As physicians we recognize that lean meats may be a healthy part of almost anyone’s diet. However, based on the preponderance of evidence compiled by scientists and health experts across the globe, there is little doubt that a diet high in red and processed meats is linked to serious health risks and that we would all be wise to keep our consumption down. New dietary guidelines, recently released by the United Kingdom’s Scientific Advisory Committee on Nutrition (SACN) bolsters this conclusion. The SACN’s Iron and Health 2010 report advises that Britons can reduce their risk of colorectal cancer while maintaining healthy levels of iron by keeping their red meat and processed meat consumption to 70 grams or about 2 ½ ounces a day.
Cutting back on red and processed meat could do more than just ward off colorectal cancer. Research has linked it to other diseases such as diabetes, cardiovascular disease and even Alzheimer’s. A landmark United State’s study, published in 2009 in the Archives of Internal Medicine, Meat Intake and Mortality, which included data from more than half a million members of the AARP, concluded red and processed meat intakes were associated with modest increases of “total” mortality in addition to cancer and cardiovascular disease mortality. An equally important Harvard study, published in Circulation in 2009, that followed more than 84,000 female nurses, found that red meat intake increases the risk of coronary heart disease. More importantly researchers concluded that shifting sources of protein from meat based to plant based could reduce the risk of coronary heart disease.
The Washington Post reports that cutting down on red meat could save an estimated 3,800 Britons from dying of bowel cancer every year. However, SACN researchers made it clear that their report did not address other potential health risks associated with meat consumption, which means many more lives could be saved from other preventable diseases.

Once again the conflict between the use of corn for ethanol production and the amount of corn available for consumption by swine, beef, dairy and poultry has come into conflict.
Corn prices have increased an astounding 85% in 6 months.
There simply is not enough corn to go around, and thus the price of corn increases RusBankNet. When corn prices rise, prices of other grains also rise. Wheat, rice, even barley rise.And surprise, surprise, the price of processed food rises. Why is this?
First, one has to look into the dark world of agricultural economics. Corn, in many ways similar to oil, is a world-wide commodity. Many countries produce corn (for example, China grows more corn than the United States, but has a lot more people to feed). But only a few countries have enough left over to sell on the world markets. Argentina along with the United States are the main exporting countries. And when the corn crop declines in other consuming countries such as China or Mexico, they buy more corn on the open market. And as these countries move “up the food chain” to consume more red meat, pork, dairy and poultry, they need more corn. So they buy corn from those few countries that have some to spare. But with several countries bidding for corn and a limited supply, the price goes up. It is an “inelastic” situation. If corn is not available, wheat will do nicely, so will sorghum, etc. So these grains become more valuable. And “wala” food prices rise. Most affected are foods that rely on corn, such as pork, beef, chickens and eggs. But bread soon follows. and this brings food riots. Even the recent uprising in Egypt is being blamed in part on rapidly increasing food prices (I feel this is a stretch,but do not claim to be well-informed in such matters). Even the price of tamales goes up in Mexico. Sure they use white corn, but white corn is also good pig feed so it is bidding against our yellow corn.
Ethanol plays a central role in this fray. Processing a bushel of corn gives about 2.8 gallons of ethanol (less if one converts the energy in ethanol to a gallon of gasoline). The government in its wisdom has mandated that we must use about 12 billion gallons of ethanol by next year. That translates to a lot of corn, about 25% of all the corn grown in the United States. In Iowa, by far the largest ethanol producing state in the nation, about half the corn goes to ethanol. So when supply goes down while demand goes up, the market “bids” for corn. They buy corn from other uses by paying a higher price, and the higher price encourages farmers to plant more corn next year. More grassland and highly erodible land go into cultivation. This increases erosion and water pollution, and turns the countryside even more into a row crop desert.
It seems pretty clear that changing climate is impacting the discussion. This past year, corn production dropped in the United States by about 9%, a huge decline. Bad weather in other parts of the world have cut down on grain production as well. In the meantime, demand for meats and for foods made from corn continues to increase.
The struggle between the farm state politicians who push for ethanol from corn (and they must or they are summarily dismissed by the farm block supporters such as Farm Bureau and National Corn Growers) and the rest of the country who are being pressured by food wholesale and retail interests, as well as by swine and poultry growers). It is all part of the farm bill, no matter how altruistic the discussion may be.
I have said for years that ethanol policy was really corn policy. Its objective was to assure a demand for corn and a stable high price. Well it worked. Now we have the unintended consequences. At least for the next few months higher prices for many food staples will increase. And to hear some say it, corn based ethanol is to blame. I tend to agree, but as you can see, it is not simple. But then nothing in the convoluted world of farm policy is.
