Eat This Podcast

jcherfas@mac.com (Jeremy Cherfas)

Using food to explore all manner of topics, from agriculture to zoology. In Eat This Podcast, Jeremy Cherfas tries to go beyond the obvious to see how the food we eat influences and is influenced by history, archaeology, trade, chemistry, economics, geography, evolution, religion -- you get the picture. We don't do recipes, except when we do, or restaurant reviews, ditto. We do offer an eclectic smorgasbord of tasty topics. Twice nominated for a James Beard Award.

    Quinoa’s rise and fall

    Portrait of a young woman with shoulder-length light brown hair. She is wearing a dark round-necked top and a necklace.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 illusion.

    Emma McDonnell was in Peru for the early years of the boom and for the subsequent bust, a story she recounts in her book The Quinoa Bust.

    Notes

    1. Emma McDonnell has a website. Her book The Quinoa Bust: The Making and Unmaking of an Andean Miracle Crop is published by California University Press.
    2. A previous episode — It is OK to eat quinoa — looked at the impact of the boom in purely economic terms.
    3. An issue of the USDA’s Choices magazine looked at several so-called functional foods, including quinoa, asking whether they were a Fad or Path to Prosperity?. Both, maybe.

    Forbidden: Jews and the Pig

    An advertisement for Burger King kosher "bacon" in Israel. A smiling young man wearing a Burger King paper crown holds a "bacon" burger. He has the long sidelocks that signify an observant religious Jew.

    Head and shoulders portrait. A smiling man with spectacles, short gray hair and a long gray beard, wearing a blue check shirt and riddish tie.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 still survives in anti-semitic propaganda.

    I didn’t want to rehash the history of anti-semitism but I did want to know more about the relationship between pork and Jewish identity. I hope you will too.

    Notes

    1. Forbidden: A 3,000-Year History of Jews and the Pig is published by New York University Press.
    2. Jordan D. Rosenblum is the Belzer Professor of Classical Judaism at the University of Wisconsin-Madison.
    3. Cover art is a reproduction from a 19th century book about customs of the Middle Ages. The banner image is from a campaign by the Debby Agency for Burger King. I am told (by ChatGPT) that the Hebrew says “And may the house be filled with the smell of turkey bacon”.

    Food facts are not the answer to fear of foods

    A cartoon of a sterotypical Mom and a stereotypical food scientist shouting at one another through megaphones

    Portrait of a msiling woman with curly medium length hair in front of an abstract orange and yellow backgroundCharlotte 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 questions of safety and risk, will buy and eat its products. People want answers to questions beyond safety and risk. And never the twain shall meet.

    Notes

    1. Real Food, Real Facts: processed food and the politics of knowledge is available from the University of California Press.
    2. Other effects notwithstanding, a primary reason to avoid UPFs is that they encourage you to eat more.

    Food, folklore and St Brigid

    Five different St Brigid crosses

    An icon of St Brigid wearing a blue cloak and with symbols of food and farming

    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 designs, using them to protect farm animals and ensure a good harvest. There are special foods too, and other ritual celebrations, some of which delve in the pagan past.

    Caitríona Nic Philibin has studied the folklore surrounding St Brigid and shared some of the stories with me.

    Notes

    1. I am indebted to Caitríona Nic Philibin and Máirtín Mac Con Iomaire for their work on food and folklore in Ireland, and especially An exploratory study of food traditions associated with Imbolg (St. Brigid’s Day) from The Irish Schools’ Folklore Collection. They offered a summary of their work: What food is associated with St Brigid’s Day?. And Pishogues, Brídeogs And Butter Witches at The Common Table gives a great deal more detail on food and folklore in Ireland.
    2. The music at the start is from St. Brigid’s Jig by Louise Mulcahy. Another fine tune from the same set is St. Brigid’s Day by Caitlín Nic Gabhann.
    3. Images of St Brigid’s crosses from the National Museum of Ireland. The icon of St Brigid I lifted from The Brigidine Sisters.

    Sensual, Salty, and a Little Bit Spicy

    Two Gilda pintxos with a long green pepper, a glistening anchovy and a green olive skewered on a long toothpick in a wooden block, against a black background.

    Still life with anchovies by Antonio Sicurezza. A pile of silvery anchovies on a yellow table with a frying pan in the top right corner and some garlic bottom right.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 time I spoke to Marcela Garcés, we didn’t have time to talk about the Gilda. This episode fixes that omission.

    I also had to contact Chris Beckman again, to see if he could enlighten me on what he calls the Swedish Anchovy Conundrum.

    Notes

    1. Here, again, is Marcela Garcés’ paper: In Defense of the Anchovy: Creating New Culinary Memories through Applied Cultural Context.
    2. Christopher Beckman’s book is A Twist in the Tail: How the Humble Anchovy Flavoured Western Cuisine.
    3. What’s in a name? Mislabeling fish since the 16th century offers more information of the history of Swedish “anchovies”.
    4. Here is the transcript.

    Better Diets for All

    Supermarket shelves crammed with colourful packages converging on a vanishing point in the far distance.

    A today world globe on a plate with a knife and fork, all on a multicoloured striped table mat.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 group of researchers in the UK. They argue that “a fresh approach is needed, one that considers the full picture of people’s realities”. Corinna Hawkes, lead author on the paper, took me through some of those realities.

    Notes

    1. The published paper is The full picture of people’s realities must be considered to deliver better diets for all.
    2. The earlier podcast, with Corinna Hawkes, Patrick Webb and Eileen Kennedy is We need to talk about diets.

    Bennett’s Law

    Graphic illustration showing stylised images of pearl millet, rice, chicken and chickpeas, an indication of Bennett's Law

    Graphic illustration of a rainbow hand holding a bag of money, symbolised by a dollar sign, from which are sprouting green leaves.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 no-one had actually studied income and food purchases under controlled conditions.

    Now someone has, with the first empirical test of Bennett’s Law. For Marc Bellemare, the lead author, the research, “changes your view of how the world works”.

    Notes

    1. Income and the Demand for Food among the Poor, by Marc F. Bellemare, Eeshani Kandpal, and Katherina Thomas can be downloaded from JSTOR.

    The Cost of a Healthy Diet
    Four people on a terrace with trees and buildings in the background.Anna Herforth, Imran Chiosa Will Masters, and Olutayo Adeyemi

    Cover artwork, A plate of money with a green smoothie in a glass at top left.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 collecting (to compile their Consumer Price Index) and from them calculate the cost of a healthy diet. The results have been alarming for some policy-makers, with encouraging results in at least one country.

    Anna Herforth, who first told me about the cost of a healthy diet in 2021, was in Rome recently for a workshop on diet cost metrics with her colleagues Will Masters, who leads the Food Prices for Nutrition team, Olutayo Adeyemi, from Nigeria, and Imran Chiosa from Malawi. A chance too good to miss, despite the roar of the traffic beneath us.

    Notes

    1. The website of Food Prices for Nutrition offers more detailed explanations and links to other places where the data are being used. This one lets you see the numbers for each country; the surprise is that even in high-income countries, large numbers of people cannot afford a healthy diet.
    2. The first episode on this topic was The cost is too damn high.

    Anchovies Part 2

    A blur of fresh silvery anchovies on ice being unloaded

    Author Chris Beckman holding an anchovy on a toothpick in one hand and a bowl in the other. He is wearing a blue button-down shirt and looking into the camera.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, when Italians, expert in the ways of salting fish, fetched up on the Basque coast to buy up all the fish that nobody else wanted. Among them, Giovanni Vella, who invented the modern tin of anchovy fillets in olive oil.

    It was, according to Chris Beckman, author of A Twist in the Tail: how the humble anchovy flavoured Western cuisine, a win for everyone.

    Notes

    1. Christopher Beckman’s A Twist in the Tail: How the Humble Anchovy Flavoured Western Cuisine is published by Hurst & Co.
    2. If you haven’t already heard it, the previous episode celebrates the anchovy in modern Spain.

    Anchovies Part I

    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 run La Centralita, a culinary studio that aims, among other things, “to teach guests about anchovies as a gourmet food in context”. As a result of our conversation, I now hold anchovies in even higher regard.

    Notes

    1. Marcela Garcés’ paper is In Defense of the Anchovy: Creating New Culinary Memories through Applied Cultural Context.
    2. La Centralita is in Albany, New York.

    Crunch Time: Insects Are Not Going to Save Us

    Adult black soldier flies mating on a green leaf. The insects are tail to tail and joined by the male's penis.

    Cover artwork; a bowl of reddish rice, possibly with tomato, scatterd with a few darker black soldier fly larvae and a green parley or coriander leaf.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 that insects are fed isn’t waste at all, and after absorbing large amounts of investor cash, some of the biggest companies have gone bust. Dustin Crummett, executive director of the Insect Institute, shared his many reasons for saying that eating insects will not save the planet.

    Notes

    1. Dustin Crummett is executive director of The Insect Institute. His paper: Is turning food waste into insect feed an uphill climb? A review of persistent challenges.
    2. If not food or feed, how about “valuable raw materials for various industries”?
