Sebnoufou. You tell it like it is. I would not have the courage to be quite so blunt on this forum.
It is quite interesting when talking about health both Steve and I used the same metrics. Infant mortality and in Steve's case life expectancy.
In some ways they both encapsulate the essentials of a person's life linking health with duration. True as far as it goes but also skips over such things as quality of life and the truism that you are what you eat. My links above demonstrate there was a class divide impacting heath up to the end of WW1. Basic nutrition was understood by WW2 and
as a result all socioeconomic groups benefited. Post the 1954 end of rationing many things changed. The NHS, increasing car ownership, advances in medicine, diminishing cost of food, take aways and prepackaged meals........
    The government may have experts on nutrition, but try to have an intelligent conversation on the street about the subject and prepare to be disappointed. I would have to agree with Steve's last sentence above. We have a rising tide of obesity that has not yet had significant impact on mortality rates, but repeated studies suggest that it will, because there would seem to be a link between obesity and susceptibility to other diseases. IN 1950 most people walked, now kids no longer even walk to school(admittedly sometimes for good reason) " Just 60 years ago the average woman stood 5ft 2in tall, weighed 9st 10lb and was a size 12, with a tiny 27-inch waist.Today, according to the UK National Sizing Survey, we average a size 16, grow to around 5ft 4in, weigh around 10st 3lb, and our waists have expanded by a staggering seven inches".
As convenience rules supreme, and there is not a vast cost differential between cooking from scratch and wacking something frozen into a microwave, the outcome can hardly come as a surprise. Nutrition should be taught in schools along with basic cookery skills. It is hard to know if it is truly ignorance or idleness causes the problem.
As big government pokes it's nose into all aspects of life today perhaps a case could be made for reintroducing rationing with punitive taxes on gluttony. In an electronic world this would present no problem. Exceed your family calorie count and get hammered. I knew one far kid at secondary school out of 600 and he had a medical problem.
You have a challenge trying to find a skinny one today. Also the lobbying by these companies would terminate such a scheme immediately. Health eating could be achieved in schools if the government had the will. I recall my school dinners being nutritious but this does nor always equate with appetising.
