Meet the Pigs Raised to Grow Kidneys and Hearts for Humans

“Biosecurity gets even tighter just a few miles away in Christiansburg, Virginia, where a new herd is being raised – pigs expected to supply organs for formal studies of animal-to-human transplantation as soon as next year.

This massive first-of-its-kind building bears no resemblance to a farm. It’s more like a pharmaceutical plant. And part of it is closed to all but certain carefully chosen employees who take a timed shower, don company-provided clothes and shoes, and then enter an enclave where piglets are growing up.

Behind that protective barrier are some of the world’s cleanest pigs. They breathe air and drink water that’s better filtered against contaminants than what’s required for people. Even their feed gets disinfected – all to prevent them from picking up any possible infections that might ultimately harm a transplant recipient.”

Chipotle’s New Guac Robots Can Peel Avocados in 26 Seconds

“Chipotle Mexican Grill Inc.’s robots that expedite avocado mashing and burrito bowl assembly are ready to serve real-life customers.

The chain said Monday that it’s piloting the two machines in restaurants for the first time after they passed tests in a lab. For now, two California locations are each getting a robot, and the company will see how workers and guests respond before they’re installed elsewhere.

Chipotle’s move into robotics highlights an industrywide-push to make restaurants more efficient. The robots take time-consuming or undesirable tasks off workers’ plates, according to Chipotle, meaning employees can focus on prepping other food items or helping guests. Such technology can also allow restaurants to serve a higher number of diners per hour without necessarily having to hire more staff, boosting profit.

Known as Autocado, the guac prep robot can cut, core and peel avocados in 26 seconds on average. The newest version adjusts itself automatically to whatever size the fruit comes in.”

India’s Average Household Food Spending Falls Dramatically

“According to the paper, the share of total household expenditure on food has declined substantially in rural and urban areas across all states and UTs.

‘It is the first time in modern India (post-independence) that average household spending on food is less than half the overall monthly spending of households and is a marker of significant progress,’ it said.

The paper is a comprehensive analysis of the Household Consumption Expenditure Survey 2022/23 and comparison with 2011/12.

‘Overall, there has been a significant increase in households’ average monthly per capita expenditure across rural and urban India across all states and UTs,’ the paper said, adding that the magnitude of the rise is substantial but varies across states and regions.”

Grim Old Days: Tom Standage’s Edible History of Humanity

So many of history's twists and turns have been guided by what people ate.

Summary: Tom Standage’s book explores how history’s major events and periods are reflected in the history of food, from the agricultural revolution to the spice trade of globalization. The book reveals the harsh realities of pre-industrial food production and the deadly consequences of misguided beliefs about food. It recounts how past societies waged wars and committed atrocities in the name of different foods, and how food has had profound historical influence over major events.


Tom Standage’s An Edible History of Humanity traces how food impacted major world events in different eras, from the agricultural revolution to the spice trade’s role in early globalization. The book covers the industrial and post-industrial eras with harrowing descriptions of the horrific famines wrought by communism’s price controls and collectivization of agriculture. Its insights into the pre-industrial age are also noteworthy.

Standage reminds the reader that food is a product of innovation and progress, saying that “a cultivated field of maize, or any other crop, is as man-made as a microchip” and that the barely edible wild ancestors of today’s foods were nothing like their modern counterparts. The book also reveals that many foods of the past looked less appetizing and tasted worse. Consider the carrot. “Carrots were originally white and purple, and the sweeter orange variety was created by Dutch horticulturalists in the sixteenth century as a tribute to William I, Prince of Orange.” And that is not the only royal anecdote in the book. In the late 17th century, pineapples were known as “the fruit of kings” in Europe because they were so rare; King Charles II of England even posed for a painting with a pineapple and held a feast in which he “cut the fruit up himself and offered pieces of it from his own plate. This might sound like a gesture of humility, but was really a demonstration of his power: only a king could offer his guests pineapple.”

An Edible History also reminds the reader that poverty was the default throughout much of history, quoting a Mesopotamian proverb from around 2,000 BC that notes, “Wealth is hard to come by, but poverty is always at hand.” In ancient Uruk, according to Standage, “80 percent of the population were farmers.” In nonindustrialized corners of the modern world, not much has changed on that front. “In poor countries such as Rwanda, the proportion of the population involved in agriculture is still more than 80 percent—as it was in Uruk 5,500 years ago.”

The vast majority of people in pre-industrial societies the world over labored on farms, and the backbreaking work took a heavy toll on their bodies. Archeology reveals that historically in agricultural societies, “female skeletons often display evidence of arthritic joints and deformities of the toes, knees, and lower back, all of which are associated with the daily use of a saddle kern to grind grain.”

The book describes how difficult life was for agricultural workers, once the greater part of humanity. Many people viewed the ceaseless agricultural labor that defined their lives as a form of divine punishment: Standage quotes a verse in the biblical Book of Genesis that reads, “Cursed is the ground because of you; through painful toil you will eat of it all the days of your life.” In some cultures, the painful struggle to produce food from the earth was likened to fighting a war. “For the Incas, agriculture was closely linked to warfare: The earth was defeated, as if in battle, by the plow. So the harvest ceremony was carried out by young noblemen as part of their initiation as warriors, and they sang a haylli [a military victory chant] as they harvested the maize to celebrate their victory over the earth.”

Sometimes, local beliefs connected to food could prove lethal. The Aztecs thought the “Earth Mother was nourished by human blood . . . and the crops would only grow if she was given enough of it” in the form of innumerable human sacrifices. “Sacrificial victims were referred to as ‘tortillas for the gods.’” The Incas also practiced human sacrifice. “After subjugating a new region, the Incas sacrificed its most beautiful people.”

Other bizarre beliefs related to food are detailed in the book. “Herodotus, the Greek writer of the fifth century B.C. known as the ‘father of history,’ explained that gathering cassia, a form of cinnamon, involved donning a full-body suit made from the hides of oxen, covering everything but the eyes. Only then would the wearer be protected from the ‘winged creatures like bats [which] have to be kept from attacking the men’s eyes when they are cutting the cassia.’” Theophrastus, another ancient Greek philosopher, believed cinnamon “was guarded by deadly snakes” and that “the only safe way to collect it was . . . to leave a third of the harvest behind as a gift to the sun, which would cause the offering to burst into flames.’” The Roman writer Tacitus worried about “spendthrift table luxuries,” such as spices now considered unremarkable. The book examines how the acquisition of what are today ordinary spices that can be purchased for a few dollars at any grocery store once inspired wars, including wars of conquest and destructive battles over trading rights. “After the year 1500 there was no pepper to be had at Calicut that was not dyed red with blood,” the author quotes Voltaire as quipping in 1756.

The book describes how in the quest for spices, often “violence was used arbitrarily and unsparingly.” For example, when the Portuguese explorer Vasco Da Gama arrived in India, he “arbitrarily burned and bombarded towns on the coast in order to force key ports to [trade spices to Portugal rather than rival Muslim merchants] and his men also sank and looted Muslim and local vessels, on one occasion using prisoners for crossbow practice; the hands, noses, and ears of the remaining prisoners were cut off and sent ashore.” This violence was over pepper, something that is now inexpensive and thoroughly unremarkable. The quest to attain nutmeg, meanwhile, led the Dutch East India Company, or Vereenigde Oostindische Compagnie (VOC), to commit human rights abuses in the Banda Islands: “Villages were burned down and the inhabitants were killed, chased off, or sold into slavery. The village chiefs were tortured and then beheaded by the VOC’s samurai mercenaries, brought in from Japan.” Again, that was over nutmeg. As the book notes: “Today most people walk past the spices in the supermarket, arrayed on shelves in small glass bottles, without a second thought.” It can be hard to imagine, but people once killed and died to obtain the likes of pepper and nutmeg.

An Edible History’s discussion of the spice trade also makes vivid how poor the state of geographic knowledge was in the past. In the 1420s, Portugal’s Prince Henry the Navigator sought in vain to “make contact with Prestor John, the legendary Christin ruler of a kingdom thought to be somewhere in Africa or the Indies.” In the 1480s, when Christopher Columbus tried to convince the Portuguese crown to fund his voyage, he was turned down in part because his calculations relied on the writings of Marco Polo, and Polo’s “book describing his travels in the East was widely regarded at the time as a work of fiction.” In fact, it wasn’t until the 19th century that scholars began to accept Polo’s travelog as a genuine historical account. When Columbus finally did make his voyage in 1492, he spread further confusion, believing he had visited Asia rather than a continent unknown to Europeans. And that was not all. “He claimed to have found the footprints of griffins.” “In the 1540s [the] conquistador, Gonzalo Pizarro, scoured the Amazon jungle in a doomed search for the legendary city of El Dorado and the ‘país de la canela,’ or cinnamon country. It was not until the seventeenth century that the search for Old World spices in the Americas was finally abandoned.”

The book also details the strange dietary advice of the past, such as dietary guidelines meant to ward off the devastating bubonic plague: “There are accounts of people being sealed into their houses to prevent the plague from spreading, and of people abandoning their families to avoid infection. Medical men proposed all sorts of strange measures that would, they said, minimize the risk of infection, advising fat people not to sit in the sunshine, for example, and issuing a series of baffling dietary pronouncements. Doctors in Paris advised people to avoid vegetables, whether pickled or fresh; to avoid fruit, unless consumed with wine; and to refrain from eating poultry, duck, and meat from young pigs. ‘Olive oil,’ they warned, ‘is fatal.’” What, then, was a person properly worried about the plague to eat? “The French doctors recommended drinking broth seasoned with pepper, ginger, and cloves. The plague was thought to be caused by corrupted air, so people were advised to burn scented woods and sprinkle rosewater in their homes, and other aromatics when going out. . . . This helped to conceal the smell of the dead and dying, as well as supposedly purifying the air. John of Escenden, a fellow at Oxford University, was certain that a combination of powdered cinnamon, aloes, myrrh, saffron, mace, and cloves had enabled him to survive even as those around him succumbed to the plague.”

Superstitions initially prevented Europeans from eating potatoes when that vegetable arrived on their continent: “Potatoes resembled a leper’s gnarled hands, and the idea that they caused leprosy became widespread. According to the second edition of John Gerard’s Herball, published in 1633, ‘the Burgundians are forbidden to make use of these tubers, because they are assured that eating them caused leprosy.’ . . . Potatoes became associated with witchcraft and devil worship.” In fact, even in the 1770s, “potatoes were still widely believed to be poisonous and to cause disease.”

The Effect of Inflation on US Food Prices: 2019–2024

The recent inflationary period has eroded some of the gains made by blue-collar workers since 1919.

Summary: The long-term trend from 1919 to 2024 shows significant improvements in food abundance, with time prices for a basket of 42 food items falling dramatically. Unfortunately, the recent inflationary period has eroded a small portion of those gains.


Now that the US inflation rate seems to be heading toward the more usual 2 percent per year, it is perhaps the right time to look at the cumulative effect of the pandemic and the government’s fiscal and monetary responses to it on food prices. To provide the proper perspective on the evolution of food prices in the United States, we need to distinguish between nominal prices and time prices and long-term and short-term trends.

People often think that food prices are much higher than they really are. That’s because something can become more affordable even as its price rises. Our wages, which reflect workers’ increasing productivity, tend to grow faster than prices. So what matters is a change in price relative to a change in hourly wage, and time price (i.e., the nominal price divided by the nominal hourly wage) tells us how long we must work to earn enough money to buy something.

In our book Superabundance, Gale L. Pooley and I looked at the US food prices from the perspective of an average US blue-collar worker between 1919 and 2019. To be specific, we obtained 1919 nominal food prices from the Bureau of Labor Statistics and compared them to nominal prices as we found them on the Walmart website in 2019. We thought that a century of data would provide a good indication of rising living standards in America. We were not disappointed.

We found that that total time price of our basket of 42 food items fell from 27.26 hours of work in 1919 to 3.85 hours in 2019. For the same amount of work that allowed a blue-collar worker to purchase one basket of the 42 commodities in 1919, he or she could buy 11.73 baskets in 2019. Food abundance rose at a compound rate of 2.49 percent per year. At that rate, blue-collar workers saw their purchasing power double every 28 years.

That’s a lot of progress!

Recently, we have updated our data to 2024. This time, we compared the Bureau of Labor Statistics prices from 1919 to Walmart prices in Cincinnati—a city with the median cost of living in the United States. The good news is that the recent bout of higher-than-usual inflation (2021–2024) came nowhere close to expunging the gains made since 1919. Compared to our ancestors just over a century ago, today’s Americans enjoy a much greater abundance of food. On the downside, food is clearly less abundant than it was in 2019.

We found that the total time price of our basket of 42 food items fell from 27.26 hours of work in 1919 to 4.45 hours in 2024. For the same amount of work that allowed a blue-collar worker to purchase one basket of the 42 commodities in 1919, he or she could buy 9.45 baskets in 2024. Food abundance rose at a compound rate of 2.27 percent per year. At that rate, blue-collar workers saw their purchasing power double every 30.86 years.

In other words, because of inflation between 2019 and 2024, US blue-collar workers need to work an extra 36 minutes (3 hours 51 minutes versus 4 hours 27 minutes) to buy the same kind and quantity of foods that they bought in 2019. This 16 percent increase in time price of our basket of 42 food items is a sad reflection on the US government’s fiscal and monetary incontinence and the draconian policies implemented during the COVID-19 pandemic. As ever, inflation has raised prices for those Americans who could least afford it.
