    Red meat molecule 'may cause health problems'

    Eating red meat introduces a potentially dangerous non-human molecule into the body tissues, new
    research has showed.

    A study found that the molecule, a sugar only found in non-human mammals, is absorbed into tissues
    such as blood vessels and secretory cells.

    Tests showed that it can generate an immune response which might induce harmful inflammation.

    The scientists have not ruled out a link with cancer and heart disease - although they acknowledge
    that at present this is speculation.

    To date, research has focused on the role of red meat saturated fats and chemical products that
    arise from cooking.

    The new study, led by scientists at the University of California in San Diego, USA, is the first to
    investigate dietary absorption of a cell-surface sugar called N-glycolylneuraminic acid (Neu5Gc).

    Humans are genetically unable to produce the molecule, which occurs naturally at high levels in
    lamb, pork and beef. Only very low or undetectable amounts of the sugar are found in fruits,
    vegetables, hen's eggs, poultry and fish.

    Laboratory studies and tests on three human volunteers - all members of the research team -
    confirmed that ingested Neu5Gc is absorbed into human tissues.

    They also demonstrated that the body may view the molecule as a non-human invader and launch an
    antibody-based immune response against it.

    Although the sugar does not occur naturally in humans, other researchers have found traces of it in
    human cancer tumours.

    Oh! Would it still be a non-human molecule if you are an aborigine cannibal eating a human leg? Or,
    is human flesh considered white meat? I mean really: Shouldn't you be more precise in your use of
    terminology?

    And, what does this have to do with iron?

    Ha, ... Hah, Ha!
