If you look at the chart and treat the blue (sweeteners) and purple (fats and oils) streaks as a single one, together they increase 1.6 times from around 25% in 1914 to 40% in 2004. That's a huge increase! In fact, these two calorie sources are the only ones that consistently increased over the given period. I am surprised anyone is even talking about grains and meat.
