medicine perspective, which combinations or bread options would you recommend?
A.
Subway’s abundance of fresh vegetables is excellent for clearing 'Phlegm-retained fluid' (Dameum), but its cold nature can be burdensome for those with 'Spleen Deficiency' (Biheo) and weak digestion. I recommend choosing whole-wheat 'Wheat' bread and excluding pickled vegetables. The key is adjusting the ingredients to suit your unique body constitution.
📝 Detailed Answer
As a practitioner, I often grab Subway when I'm busy between treatments, and I've found it offers an interesting dietary synergy. The primary benefit is the high fiber content; in Traditional Korean Medicine (TKM), fresh vegetables are effective at clearing 'Phlegm-retained fluid' (Dameum), which refers to accumulated metabolic waste. However, a diet of cold raw vegetables can strain a 'Spleen Deficiency' (Biheo) constitution, as excessive coldness in the stomach can stagnate the 'Circulation of Qi and Blood.' Furthermore, high-sodium items like pickles or jalapeños can cause bloating and contribute to 'Blood Stasis' (Eohyeol). For a healthier choice, I recommend 'Wheat' bread and removing pickled items to reduce sodium. If you have a naturally cold constitution, pairing your sandwich with warm tea can help maintain digestive balance. Ultimately, the best diet is one tailored to your body's specific needs and digestive capacity rather than just following trends.
