FSHN Leads the Way in Nutritional Sciences Research

FSHN faculty have always made exceptional contributions to research in their respective fields, and FSHN is back in the
headlines this year. Early in 2004, two of our faculty were featured in Institute of Food and Agricultural Sciences news reports in
recognition of their novel research findings.

Dr. Jess Gregory, FSHN Professor, along with Dr.
Andrew Hanson, Griffin Eminent Scholar from the UF
Department of Horticultural Sciences, guide an international
team of researchers that has begun untangling the genetic
code behind folate production in plants. The implications of
this discovery are very exciting: in the future, it may be
possible to develop food crops that are inherently rich in
folate, a vitamin that is essential for growth and
development. In developing nations, where folate deficiency
is a common problem, such crops could make an enormous
difference in the health of communities.
If their research team can manipulate the genes that help
produce folate in plants, then they can increase the amount of
folate the plant produces. This type of genetic engineering,
called "biofortification," results in crops that are fortified
with specific nutrients. Biofortification has already resulted
in the creation of a rice crop high in beta-carotene, a source
of vitamin A from plant-derived foods.
Here at the University of Florida, Drs. Hanson and
Gregory have focused on the tomato plant. Not only are
tomatoes consumed in many different cultures around the
world, they are also often eaten raw. And since folate is
unstable and can be lost when food is cooked, the tomato is
thus an ideal choice for this type of research. Many other
fruits and vegetables are also a good source of folate,
including spinach, broccoli, beans and peas, avocados,
oranges, and papayas.

Dr. Bobbi Langkamp-Henken, FSHN Associate Professor,
Kelli Herlinger-Garcia, FSHN Senior Biological Scientist, and
multiple FSHN undergraduate volunteers are members of a UF
team that studied how nutrition can help increase immune
function in the elderly. Dr. Langkamp-Henken led a study on the
effect of an experimental nutritional supplement on the ability of
older persons to fight off influenza. Because flu shots are less
effective in the elderly, they are considered an especially at-risk
population during flu season.
Thirty-four participants with an average age of 83
participated in the study. One group was given the nutritional
supplement beverage (a combination of various vitamins,
minerals, antioxidants, fiber, protein and energy) as well as a low
dose vitamin supplement for six months; another group was
given a control
beverage containing
just protein and energy, In this issue:

Alumni Success Stories Scott King

Scott King graduated in 2000 with his BS
in Food Science. A very active student, Scott
served as the Vice President of Food Science
for the Food Science and Human Nutrition
Club in 1998-1999, the Social Chair for the
FSHN Club in 1999-2000, and participated in
Institute of Food Technologists College Bowl
competitions in 1999 and 2000. Scott was also
the recipient of the FL Section Institute of
Food Technologists Grady W. Chism Jr.
Memorial Scholarship in 1999, and the
Southeastern Food Processors Association
Scholarship in 2000.
After graduation, Scott went to work for
PIC USA, a subsidiary of Sygen International,
in Kentucky. After two successful years at PIC, he was offered
and accepted a Quality Supervisor position with Kellogg's in
Pikeville, Kentucky. Just this spring, he was promoted to Plant
Quality Manager and is now the youngest person to hold this
position in Kellogg's North America. Scott is responsible for

managing the plant's quality assurance and food
safety programs. He also supervises the lab
technicians and sanitarians.
Scott tells us he loves working for Kellogg's.
He says they have a fantastic corporate philosophy,
and the fact that they are one of the largest food
companies in the United States is a testament to their
continuous efforts to produce high quality food
products, encourage employee development, and
keep the consumer happy.
Scott admits that one of the attractions of this
particular job was the location. For someone who
enjoys camping, hiking, fishing, and mountain
biking, eastern Kentucky offers a wealth of
recreational opportunities.
We all look forward to seeing Scott and other alumni every
year at the Institute of Food Technologists Annual Meeting. It's a
chance to catch up with old friends and find out where our
alumni have gone. If you see Scott King in Las Vegas this July,
please join us in congratulating him on all his successes!

Research, continued from page 1

Biofortified Tomatoes
Aside from increasing folate synthesis, another goal is to prevent the natural reduction of folate in ripening tomatoes,
particularly in the edible fruit itself. It is hoped that continued research will pave the way for folate biofortification and thus
improved health around the globe.
Flu-Fighting Nutrition
showed a fourfold increase in antibodies, indicating that the elders were responding to the flu vaccine. Those participants drinking the
experimental formula also suffered fewer days of flu-like symptoms than the control group 78 total days compared to 156 total days.
This study is important for many reasons. Previous studies have shown that nutrient deficiency can negatively impact immune
function and thus the body's response to vaccines, but in this study Langkamp-Henken made the link between good nutrition and a
specific clinical outcome. For health practitioners, this is clear evidence that good nutrition can not only help the elderly respond better
to flu vaccines, but may also help reduce days of cold and flu symptoms. This is especially important because this study found that only
12 of the 34 participants regularly took vitamins prior to the study.
Although the liquid supplement used in this study is not available to the general public, Langkamp-Henken suggests that all
seniors should take an inexpensive, commercially available multi-vitamin supplement. All evidence suggests that this one simple step
may help keep our senior citizens in better health.

Supplier's Night Update

This year's FL Section Institute of Food
Technologists' Supplier's Night was held on
February 26th in Orlando. Many students from the
FSHN Club volunteered to help at the event, and in
return FL Section generously agreed, as they do
annually, to support the FSHN Club financially for
the upcoming year. FL Section IFT student reps
Gillian Folkes (PhD student working with Dr.
Murat Balaban) and David del Pozo Insfran
(PhD student working with Dr. Steve Talcott)
organized and supervised the undergraduate
volunteers, and a special thanks goes out to all the
students who worked so hard to support the FSHN
Club and FL Section. FSHN is grateful for the
many professional opportunities IFT offers to our

Newest Faculty Addition

Please join us in welcoming Dr. Mitch Knutson to
the FSHN Department. Dr. Knutson received his BS
from Iowa State University in 1992 with a double
major in French and Biochemistry, and his PhD in
Nutrition from the University of California, Berkeley
in 1998. He comes to us most recently from the
Harvard School of Public Health Department of
Nutrition, where he was a Postdoctoral Fellow for
several years. Dr. Knutson's research focuses on the
biochemical and molecular mechanisms of iron transport and nutrition,
and he has published and presented numerous studies in these areas. With
years of classroom experience, both at Berkeley and Harvard, Dr. Knutson
will teach a FSHN graduate course in Advanced Human Nutrition and is
also developing a new course for Nutritional Sciences undergraduates on
laboratory techniques in nutrition research. He will also serve as a faculty
advisor to students in Nutritional Sciences.

FSHN Achievements
