A recent study of military personnel deployed across many time zones illustrated the effectiveness of an Argonne-developed diet plan to prevent jet lag.
One hundred eighty-six soldiers participated in the study, which focused on National Guard troops traveling to and from South Korea.
Soldiers who did not use the diet were 7.5 times more likely to experience jet lag after arriving in South Korea than those who used the diet. Soldiers who did not follow the Argonne diet on the return trip were 16.2 times more likely to experience jet lag.
Ninety-five soldiers going to Korea used the diet and 39 soldiers used it for the return flight. The study found the Argonne diet to be effective in preventing jet lag during the return trip, but a history of jet lag and inactive lifestyle increased the odds of jet lag symptoms.
Jet lag occurs when the human body's inner clock is out of balance with powerful time cues from the external environment. Typical side effects include fatigue, insomnia, indigestion, irritability and general disorientation.
Traveling east generally causes more severe jet lag, the study reported.
Anyone planning to travel across three or more time zones this summer can lower the effects of jet lag by following the Argonne diet.
Normally, the body needs one day to adjust for each time zone crossed, but the anti-jet lag diet helps travelers adjust in a day or two -- even for trips halfway around the world.
The Argonne diet outlines an alteration of mealtimes, meal contents and social time cues to help reset the body's clock.
Day 1: Starting three days before
departure, feast on high-protein breakfasts and lunches to stimulate the body's active cycle and
eat a high-carbohydrate dinner to prepare the body for sleep.
Only drink caffeinated beverages between 3 and 5 p.m. during the first three days.
Day 2: Only eat light meals of salads,
soups, fruits and juices. Fast days help deplete the liver's store of carbohydrates and prepare the
body's clock for resetting.
Day 3: Feast again.
Day 4: When the departure day arrives,
fast again. Only drink caffeinated beverages in the morning when traveling west or between 6 and 11
p.m. when traveling east. Break the final fast at the destination's normal breakfast time. If the
flight is long enough, sleep until breakfast time and feast on a high-protein meal.
Former Argonne researcher Charles F. Ehret developed the program based on studies of body rhythms of animals. These cycles controlled by molecular "clocks" found in every cell of the body.
The diet is being used to help shift workers, such as power plant operators, adjust to rotating work hours.

Rhenette Preston, a biology and physical science teacher at Lindblom College Preparatory High School in Chicago, won Argonne's 2000 Ellis P. Steinberg Award for Pre-College Science Teaching.
The Steinberg Award is given annually to an Illinois science teacher who has shown excellence and innovation in teaching science. Preston received $500 and a plaque during a June 21 presentation at Argonne-East.
"Rhenette is an exemplary teacher who has the ability to stimulate the minds of her students," Lindblom Principal Fulton Nolen Jr. said.
Preston pioneered a summer enrichment program for incoming 7th graders to help them adjust to upper-level science, reading and math programs. She also helped to create the "Never Too Cool for After School" program. Dedicated to enhancing her teaching skills, Preston spends many Saturdays and summers at workshops -- including Argonne's Summer Science Teachers Workshop. She is a mentor for other science teachers in the Chicago Public Schools.
Preston encourages all of her students to participate in the science fair. She judges regional and state science fairs and served as a representative at the 2000 International Science Fair. Students in her Beta Club arrive as early as 7 a.m. to help demonstrate new experiments for Preston.
"I love seeing the looks on my students' faces when we do an investigation," Preston said. "My whole life has been to help students find out about science and to teach them that inquiry is exciting and rewarding."
Before teaching 7th and 8th grade science at Lindblom, Preston was an assistant principal and counselor in the Chicago Public Schools.
The Steinberg Award honors the commitment to excellence in science education as demonstrated by the late Ellis P. Steinberg, who built an illustrious career in nuclear chemistry. He worked on the research program that achieved the first controlled sustained nuclear chain reaction, supplied data on fission reactions for the Manhattan Project and led a research group at Argonne's Zero Gradient Synchrotron.
Steinberg was director of Argonne's Chemistry Division from 1982 to 1988. After retiring, he remained active in the Division of Educational Programs, working to improve the quality of science education and organizing workshops for students and teachers.
Students, parents and community members may submit nominations for the Steinberg Award. Selection criteria includes leadership in the science education community, participation in developmental programs that enhance scientific expertise and teaching skills, and encouraging students to participate in extracurricular activities related to science.
The Steinberg Award is run by Argonne and the Argonne chapter of Sigma Xi. Funds for the award are provided by family, friends and former colleagues of Steinberg.

John M. Carpenter, a senior physicist, has been named a fellow of the American Nuclear Society for leading the entire field of spallation neutron source design from its inception to its current state -- as exemplified by the Intense Pulsed Neutron Source (IPNS) at Argonne-East.
The society bestows the fellow designation to recognize outstanding accomplishment by its members.
In the 1970s, Carpenter, IPNS' first division director and now its technical director, originally devised a way to use neutrons created by the process of spallation for neutron scattering experiments. During spallation, charged particles are accelerated into a heavy-metal target, which emits pulses of neutrons.
As a result of Carpenter's initial efforts, Argonne developed the world's first sources of spallation neutrons, ZING-P and ZING-P', which led to the May 1981 startup of IPNS. Today, the IPNS, which is used for the study of atomic structure and motion in liquids and solids, is the most cost-effective of the U.S. Department of Energy's neutron sources.
Carpenter has been an advisor to nearly every facility and project in the area of spallation neutron source design.
The Argonne Running Club will hold two fun runs the week of Aug. 12-16 at Argonne-East.
A trail fun run will start at 7:15 a.m. Tuesday, Aug. 13, in the Waterfall Glen Parking Lot (Northgate Road and Cass Avenue). The event distance is four miles for runners and two miles for walkers. This run is on the path between Cass and Lemont roads.
On Thursday, Aug. 15, an on-site fun run will begin at noon at the Argonne Pool. The runners' route is three miles, and walkers will cover two miles.
Refreshments will be served at both events.
Q: Because of the on-going road construction on I-55 during the off hours, in which travel is down to one lane or the (exits to) Lemont and Cass avenues have been closed off, those of us who work during those "off-hours" have to find alternate routes to get to the lab. Could it be possible to open the Westgate entrance between the hours of, say, 11:30 p.m. and 12:30 a.m. to accommodate those of us who live south and west of the laboratory? It can help to cut down the travel time to work.
A: As in previous years, commuters throughout the Chicago metro area, at all times of the day, are experiencing pain and frustration about finding alternate routes and allowing for the extra time of traffic delays due to road construction and renovation. Many individuals from the south and west of the laboratory have indicated that even at 7 a.m., what was normally a 20- or 30-minute commute is now requiring that they start an hour earlier to get to work before 8 a.m.
While we sympathize with your situation, the suggestion of posting security officers at Westgate to permit late night access cannot be accommodated under heightened security requirements and our obligations to protect the site, the site occupants, and the resources of DOE and the laboratory. Even under normal circumstances, the protective force is fully engaged with increased patrols during off hours and reducing and restricting off-hours site access and activities through a single point. To open up additional entry points during the middle of the night or to divert security personnel from patrols and site surveillance activities would not be prudent stewardship of DOE and laboratory resources.
