Humans process mostly food and ideas
When either one are tainted, there can be some very unhealthy results, for example, the International Agency for Research on Cancer (IARC), a part of the World Health Organization (WHO), recently classified processed meat and red meat as being carcinogenic to human (link) (still less of a risk than smoking cigarettes) and according to one local report, retailers in Korea saw a sharp drop in meat sales (link). While eating less red meat and eating more vegetables is great idea (IMHO), there are other local food sources that are worse than eating red meat, for example, crab organs and certain types of cephalopods (squid, octopus, etc.) contain unsafe levels of metals, notably cadmium (as used in modern batteries):
Samples of seven species of cephalopods and crustaceans were collected from major fish markets on the Korean coast and analyzed for mercury (Hg) using a direct Hg analyzer and for the metals cadmium (Cd), lead (Pb), chromium, silver, nickel, copper, and zinc using inductively coupled plasma mass spectrometry. The distributions of heavy metals in muscles, internal organs, and whole tissues were determined, and a risk assessment was conducted to provide information concerning consumer safety. The heavy metals accumulated to higher levels (P < 0.05) in internal organs than in muscles for all species. The mean concentrations of Cd, which had the highest concentrations of the three hazardous metals (Cd, Pb, and Hg), in all internal organs (except those of blue crab) exceeded the regulatory limits set by Korea and the European Union. The Cd concentrations in all whole tissues of squid and octopus (relatively large cephalopods), red snow crab, and snow crab exceeded the European Union limits. The estimated dietary intake of Cd, Pb, and Hg for each part of all species accounted for 1.73 to 130.57%, 0.03 to 0.39%, and 0.93 to 1.67%, respectively, of the provisional tolerable daily intake adopted by the Joint Food and Agriculture Organization and World Health Organization Expert Committee on Food Additives; the highest values were found in internal organs. The hazard index (HI) is recognized as a reasonable parameter for assessing the risk of heavy metal consumption associated with contaminated food. Because of the high HI (>1.0) of the internal organs of cephalopods and the maximum HI for whole tissue of 0.424, consumers eating internal organs or whole tissues of cephalopods could be at risk of high heavy metal exposure, therefore, the internal organs of relatively large cephalopods and crabs (except blue crab) are unfit for consumption. However, consumption of flesh after removing internal organs is a suitable approach for decreasing exposure to harmful metals. (link)
Meaning that certain seafood organ parts are not safe to eat though the flesh is relatively safer to eat in moderation and despite this, there are other problems with eating crabs if they have ingested algae that forms toxins. This also means that certain Korean marinated crab dishes are very likely unsafe to eat and should be avoided.
As for the ingesting of ideas, currently there is much political discussion over the Korean Government’s decision to take up regulating the content of Korean history books, specifically pertaining to history in the late 19th and 20th Centuries. There is the obvious concerns by politicians over the biased interpretation of factual information regarding Korea’s recent past, since as one Korean historian has put it, “The current textbooks contain various problems. I decided to participate (in working on the new government-regulated history texts) because I want the new textbooks to serve as an opportunity for the public to more closely approach our history based on more clear and accurate facts.” (link) The NPAD has reacted vehemently against the state-controlled revision of history books simply because they perceive this to be an attempt of certain political elements to legitimize their version of history and because they have their own interpretation of historical fact, which is based more upon their political beliefs, as opposed to fact (IMHO) . As per Moon Jae-in, head of the New Politics Alliance for Democracy (NPAD):
Pushing forward the state-penned history textbook plan is a conformist and totalitarian concept,…It denies liberal democracy.
It is odd that the government would choose this time to pursue this issue, considering the more urgent financial and social needs of Korea (household debt, chronic under-employment, economic issues). Though the Saenuri Dang claimed that they won due to public support for the Park Geun-hye government’s decision to start writing history textbooks (they wish!), it would be more accurate to say that, due to the NPAD’s focus upon ideologically-driven issues instead of developing better economic plans and strategies, the public is distrustful of their ability to help them in their daily affairs.
Considering the ruling parties attempts to trick the public into partaking of their own ideology, it might be best if actual historians were to decide how to narrate Korean history, providing they could avoid any undue pressure from political elements.
