I once insisted on a 'standard diet' of just chicken breast and vegetables. However, I eventually felt bloated and dizzy, realizing that this rigid approach didn't suit my own body. Sometimes, trial and error are the only ways to truly understand one's needs. Whole wheat or wheat breads are rich in dietary fiber and help slow down blood sugar spikes. However, for those with 'Bi-heo' (Spleen Deficiency)—meaning weakened spleen function and poor digestive power—these can actually be detrimental. Coarse whole grains can burden the stomach, leading to gas and gastrointestinal discomfort. Conversely, if you often feel bloated, heavy, or experience swelling, it is likely that waste products known as 'Dam-eum' (phlegm-fluid retention) have accumulated. For these individuals, I recommend using vinegar or olive oil instead of heavy sauces and incorporating a wide variety of vegetables to stimulate metabolism. Ultimately, there is no universal 'best bread.' Depending on your constitution, some find whole wheat comfortable, while others feel better with white bread. The key is to carefully observe how your body reacts to specific ingredients. If you are unsure about your current digestive state or energy levels, I suggest visiting the clinic for a constitutional diagnosis. Together, we can determine a 'personalized diet' that truly fits your unique body type.
