I also occasionally grab a sandwich when I'm busy. However, there are times when I feel bloated afterward and realize that even as a TKM doctor, I overlooked my own body's needs. I will share the insights I've gained from my own trial and error. First, the advantages are clear. Sandwiches are rich in dietary fiber, providing great satiety and balanced nutrition. In particular, lean protein combinations like chicken breast or roast turkey help reduce systemic inflammation. However, there are points to consider. In TKM, weakened digestive function is referred to as 'Spleen Deficiency' (Bi-heo, 脾虛). If someone with a deficient Spleen consumes too many cold raw vegetables, their abdomen becomes chilled, often leading to diarrhea or indigestion. Similarly, when the body is in a state of 'phlegm-fluid accumulation' (Dam-eum, 痰飮), excessive raw vegetables can actually increase bloating. To simplify: if you typically have good digestion and a 'hot' body type, I recommend a fresh combination loaded with vegetables. Conversely, if you have cold hands and feet and slow digestion, it is better to moderate the amount of raw vegetables or supplement them with warm-natured sauces. Ultimately, the answer depends on your body's current condition. You must accurately understand your current digestive power and energy levels to maintain a sustainable diet. If you need a specific dietary guide tailored to your body, please feel free to visit the clinic. Let's figure it out together.
