Anyway, the phrase "healhty" in relation to food is a bit of a trigger phrase to me nowadays, healthy how? It's completely lacking in nuance. Apples are healthy, except when you eat 200 seeds at which point the cyanide gets to a lethal dose. Granola is healthy, unless you eat it three times a day and little else. You get the idea. The problem there is "x is healthy" makes people overconsume it and ignore anything that isn't marked "healthy".
"healthy" eating takes work, study, and moderation.
He was a practicing GP and whenever asked to give some advice himself he said that people and lifestyles were too varied to give any advice more specific than "Eat mostly fresh fruit and vegetables, cut down on cigarettes and alcohol, and do some exercise".
I think point is less to stay ignorant and more to focus on macro-level changes (water > soda/beer, vary your starches, get sugar from fruit, avoid "filling up" on purely protein) rather than obsessing over this or that micronutrient and trying to boil it all down into a perfect formulation that you consume in a sludgy pancake-batter-tasting "shake" twice a day.
Speaking of things from back in the day, an episode of GI Joe featured this idea (only it was dumping truckloads of apples onto a giant gelatinous blob to kill it).
There was a time after prohibition when the prevailing theory was that vodka was healthier than whiskey because it was clear and whiskey wasn't.
Our educational institutions marched an entire populace right into obesity because the government insisted the food pyramid was scientific, and not the result of lobbying.
Honestly it's a bit wild to me that we ever think we know anything for certain.
