I'm trying to pick out some diet-friendly snacks/appetizers at a convenience store. What would a TKM doctor recommend?

I've been there—picking up snacks on the way home when hunger hits. There were many times I thought something was 'healthy enough' only to wake up the next morning with a puffy face and a groggy head. Speaking from a bit of trial and error, here is my advice. Convenience store diet snacks have clear advantages: they are highly accessible, and the calorie counts are clearly labeled, making management easier. Protein sources like low-sugar chicken breast or roasted eggs are particularly helpful for controlling weight while preserving muscle mass. However, the downsides are also distinct. Most processed foods contain high levels of sodium and additives to enhance flavor. In Traditional Korean Medicine, these ingredients can easily lead to the accumulation of 'Dameum' (痰飮)—metabolic waste or phlegm-fluid. When Dameum builds up, fluid metabolism is obstructed, leading to a heavy feeling in the body and edema (swelling). Furthermore, consuming too many cold snacks can lead to 'Bi-heo' (脾虛), or Spleen Deficiency. When the function of the Spleen (the organ responsible for digestion and transformation) weakens, digestive power drops and energy levels deplete, which can ironically trigger 'false hunger' more frequently. Therefore, there is no single 'best' food for everyone. Recommendations change entirely depending on whether you have strong digestive power or a constitution prone to swelling. I recommend first assessing your current physical state and tailoring your diet accordingly.
