One thing all those "Brits were healthier under rationing" articles that crop up in the UK press every time the government wants to play Nanny State forget to mention is that by dragging things out for ten years after the war (on various pretexts) the created a boomerang effect in the generation of children who endured it.

But my point is that how much of that "healthy" created by rationing also created a backlash when people deprived for so long just ate, and ate and ate as much sugar, fat and meat as they could get; and I don't blame them.
The fact that processed/convenience foods came in at the same time, made that a bigger problem for over-all health than it probably would have been otherwise.
What you also have to remember is that before the war, there were the Haves and the Have-nots. Before the war the Haves, had food, and ate meat - for breakfast, lunch and dinner. A meal was not a meal without meat. They had extravagant puddings based on cream and sugar. The Have-nots, did not enough to eat, and ate what they could, when they could.
In some senses everyone's diets improved, The Have-nots had enough to eat, and they were given access to meat, eggs, and cheese, something they rarely ate before. The Haves, stopped eating meat, cream and sugar all the time, and started eating more vegetables, and whole foods. But Food was boring.
Practically no one had used herbs before the war, to make vegetables, or grains and pulses interesting. And spices were pretty well unavailable in the war, and would have been expensive, even before the 100% tax that was placed on luxury ( non essential) goods. Food was tasteless. People used what little that could to make it more interesting, meat, cheese, tomatoes, and those goods were in short supply. Not sure salt and pepper were freely available either.
For many, as soon as the restrictions were lifted they dug into the new over-processed, over-sugared, overly-sweet "junk-foods" of the middle 1950's and going on into the 1960's.
These foods must have been seen as the most delicious thing most people had ever tasted. To us they seem, junk, but to the people of the 50's and 60's, most of whom had been eating a diet of boiled veg, or boiled grains and pulses, these foods must have seemed like manna.
When rationing ended stuff did not magically appear in shops. In the first video, the man talked about how the government agreed to supply you a set amount of food each week. OK in the war the supply often broke down, and when you could get it, it was of poor quality, but more often that not, when it came to rationed foods, people got something. Once rationing ended, the first to the shops, sometimes got something, the rest, got nothing. My mum used to tell about the end of sweet rationing, sweets effectively disappeared from the shops.
So the end of rationing did not mean people could rush out and buy what they wanted. Most stuff was largely unavailable, and people relied on vegetables, or grains and pulses, boiled of course for sustenance. Fats were still difficult to obtain, and vegetable oils are actually a modern invention. People fried in lard in the 50's and 60's, and animal products were still difficult to obtain.
Also after the war, Britain had huge debts. Britain's war loans were not finally paid off until the 70's(?). I remember my parents telling me, that Britain had finally paid off our last war loan! As Britain had massive debts, the government placed import controls, and foreign exchange restrictions on the population. No one could import stuff, or take money out of the country, *without* a permit from the foreign office. There were some exceptions, but the government tried as hard as possible to stop money leaving the UK.
Those import controls / foreign exchange restrictions stayed in place till 1970, when the UK joined the EU. So no one was going to import spices. OK the explosion of curry houses in the 60's meant curry powder was available, but not the individual spices. And the sweet spices, such as cinnamon, nutmeg, vanilla, and so on for baking were available, but the plethora of spices, or Asian, or tropical flavours, or whatever, we take for granted were unheard in the 50's and 60's, and I would say the 70's and 80's as well.
I remember being in Belgium in the early 2000's, and trying to buy cumin, cardamom etc. to make my own curry spice. I simply could not buy them. And there were certainly no oriental / tropical/ whatever flavours out there either. And Belgium was not that far behind the UK.
So for those living in the 50's, 60, and 70's, fast food, prepared meals, tinned stuff, etc., tasted wonderful compared to boiled veg/grains/pulses, they were eating at home. And you did not have to cook them!
IMO, I have to look at the social context, to understand, why people snapped these foods up. I think the world has changed out of all recognition in the last 30 years. Some of it is fantastic, and some not so good. But I am not sure the "Good 'Ol Days" were actually that good.
