Populations that have eaten a vegetarian diet over several generations have an increased risk of heart disease and cancer, according to a report published in the journal Molecular Biology and Evolution.
The report argues that communities who haven’t consumed meat for generations are more likely to carry genetic mutations that raise the likelihood of inflammatory disease and cancer.
The authors, from Cornell University in the US, believe that the mutation is the result of an adaptation which made it easier for vegetarians to absorb fatty acids from plants. They believe that the mutation, found in the FADS2 gene, causes these fatty acids to be converted into arachidonic acid.
The researchers studied the genomes of a vegetarian settlement in Pune, India. They compared them with those of a community in Kansas with a Western diet, and found a ‘significant genetic difference’ between the populations.
Tom Brenna, the study’s lead author, said: ‘Those whose ancestry derives from vegetarians are more likely to carry genetics that more rapidly metabolise plant fatty acids.
‘In such individuals, vegetable oils will be converted to the more pro-inflammatory arachidonic acid, increasing the risk for chronic inflammation that is implicated in the development of heart disease, and exacerbates cancer.
‘The mutation appeared in the human genome long ago, and has been passed down through the human family. To make the problem worse, the mutation also hinders the production of beneficial omega-3 fatty acid which is protective against heart disease. Although it may not have mattered when the mutation first developed, since the industrial revolution there has been a major shift in diets away from omega-3 — found in fish and nuts — to less healthy omega-6 fats, found in vegetable oils,’ Brenna said.
Wenn alle "gleich" sein sollen und "gleichgestellt", funktioniert das nur auf dem niedrigsten Niveau. Denn wenn 10 Leute 100m laufen und alle zur gleichen Zeit am Ziel ankommen sollen, dürfen sie alle nur so schnell laufen wie der Langsamste. Nur warum soll der sich dann noch anstrengen, wenn die "Gleichheit" ihn sowieso mit den anderen auf die oberste Stufe des Siegertreppchens stellt? Und was soll das mit der Gesellschaft machen? Kann man sich in jedem (!) sozialistischen Staat anschauen.
