It’s Time to Rethink America’s Corn System

Only a tiny fraction of corn grown in the U.S. directly feeds the nation’s people, and much of that is from high-fructose corn syrup

What would such a system look like?

This reimagined agricultural system would be a more diverse landscape, weaving corn together with many kinds of grains, oil crops, fruits, vegetables, grazing lands and prairies. Production practices would blend the best of conventional, conservation, biotech and organic farming. Subsidies would be aimed at rewarding farmers for producing more healthy, nutritious food while preserving rich soil, clean water and thriving landscapes for future generations. This system would feed more people, employ more farmers and be more sustainable and more resilient than anything we have today.

It is important to note that these criticisms of the larger corn system—a behemoth largely created by lobbyists, trade associations, big businesses and the government—are not aimed at farmers. Farmers are the hardest working people in America, and are pillars of their communities. It would be simply wrong to blame them for any of these issues. In this economic and political landscape, they would be crazy not to grow corn; farmers are simply delivering what markets and policies are demanding. What needs to change here is the system, not the farmers.

And no matter what happens, this won’t mean the end of corn. Far from it. Corn crops will always be a major player in American agriculture. But with the current corn system dominating our use of natural resources and public dollars, while delivering less food and nutrition than other agricultural systems, it’s time ask tough questions and demand better solutions.

    It would be interesting to see what would happen if we stopped massively subsidizing commodity crops like corn and just put in a price floor / ceiling to keep farmers from going out of business and to keep people from starving. In addition, farmers that preserve their topsoil and use sustainable practices on their land should be rewarded while farmers that whittle away the essence of their land should pay for the damages they cause, like the anoxic "dead zone" at the mouth of the Mississippi, among other maladies.

    We could also crack down on the horrible waste problems, overuse and abuse of antibiotics and the inhumane conditions associated with Concentrated Animal Feeding Operations (CAFOs). And we could also crack down on slaughterhouses so that we don't have E coli outbreaks in our meat supply.

    After we regulate a lot of the barbarism and needless destruction out of our food supply, would grass-fed beef be competitive with the still wasteful system of growing industrial monocrops of corn and feeding it to cattle? Look, as long as we subsidize and look the other way on environmental destruction only to produce artificially cheap meat and "food products" that make us fat, we're giving ourselves a really bad deal in several respects. Ending subsidies would improve the federal deficit while getting rid of the artificial price advantage that industrial meat and processed foods have over more "natural" foods would decrease healthcare costs a great deal over the long term. Subsidizing our own health problems with deficit spending is a really bad idea.

    The best approach is to do away with both open and hidden farm subsidies and let the pieces fall into place. Food prices should be a higher percent of family income. A burger should cost $3 and not $1.50.

    As for healthy vs unhealthy, etc. Let the market decide. I'm guessing that folks will make better food choices over the coming decades and this will be met by the market. Any intervention by government will be bogus as the food lobby has too much influence on government dietary recommendations....still having kids eat red meat and drink milk everyday.

    I grew up on a farm. I have to agree that raising animals in the raccoon infested barn was unhealthy for both animals farmers and consumers. The use of antibiotics is clearly a substitute for rational production methods.

    While artificially cheap meat and processed "foods" aren't all that great health-wise, the fact that they are some of the cheapest calories out there means that people consume them way more than they should. It's this overconsumption brought about by artificially low prices that leads to a lot of the health problems we see today. Eliminating artificial price supports could go a long way in diversifying the American diet, but we'd also need to make sure that healthy food choices are also available, especially in the inner city "food deserts" that occur in many major cities.

    Making our cities and towns more walkable / bikeable would provide more outdoor exercise opportunities that are vanishing in suburban areas and maybe replace some car trips with walking / biking, increasing activity levels in some people.

    When Americans chow down, three times a day, every day, they know they're getting a treat pigs like.

    This is how one feeds pigs in Big Agro. It's very unhealthy and it's disgusting. And the reason it's in place is because it makes money, and what is the health and well being of the American people, when balanced against the profit of a few oligarchs, who wouldn't eat their own product or feed it to their own children, if you held a gun to their heads.

    It's amazing. You can hardly find anyone anymore that thinks producing ethanol from corn is a good idea but the corrupt political system we laughingly call democracy seems wedded to it.
    As for wasting calories, as the author would put it, producing meat from corn - well that's what people want. Not so much corn but more meat.
    And for those who think food is too cheap in America - well I just shake my head. Life is hard enough for so many in this economy and they want to make it harder.

    I think it time to rethink our system that allows someone from a taxpayer subsidized institute to write articles like this that are full of misinformation and have little real world validity. I think that Mr. Foley needs to climb out of the ivory tower and find out some realitites about farming and corn production and our agricultural system, other then what he reads in journal articles.

    srtolman I'm not in an Ivory tower but agree with the article as the food system is failing to make healthy foods but high profit junk foods instead.

    For instance using 10 lbs of corn to make 1 lb of FAT not to mention makes the cows sick vs just feeding them grass as they were evoled to do saves 40% of the crop right there. Plus gives far better, more healthy meat.

    Let's remember ethanol might start with 40% of corn but it uses less than 50% of that, just the starch with all the oil, protein, etc left but with a nice extra protein of yeast added making it a far better human food than raw corn is, a very poor food.

    So in reality ethanol uses little of the US food crop vs cattle getting most of the 40% of raw corn and the 20% of ethanol corn means it's cattle, not ethanol, driving corn prices plus multiple drought arond the world including here driving up the price.

    And that is made worse by speculators betting on futures 10x's the amount of corn actually grown.

    I'm getting away from corn fed beef as not healthy enough for me both from the excess fat corn feeding does to shipping, feed lots excesses it's better to buy local fed, butcher beef.

    And if they want real productivity they need to bring back the grasslands of the west and put bison back on them needing little input for great food.

    It's the relative cheapness of the least healthy foods that's the problem. If the government subsidized stuff like arugula and kale up the wazoo like they do corn, I'm sure things wouldn't be so bad. I mean, people are ALREADY paying for these subsidy programs due to government spending priorities and reduced health, so all that cheap, processed "food" isn't a cheap in the long run as people think.

    The fundamental problem mentioned in this great article is the government subsidies! If we ended all the subsidies - with great benefit to the American taxpayers - the rest of the problems would also end - or at least be greatly relieved.

    I agree that it is time to rethink America's corn system. Another thing that the author didn't mention is that a big percentage of corn grown in the US is RoundUp ready corn, and is regularly drenched in RoundUp. I don't believe it is good for soil to be regularly soaked in Roundup.

    It would take an article longer than Mr. Foley’s to explain and refute all the misinformation provided in both the article and the comments. I'm reminded of Pres. Reagan's famous remark "it's what people "know" that just isn't right that's dangerous". There are so many facts being stated here that are widely accepted but are just flat wrong that it is disturbing. One silly example is the claim that eating corn makes cattle sick. Do rational people actually believe farmers would feed something to their herds that cause them sickness? Corn is an incredible engine of starch and protein production. It is renewable, incredibly efficient - a national treasure. This essay as well as the comments demonstrate well that Americans, including professors, need to visit a farm. If they want to affect farm and food policy, they need to acquire a better understanding that is based on factual information

    I agree that corn ethanol is a waste.

    However, those claiming to feed cattle with grass should go do some math. It doesn't work on the scale necessary. If everyone ate organic people making minimum wage would only be eating rice and beans, if they are lucky.

    Nitrogen fertilizers are here to stay and the "dead zones" are so over exaggerated. A couple percent of the Gulf of Mexico is "dead" for a couple months out of the year. Meanwhile, you and I are able to eat at a somewhat reasonable cost. Do some math and figure out how much more we would be paying for food to get rid of this *horrible* dead zone. Its not pretty. Its just something we have to accept.

    When you point your finger, you got THREE of them pointing back at you!

    "Escherichia coli, although considered to be part of the normal gut flora for many mammals (including humans), has many strains. Strain E. coli 0157:H7 is associated with human illness (and sometimes death) as a foodborne illness. A study by Cornell University[24] has determined that grass-fed animals have as much as 80% less of this strain of E. coli in their guts than their grain-fed counterparts, though this reduction can be achieved by switching an animal to grass only a few days prior to slaughter. Also, the amount of E. coli they do have is much less likely to survive our first-line defense against infection: stomach acid. This is because feeding grain to cattle makes their normally pH-neutral digestive tract abnormally acidic; over time, the pathogenic E. coli becomes acid-resistant.[25] If humans ingest this acid-resistant E. coli via grain-feed beef, a large number of them may survive past the stomach, causing an infection.[26] A study by the USDA Meat and Animal Research Center in Lincoln Nebraska (2000) has confirmed the Cornell research."

    http://en.wikipedia.org/wiki/Cattle_feeding#Corn-fed

    Sorry, but in agriculture, cash is king, and if they can just pump cattle full of antibiotics and cross their fingers that E. coli outbreaks don't happen all that often, they they'll try to get away with it. I mean, this is the same industry that brought you "Mad Cow" disease by feeding cows to cows, so if something will add a fraction of a penny to the bottom line, they'll try it as long as regulators will let them.

    For a century and a half, we've been mining the corn belt -- for topsoil. The Great Plains originally had six or more feet of magnificently rich soil. A few decades ago I read a calculation that, among the other costs of Midwest corn production, one bushel of corn cost one bushel of topsoil. This counts losses to wind and water erosion in addition to the organic material burned out of the soil each year by plowing, discing and other disturbance.

    I suggest you do some math at the health care cost we as a country are incurring as a result of obesity, which is directly related to the low cost of corn and the meat produced by it (not to mention the environmental cost of growing the corn). Maybe we would be better off if minimum wage people could only afford to eat rice and beans and occasional meat. Our over-consumption of meat is not sustainable and bad for our health. I agree that there is not enough grassland for all of the corn fed cows to switch over to grass-fed. I believe the solution is to get rid of the corn subsidies, and let the cost of beef go up, which will cause people to eat less beef, and thus ranchers will reduce number of cows to a number that can be sustained by grass-feeding, and our country will become less overweight, and our healthcare cost will decrease.

    Stop producing ethanol from corn, it's a waste of energy. Stop producing corn syrup, it's high sugar not healthy. Stop feeding cattle with corn, feed them grass. Eat corn and less meat.

    There are more cows and pigs than humans by weight, and they eat more food than all of humanity. Then we complain a billion people are starving and earth cannot produce enough food. Nonsense! Slaughter all the livestock and you'll double the grains supply to people plus a lot of beef and pork.

    Instead of raising meat products as live animals, why not make use of stem cell research to grow our meat. For example grow a nice rib eye steak or chicken breast. If we can grow ears and skin why not dinner?

    Yet another corn basher. He will have to take a number and get in line. I have always felt the condescension from critcs of ag is really based more in reverse biggotry. An urban vs. rural mindset. Basically, Starbucks coffee drinkers vs. the hometown cafe coffee drinkers. They both like coffee they just go to different places to get it. But such a wide gap between the two. We need to attach responsiblity to those in the Ivory Tower with an agenda. Just follow the money trail with the climate change hoax.

    Re comment #24, That is the most intelligent comment here.
    That wonderful angus steak came from corn, those plump, tender chickens ate corn, that excellent bacon and ham we love, corn. We wouldn't feed it to them and they wouldn't produce the great results if corn weren't good for them. Isn't it odd that corn wasn't a 'problem' until it was mandated to be used for ethanol?

    To be clear, I farm and raise corn, livestock and own a portion of ethanol production. My huge government subsidy on my corn production this year = 1.8% of my gross income on corn acres. My subsidy on crop insurance was 2.8% of my gross income. That taxpayer investment prevented an ad hoc disaster program during one of the worst droughts on record. I raise corn because it is the best crop for the acres I care for. Ethanol happens to be the least expensive oxygenate and best source of octane for liquid fuel. We need correct information when "rethinking systems". Statements like "huge subsidies" don't ring true with me. Is the corn system perfect? Far from it, but real farmers work hard every day to make it better.

    If you trade energy as octane as in C-8, H-18 you lose versus C-1 H-4 burning to making C-2 H-5 OH-1.

They actually get by selling more crap by adding our good product. Whoa. How ironic? They don't have to refine as clean. Simple enough to understand? Number I hear is just under a $1/gal for this. It may not be env economics but rather blending economics. You are entitled to your opinion though.

We can build all the green space and bike trails the people want but you just can't make kids get off their devises. Can we make better choices? Sure, and we should. To make one product the villain is shallow. Why will nobody stand up and tell the emperor he's naked? Eat less, make better choices and exercise.
