French people are adopting the Western diet in considerable numbers with all of the fast food chains getting in there. Obesity is on the rise. I have not been there recently but I expect to see things have changed across all demographics apart from the elderly.

France cannot be used for comparison studies when it comes to diet and alcohol in the way it used to be.

In what way? There has been plenty of studies on this and the general consensus is that while there may be certain health benefits to alcohol under certain conditions, in aggregate alcohol in any amount does not have a net positive effect on overall health.

The counter argument for the J curve/French Paradox study is that their data for people who don’t drink is biased — it doesn’t distinguish between people who never drink because they don’t want to, and those who stopped due to underlying health conditions (thus making it appear as if mortality among those who don’t drink is higher).
