The first comes from the web Flowingdata and represents how the consumption of various foods has changed in the US from 1970 to 2013. Click on this link to see the animated image, with the trend of each food every year.
The second one is a bit more complicated but very interesting and was published on CIAT website. It shows relationships between crops worldwide, according to the country of origin.
As explained in the "Description" tab, "These circular plots link the primary regions of diversity of crops (regions where crops were initially domesticated and evolved over long periods of time, and where the diversity of traditional crop varieties and related wild plants is especially high) with crops' current importance in regional food supplies, measured in terms of calories (kcal/capita/day), protein (g/capita/day), fat (g/capita/day), and food weight (g/capita/day). Each region has a color representing its own native crops and those colors are connected to other regions due the importance of those crops in the diets of other regions. The direction of the contribution is indicated by both the native region's color and a gap between the connecting line and the consuming region's segment. The magnitude of contribution is indicated by the width of the connecting line. Regional food supply values (per capita/day) were formed by deriving a weighted average of national food supply values across countries comprising each region, with national values weighted by population".
Click on this link and then on "View" (below "Diets"). Then you can "play" all over the graph with your mouse.
Two good examples of awesome infographics with a lot of information.
