Dr Joseph GoldbergerPellagra — a terrible disease characterised by the four Ds: dermatitis, diarrhoea, dementia and death — was first noticed in northern Spain in 1735 and in Italy soon afterwards. Physicians had no idea what to do about it. They established that it was a new disease, and quickly worked out that it was something to do with maize and that it seemed to afflict only very poor people. In Italy, sharecroppers grew and ate maize at the expense of any vegetables. And in the southern US...

Alessandro Biavati, chef. Quite by chance, I booked a brief cycling holiday at an agriturismo based on a farm that is home to Quin Italia, an enterprise that aims to be the first supply chain for certified organic quinoa grown in Italy. The food at the agriturismo was excellent, as it usually is, but there were only two items on the menu that featured quinoa: a beer and a plate of deep fried croquettes that owed more to chickpeas than to quinoa. That was just one of the points I raised with Ales...

Many countries have strict rules about who is allowed to give advice on diet and nutrition, but that doesn’t stop even qualified people from selling all kinds of snake oil. In this episode, I chatted with Tara Schmidt, a registered dietitian and lead dietitian for the Mayo Clinic Diet. We talked about fad diets, and how they are inevitably unsustainable. About weight-loss drugs and whether they are being oversold. About the frustration she feels faced with bad advice, and how the Mayo Clinic’s c...

Flavia Giordano and Carla the Italian greyhound Puglia is massive. I mean that quite literally, not as youthspeak, though that too. Its northernmost point is actually north of my home in Rome, though admittedly not by very much, which is strange when you consider that for most people, Puglia is only the high heel itself. That’s true for me and for several past episodes here. A new book that explores the whole province, and more particularly its food and ingredients, flashed through my feeds a fe...

For much of the world, food has never been as abundant or as inexpensive as it is now, but at what cost? The Food and Agriculture Organization estimates that the cost of diet-related ill health is somewhere around $7 trillion, which is far more than the “profits” of food and agriculture. Those profits, like the cheaper, more plentiful food they stem from, take no account of the external costs of climate change, pollution, biodiversity loss and, ultimately, human health. Professor Tim Benton has ...

Jennifer ClappThe top four companies globally control more than 60% of the inputs modern farmers need: machinery, fertilisers, seeds, and pesticides. That kind of concentration, coupled with their size, gives these companies unprecedented power to set prices, often in collusion with their “competitors,” to block real competition, to stifle innovation, and to manipulate governments and policies. And while that may seem a problem of modern times, it’s actually a story that goes back to the beginni...

Emma McDonnellFor most of the 2000s, farmers in Peru earned a little more than one sol per kilogram of unprocessed quinoa they sold. Starting around 2007, the price began to climb as quinoa exports became a thing, averaging 9 soles per kg in 2014. The following year, the price halved, and it dropped again in 2016. It’s still around 4 soles per kg, so a lot better than it was, and quinoa production is double what it was. Nevertheless, the early promise of a sustained quinoa boom proved to be an i...

Jordan RosenblumPerhaps the only thing most people know about Jewish dietary laws is that pork is forbidden. A new book asks why the pig — rather than any of the other animals banned by the Hebrew bible — should have become so inextricably bound up with Jewish identity. Author Jordan Rosenblum points out that at the time of the Roman occupation, the pig was “simply the most commonly encountered nonkosher quadruped.” The imagined qualities of the pig and those of the Jews aligned, a link that sti...

Charlotte Biltekoff A new book takes a close look at people’s concerns about processed foods and how the processed food industry has failed to respond to them. The author, Charlotte Biltekoff, says she wanted to try and understand what was happening around her, as people in her milieu came more and more to demand real food rather than processed foods, while the makers of processed foods failed to understand the deeper reasons underpinning those demands. Industry wants consumers who, reassured on...

St Brigid of Kildare is one of the three patron saints of Ireland and has a strong connection with food and farming. St Brigid’s day falls on 1 February and traditionally marks the beginning of spring and the start of the agricultural year. In 2023, the Republic of Ireland designated the day a public holiday if it falls on a Friday, and failing that the first Monday of February, but the day has long been celebrated in a variety of ways. People make St Brigid’s crosses to a variety of traditional...

No apologies for once again casting my net in the fruitful waters of Basque cuisine and history. There is a pintxo — those tasty bites of stuff on a toothpick — that consists of a plump Cantabrian anchovy, a pickled guindilla pepper and an olive. Some people reckon it is the original pintxo, invented by one of the regulars at a bar in San Sebastián. Others are not so sure. Everyone agrees, however, that it owes its name — the Gilda — to Rita Hayworth, who starred in the movie of that name. Last ...

A thorough trawl in 2020 brought to light more than 40 different kinds of policies around the world designed to improve diets to deliver better nutrition and health. And yet, the vast majority of people do not eat within dietary guidelines. If anything, diets — and with them health — are getting worse in many places. What’s the problem? Maybe, it is that the people who devise the policies are too far away from the lives of the people they’re trying to help. That’s the gist of a new paper from a ...

For a long time people have suspected that there is a kind of logic to what people buy as they have a bit more to spend on food. First, they change from coarse grains — things like sorghum or millet — to fine grains, wheat and rice, maybe corn. Then they switch up to protein from animal-sourced foods. This logic was even considered something of a law, Bennett’s Law, after Merrill Bennett, the agricultural economist who formulated the idea in the early 1940s. But it wasn’t really a law, because n...

Anna Herforth, Imran Chiosa Will Masters, and Olutayo Adeyemi Let’s assume that people understand what they ought to eat to keep themselves healthy over the course of their lives and that the nutritious food to deliver good health is available in the market. More than one in three of the world’s people simply cannot afford a healthy diet. We know because the Food Prices for Nutrition team at Tufts University has developed tools that allow countries to use data that most of them are already colle...

The Spanish are the world’s greatest anchovy eaters. They get through about 2.69 kilograms each a year, more than a tin a week. So you might be forgiven for thinking that anchovies have always been a part of Spanish cuisine. Not so, with the exception of the good people of Malaga, who developed a thing for deep-fried fresh anchovies. The rest of Spain resolutely ignored anchovies as food, spreading them instead on their fields as fertiliser. All that started to change in the late 19th century, w...

Marcela Garcés Anchovies can be very divisive; some people absolutely cannot stand them. I can’t get enough of the little blighters. What’s the difference? It might be as simple as the way they’re stored. At the Dublin Gastronomy Symposium this past summer, I was delighted to learn one crucial way to improve any tin of anchovies: keep it in the fridge until you’re ready to use it. Marcela Garcés is a professor at Siena College in New York, and as a side hustle she and her husband Yuri Morejón ru...

If only we could get over our squeamishness, insects can save the planet, banish hunger, protect the rainforests and reduce the climate catastrophe. At least, that’s what article after article tell us as they sing the praises of feeding our food waste to insects like the larvae of the black soldier fly. Insects can grow 5000-fold in 12 days, producing prodigious quantities of protein in less than 100th the space of soya beans. There’s just one fly in the ointment, so to speak. Most of the food t...

Silvestro Silvestori stands in front of some of the metal cans of his varietal olive oils. Xylella fastidiosa is a bacterium that attacks all manner of plants. It prevents water getting to the leaves, so the plant essentially dies of drought. It probably arrived in Italy in 2008 but wasn’t really noticed until 2013, attacking a few trees around the town of Gallipoli in the Salento, the heel of the boot of Italy. Thanks to badly botched responses it spread, carried by spittlebug insects that live...

Water is tricky stuff. It can be limpid and clear but dangerous, home to harmful bacteria and parasites. It can be murky, but perfectly safe to drink. It may smell of chlorine, which puts people off, but perversely that is a sign that no bacteria are present. So how do we judge the quality of water? That’s the subject of a new book — The Taste of Water — by Christy Spackman at Arizona State University. She looks at the history of water purification and efforts to understand the complex interplay...

Cheap supermarket meat has been making life difficult for independent butchers for quite some time now. England has lost 60 per cent of its butcher shops in the past few decades, Australia 80 per cent. I couldn’t find figures for the United States. Against that background, there has been an uptick of interest from young people wanting to learn the skills needed to deconstruct an animal carcass. What surprised me – and of course it shouldn’t have – is that women are learning butchery. I chatted w...

Eleanor Barnett We all know we’re supposed to reduce our food waste, but what exactly is the difference between waste and leftovers? For me, leftovers become waste when they turn green and furry, forgotten at the back of the fridge, but that’s a very narrow view. Eleanor Barnett is a historian whose book Leftovers: a history of food waste and preservation takes a much broader look at food scarcity, food surpluses and the byproducts of food production that people don’t or won’t eat. Our conversat...

One of the key activities in an observant Jewish household’s preparation for Passover is the hunt for and destruction of chametz, anything that involves leavened grain. At one level, the search means that the house gets an extremely thorough cleaning at least once a year. At another, there are associations that equate ridding the house of chametz with ridding the mind of ego and other spiritual concerns. But what exactly is chametz? In trying to get to some sort of “truth” I discovered that ther...

The last supper was a Passover Seder, and for two thousand years Passover and Easter have been linked. The links, however, are complex, which is why I am taking the opportunity to expand on a five-year-old episode. The rituals of the Passover dinner have been in place for thousands of years, although always open to interpretation and evolution. And yet, although different Christian traditions have their ritual Easter foods, there don’t seem to be any universals. The episode looks at these two co...

Malta, just off the coast of Sicily in the middle of the Mediterranean, has always been of enormous strategic importance. As a result it has been claimed, and fought over, by empire after empire. Each time it was vulnerable to a blockade of essential food supplies because the tiny island — Malta is only 27 kilometres long — cannot possibly feed itself. Despite this history, going into World War II neither the British colonial government nor the Maltese people were prepared for the inevitable blo...

Spina bifida is a neural tube defect that is one of the most common severe birth defects in the world. The main cause is a lack of folate vitamin in the diet, and in 1991, the UK’s Medical Research Council halted a trial of folic acid supplementation early because it was obvious that the supplement was preventing a large number of cases. At the time, the trial’s authors concluded: “public health measures should be taken to ensure that the diet of all women who may bear children contains an adequ...

But it was the incidental asides Anthony dropped in the documentary, along with a look at Formaggio Cheese, the company he built, that really made me want to talk to him about his family of ch...

Harry RobsonSix thousand years ago in northern Europe, the first Neolithic farmers were bumping up against Mesolithic people, who made a living hunting and fishing and gathering wild plants. Both groups of people made ceramic cooking vessels for their food, and those pots have now revealed that in many respects the diets of the two cultures were more alike than different. The hunter-gatherers were processing dairy foods, while the farmers were cooking fish and other aquatic resources. That’s the...

In the 1950s and 1960s, the paediatric establishment in America convinced mothers to start solid foods in the first month of baby’s life, and sometimes even before they had left the hospital. This was considered a good idea even though the average baby wouldn’t have a tooth in its head for another five or six months. Amy Bentley, a professor at New York University, has charted the rise and continuing rise of baby food, from its earliest emergence in upstate New York and Michigan to its prolifera...

Twenty-five years later, her article in Art of Eating shared her discoveries about a spice essentially unknown even in India, one that makes a very elusive contribution to flavour, best described as “you know it when it’s missing”. Priya Mani eventually identified the strange thing in her soup as a li...
