    Two copies of a genetic mutation make their way of absorbing sugar different from others
    .

    "Adult Greenlanders with genetic variants have lower BMI, weight, fat percentage, and cholesterol levels and are generally healthier
    .


    They have less abdominal fat and may be more likely to have six-pack abs


    Professor Albrechtsen and colleagues from the University of Copenhagen, the University of Southern Denmark and some research institutions and public institutions in Greenland analyzed the data of 6,551 adult residents of Greenland and performed it on mice.


    The experiment


    The results showed that people with this genetic variant suffer from sucrase-isomaltase deficiency, which means that they have a special way of metabolizing sugar in the intestine
    .


    Simply put, they do not absorb ordinary sugar in the blood like people without genetic mutations


    Here, intestinal bacteria convert sugar into a short-chain fatty acid called acetate.
    In previous studies, acetate has been shown to reduce appetite, promote metabolism, and strengthen the immune system
    .


    This is probably the mechanism that happened here," explains Mette K.


    Why genetic variation is common among Greenlanders

    Greenlanders have this extensive genetic variation because their eating habits have been different from those in other parts of the world for thousands of years
    .

    "This may be because Greenlanders don’t have too much sugar
    in their diet .


    In most cases, they eat the meat and fat of fish, whales, seals, and reindeer.


    He added that this makes genetic mutations happen frequently because there is no need to absorb sugar quickly in the blood
    .

    Genetic variation is difficult for children

    Although this difference has obvious benefits for the health of adult Greenlanders, it is a problem for their children
    .

    "Young carriers of this mutation experience negative consequences because they absorb different types of sugar
    .


    For them, sugar intake can cause diarrhea, abdominal pain, and bloating


    He and the research team hope that they can use the results of this new study to lay the foundation for the development of new drugs that may one day treat cardiovascular disease and obesity
    .

    "We can see that genetic mutations provide better fat balance in the blood, which leads to lower body weight and thus fewer cardiovascular diseases
    .


    If you can develop a drug that inhibits the invertase-isomaltase gene , Then in principle, we may all have the same strong health," he concluded


    Research summary:

    Mouse diet experiment

    • In addition to the health data of 6,551 Greenlanders, the researchers also supplemented their research with diet experiments in mice
      .


      They tried to investigate what happened in the gut of people with genetic mutations


    • To this end, they studied two groups of mice
      .
      One group was artificially inhibited to absorb sugar, which is similar to the genetic variation found in Greenlanders
      .
      Sugar absorption in the second group was normal
      .

    • Their results showed that when mice with inhibitory ability had free access to fat and sugar food, their weight gain was only half that of the other group of mice
      .
      This confirms the researchers' analysis of health data, that gene mutations have a series of health benefits, including weight reduction and BMI
      .
