When dieting, opting for sugar-free options like an Americano or tea is an excellent starting point. However, from the perspective of Traditional Korean Medicine, coffee is a double-edged sword. Its characteristic bitter taste helps descend 'Floating Qi' and temporarily boosts metabolism, effectively assisting the body in discharging 'Damp-Phlegm' (metabolic waste) through urination. This can temporarily make the body feel lighter. On the flip side, coffee is warm and dry in nature, which can deplete 'Body Fluids' (Jin-yeok)—the essential moisture our bodies require. For those with 'Spleen Deficiency' (Bi-heo) who struggle with digestion, or those prone to 'Heart Palpitations' (Sim-gye), coffee can be counterproductive. If you feel heavy and swollen in the morning, an Americano may help jumpstart your metabolism. However, if you experience a dry mouth or 'False Heat' (Heo-yeol) in the afternoon, caffeine-free tea is a much better choice. The key is to maintain the balance of 'Yin and Yang.' If your diet is making you feel particularly sensitive or exhausted, I recommend looking beyond your beverage choice and carefully examining your overall digestive health and Vital Energy (Qi) status.
