Like is it because culturally most of them are store bought? Or their preparation is based on the fact that there is a stay at home parent cooking all the time? It's just made ahead for the week? Because I love korean food, but it's a lot of cooking to have a few banchan on hand! And not a lot (if none) of these dishes can be frozen. The methodology must be very implicit for people eating this way culturally, but I just can't see to find a way not to be in the kitchen the entire afternoon if I want a full korean-inspire dinner with delicious banchan!
I'm sorry if this sound daft, I ask with the noblest intentions because I want to get better but wonder if there is a trick!

we’re feeling a little nostalgic in the office today... for a lot of us, instant ramyun was the very first meal we were ever allowed to "cook" by ourselves on the stove when we were kids.

what was your first core memory with it? who made it for you, or how badly did you mess it up—or perfect it—the first time you tried to make it yourself?

A research team led by Drs. Se Hee Lee and Tae Woong Whon at the World Institute of Kimchi, a government-funded research institute under South Korea’s Ministry of Science and ICT located in Gwangju, published findings in May 2026 in the journal Bioresource Technology identifying a strain of lactic acid bacteria called Leuconostoc mesenteroides CBA3656, isolated from traditional kimchi, as a biological agent capable of binding to polystyrene nanoplastics inside the digestive system and promoting their removal through waste. Nanoplastics are plastic particles smaller than one micrometer that form as larger plastic materials break down over time and can enter the human body through food and drinking water, with researchers increasingly concerned that these particles may cross the intestinal barrier and accumulate in organs including the kidneys and brain. The research team tested how effectively the kimchi-derived strain could attach to polystyrene nanoplastics under both standard laboratory conditions and conditions specifically designed to simulate the human intestinal environment.

Under standard laboratory conditions the kimchi strain CBA3656 achieved a nanoplastic adsorption efficiency of 87%, nearly identical to a reference strain called Latilactobacillus sakei CBA3608 which recorded 85%, suggesting comparable baseline performance between the two bacteria. The critical difference emerged when both strains were tested under simulated intestinal conditions, where the reference strain’s adsorption rate collapsed from 85% down to just 3%, while the kimchi-derived strain maintained a binding level of 57%, indicating that Leuconostoc mesenteroides CBA3656 retains functional nanoplastic-capturing ability even in the acidic, enzyme-rich environment of the human gut where most bacteria lose structural integrity. The researchers attribute this resilience to specific surface properties of the kimchi bacterium that developed through natural fermentation processes, giving it a physical and chemical compatibility with the intestinal environment that laboratory-optimized strains do not possess.

In a subsequent mouse study conducted at the WiKim facility, germ-free male and female mice that received oral doses of strain CBA3656 showed more than double the concentration of nanoplastics in their feces compared to mice that did not receive the probiotic, providing direct evidence that the bacterium promotes nanoplastic excretion through the digestive tract rather than simply binding to particles without moving them out of the body. The study adds to a growing body of evidence that microorganisms found in traditional fermented foods may interact with environmental pollutants inside the body in ways that extend far beyond their known digestive and immune functions. Researchers at WiKim stated they plan to expand the scientific investigation of kimchi microbial resources as a potential biological approach to addressing nanoplastic accumulation, which is now recognized as both an environmental and a public health crisis with no existing pharmaceutical solution.
