What we eat matters to us – but we’re not sure whether it ought to matter to anyone else. We generally insist that our diets are our business and resent being told to eat more fruit, consume less alcohol and generally pull our socks up when it comes to dinner.The efforts in 2012-13 by New York City mayor Michael Bloomberg to ban the sale of extra large soft drinks failed precisely because critics viewed it as an intrusion into the individual’s right to make their own dietary choices. “New Yorkers need a mayor, not a nanny,” shouted a full-page advert in the New York Times. And when a school near Rotherham in northern England eliminated Turkey Twizzlers and fizzy drinks from its canteen, outraged mothers rose in protest, insisting that their children had the right to eat unhealthy food.
At the same time, many Britons are troubled by reports that as a nation their fondness for sugar and disdain for exercise will eventually bankrupt the NHS; there is considerable support for the idea that very overweight people should be required to lose weight before being treated. We agree that our poor dietary choices affect everyone, but at the same time we’re certain that we have a right to eat what we want.
The story about how we started to think this way about food is closely linked to the rise of the potato as a national starch. Britain’s love for the potato is bound up with notions of the utilitarian value of a good diet and how a healthy citizenry is the engine room of a strong economy. To find out more about that, we need to go back to the 18th century.
Enlightened eating
Today’s somewhat uneasy marriage of public health and individual choice is the result of new ideas that emerged during the Enlightenment. During the 18th century, states across Europe began to rethink the bases of national wealth and strength. At the heart of these new ideas was a new appreciation of what we would now call public health. Whereas in earlier centuries rulers wished to prevent famines that might cause public unrest, in the 18th century, politicians became increasingly convinced that national strength and economic prowess required more than an obedient population disinclined to riot.
They believed it required a healthy, vigorous, energetic workforce of soldiers and labourers. This alone would ensure the success of industry. “The true foundations of riches and power,” affirmed 18th-century philanthropist Jonas Hanway, “is the number of working poor.” For this reason, he concluded:
… every rational proposal for the augmentation of them merits our regard. The number of the people is confessedly the national stock: the estate, which has no body to work it, is so far good for nothing; and the same rule extends to a whole country or nation.
“There is not a single politician,” agreed the Spanish thinker Joaquin Xavier de Uriz, writing in 1801, “who does not accept the clear fact that the greatest possible number of law-abiding and hard-working men constitutes the happiness, strength and wealth of any state”. Statesmen and public-spirited individuals therefore devoted attention to building this healthy population. It was the productivity puzzle of the 18th century.
Clearly, to do this required an ample supply of nourishing, healthy food. There was a growing consensus across Europe that much of the population was crippling itself with poorly chosen eating habits. For instance, the renowned Scottish physician William Buchan argued this in his 1797 book Observations Concerning the Diet of the Common People. Buchan believed that most “common people” ate too much meat and white bread, and drank too much beer. They did not eat enough vegetables. The inevitable result, he stated, was ill health, with diseases such as scurvy wreaking havoc in the bodies of working men, women and children. This, in turn, undermined British trade and weakened the nation.
Feeble soldiers did not provide a reliable bulwark against attack, and sickly workers did not enable flourishing commerce. Philosophers, political economists, doctors, bureaucrats and others began to insist that strong, secure states were inconceivable without significant changes in the dietary practices of the population as a whole. But how to ensure that people were well-nourished? What sorts of food would provide a better nutritional base than beer and white bread? Buchan encouraged a diet based largely on whole grains and root vegetables – which he insisted were not only cheaper than the alternatives, but infinitely more healthful.
The marvellous spud
Buchan was one of a vast number of 18th-century potato enthusiasts. Local clubs in Finland sponsored competitions aimed at encouraging peasants to grow more potatoes, Spanish newspapers explained how to boil potatoes in the Irish fashion, Italian doctors penned entire treatises on the “marvellous potato” and monarchs across Europe issued edicts encouraging everyone to grow and eat more potatoes.
In 1794, the Tuileries Gardens in Paris were dug up and turned into a potato plot. The point is that there were an awful lot of public-spirited individuals in the 18th century who were convinced that well-being and happiness, both personal and public, could be found in the humble potato.
