Editing the recent podcast on Antibiotics in agriculture was far harder than I expected it to be, mostly because I had to cut away stuff that is important, but just didn’t fit. Much of that was about how, in time honoured tradition, antibiotic manufacturers and veterinarians sowed doubts about who...
I love that Jeremy goes to the effort to not only analyze the charts and graphs, but finds original copies and brings them to our attention. Too often people would look at such things and take them at face value.
This is definitely a podcast “extra”, but I’m glad he spent the time to bring up the other interesting topics that didn’t make the original episode.
Tackling the problem of antibiotic resistance at (one) source
In the past year or so there has been a slew of high-level meetings pointing to antibiotic resistance as a growing threat to human well-being. But then, resistance was always an inevitable, Darwinian consequence of antibiotic use. Well before penicillin was widely available, Ernst Chain, who went on to win a Nobel Prize for his work on penicillin, noted that some bacteria were capable of neutralising the antibiotic.
What is new about the recent pronouncements and decisions is that the use of antibiotics in agriculture is being recognised, somewhat belatedly, as a major source of resistance. Antibiotic manufacturers and the animal health industry have, since the start, done everything they can to deny that. Indeed, the history of efforts to regulate the use of antibiotics in agriculture reveals a pretty sordid approach to public health.
But while it can be hard to prove the connection between agriculture and a specific case of antibiotic resistance, a look at hundreds of recent academic studies showed that almost three quarters of them did demonstrate a conclusive link.
Antibiotic resistance – whether it originates with agriculture or inappropriate medical use – takes us back almost 100 years, when infectious diseases we now consider trivial could, and did, kill. It reduces the effectiveness of other procedures too, such as surgery and chemotherapy, by making it more likely that a subsequent infection will wreck the patient’s prospects. So it imposes huge costs on society as a whole.
Maybe society as a whole needs to tackle the problem. The Oxford Martin School, which supports a portfolio of highly interdisciplinary research groups at Oxford University, has a Programme on Collective Responsibility for Infectious Disease. They recently published a paper proposing a tax on animal products produced with antibiotics. Could that possibly work?
Here’s another great example of a negative externality. Too often capitalism brushes over these and creates a larger longer term cost by not taking these into account. It’s almost assuredly the case that taxing the use of these types of antibiotics across the broadest base of users (eaters) (thereby minimizing the overall marginal cost), would help to minimize the use of these or at least we’d have the funding for improving the base issue in the future. In some sense, the additional cost of eating organic meat is similar to this type of “tax”, but the money is allocated in a different way.
Not covered here are some of the economic problems of developing future antibiotics when our current ones have ceased to function as the result of increased resistance over time. This additional problem is an even bigger worry for the longer term. In some sense, it’s all akin to the cost of smoking and second hand smoke–the present day marginal cost to the smoker of cigarettes and taxes is idiotically low in comparison to the massive future cost of their overall health as well as that of the society surrounding them. Better to put that cost upfront for those who really prefer to smoke so that the actual externalities are taken into account from the start.
In the town hall of Siena is a series of glorious frescoes that depict The Allegory of Good and Bad Government. In one of them is a pig, long snouted and thin legged, black with a white band around its back and down its front legs, being quietly chivied along by a swineherd. It is absolutely recognisable as a cinta senese, a Belted Sienese pig, today one the most favoured heritage breeds in Italy. But it wasn’t always so. Numbers dropped precipitously in the 1950s and 1960s, to the point that the herd studbook, recording the ancestry of all the animals, was abandoned. And then began the renaissance.
One place that contributed to the revival of the cinta senese is Spannocchia, a large and ancient estate not far from Siena. I was lucky enough to visit earlier this summer, to see the pigs first hand and to learn about them from Sara Silvestri.
Perhaps the biggest surprise, to me, was that not all cinta senese are blessed with the white belt that is deemed a characteristic of the breed. Some have white spots or stripes but not the full band, and some don’t seem to have any white at all. This could be flaky genetics – odd for a breed with a supposedly ancient lineage – or it could be the result of marauding male cinghiale, which are a problem in Spannocchia and elsewhere. Right now, all these visually defective animals (and most of the perfect specimens too) end up on a plate. I wonder how long before every piglet born is properly belted.
Oh, how I dream of pork… I’m beginning to wonder if there’s an Eat This Podcast 12 step program.
For a minute toward the end I though that Jeremy had slipped and let the audio quality of the episode go to pot. Took me a minute to realize that it had started to rain during the interview and the audio was really just supplementing the arc of the story–as always. I suppose I have to let go and trust his producerial sense.
I’d been away from podcasts for a chunk of the summer, so today was a great day to have the chance to catch up on one of my favorites.
What is jam? “A preserve made from whole fruit boiled to a pulp with sugar.” Lots of opportunities to quibble with that, most especially, if you’re planning to sell the stuff in the UK and label it “jam,” the precise amount of sugar. More than 60% and you’re fine calling it jam. Less than 50% and you need to call it reduced-sugar jam. Lower still, and it becomes a fruit spread. All that is about to change though, thanks to a UK Goverment regulation that will allow products with less than 60% sugar to be labelled jam.
There’s nothing like a threat to the traditional British way of life to motivate the masses, although as an expat, I had no idea of the kerfuffle this had raised until I read about it on the website of the Campaign for Real Farming.
I realize that I’m probably ruined by eating soft set American jams and jellies all my life, aside from a half a dozen or so homemade versions I’ve made myself over the years. Here in the states, we’ve slipped even further–most jams are comprised of high fructose corn syrup instead of sugar. If only that revolution had happened after the 1920s instead of the 1770s perhaps things would be different.
I’m curious what’s become of this issue four years on? Did the “hard”-liners win out, or did the regulations turn to (soft set) jelly?
Karen Coates is a freelance American journalist who writes about food – among other things. She emailed to ask if I would be interested in talking to her about a book that she and her husband, photographer Jerry Redfern, have produced. It’s called Eternal Harvest, but it isn’t about food, at least not directly. Its subtitle is the legacy of American bombs in Laos. Some of those bombs are 500-pounders. Lots of them are little tennis-ball sized bomblets, which are as attractive to farm kids as a tennis ball might be, with horrific consequences. The story of unexploded ordnance in Laos was an eye opener, for me. But I also wanted to know about food in Laos, and so that’s where we began our conversation.
Interesting to hear about the monotony of some of the local diets, which across large areas are actually quite diverse. The limited selections show a high incidence of forced locovorsim while the lack of diversity also goes to show limited trade areas and links between towns and villages. The show also touched on some longer 500 year trends in food in the area, but only in a passing manner. Even small amounts of animal protein in diets shows how important they can be in the long run.
Ah, the self-indulgent joy of making a podcast on one of my own passions.
“They” say that turning cooking from an enjoyable hobby into a business is a recipe for disaster, and while I’m flattered that people will pay for an additional loaf of bread I’ve baked, there’s no way I’m going to be getting up at 3 in the morning every day to sell enough loaves to make a living. But there are people who have done just that, and one of them happens to be a friend. Suzanne Dunaway and her husband Don turned her simple, delicious foccacia into Buona Forchetta bakery, a multi-million dollar business that won plaudits for the quality of its bread – and then sold it and walked away.
Suzanne was also one of the first popularisers of the “no-knead” method of making bread, with her 1999 book No need to knead. Using a wetter dough, and letting time take the place of kneading, has been around among professional bakers and some, often forgetful, amateurs for a long time, but it was Mark Bittman’s article in the New York Times that opened the floodgates on this method. Since then, as any search engine will reveal, interest in the technique has exploded, both because no-knead is perceived as easier and because the long, slow rise that no-knead usually calls for results in a deeper, more complex flavour. I’ve had my troubles with it, and had more or less given up on the real deal. But I’m looking forward to seeing how a quick no-knead bread turns out, especially now that I know that in Suzanne’s case it was the result of a delicious accident.
Yet another episode that I would have listened to for hours if it had gone on. It reminds me how sad it is that they’ve moved out of LA and La Brea Bakery has become so huge. It also reminds me of fond days back on Barry Avenue in my “youth”. I’m always one to daydream about having my own pastry shop, but the repeated instances of 3AM start times reminds me why I don’t do this.

A fascinating tool for exploring how, where and when diets evolve. Foodwise, what unites Cameroon, Nigeria and Grenada? How about Cape Verde, Colombia and Peru? As of today, you can visit a website to find out. The site is the brainchild of Colin Khoury and his colleagues, and is intended to make it easier to see the trends hidden within 50 years of annual food data from more than 150 countries. If that rings a bell, it may be because you heard the episode around three years ago, in which Khoury and I talked about the massive paper he and his colleagues had published on the global standard diet. Back then, the researchers found it easy enough to explain the overall global trends that emerged from the data, but more detailed questions – about particular crops, or countries, or food groups – were much more difficult to answer. The answer to that one? An interactive website.
While this seems a short and simple episode with some engaging conversation, it’s the podcast equivalent of the floating duck–things appear smooth and calm on the surface, but the duck is paddling like the devil underneath the surface. The Changing Global Diet website is truly spectacular and portends to have me losing a day’s worth of work or more over the next few days.
I’d be curious to see what some of the data overlays between and among some of these projects looked like and what connections they might show. I suspect that some of the food diversity questions may play into the economic complexities that countries exhibit as well.
If there were longer term data over the past 10,000+ years to make this a big history and food related thing, that would be phenomenal too, though I suspect that there just isn’t enough data to make a longer time line truly useful.

What, really, is the point of conserving agricultural biodiversity? The formal sector, genebanks and the like, will say it is about genetic resources and having on hand the traits to breed varieties that will solve the challenges tomorrow might throw up. Thousands of seed savers around the world might well agree with that, at least partially. I suspect, though, that for most seed savers the primary reason is surely more about food, about having the varieties they want to eat. David Cavagnaro has always championed that view. David’s is a fascinating personal history, which currently sees him working on the Pepperfield Project, “A Non-Profit Organization Located in Decorah, IA Promoting and Teaching Hands-On Cooking, Gardening and Agrarian Life Skills”. I first met David 15 or 20 years ago at Seed Savers Exchange in Decorah. This year, I was lucky enough to be invited there again, and I lost no time in finding time for a chat.
David pointed out that immigrants are often keen gardeners and, perforce, seed savers as they struggle to maintain their distinctive food culture in a new land. That’s true for the Hmong in Minneapolis, Asian communities in England and, I’m sure, many others elsewhere. What happens as those communities assimilate? The children and grandchildren of the immigrant gardeners are unlikely to feel the same connection to their original food culture, and may well look down on growing food as an unsuitable occupation. Is immigrant agricultural biodiversity liable to be lost too? Efforts to preserve it don’t seem to be flourishing.
Seed saving for its own sake, rather than purely as a route to sustenance, does seem to be both a bit of a luxury and to require a rather special kind of personality. John Withee, whose bean collection brought David Cavagnaro to Seed Savers Exchange and people like Russ Crow, another of his spritual heirs, collect and create stories as much as they do agricultural biodiversity. And that’s something formal genebanks never seem to document.
There’s a lot to unpack here with respect to agricultural diversity and evolution. Mass food manufacture is a boon for the world, but this type of industrial process should be working on ways to keep some programmed diversity in the process as well. I would have been perfectly happy for this interview to have gone on for several hours and in greater depth.
I’m sure there was audio all the way through the tour, but portions of it were cut out, likely for time editing, but I kind of wish the whole thing was there… I could probably listen to this kind of beer talk all day long. I would also appreciate a more chemistry-based technical approach to the topic as well.
The question of the definition of craft beer versus industrial beer is a very good, yet subtle one.
I’m actually curious to try a beer that’s based on legumes to see what the increased protein percentages do to the flavor. It’s also interesting to hear about the potential creation of a signature Italian style beer.
I found the article in it so interesting, there was some brief conversation around it and I thought to recommend it to my then new friend Jeremy Cherfas, whose Eat This Podcast I had just recently started to enjoy. Mostly I thought he would find it as interesting as I, though I hardly expected he’d turn it into a podcast episode. Though I’ve been plowing through back episodes in his catalog, fortunately this morning I ran out of downloaded episodes in the car so I started streaming the most recent one to find a lovely surprise: a podcast produced on a tip I made.
While he surely must have been producing the episode for some time before I started supporting the podcast on Patreon last week, I must say that having an episode made from one of my tips is the best backer thank you I’ve ever received from a crowd funded project.
Needless to say, I obviously found the subject fascinating. In part it did remind me of a section of Herve This’ book The Science of the Oven (eventually I’ll get around to posting a review with more thoughts) and some of his prior research which I was apparently reading on Christmas Day this past year. On page 118 of the text This discusses the classic French sauces of Escoffier’s students Louis Saulnier and Theodore Gringoire  and that a physical chemical analysis of them shows there to be only twenty-three kinds. He continues on:
A system that I introduced during the European Conference on Colloids and Interfaces in 2002  offers a new classification, based on the physical chemical structure of the sauce. In it, G indicates a gas, E an aqueous solution, H a fat in the liquid state, and S a solid. These “phases” can be dispersed (symbol /), mixed (symbol +), superimposed (symbol θ), included (symbol @). Thus, veal stock is a solution, which is designated E. Bound veal stock, composed of starch granules swelled by the water they have absorbed, dispersed in an aqueous solution, is thus described by the formula (E/S)/E.
This goes on to describe in a bit more detail how the scientist-cook could then create a vector space of all combinations of foods from a physical state perspective. A classification system like this could be expanded and bolted on top of the database created by Jaan Altosaar and improved to provide even more actual realistic recipes of the type discussed in the podcast. The combinatorics of the problem are incredibly large, but my guess is that the constraints on the space of possible solutions is brought down incredibly in actual practice. It’s somewhat like the huge numbers of combinations the A, C, T, and Gs in our DNA that could be imagined, yet only an incredibly much smaller subset of that larger set could be found in a living human being.
The additional byproduct of catching this episode was that it finally reminded me why I had thought the name Jaan Altosaar was so familiar to me when I read his article. It turns out I know Jaan and some of his previous work. Sometime back in 2014 I had corresponded with him regarding his fantastic science news site Useful Science which was just then starting. While I was digging up the connection I realized that my old friend Sol Golomb had also referenced Jaan to me via Mark Wilde for some papers he suggested I read.

I love that Jeremy raises the question of preparation time in discussing the Supplemental Nutrition Assistance Program (SNAP). It’s something that doesn’t seem most people would consider, but which in the modern world has become a major consideration. To some extent a lot of the growth of obesity in the U.S. is as a result of people going to restaurants and eating less healthy food out, but justifying it for the savings in time and the general convenience.
As I’m listening, I’m curious what these types of programs look like in other countries? How does the U.S. compare? Do those countries leverage the same types of research and come up with similar plans or are they drastically different? I’m thrilled that in the very last line of the episode, Jeremy indicates that he may explore this in the future.
I’ll also guiltily admit that while listening to this episode, I was snacking on M&M chocolate candies while drinking a sugary supplemented beverage. Perhaps I’ll pay my penance later by baking a fresh loaf of bread.
Interesting to think about the shifts of food stuffs between the upper and lower classes over time.
I half expected some discussion of dentition and bone studies, but this was a bit more broadly historical in scope. I always loved the studies of civilizations around 12,000 years ago at the dawn of the agricultural age and the apparently terrible ravaging effects of settling down and living off of of agriculture rather than hunting and gathering.
Knife skills and knife care are rarely spoken about in many settings and when they are, they’re usually horribly inconsistent, if not butchered. Here Jeremy interviews a real knife guru. Sadly in an audio podcast there’s only so much that can be covered without video. I could have done with another hour on the topic along with some video perhaps.
I’m now so many wonderful episodes in, that it was far past time to give something back to Jeremy for the hours of work he’s put in to give me so much entertainment, enjoyment, and even knowledge. So I just made a pledge to support him on Patreon.
If you haven’t been paying attention, Eat This Podcast is a fantastic series on food, but it it uses the “foods we eat to examine and shed light on the lives we lead, from authenticity to zoology”. Food becomes his “vehicle to explore the byways of taste, economics and trade, culture, science, history, archaeology, geography and just about anything else.”
It’s unlike much of anything I’ve seen or followed in the food space for some time. As someone who is a fan of the science of food and fantastic writers like Harold McGee, Herve This, Alton Brown, Tom Standage, Michael Pollan, Nathan Myhrvold, Maxime Bilet, Matt Gross, and Michael Ruhlman (to name only a few), Eat This Podcast is now a must listen for me.
Not only are the episodes always interesting and unique, they’re phenomenally well researched and produced. You’d think he had a massive staff and production support at the level of a news organization like NPR. By way of mentioning NPR, I wanted to highlight the thought, care, and skill he puts into not only the stunning audio quality, but into the selection of underlying photos, musical bumpers, and the links to additional resources he finds along the way.
And if my recommendation isn’t enough, then perhaps knowing that this one person effort has been nominated for the James Beard Award in both 2015 and 2016 may tip the scales?
If you haven’t listened to any of them yet, I highly recommend you take a peek at what he has to offer. You can subscribe, download, and listen to them all for free. If you’re so inclined, I hope you’ll follow my lead and make a pledge to support his work on Patreon as well.
