Lead author Sara A. Quandt, Ph.D., a professor of epidemiology and prevention at Wake Forest Baptist, said that CSAs, which link consumers to a local farm's produce over a growing season, have been proposed as a solution for disparities in fruit and vegetable consumption, though evaluation of such efforts has been limited. The typical U.S. diet fails to meet daily recommendations for fruit and vegetable consumption.
This CSA program, Farm Fresh Healthy Living of Forsyth County, N.C., was developed, administered, and evaluated by a partnership of university researchers, Experiment in Self Reliance Inc., a community nonprofit agency, and Harmony Ridge Farms, a Forsyth County, N.C., farm using organic practices.
"Expanding access to healthful foods is an important step in reducing health disparities," said Quandt. "The objective of this study was to test the feasibility of a CSA program for low-income families in Forsyth County."
The study appears last month in the Centers for Disease Control and Prevention's journal Preventing Chronic Disease.
For a small randomized, controlled feasibility study, Quandt and fellow researchers recruited 50 low income women with children, then divided them into an intervention group and a control group of 25 each. The participants ranged in age from 24 to 60; most were African-American and unmarried.
Intervention participants received a free box of fresh produce for 16 weeks from May through August 2012. They were also offered five educational sessions, including cooking classes, a farm tour and a grocery store tour with a dietitian that focused on healthful eating on a budget. The control participants did not receive education or the produce boxes.
The researchers observed a significant increase over the summer in the number of different fruits and vegetables in the households of the intervention group compared with the control group. The intervention group also reported greater increases in fruit and vegetable consumption.
"Although the increases in fruit and vegetable consumption in the intervention group did not reach statistical significance, they did show a trend in the right direction," said Quandt. "In a larger group, we would expect that the CSA program would make a noticeable impact on quality of the families' diets."
Intervention participants reported a willingness to pay at least a portion of the CSA cost in the future. In an overall evaluation of the Farm Fresh Healthy Living program, the participants reported positively on the variety of the produce provided, the better flavor of the local produce compared with grocery store produce, the chance to expose children to new foods, as well as the chance to eat foods that were too expensive to purchase at the grocery store. Some indicated problems with work schedules and transportation in picking up their produce box every week.
"This study shows that food from a CSA program has positive effects on recipient households," said Quandt. "CSA is a feasible approach and more study is needed. Altering some of the financial and operational aspects of traditional CSA programs will be necessary to improve the participation impact."
The study was supported by two National Institutes of Health grants (RC4 HL104866, T35 DK007400), and the Wake Forest Translational Science Institute, as well as in-kind contributions from Experiment in Self-Reliance Inc. and Harmony Ridge Farms.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
