You hear all the time from low-carb/keto/carnivore people that the introduction of low-fat products and the governmental push of low-fat diets is a major cause of today's health problems.
So I actually tried to dig up nutrition statistics over the ages.
If you actually look at the statistics, fat intake has increased dramatically from 1900-1970, and then decreased only very slightly from 1970-2000. So where is that low-fat era they're talking about?

Trends in Intake of Energy and Macronutrients --- United States, 1971--2000
Of course, it's not all animal fat, but still. Linoleic acid has more than doubled from 1900-1970. Starch has decreased like crazy.
I have no idea what they're defining as a "low fat diet", but I wouldn't say more than 20% of calories AT MAX.
