Many people insist on a chicken-breast-only diet, only to find themselves suffering from chronic bloating and indigestion. The issue isn't the food itself, but whether your body is equipped to process it efficiently. From a Traditional Korean Medicine (TKM) perspective, some individuals suffer from 'Spleen Deficiency' (Bi-heo, 脾虛). For those with a weak digestive system, a sudden increase in high-protein intake can lead to the accumulation of undigested food, which transforms into metabolic waste known as 'Phlegm-Fluid' (Dameum, 痰飮). This is often why some people feel heavy or dizzy despite eating 'healthy' diet foods. While the benefits of chicken breast are clear—such as easy carbohydrate restriction and muscle maintenance—the downsides include a heavy digestive load and psychological hunger due to flavor monotony. Therefore, I recommend choosing proteins based on your current state rather than following a rigid rule. If your digestive power is low, softer proteins like white fish or tofu may be more beneficial. For those with 'Blood Stasis' (Eo-hyeol, 瘀血) causing poor circulation, pairing proteins with warm-natured vegetables is advisable. Ultimately, there is no single 'perfect food.' The priority is to assess your current digestive health and energy levels.
