Given how rapidly South Korea moved from poverty to wealth and became exposed to new world markets, you would expect the country to have moved equally rapidly to an obesogenic diet high in sugar, new fats and packaged foods. But compared to people in other rapidly developing nations, Koreans retained their traditional diet to a much greater extent. When researchers examined the data for South Korea from the 1960s to the 1990s, they were startled to find that South Korean fat consumption was still reletively low. In 1996, the typical South Korean ate less fat than the average Chinese person, even though the GNP of South Korea was at that time fourteen times higher than China’s.58 Meanwhile, levels of obesity in South Korea were also markedly lower than would have been expected from the nation’s level of economic development. As of 1998, just 1.7 per cent of men and 3 per cent of women in South Korea were obese.59
The area where South Korea bends the curve most of all is in vegetable consumption. In 1969, the average South Korean ate 271 grams of vegetables, fresh and processed, every day. In 1995, despite all the other changes to Korean society – from the strange vogue for bubble tea to the invention of K-pop, a fusion of Western and Asian pop music – the amount of vegetables Koreans ate had actually gone up slightly, to 286 grams. The city-dwelling Koreans of the 1990s led completely different lives from Korean villagers in the 1950s, yet they continued to eat their greens. The example of Korea shows that it is possible to be a modern person who is not disgusted by cabbage.60
How did South Korea manage to retain its vegetable-eating ways, despite all the other transformations and pressures of modern life? Part of the explanation is cultural. South Koreans see vegetables as something delicious rather than merely healthy, as we all too often see them in the West. Koreans enjoy a greater variety of flavoursome vegetables than most eaters in other countries, from bean sprouts to spinach. In rural Korea, it has been estimated that as many as three hundred different vegetables are eaten, each prized for its distinctive flavour and texture. King of all vegetable dishes in Korea is kimchi, a kind of fermented and highly spiced cabbage, which is not just a condiment but a staple food, the most consumed single item in the diet after rice, as of 2002.61
If Korea was helped by its vegetable-loving food culture, it also benefited from a range of government initiatives which consciously set out to soften the blow of the nutrition transition. In contrast to other developing countries, South Korea made a more concerted effort to protect its own cooking against the new globalised diet. From the 1980s onwards the Rural Living Science Institute trained thousands of workers to provide free cooking workshops educating families in how to make traditional dishes such as steamed rice, fermented soybean foods and kimchi.62 In addition, there were mass media campaigns to promote local foods, with TV programmes emphasising the higher quality of local food and the benefits of supporting home-grown produce and local farmers. When most children in the 1980s switched on the TV, they would be greeted by adverts for sweets and treats, fizzy drinks and cereals. When Korean children watched TV, they might instead be fed with government-endorsed messages on the benefits of locally grown food.63
Fast forward to the present day, and the average South Korean diet is no longer quite as healthy as it was in the 1990s. When Popkin returned to look again at the data on Korean diets in 2009, he found that consumption of both alcohol and soft drinks was on the rise. From the late 1990s to 2009, the Korean government put a decade of effort into promoting the consumption of wholegrains, yet the average person only ate around sixteen calories more of wholegrains than before. The message this time was less effective. The prevalence of obesity, diabetes and heart disease in South Korea were also much higher in 2009 than ten years earlier.64
Vegetable consumption in Republic of Korea, 1969–2009, grams per person per day.
Yet Koreans still eat far more vegetables than people in most other wealthy countries and kimchi is as popular as it has ever been. This is all the more remarkable considering that the price of cabbage – the main ingredient in kimchi – rose by 60 per cent between the 1970s and 2009. The average South Korean diet might not be perfect – what human diet ever has been? – but South Korea remains as remarkable proof that it is possible to attain some kind of golden midway point between the wholesome but too-scarce diets of the past and the plentiful but unhealthy diets of the present.65
What South Korea shows is that the curve of the nutrition transition can be bent, at least slightly, with the right interventions from government. This offers hope to the developing countries of sub-Saharan Africa. Perhaps they, too, will be able to retain the best aspects of their vegetable-centric and varied diets while enjoying lives of greater comfort, wealth and ease.
At the time of writing, however, it is doubtful whether the governments of other developing countries will follow the South Korean route in actively trying to fight the onslaught of packaged foods. The more common approach seems to be for governments not so much to fight the nutrition transition but to try to make it curve faster, to gain from the profits of multinational food companies.
In August 2017, I was in Copenhagen for the World Food Summit, a two-day conference aimed at finding better ways for the world to feed itself. One of the speakers was Harsimrat Kaur Badal, the Minister for Processed Foods in India’s government (I never knew such a job existed). Badal stood up and gave a passionate speech lamenting the Indian attachment to freshly cooked food made from fresh vegetables. India, she said, was a country where most people still ate three home-cooked meals a day. The audience of Danish and international food writers, chefs and representatives from the food industry let out a mild sigh of envy. Oh for the fresh-cooked food of India! But the minister was trying to explain to us that this fresh and delicious food was actually a very bad and wasteful thing. ‘We only process 10 per cent of the food we produce in India,’ she lamented. She compared this to the countries of Western Europe, where around 60 per cent of food is processed. The minister made the point – quite reasonably – that the middle classes in India wanted to eat the same foods that were available to people with money in the rest of the world. She also pointed out that India wastes $40 billion worth of food every year, mostly because of inefficient distribution networks. ‘Food waste is morally wrong.’ The answer, she suggested, was foreign direct investment (FDI) in processed food.
India was a gigantic business opportunity, the minister explained. It was a market of 1.4 billion people, whose potential as consumers of processed food was still largely untapped. ‘I invite you all to come and partner with my country,’ she announced. ‘We want you to teach us your Danish technology and knowhow.’ In return, she offered India’s amazing ingredients and a ‘platform’ of customers ripe for the picking.
Is this really the route that the governments of India and other developing countries want to take through the nutrition transition? India is a country with a long-standing love of vegetables, which has the potential to experience something like the South Korean version of stage four, rather than the health-destroying version seen almost everywhere else. Rising incomes in India are a wonderful and life-changing thing, on so many levels. But already, as India welcomes more ultra-processed food into its diet, the country is seeing an alarming rise in type 2 diabetes and insulin resistance. Is there a way for India to enjoy life beyond hunger without having to suffer the diseases of affluence?
What we ate next
Based on everything we know about history, stage four will not be the final phase of the nutrition transition, but no one can say for sure what future diets will look like. One thing that seems certain is that after fifty years or more of over-consumption there will have to be some kind of shrinking back in the amount of calories populations consume. What remains to be seen is whether this reduction will be forced upon us by climate change and failing harvests, or whether we can take control of our own food destiny and start to eat within the limits of what our bodies need and what the land can bear.
