Knock on the hands for those English parents who have an obese child, and who have had a letter delivered by the principal of the child’s school in which they are advised to put him on a diet, basically. How? Avoiding giving the child industrial snacks for snacks, junk food, junk food to eat during school hours. Better would be a sandwich with natural ingredients, it says in the letter or even fruit and vegetables. Public opinion was divided on this initiative.

On the one hand, in fact, in Great Britain childhood obesity is in an alarming growth, therefore every initiative is something: even in Italy childhood obesity is among the highest in Europe  , reaching twenty percent of obese children, therefore one in five, without considering those who are overweight. In Campania, one in two children has weight problems. What should we do? Why do we do almost nothing?
On the other hand, the parents perceived this as an interference: the school should take care of the education of the children, not their weight problems. In addition, the issue is also economic, which is never discussed enough: snacks and many packaged products are in fact hyper-cheap. At the supermarket you can find snacks for six for the price of one euro, or biscuits. With a few cents you can always buy yourself some crap from the machine. A fruit juice can cost as much as thirty cents, a green juice exceeds ten euros. 

We can speak profusely of the goodness of eggs from organic farming, but the point is that those who don’t make it to the end of the month must eat: and obesity is often linked to groups of the indigent population, especially in the West. It is no coincidence that wherever you are you can have a full meal at Mc Donald’s for a few euros and a hambuger for just one euro. 
So rather than solving it with lecture to parents, schools but primarily governments should promote nutritional programs in schools, with canteens as God commands; and I think that the same schools can decide or not what to put in the vending machines, establishing different contracts with the companies that deal with them, for example.
In short: childhood obesity is a sacrosanct problem, but in my opinion it should not be dumped on the shoulders of parents, full stop.
