<\/a><\/p>\n At first glance there has been an unsettling trend in the supply of fruit and vegetables in the US (see graph above). \u00a0We seem to be reversing some of the consumption gains that public health experts<\/a> would see as important – even critical. \u00a0The USDA Economic Research Service tracks the farm-level supply of many commodities<\/a> and expresses it relative to the population of the country. \u00a0Overall, this data set appears to indicate a decline in per capita fruit and vegetable supplies from a peak in the late 1990s (\u00a0Note: these numbers are not a direct measure<\/a> of how much fruit and vegetables a typical American consumes because there is some loss along the commercial chain<\/a> and also in the consumer’s home). \u00a0Most public health and nutrition experts would say that it would be better if Americans ate even more fruit and vegetables<\/a> because of their value in addressing obesity, cancer and other health concerns. \u00a0How does that goal reconcile with these recent supply statistics? Fortunately, a closer look at the details reveals a more nuanced situation in which our US produce supply is getting:<\/p>\n Looking at the same time period, the fruit supply has also shifted towards greater diversity (see table below). \u00a0On a weight basis, the big winners have been avocados, pineapples and strawberries, but 10 fruits have seen more than a 25% increase and 5 fruits have increased more than 100%. \u00a0The biggest supply declines are for oranges, bananas, grapefruit and apples – again, traditional “mainstays.” \u00a0The gains are for more exotic options.<\/p>\n <\/a><\/p>\n <\/p>\n Overall, the fruit and vegetable supply is growing in crops that supply a diverse collection of desirable phytochemicals with positive health associations. \u00a0This is probably the most encouraging trend in recent years. \u00a0Not surprisingly, most of the big “winners” have been crops that are delivered with reliable taste quality<\/a>.<\/p>\n In 1960, very few vegetables were imported to the US; since that time there has been a slow but steady increase in imports so that by 2009 they represented ~21% of the total (see chart below). \u00a0Per capita domestic production of vegetables had risen significantly in the 1980s, but leveled off during the 1990s. \u00a0Since around 2004, domestic vegetable production has declined ~30 lbs per person. \u00a0 The most significant growth in vegetable imports since 1990 has been for artichokes, asparagus<\/a>, brussels sprouts, garlic, cucumbers, peppers, eggplants, squash and tomatoes. By 2009, more than 40% of all these crops were imported. \u00a0Even crops which were not often imported in 1990 (carrots, mushrooms, broccoli), now have more than 10% imports.<\/a> (Crop-by-crop trend lines can be found on SCRIBD<\/a>)<\/p>\n <\/a><\/p>\n In the early 1970s, only about 25% of all US fruit was imported. \u00a0Since then, there has been a steadily increasing trend in imports. Nearly 50% of US fruit was imported by 2009. \u00a0Since 1990, pineapples and limes have gone from ~55% US grown to 100% imported. \u00a0Papaya imports have increased from 25% to 95%. Kiwifruit imports have grown from 55% to 80%. \u00a0Avocados have risen from 10% to 70% imports and grapes from 35% to 50%. \u00a0Smaller increases have also been seen for tangerines, cantaloupe, and lemons. \u00a0Even strawberries are approaching 10% imports. (Crop-by-Crop trend lines can be found on SCRIBD<\/a>)<\/p>\n <\/p>\n <\/a><\/p>\n There are probably several reasons for the increasing role of imports in the US fresh fruit and vegetable supply which vary by crop. \u00a0First, many popular fruits can only be grown in tropical or semi-tropical climates. \u00a0Such environments are limited in the US and those that exist are often under urbanization pressure (CA, FL, HI). \u00a0Secondly, many produce crops are labor intensive to produce. \u00a0Since the US does not currently have a workable guest worker system, it is more practical to import crops from regions with a more adequate or predictable source of labor. \u00a0Thirdly, there is an ongoing trend towards “protected culture”<\/a> for high value crops (greenhouses, shade houses, rain shields…). \u00a0Canada and Mexico have been major innovators in that area and their highly productive systems have become important for many crops. \u00a0 Fourth, American consumers have come to expect year around supplies of popular produce items, and this requires sourcing from different regions at different times of year. \u00a0Finally, as US population has grown and fruit and vegetable consumption has increased, it is increasingly difficult to find enough suitable farmland<\/a> in terms of climate and water availability.<\/p>\n Most health professionals would favor substantially higher per capita produce consumption<\/a> than we see today. \u00a0Imports are a major means by which such goals are likely to be achieved<\/a>. \u00a0Some observers will be concerned that the increasing import trend is problematic because of “food miles.” \u00a0Whether the energy or greenhouse gas “footprint” of imported crops is high depends a great deal on the basic productivity by region and also depends on the means of shipping<\/a>. \u00a0In any case, it is impractical to locally produce the quantity and diversity of fruits and vegetables that Americans have proven willing to consume, let alone a higher goal. \u00a0If we wish to harmonize our national goals for both “sustainability” and “public health,” \u00a0the best strategies will include components such as:<\/p>\n Graphs by Steve Savage based on USDA-ERS data<\/a>. \u00a0A more extensive set of graphs is available for download on SCRIBD<\/a>. \u00a0My email is savage.sd@gmail.com. \u00a0My main blog site is Applied Mythology.<\/a><\/p>\n Featured image credit:<\/strong> Bruce Tuten at flickr<\/a> under a Creative Commons license<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Most public health and nutrition experts would say that it would be better if Americans ate even more fruit and vegetables than they do because of their value in addressing obesity, cancer and other health concerns.
