Ancient humans drank milk even when lactose intolerant

I’ve long been mystified by why the Chinese government promotes milk consumption so strongly and why Chinese grocery stores, like this one I saw in Beijing, devote so much space to selling dairy foods, when they can’t comfortably digest the lactose in milk.

Asian and many other populations stop making the enzyme that digests lactose sugar a few years after early childhood and become intolerant to that sugar.  So why continue to consume dairy products?

Nature has a new article shedding some light on the question of whether lactose tolerance is inducible.  Do people who eat dairy products develop tolerance?  Or is it just that people who can eat dairy do eat dairy?

  • Dairying, diseases and the evolution of lactase persistence in EuropeHere we provide detailed distributions of milk exploitation across Europe over the past 9,000 years using around 7,000 pottery fat residues from more than 550 archaeological sites. European milk use was widespread from the Neolithic period onwards but varied spatially and temporally in intensity…In the UK Biobank cohort of 500,000 contemporary Europeans, LP [lactose persistence] genotype was only weakly associated with milk consumption and did not show consistent associations with improved fitness or health indicators.

The authors propose:

  • Lactose intolerant people drank milk when it became available.
  • Under conditions of famine or exposure to diarrhea-inducing pathogens, consuming lactose made the diarrhea worse.
  • This acted as a selection pressure for continuing production of the lactase enzyme.
  • But population fluctuations, settlement density and wild animal exploitation are better explanations for the persistence of the enzyme than the extent of milk usage.

An editorial expands on these ideas.

  • The mystery of early milk consumption in Europe:  The authors propose instead two alternative evolutionary avenues to explain the rise in prevalence of alleles for LP, related to [1] shortages of food or [2] the consequences of increased exposure to disease-causing agents (in relation to animals, crops or from living in close proximity to others without proper sanitation). In either situation, or in a combination of both scenarios, an individual’s ability to diversify their diet away from crops and meat, which might be affected by shortages, and to take advantage of the hydration and calories afforded by dairy products, could be extremely beneficial.

Or you can listen to a podcast:

  • How humans adapted to digest lactose — after thousands of years of milk drinking:  Humans have been drinking milk for thousands of years, but it seems that they were doing so long before the ability to digest it became prevalent. Then, around 2,000 years ago, this ability became common in Europe, presenting a mystery to researchers — why then? Now, by analysing health data, ancient DNA and fats residues from thousands of ancient pots, scientists have worked out what caused this trait to suddenly spread throughout Europe.

And take a look at a Nature article from 2019:

  • Early Europeans bottle-fed babies with animal milk: Writing in Nature, Dunne et al. describe an analysis of spouted vessels found in ancient graves of infants in Germany that indicates that these artefacts contained animal milk. This evidence suggests that such vessels were used to feed animal milk to children, providing crucial insight into the diet of developing infants in prehistoric human populations.

The dairy industry says a little lactose is harmless to people who are lactose intolerant, and milk’s nutritional benefits outweigh its risks.  Early Europeans—and today’s Chinese—must think so too.

And sorry, but I can’t resist:

Q.  Why do cows have hooves?

A.  Because they lactose.

Weekend reading: Bittman on food history

Mark Bittman.  Animal, Vegetable, Junk: A History of Food, from Sustainable to Suicidal.  Houghton Mifflin Harcourt, 2021.

This book comes with more than three pages of blurbs, starting with Al Gore and Leah Penniman and ending with José Andrés and Bryant Terry, so many and so glittery that I’m feeling a little left out that I wasn’t asked to do one.

I would have.  It’s a good book.  Bittman read a lot, is generous in citing sources (mine among them), and has done a thorough synthesis of the key events that transformed our food system from one that was healthy and sustainable (if hard on farmers) to today’s unsustainably industrialized system that is mainly set up to feed animals and fuel cars, and to encourage us to consume ultra-processed diets.   We pay the externalized costs of this system in overweight and chronic diseases that increase our vulnerability to COVID-19 and in environmental degradation and climate change.

Here are a few excerpts:

And while Deere & Co. [the tractor company] showed good will toward struggling farmers, its success in financially bonding those farmers virtually ensured that creditors remained profitable in the long run.  It’s also among the chief reasons why industrial agriculture is so difficult to change today.  Today, the company’s margins are almost four times as great from providing credit as they are from sales…Its 2019 profits were eleven billion dollars, a bit more than ten percent of the comb8ined profits of all two million-plus farms in the United States that same year [pp. 107-108]

In fact, the worse you were treated by American policy in the eighteenth and nineteenth centuries, the worse you were treated in the twentieth.  For example, the Social Security Act of 1935 and the Fair Labor Standards (sic!) Act of 1938 both excluded agricultural and domestic, thanks to influential southern Democrats who refused to protect the Black people working in those sectors.  This meant that the New Deal disproportionately excluded people of color from the most vital government protections….[p. 120].

You will hear, “The food system is broken.”  But the truth is that it works almost perfectly for Big Food.  It also works well enough for about a third of the world’s people, who have the money to demand and have at a moment’s notice virtually any food in the world.  But it doesn’t work well enough to nourish most of humanity, and it doesn’t work well enough to husband our resources so that it can endure,  Indeed the system has created a public health crisis (one whose effects have, in turn, exacerbated the deadly effects of COVID-19), and, perhaps even more crucially, it’s a chief contributor to the foremost threat to our species: the climate crisis.  The way we produce food threatens everyone, even the wealthiest and cleverest [p. 243].

Food and Coronavirus: the good news (!)

In this week’s updates of items related to food and Coronavirus, let’s start with the good news (yes, there is some).

I.  Free meals for New Yorkers

The New York City Department of Education has announced that it will make three free meals available every day for any New Yorker, at more than 400 locations.

  • No one will be turned away at any time
  • All adults and children can pick up three meals at one time
  • Vegetarian and halal options available at all sites
  • No registration or ID required

What, you might wonder, is in these meals?

This is no time to criticize, and I won’t.

This is a monumental undertaking and city officials deserve much praise for making what look like typical school meals available to everyone.

Much praise also to the school food service and other personnel who are preparing these meals.

II.  Recognition that the lowest-paid workers are essential

The economy and society run on the work of farmworkers,  many of them immigrants and undocumented, health care employees, restaurant delivery and food service personnel, and so many others involved in our food system.  The indispensible value of their work has suddenly become visible.   That’s a good first step, but not enough, of course.

III.  An opportunity to document history

A crisis of this magnitude calls for analysis.  It’s hard to do that when you are right in the middle of it, but the Association of Public Historians of New York State has issued a call for documentation and offers suggestions about what to write and collect right now.  We can all do this and lay the groundwork for future historical analysis.  I’m interested in the food and food politics aspects that I’ve been posting about on this site.  All suggestions welcome.

IV.  A return to home gardening and cooking

Salon’s recent article about renewed interest in gardening, canning, and baking focuses attention on how difficult it has become to get seeds and find flour, yeast, and eggs in supermarkets.   My local CSA baker (Wide Awake in Ithaca) is offering sour dough starter, flour, recipes, and instructions along with weekly loaves.  It’s still too cold to plant anything up here in the Finger Lakes, but the robins are back, the forsythia is in bloom, and it will soon be time to start the peas.

Weekend reading: History and Ethics of Jewish Food

Aaron S. Gross, Jody Myers, and Jordan D. Rosenblum.  Feasting and Fasting: The History and Ethics of Jewish Food.  New York University Press, 2020. 

This book comes with heavy-duty endorsements: a Foreword by Hasia Diner, and an Afterword by Jonathan Safran Foer.

I was interested to read it and did a blurb for it.

Feasting and Fasting is a fascinating account of the history of Jewish food, within and outside of dietary laws.   The authors engage in Talmudic debates about how specific foods and diets as a whole do or do not define Jewish identity.  Crisco is for Jews?  Peanut oil caused such debates?  Who knew.  This book is a great read.

What to quote?  So many choices.  Here’s a snippet from Jordan Rosenblum’s chapter on Jews and garlic:

After the Exodus from Egypt, when the Israelites wandered in the desert, they grew tired of eating only manna.  Comparing the varied diet that they ate as slaves in Egypt to the unvaried diet that they now enjoyed as free women and men, a few troublemakers complained: “The riffraff in their midst felt a gluttonous craving; and then the Israelites wept and said, “If only we had meat to eat!  We remember the fish that we used to eat free in Egypt, the cucumbers, the melons, the leeks, the onions, and the garlic.”

This, as it turns out, is the only mention of garlic in the Hebrew Bible.  In this chapter,

we shall briefly explore the historical association between Jews and garlic that develops over the next three millennia.  In doing so, we shall see how garlic eventually functions both internally (by Jews) and externally (by non-Jews) as a symbol that represents Self and Other—or, in the terminology favored in anthropology and food studies, how garlic operates as a metanym for Jews.

Weekend reading: history of American cuisine

Paul Freedman.  American Cuisine: And How it Got that Way.  Liveright Publishing, 2019.

Paul Freedman is an historian at Yale who in recent years has taken on food history.  His previous book, Ten Restaurants that Changed America, was on my weekend reading list in 2016.

This one covers the history of cuisine in America, addressing basic questions such as “is there such a thing as American cuisine?,” “What happened to it?,” and “What is likely to happen to it?”

The chapters cover such things as culinary nostalgia, community cookbooks, industrial food, ethnic restaurants, and the food revolution.  My favorite chapter title: “Have your cake, choose from our fifteen fabulous flavors, and eat it too.”

It’s a good read.  Here is a sample from page 367:

Americans have been enthusiastic consumers of modern products.  It is not just that historically the United States was technologically precocious or that its citizens value convenience, although these are true.  The key factor is a peculiar attitude toward food.  Americans have attempted to apply ideas about health and efficiency to diet.  Obsessed with technological progress, anxious about time-saving, and worried about physical well-being, Americans for well over a hundred years have embraced scientific nutrition, industrial food, and convenience.  They have been willing to sacrifice tradition and regional variation in favor of standard brands and their array of flavor and style.  Infatuation with science, convenience, and variety require giving up the natural taste of food in favor of texture, color, multiplicity, and simplicity of preparation.  Quick, easy, and healthful have been more important than flavor.

This is also a beautiful book, printed on high-quality paper, in an attractive easy-to-read font, and lavishly illustrated with menus, recipes, and pictures of advertisements, book covers, places, and people, many of them in color.

Reading it made me want to re-read Laura Shapiro’s Perfection Salad and Something From the Oven, both cited by Freedman in his chapter titled “women and food in the twentieth century.”

Annals of history: medical advice about sugar, 1918

The JAMA issue of May 1 reprints an article first published 100 years ago.  If I hadn’t seen the original date, I would have thought it had just been published for the first time.
The 1918 article is called “Sugar in War Time.”
It was published originally on April 6 that year.  JAMA. 1918;70(14):1003.
It begins:

During recent months, many physicians have been asked regarding the possible effects of the various newly imposed or proposed dietary restrictions or innovations on the health of the individual. … Among other plans for conservation, a reduction in the use of sugar has been urgently requested and, indeed, made inevitable at times when local shortage has curtailed the available supply so that the customary quota is not forthcoming. ..The most pertinent information is that respecting the actual use of sugar in the United States in recent years. The amount consumed in 1917 was approximately 9,100,000,000 pounds, or 88.3 pounds per capita. In 1916 it amounted to 8,300,000,000, or 84.7 pounds per capita. It is thus apparent that if these statistics are correct there has been some increase in the consumption of sugar.

Eighty-eight pounds of sugar per capita used each year represent about 110 gm. (nearly 4 ounces) per day for every man, woman and child in this country. Expressed in terms of food fuel units this is equivalent to 440 calories, a not inconsiderable portion of the daily energy needs of an adult man. The sugar of the daily diet consumed in the measure indicated by the government statistics would furnish one seventh of the food fuel where 3,000 calories are required, and even a larger proportion where the daily energy requirement is put on a lower basis. Four ounces of sugar, as the accusation now stands, is the calorific equivalent of two thirds of a quart of good milk or of eight slices of bread approximating one third of a pound.

When it is recalled that this great per capita consumption of sugar is largely a phenomenon of recent years and the result of the development of an industry whereby the price of the product has been lowered, the necessity for the inclusion of this carbohydrate up to one seventh or even one fifth of the daily energy requirement in the diet will obviously be questioned.

The article concludes with this statement:

Sugar is well utilized in the human organism; from the standpoint of cost its food value is very high, and its popularity need not be debated. But there is no consideration of nutrition that seriously demands so large an inclusion of sugar in the diet or forbids considerable reduction in its use, especially when the best interests of the civilized world demand it.

Three books about eating: 3. A Short History

This is the third book about eating I’ve been posting about.  The first two were here and here.

Graham Dukes & Elisabet Helsing.  A Short History of Eating.  The London Press, 2016.

Dukes and Helsing, married couple, English and Norwegian respectively, and friends of long standing, have produced a light-hearted, entertainingly illustrated romp through the history of the human diet, from breast milk (on which Helsing is expert) to bubble gum, based on their research into a wide range of sources, literary as well as anthropological.   The authors quote poems in appropriate places:

When mighty Roast Beef was the Englishman’s food,

It ennobled our brains and enriched our blood.

Our soldiers were brave and our courtiers were good

Oh! the Roast Beef of old England.

The illustrations display cartoons, ads, portraits, and botanicals.

Here is an excerpt to give you the flavor…

Marie Antoinette, the last Queen of France before the Revolution, is often cited—almost certainly wrongly—as having suggested that since during a famine the starving population lacked bread they should eat cake instead…But if Marie Antoinette truly did propose that the populace eat cake, what sort of cake, familiar in her royal circle, might that have been?  Modern reference sources define a brioche today as a light yeast bread with butter and eggs…A better clue…may be that provided by that infamous rascal of the day, the Marquis de Sade.  In July 1783, from his prison cell in Vincennes…he wrote a letter to his patient wife imploring her to send him: “…four dozen meringues; two dozen sponge cakes (large): four dozen chocolate pastille candies with vanilla….”

Holiday weekend idea: visit a food exhibit!

If you happen to be in Washington DC, take a look at FOOD: Transforming the American Table 1950–2000 at the Smithsonian National Museum of American History.

 

Julia Child’s kitchen is the featured exhibit, but the history of the industrialization of the U.S. food supply is well worth a look.

I especially like quirky collections of food objects.  Here’s one from the exhibit:

 

If you are in New York City, you can see Our Global Kitchen: Food, Nature, Culture at the American Museum of Natural History and check out the New York Times review so you know what to look for.

Also in New York is Lunch Hour at the New York Public Library.  If you can’t get there, the library has an online version of the exhibition.

If you happen to be in Switzerland and anywhere near Lake Geneva, Nestlé’s Alimentarium in Vevey has a special display of quirky collections: sardine cans, sugar cubes, and fruit wrappers, for example.  You can find it easily from its fork stuck into Lake Geneva.

Food exhibits seem to be the current Big Thing.  I’m trying to take advantage of them while they are around.  You too?
