In my own experience during busy days, I've sometimes relied on soy milk for quick meals, only to find it occasionally causing bloating. From both a clinical and personal perspective, soy milk can be a double-edged sword. The advantages are clear: as a plant-based protein, it provides prolonged satiety and requires zero preparation time, making it an ideal alternative for busy professionals. However, there are important caveats. Many commercial 'diet' soy milks contain significant amounts of sugar to improve taste. This can trigger rapid insulin secretion by spiking blood glucose, which paradoxically promotes fat accumulation. Furthermore, soy components can be taxing on the digestive system depending on one's constitution. From the perspective of Traditional Korean Medicine (TKM), individuals with 'Spleen Deficiency' (Bi-heo, 脾虛)—characterized by weakened digestive function—may experience abdominal pain or diarrhea if they consume cold soy milk. Additionally, those with an accumulation of 'Phlegm-Fluid' (Dam-eum, 痰飮) may find that excessive soy intake makes their body feel heavy and sluggish. Ultimately, the best choice depends on your unique physiological state. While I generally recommend low-sugar or unsweetened soy milk, I suggest warming it up if you typically struggle with digestion. If you would like a detailed dietary guide tailored specifically to your constitution, please visit the clinic for a personalized consultation.
