The data suggest an increase in fat consumption, although I didn't make that claim in the last post because I'm aware of the limitations of the dataset. What I wrote is that the data don't support a decrease in fat consumption, which is accurate.
Looking at the graph above, you can see the abrupt increase in fat consumption in 2000. I corrected the data for this artifact in the graph below:
Here's a graph of macronutrient intake since 1909, adjusted for loss and the artifact in 2000:
The graph suggests that fat consumption has gradually increased over the last century (+ 30%), carbohydrate consumption has decreased and then rebounded (currently - 6%), and protein consumption has increased modestly (+ 10%).
The modern "obesity epidemic" began in earnest between the 1976-1980 and 1988-1994 NHANES survey periods, and corresponded with an increase in calorie intake. According to the adjusted data, this increase was 350 calories per day since 1970. 65 percent of the increase in calories can be attributed to carbohydrate, 24 percent can be attributed to fat, and 11 percent to protein.
