The Great Sugar Conspiracy
Somehow - don't ask me how, but somehow - the information in
Pure, White and Deadly (1972) got buried by the sugar industry under anti-fat propaganda, so that the manufacturers promoting low fat diets took most of the fat out of processed foods. This took most of the flavour out of the foods which they replaced with sugar.
And so forth and blah. Oh, and Richard Nixon.
The fat's going down the sugar's going up and we're all getting sicker and sicker.
As a simple conspiracy addon: when the sweetening properties of the harmless vegetable Stevia became more widely known, the sugar industry pushed every lobby button they had to defend their markets.

The book is from 1972. In the 50ies and 60ies books of Adelle Davis became popular on Food and health covering many aspects. In 1970 Linus Pauling (twofold Nobel Prize winner) wrote "Vitamin C and the common cold".
I started studying chemistry in 1974, specialising in biochemistry. Some of these books I bought, some I borrowed.
The general assumption of all these books was that the change to mass agricultural production and mass processing of the ingedients served the industry much more than our health, and that many illnesses could be traced back to our nutrition that had deviated far from our original food on which our human evolution had optimised our metabolism.
Current DNA mutation research shows nicely that in the past 20,000 years many of our DNA mutations had to do with adapting our metabolism to the change of food like better abilities to handle starch rich food, milk lactose, teeth decay protective saliva, etc, etc.
On a timescale longer back in time: We have currently roughly 5% Neanderthaler DNA and the mainstream hypothesis, as a partial explanation, is that when we migrated to inland Europe and Asia, we were confronted with new lightly toxic bioflavonoids etc in vegetables there and the fastest way to handle that was not changing slowly by evolutionary adapting our own DNA, because some interbreeding with Neanderthalers that had already those protecting genes was quicker.
Assuming that evolutionary development is more or less stagnated nowadays on nutritional metabolic pathways, we are where we are: a non-optimal health mismatch between easy available food and our genes.
Back to Pure, White and Deadly and all those other books: they were all run over except Linus Pauling!
PWD by the power of the food industry, Adelle Davis by the Science community because she made too many mistakes (although her general message is now mainstream in Science), Linus Pauling original insights simply became outdated by the fast developing biochemistry. No wonder because the DNA model was only discovered in 1953. There is however the Linus Pauling Institute with a wealth of reliable nutrition/health knowledge as a strong "beacon of hope" under siege of the food and pharma industry.

From the conspiracy point of view to consider: whereas the white sugar is mainly defended by the food and beverages industry, everything to do with health from vitamins, minerals, antioxydants, etc, etc is under attack of the powerful pharma industry as well. Medicins make much more money than lowcost to produce micronutrients. The beverage industry is losing ground (attacked by the WHO) and retreats slowly.
Personally I think the individual that does not want to spend almost a study on it, has no chance to do the right thing in an easy social acceptable way (buying food in retail) against these powerful forces.
If politicians were the first to invent fake news, the pharma/nutrition industry, the (electronic) tabloids, as well as all kind of food faddist with good intentions have greatly boosted the development of badly checked news or fake news.
To consider also:
Our metabolism is extremely complex. Science is charting that.
The METLIN database collecting all metabolites. Counter well over 900,000.
