As you may have surmised I've been doing some reminiscing, and looking back at what changed in our diets and when.
Processed foods started back in the 19th century but were originally made out of Real Food. I suspect this changed around the sixties, and from then on the change accelerated.
Both my gran and my mother used to bake cakes and buns etc. which were high carb, and in retrospect affected me badly, but not so many other people.
I suspect this was because they used healthy saturated and similar natural fats to cook with - butter, lard, suet and beef dripping.
Mother had a tiny bottle of olive oil which she would sprinkle on salads. Other than that we had no "vegetable oils" until probably the sixties or seventies.
I can recall "vegetable shortening" and Trex, which were probably trans fats, and if I dug through some boxes in the garage I'd probably find the promotional (free) cookbooks that came with them.
Margarine probably came in during the War, they used it occasionally, not out of preference.
I think it was about the seventies when "vegetable oil" and branded and widely advertised margarines entered the scene, along with the first phase of "low fat" dietary disaster.
There's some pretty good history from
Gary Taubes
and again
and Mary Enig and Sally Fallon
from an American perspective, we probably lagged the US by a bit but not by much.
Purely temporally this looks to have a major correlation to the "eepidemics" of obesity, diabetes and a whole bunch of other diseases which were previously uncommon or found mainly in the elderly and which progressed rapidly into the rest of the population.
We evolved on a diet with an Omega 6 - Omega 3 balance somewhere between 1:2 and 4:1, currently it's something like 10:1 to 20:1 in favour of Omega 6s, a pretty huge shift along with the gross reduction in saturated fats, and actually things like lard which contain significant percentages of monounsaturated fats too.
Originally these "heart healthy" fats were also loaded with trans fats, but even without them they don't appear to be doing us much good.
It may not originally have been the carbs that led to a damaged metabolism, but once the damage has occurred dropping the carbs is the best way to deal with it. Of course returning to a more anatomically correct balance of healthy saturated and monounsaturated fats and more Omega 3s can't exactly hurt either.
