Ancient Europeans farmed dairy—but couldn’t digest milk 2022-07-27T04:00:00Z Scientists have long suspected that dairy consumption and the persistence of lactase rose together in human history. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z The researchers’ model found that lactase persistence was more likely to occur in ancient populations exposed to animal pathogens and famine than in those exposed to other factors examined. How Humans’ Ability to Digest Milk Evolved from Famine and Disease 2022-07-28T04:00:00Z That undercuts a myth, propagated by white supremacists, that lactase persistence and milk drinking are somehow associated with white Europeans. Humans were drinking milk before they could digest it 2021-01-27T05:00:00Z The finding only deepens the mystery of lactase persistence. Warrior skeletons reveal Bronze Age Europeans couldn’t drink milk 2020-09-03T04:00:00Z The findings support the idea that dairy farming alone wasn’t the key force behind the spread of lactase persistence, the researchers say: The selection pressure likely only grew strong when combined with sickness and starvation. Ancient Europeans farmed dairy—but couldn’t digest milk 2022-07-27T04:00:00Z When people started herding cattle and other livestock some 10,000 years ago, the theory went, those with a mutation for lactase persistence gained a new source of calories and protein. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z Yet scientists have struggled to explain the forces underlying the high prevalence of lactase persistence in Europe. How Humans’ Ability to Digest Milk Evolved from Famine and Disease 2022-07-28T04:00:00Z Many people are lactose intolerant because they lack enough of the enzyme lactase to break down lactose, the natural sugar found in milk. How much dairy is right for your diet? It depends — if you can stomach it, though, it’s a dependable nutrient source. 2020-06-01T04:00:00Z But the Tollense skeletons show that at least 6000 more years went by before the gene for lactase persistence caught on. Warrior skeletons reveal Bronze Age Europeans couldn’t drink milk 2020-09-03T04:00:00Z Now, a study combines large archaeological data sets on dairy farming with ancient DNA and finds that across Europe, people consumed dairy for millennia before lactase persistence into adulthood was widespread. Ancient Europeans farmed dairy—but couldn’t digest milk 2022-07-27T04:00:00Z Dr. Evershed and his colleagues found that Europeans were consuming milk without lactase for thousands of years, despite the misery from gas and cramping it might have caused. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z They then modelled how various factors, such as the use of dairy milk and population size, explained the rise of lactase persistence, drawing on the genomes of more than 1,700 ancient Eurasian people. How Humans’ Ability to Digest Milk Evolved from Famine and Disease 2022-07-28T04:00:00Z Taking lactase supplements, or choosing special lactose-free milk are other options. How much dairy is right for your diet? It depends — if you can stomach it, though, it’s a dependable nutrient source. 2020-06-01T04:00:00Z The firm won an Accelerator grant to develop a subcutaneous sensor to simultaneously monitor glucose, ketones, and lactase in diabetic patients. Watch out Silicon Valley: European Union gets into the venture capital game 2020-04-08T04:00:00Z The research complements previous results, such as the puzzlingly late arrival of widespread lactase persistence in Central Europe, says Christina Warinner, a molecular archaeologist at Harvard University. Ancient Europeans farmed dairy—but couldn’t digest milk 2022-07-27T04:00:00Z Mark Thomas, a geneticist at University College London, led the team’s analysis of lactase persistence. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z This mutation affects a section of DNA controlling the activity of the gene for lactase - an enzyme that breaks down lactose sugar. Earliest evidence of milk consumption 2019-09-10T04:00:00Z Babies are born with the capacity to make lactase, the enzyme needed to digest the lactose in milk, but generally lose it when they are weaned in infancy. Can the world quench China’s bottomless thirst for milk? 2019-03-29T04:00:00Z But for the majority of humans, production of the enzyme lactase plummets after weaning. White gold: the unstoppable rise of alternative milks 2019-01-29T05:00:00Z It enables the body to produce lactase, an enzyme that digests the sugar in milk, into adulthood. Machine learning spots natural selection at work in human genome 2018-10-31T04:00:00Z They looked for a mutation that kept the lactase gene switched on during adulthood. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z Genetic studies of ancient populations from across Eurasia show that lactase persistence only became common very recently, despite the consumption of milk products in the Neolithic. Earliest evidence of milk consumption 2019-09-10T04:00:00Z The best-understood example of that is what is referred to as lactase persistence. Why Race Is Not a Thing, According to Genetics 2017-10-14T04:00:00Z Pills that contain the lactase enzyme that breaks down lactose also might help. Lowering cholesterol by eating fat 2017-09-24T04:00:00Z Still, these beers have a strong following, as does Lactaid milk, which relies on the enzyme lactase to break down the lactose sugar that causes digestive problems in some people when they consume dairy. Is It Possible to Make a Less Allergenic Peanut? 2016-12-15T05:00:00Z For those 2,600 years, in other words, Europeans were consuming milk despite almost none of them being able to make lactase as adults. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z For those who are lactose intolerant, the activity of the enzyme lactase is ineffective – which means it's not able to digest and absorb the sugar found in milk and dairy products. The Lowdown on Lactose Intolerance in Babies and Children 2016-07-27T04:00:00Z It wasn’t that we became lactase persistent and then started dairy farming. Why Race Is Not a Thing, According to Genetics 2017-10-14T04:00:00Z These include intestinal inflammation; deficiency of the digestive enzyme lactase, associated with lactose intolerance; and increased intestinal permeability, often called "leaky gut." Stomach Troubles Not Linked to Autism, Study Finds 2016-03-14T04:00:00Z But that reasoning doesn't work for Southern Europe, the Middle East or Africa, where lactase persistence is also found. Milk digestion's 'more recent rise' - BBC News 2015-06-11T04:00:00Z The analysis delivered some surprising results: People without the lactase mutation consume about as much milk as people who carry it. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z Children who are lactose intolerant don't produce enough lactase – a natural enzyme that digests, or breaks down, lactose. The Lowdown on Lactose Intolerance in Babies and Children 2016-07-27T04:00:00Z The lucky third—those with “lactase persistence”—continue to produce it into adulthood. No use crying 2015-03-26T04:00:00Z The ability to consume milk, for example, is due to the “lactase persistence” variant of a gene which emerged around 7500 years ago among early Europeans. Our Taste for Alcohol Goes Back Millions of Years 2015-02-03T05:00:00Z "I suspect that only more ancient DNA data will enable us to pin down why lactase persistence spread so quickly." Milk digestion's 'more recent rise' - BBC News 2015-06-11T04:00:00Z Together, these parallel lines of evidence suggest that early Europeans made milk a part of their diet, even without lactase. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z This is secondary to the normal decline in the lactase activity in the lining of the small intestine with age. The Lowdown on Lactose Intolerance in Babies and Children 2016-07-27T04:00:00Z A mutation in the lactase gene that kept it stuck in the “on” position was favored, and proliferated. Dairy Wars: Of Fats, Phobias and Froth 2014-09-08T04:00:00Z For instance, I learned that I do not produce lactase, an enzyme involved in the digestion of dairy products, and am therefore likely to be lactose intolerant. 23andMe: A Fumbling Gene In Its Corporate DNA? 2013-11-29T15:19:00Z Dr Wells thinks this precarious existence may be reflected in the spread of the lactase persistence gene, which enables people to digest milk into adulthood. European origins laid bare by DNA 2013-10-10T22:23:42Z Consuming milk without lactase became riskier later, in times of crisis, Dr. Evershed and his colleagues argued. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z That stomach lining contains lactase, the enzyme necessary for digesting lactose. Surprising Signs of Gluten Intolerance 2013-09-17T14:55:00Z A gene is responsible for generating the enzyme, lactase, needed to cleave the compound sugar in milk, lactose. Dairy Wars: Of Fats, Phobias and Froth 2014-09-08T04:00:00Z The sugar is in the form of lactose, which, in folks who aren't lactose intolerant, is cleaved into glucose and galactose by the enzyme lactase. Please Stop Asking Your Children to Finish Their Milk 2013-09-11T21:48:00Z Several thousand years later, a genetic mutation spread through Europe that gave people the ability to produce lactase — and drink milk — throughout their lives. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z Those without lactase might have been more likely to perish, while the lactase mutation might have helped others survive. Early Europeans Could Not Tolerate Milk but Drank It Anyway, Study Finds 2022-07-27T04:00:00Z In fact, apart from lactase, overt digestive enzyme deficiencies are rare, and they generally occur in malnourished, ill individuals—not in gassy but otherwise well people. Digestive Enzymes: Help or Hype? 2013-04-23T20:15:00Z The lactase gene spread rapidly in historical populations with dairy husbandry. Patients and Evolutionary History 2013-01-25T17:15:08.877Z All infant mammals make lactase, but the gene that does the job shuts off in early childhood, at the time of weaning. Is Dairy Healthy or Not? 2012-11-30T15:03:00Z Young children almost universally produce lactase and can digest the lactose in their mother's milk. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z As people age, many experience a decrease in the production of the enzyme required to digest lactose—called lactase. IBS? Could be the FODMAPs 2012-08-28T16:35:00Z In many people, the body ramps down its production of lactase in their teens and twenties. Digestive Enzymes: Help or Hype? 2013-04-23T20:15:00Z Then there is the enzyme our bodies use to digest the lactose in milk, lactase. The Hidden Truths About Calories 2012-08-27T14:15:00.170Z “The general pattern in mammals is to lose lactase expression after weaning,” explains Dallas Swallow, a geneticist at University College London. Diversity: Of beans and genes 2011-01-04T21:23:19.127Z But as they mature, most switch off the lactase gene. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z Lactose intolerance is different, and is caused by a lack of the lactase enzyme which is essential for digestion of lactose, the sugar found in milk. Experts sort out milk debate 2010-08-03T21:00:00Z The ability to digest lactose depends on an enzyme in the gut called lactase. Think you're lactose intolerant? You might be wrong 2010-05-05T21:17:00Z As a result, even if they drink milk they receive far fewer calories from doing so than do individuals who produce lactase. The Hidden Truths About Calories 2012-08-27T14:15:00.170Z For example, lactase persistence is characteristic of 89%–96 of Scandinavian and British people, is widespread among pastoralist cultures in Africa and the Middle East, but appears in only 1 of Chinese individuals. Diversity: Of beans and genes 2011-01-04T21:23:19.127Z That next step happened slowly, and it seems to have required the spread of lactase persistence. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z People of any age who aren't accustomed to consuming milk may not produce as much lactase as if they drank milk regularly, she says. Experts sort out milk debate 2010-08-03T21:00:00Z The lactose, maltose, and sucrose are changed through the activity of the lactase, maltase, and invertase into glucose. Dietetics for Nurses It is possible to take lactase to break down the milk sugars for example; sometimes aids such as hydrochloric acid, pepsin, and pancreatin help. How and When to Be Your Own Doctor Most geneticists cite lactase persistence as a leading example of recent human evolution driven by shifts in culture and diet. Diversity: Of beans and genes 2011-01-04T21:23:19.127Z But as the agricultural society expanded northwards and westwards into new territory, the advantage provided by lactase persistence had a big impact. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z In southern Europe, lactase persistence is relatively rare — less than 40% in Greece and Turkey. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z During the process of digestion, lactose is hydrolized by the lactase in the intestinal juice, yielding one molecule of glucose and one of galactose. Dietetics for Nurses But lactase persistence also took root in sunny Spain, casting vitamin D's role into doubt. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z During the most recent ice age, milk was essentially a toxin to adults because — unlike children — they could not produce the lactase enzyme required to break down lactose, the main sugar in milk. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z It is probably much like the cheese that Neolithic farmers in the region would have eaten some 8,000 years ago — long before the march of lactase persistence allowed people to drink fresh milk. Archaeology: The milk revolution 2013-07-31T17:20:20.587Z They proposed that the trait of lactase persistence, dubbed the LP allele, emerged about 7,500 years ago in the broad, fertile plains of Hungary.
