(Social strata) Inequality between social strata in nourishment

In the table linked from Hankyoreh, a model of a high-income family at the top and a low-income family in the bottom. 유=diary products, 고=meat 곡=grains, 과=fruits, 채=vegetables In an earlier post I remember thinking that the differences of healthiness of diet between social strata in Korea would not be that severe compared to the income differences, but perhaps I should correct my view. At least Hankyoreh gives the impression that the difference in the diversity and overall healthiness between income strata is severe. The diet of the low-income stratum would seem to be healthy, as they consume very little meat and dairy products, but the specialists quoted in the article tell that it leaves the nutrition inadequate. (Where does the need to consume dairy products suddenly come? ==> Where did the Koreans get their calcium earlier, or did they just suffer from the lack of it, staying short in stature?) On the other hand, those with adequate means to acquire sufficient food may suffer from both overnourishment and undernourishment. Professor Pak Hye-ryeon is quoted in the final paragraph as follows: "it's thought that obesity is the most serious nourishment problem, but the undernourishment due to low income or reckless dieting is much more serious."
