I recently had some questions about which fruits and vegetables are most commonly consumed. The USDA Economic Research Service reports data on per-capita availability of different foods. This is not a direct measure of consumption per se, but it is an indirect extrapolation of what was left in the U.S. for consumption after accounting for exports and storage. Their latest update was for the year 2015.
Here is per-capita "consumption" of fresh fruit.
And, per-capita "consumption" of fresh vegetables is below.
Do any of these findings surprise you? One of the results that was a little surprising to me is that melons were the 2nd most commonly consumed fresh fruit. Why are melons so commonly consumed? There are likely a variety of reasons, but I suspect price is one factor.
Here is 2016 retail data from USDA Economic Research Service for fresh fruit. I've shown prices in $/lb and $/cup equivalent ("a 1-cup equivalent equals the weight of enough edible food to fill a measuring cup") for some of the most commonly fresh fruits.
Why do people eat a lot of fresh melons? Apparently one reasons is that they're relatively affordable.
