Americans place high value on butterfly royalty. A recent study suggests they are willing to support monarch butterfly conservation at high levels, up to about 6 ½ billion dollars if extrapolated to all U.S. households.
If even a small percentage of the population acted upon this reported willingness, the cumulative effort would likely translate into a large, untapped potential for conservation of the iconic butterfly. (more…)
Scientists find that essential fatty acid found in vegetable oils does not promote inflammation in humans
COLUMBIA, Mo. — A typical American consumes approximately 3 or more tablespoons of vegetable oil each day. Vegetable oils, like those from soy, corn and canola, are a significant source of calories and are rich in linoleic acid (LA), which is an essential nutrient. Since the 1970s, researchers have known that LA helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing. A new study from the University of Missouri contradicts that claim.
In the study, “Effect of Dietary Linoleic Acid on Markers of Inflammation in Healthy Persons: A Systematic Review of Randomized Controlled Trials,” researchers at the University of Missouri and the University of Illinois found that no link exists between vegetable oil consumption and circulating indicators of inflammation that are often associated with diseases such as heart disease, cancer, asthma and arthritis. While earlier animal studies have shown that a diet rich in LA can promote inflammation, MU animal sciences researcher Kevin Fritsche says that humans respond to LA differently. (more…)
Since its inception in 1909, University of Minnesota Extension has worked with farmers to find solutions to their biggest challenges. And, since we all eat—our biggest challenges. For the past 25 years, Extension has shared the U’s expertise by educating agriculture professionals, who in turn have the most influence on crop farmers today.
Keeping agriculture professionals on top of current research helps ensure economically and environmentally responsible cropping decisions are made throughout the state. (more…)
A diabetes researcher’s take on dietary sugar
With all the talk these days about fructose, glucose, sucrose, high-fructose corn syrup, and sugar in general, it can be hard for a health-conscious person to sort out the truth.
“A lot of people are putting out their ideas as established fact,” says diabetes researcher and endocrinologist John Bantle, M.D., a professor of medicine at the University of Minnesota. “It’s hard to find the actual facts and then to interpret them.”
Bottom line: Too much sugar is bad, if only for the excess calories. But the story isn’t quite so simple. (more…)
*Water significant limiting factor in growing crops like switchgrass*
Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.
They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.
“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (more…)
Wind turbines in Midwestern farm fields may be doing more than churning out electricity. The giant turbine blades that generate renewable energy might also help corn and soybean crops stay cooler and drier, help them fend off fungal infestations and improve their ability to extract growth-enhancing carbon dioxide from the air and soil.
The preliminary findings of a months-long study that examines how wind turbines on farmlands interact with surrounding crops were presented on December 16 at the annual fall meeting of the American Geophysical Union in San Francisco. The presentation was made by researcher Gene Takle of the U.S. Department of Energy’s Ames Laboratory and Julie Lundquist, assistant professor in the University of Colorado at Boulder’s atmospheric and oceanic studies department.
