I eat Subway sandwiches often for my diet. Which cheeses and sauces should I choose?

I also occasionally rely on sandwiches when I'm busy. However, I've noticed that after eating them, I sometimes feel bloated or lightheaded. Through my own experience and analysis, I found that the primary issues are often the 'sauces' and the individual's 'constitution' (Sasang typology). On the positive side, Subway is excellent for dietary fiber intake due to the abundance of fresh vegetables. Cheese also provides a moderate amount of protein and fat, which helps maintain satiety. However, there are key precautions. First, sweet sauces can cause rapid spikes in blood glucose, which may actually increase appetite. Second, from the perspective of Traditional Korean Medicine, a diet centered on cold, raw vegetables can be detrimental to those with 'Bi-heo' (Spleen Deficiency), where digestive function is weakened. Specifically, if you have accumulated 'Dam-eum' (phlegm-fluid retention/metabolic waste), consuming cold foods can further chill the body and hinder circulation. For those with 'Eo-hyeol' (blood stasis), poor blood flow can make weight loss feel significantly slower. Ultimately, there is no single 'correct' answer. While this may be the perfect diet for some, it can cause digestive distress for others. It is crucial to first understand your own digestive health and constitution. I encourage you to visit the clinic to check your current physical state and discuss a personalized dietary plan that suits your body.
