Protein shakes have become incredibly popular for their convenience. Many people prioritize efficiency, but this often leads to digestive issues like bloating and gas if the body isn't prepared for them. The benefits are clear: they provide a quick way for busy professionals to meet essential nutrient requirements and help prevent muscle loss, which is crucial for maintaining a healthy basal metabolic rate during a diet. However, from the perspective of Traditional Korean Medicine (TKM), caution is required. If a person suffers from 'Spleen Deficiency' (Bi-heo, 脾虛)—a state where the Spleen's digestive and transport functions are weakened—excessive high-protein supplements can be counterproductive. In TKM, the Spleen is central to transforming and transporting nutrients. If this function is impaired, protein is not absorbed properly and stagnates in the gut. This can lead to the accumulation of 'Dam-eum' (痰飮), or metabolic waste/phlegm, which may cause the body to feel heavy or lead to increased edema (swelling). For those who frequently experience indigestion or irregular bowel movements, it is safer to obtain protein slowly through whole, natural foods rather than supplements. It is more important to ensure your body is ready to assimilate the nutrient than to simply ingest something perceived as 'healthy.' Ultimately, whether a supplement is 'right' for you depends on your individual digestive capacity and constitution. I suggest deciding based on whether your stomach feels comfortable or if you are forcing your body to process more than it can handle.
