No. Heavy manual labour in the industry died. People were eating this same junk in the 80s and 90s to a certain degree granted it was mainly fish and chip shops. They burnt it off in the steel mills and such.
I don't agree with that at all,
Heavy manual jobs were never really any good for keeping fit, they made you a bit stronger than the average person, but on the whole - exercise isn't really all it's cracked up to be for losing weight, - if you've looked at the latest research, it starts and ends in the kitchen. (I'm a part time aerobics instructor so I regularly deal with the super-fit and people looking to lose weight)
Also, in the 80s and 90s the contents of your average supermarket were drastically different to today, there was far far less sugar for a start, there were also hardly any takeaway chains compared to today, let alone online delivery - (justeat, deliveroo, etc) in the 80's especially, there were far fewer "carb heavy" foods than they are today, like pizza.
Ive never filled a supermarket with anything.
Nor have i ever been forced to buy or consume anything from a supermarket.
It is thier own fault they ended up fat.
You can say "it's their own fault" to a certain extent, but not the whole extent, not unless you're very naive and simple.
In 2015 the percentage of overweight adults in the uk was 62.9% and rising, at what point do do we start to wonder that it *might* not be useful to simply blame them all and shrug it off? 70%? 80%? 90%? do we get to the same point as America, where involvement of major fast food companies directly buying into and influencing government policy is normal? Is it still "all their own stupid fault" when guidance written by WHO on halving the amounts of sugar is thrown out and ignored?
It seems clear to me, that this problem runs far, far deeper than people simply making bad decisions about what food they buy, when 1/2 of the food for sale in your local shops is loaded with excess sugar at harmful levels, I don't think it's fair to dump the blame for all of this, at the doors of the consumer.
