Where I come from, a bottle of dark beer a day was a standard recommendation to breastfeeding mothers. Not because of the alcohol, but because of everything else that's in it, very nutritious. These days, the recommendation has turned to non-alcoholic malt beer, a calory bomb.
And from when our children were still little, I remember that a dinner of fatty foods coupled with a 30 minute wait period and then breastfeeding would keep Teresa and Leon asleep longer before hunger would wake them for a return to the "docking station".
That beer ad therefore has more than a ring of truth in it.
And those parts in Europe with the highest red wine consumption (Southern France and Italy's wine regions) are the ones where the male population has the least cardiological issues. It comes at a price though, they are also the regions where an otherwise rather rare form of throat cancer is most prevalent.
