I was a bit surprised about the education bit, as I was expecting the UK to score much better on that. But I was not so surprised at the rest.
What I apreciate from my own personal experience when I'm out and about with my son is that, whereas in other countries children are celebrated -in terms of everyone being nice, warm and even fussy around them, which I think makes them feel very special-, here he is invisible, even old people was afraid of cooing at him as a baby, I guess at the fear of being misinterpreted by the mother. And he is just an object to be frowned upon if he is with us outside after 7:30. Although, the positive point of it, is that grown ups get to have a well deserved adult time.
In terms of communication between the family, it is my belief that it takes place more efficiently when all the family sits around a table for eating. No distractions (apart from the food), it's a daily time to spend together regardless of the weather and economical situation.
This time may be dirupted by work commitments but at the end of the day most parents are fortunate to leave work before 6, and yet, lots of children don't eat regularly with their parents. Eating in front of the television, or putting the children to bed before the adults sit to eat is handy and relaxing (We do it some days, I agree) but it doesn't allow for the family to communicate about what has been going on during the day. My main cultural shock had been to know that a small, but significant, number of people don't even have a dinning/breakfast table to eat together.
But in terms of food, I think that is unfair to evaluate the UK using the same parameters as for the Med countries. Blame it on the weather, but historically speaking, Britain may not have the same nutritional habits as the mediterranean countries for the simple reason that up until recently many fruits and vegetables were not being grown around here or were simply not available, therefore they didn't belong to the tipical day to day diet. Things are changing, and changing fast but having fresh fruit and vegetables a la Gillian is, frankly, still VERY expensive, so many families may only afford to go for pre processed food. So it is very easy to say we don't eat as well as the italians but the italians don't have to pay such high prices for their food.
