    The French are in better health than Americans with respect to heart
    attacks, and probably also ischemic stroke. I'm not sure about their score
    with respect to hemorrhagic stroke.

    In one study I've seen, the French were found to eat more fruits and veggies
    and fish and fowl than the Brits, presumably at the expense of fatty red
    meats and grains. This could very well explain their good health in
    paleodiet terms. Also, as you mentioned, their moderate but chronic
    consumption of red wine very likely helps.

    I wouldn't be so sure of that! The French likely benefit from the
    antioxidants (polyphenols) in red wine but this may be only part of the
    story. Surprisingly, moderate alcohol consumption was almost certainly a
    staple of the paleolithic diet. It's extremely likely that hominids have
    been eating fermented fruits for millions of years. Also organisms in our
    gut are producing alcohol constantly. In fact we've evolved an enzyme for
    the specific purpose of metabolizing alcohol (called alcohol dehydrogenase,
    if memory serves). The evidence suggests very strongly that the human genome
    expects modest amounts of alcohol.
