Known as lactase4
  • The reason why some people are unable to fully digest lactose is that they lack an enzyme known as lactase. (home-remedies-for-you.com)
  • Why this trait -- known as lactase persistence -- has evolved so quickly has been something of a mystery. (sciencedaily.com)
  • Lactaid pills work by supplying your body with the enzyme known as lactase, which immediately goes to work supporting your body's ability to digest lactose. (swansonvitamins.com)
  • In the human body, an enzyme known as lactase is in charge of breaking down lactose-a carbohydrate found in mammalian milk (including milk from cows, goats, and so on)-so it can be absorbed by the small intestine. (everlywell.com)
Small intestine13
  • Lactase is an enzyme that some people are unable to produce in their small intestine. (wikipedia.org)
  • In most of the world's population, lactase transcription is down-regulated after weaning, resulting in diminished lactase expression in the small intestine, which causes the common symptoms of adult-type hypolactasia, or lactose intolerance. (wikipedia.org)
  • The small intestine normally makes a special substance called lactase (say: LAK-tase), an enzyme that breaks lactose down into simpler sugars called glucose (say: GLOO-kose) and galactose (say: guh-LAK-tose). (kidshealth.org)
  • People with lactose intolerance do not make enough lactase in their small intestine. (kidshealth.org)
  • Lactose intolerance occurs when the small intestine does not make enough of an enzyme called lactase. (ndtv.com)
  • Sometimes the small intestine stops making lactase after a short-term illness such as the stomach flu, or as part of a lifelong disease such as cystic fibrosis. (ndtv.com)
  • The lining of the small intestine is responsible for the production of lactase. (home-remedies-for-you.com)
  • Lactose intolerance occurs when the enzyme lactase is produced by the small intestine in low quantities. (home-remedies-for-you.com)
  • Lactase is released by the cells that make up the lining of the small intestine. (home-remedies-for-you.com)
  • Secondary Lactose Intolerance The small intestine may reduce its production of lactase during illness, injury or surgery. (home-remedies-for-you.com)
  • The enzyme lactase is in the lining of the small intestine known as the intestinal villi. (gi.org)
  • This condition is due to a normal decline in the amount of the enzyme lactase present in the small intestine as we age. (gi.org)
  • People who cannot digest lactose have a shortage, or deficiency, of the enzyme called lactase, which is produced in the small intestine. (healthyreflections.com)

  • Dienekes' Anthropology Blog: Demography and selection in the spread of Lactase persistence in Europe (Gerbault et al. (blogspot.com)
  • Simply put, the frequency of the Lactase Persistence (LP) allele in most of southern Europe can be explained by demography alone, as the result of genetic drift during the Neolithic diffusion from the Near East. (blogspot.com)
  • This is more compatible with the calcium assimilation hypothesis, since lactase persistence is beneficial in low sunshine (high latitude) regions than with the gene-cultural co-evolution hypothesis, according to which pastoralists become LP because of their need to rely on animal milk. (blogspot.com)
  • Two hypotheses are usually proposed to explain the particular distribution of the lactase persistence phenotype. (blogspot.com)
  • The calcium assimilation hypothesis suggests that carriers of the lactase persistence allele(s) (LCT*P) are favoured in high-latitude regions, where sunshine is insufficient to allow accurate vitamin-D synthesis. (blogspot.com)
  • In this work, we test the validity of these two hypotheses on a large worldwide dataset of lactase persistence frequencies by using several complementary approaches. (blogspot.com)
  • We first analyse the distribution of lactase persistence in various continents in relation to geographic variation, pastoralism levels, and the genetic patterns observed for other independent polymorphisms. (blogspot.com)
  • In Europe, we show that population history played an important role in the diffusion of lactase persistence over the continent. (blogspot.com)

  • To see how much natural selection was needed to drive lactase persistence up to today's frequencies in that Iberia, Sverrisdóttir contacted her colleague Professor Mark Thomas in London. (sciencedaily.com)
  • But here's the thing," says Sverrisdóttir, "if natural selection is driving lactase persistence evolution in a place where people have no problems making vitamin D in their skin, then clearly the vitamin D and calcium explanation (known as the calcium assimilation hypothesis) isn't cutting it. (sciencedaily.com)
  • The evolution of lactase persistence is one of the best known and most dramatic examples of recent human evolution One of the ironies of working in this area is that we know it happened but we still don't fully know why" says Sverrisdóttir. (sciencedaily.com)
  • Lactase persistence is found at highest frequencies in southern Sweden and in Ireland. (sciencedaily.com)
Adulthood2
  • In the West, people take milk drinking for granted because most people of European descent are able to produce the enzyme lactase in adulthood and so digest the milk sugar lactose. (sciencedaily.com)
  • This may be due to the loss of intestinal lactase in adulthood, a condition transmitted by an autosomal recessive gene, which differs in humans according to race. (researchgate.net)
Yogurts6

  • Cow's milk gets the most attention because it seems to be the major offender, with yogurts and cheeses contributing to a far lesser extent. (intermountainhealthcare.org)
  • Cheese contains much less lactose than milk and yogurts appear to be easier to digest, possibly due to the bacteria used to make them. (express.co.uk)
  • Although breast milk or infant formula needs to be the main drink up to one year, cow's milk and other dairy products can be included in foods from when weaning starts in the forms of yogurts, custard and other milk puddings, cheese and white sauces," says paediatric dietician Judy More (www.child-nutrition.co.uk). (express.co.uk)
  • It is best to choose low-fat dairy foods such as skimmed or semi-skimmed milk, low-fat yogurts and reduced-fat cheeses. (express.co.uk)
Cheddar2

  • Problems arise if the body is unable to produce enough lactase. (express.co.uk)
  • There are a number of reasons why someone may be lactase deficient, from age and genetics, to being born without the ability to produce lactase, but the bottom line is that many Americans experience this-as many as 50 million of them. (enzymedica.com)
  • Support the lack of Digesting Dairy Products which is sometimes associated with the ingestion of lactose containing foods by people who fail to produce adequate amounts of the enzyme lactase. (healthyreflections.com)
  • This means that these animals do not produce enough of the enzyme lactase to digest large amounts of lactose, the sugar found in dairy products. (petfoodtalk.com)
  • Most mammals stop producing this enzyme when they are weaned, but humans can continue to produce lactase throughout their lives. (lafromagerie.co.uk)

(researchgate.net)
Gene3
  • This selection pressure increasing with latitude is highly compatible with the calcium assimilation hypothesis while the gene-culture coevolution hypothesis cannot be ruled out if a positively selected lactase gene was carried at the front of the expansion wave during the Neolithic transition in Europe. (blogspot.com)
  • Located on Chromosome 2, the LCT gene contains instructions for making the enzyme lactase. (23andme.com)
