National Fellowship to prepare graduate student for future in researchWith the goal of one day running his own research lab, food science and human nutrition graduate student Graham Redweik recently received a predoctoral fellowship that will give him the experience needed to find success in the future.

Redweik was one of 75 individuals nationwide awarded a

Auriel Willette receives annual installment from the NIH Institute on Aging for memory research
Auriel Willette, assistant professor in food science and human nutrition, received a grant of $243,137 from the NIH Institute on Aging to continue funding for a five-year project, officially set to continue until December 2020. The total amount of the grant is $881,730. The grant will fund a proof-of-concept clinical trial looking at the effects of intermittent calorie restriction on older adults with mild memory problems. Willette’s research will focus on whether weight loss in overweight to obese participants will raise insulin sensitivity and translate into improved brain function and memory.
Antioxidant SOD1 puts up fight, loses battle against toxic tau protein linked to Alzheimer’s diseaseA team of Iowa State University researchers is the first to identify the correlation between the antioxidant superoxide dismutase, or SOD1, with tau proteins in brains with Alzheimer's disease. The team's new research may explain why SOD1, which protects the brain, is also associated with deterioration in areas susceptible to Alzheimer’s disease.

Nuria Acevedo receives funding for underrepresented scholar program
Nuria Acevedo, assistant professor in food science & human nutrition, received $160,000 from the USDA National Institute of Food & Agriculture for Cyclone Scholars. This program has three main goals
to increase enrollment of underrepresented students in the food science and human nutrition program, provide them with experiential research opportunities, and ensure their retention in the program. By the end of this program the scholars will be prepared to enter careers in food science companies or continue their education in a graduate program.

Manju Reddy receives funding for wheat and corn flour research
Manju Reddy, professor in food science and human nutrition, received $18,961 from Nutrition International (Ottawa, Ontario, Canada) for the development of protocol to test the type of iron added to wheat and corn flours. While there are iron fortification guidelines currently in place, they appear to be ineffective in reducing the burden of iron deficiency anemia in developing countries, most likely due to ineffective quality control systems. This study will work to provide a cost-effective, rapid, and accurate test to identify the forms of iron added to flours to help government agencies check for compliance in food fortification programs.

Kevin Schalinske awarded funding to study polycystic ovary syndrome
Kevin Schalinske, professor in food science and human nutrition, and his laboratory group received a grant for $146,551 from the NIH Eunice Kennedy Shriver National Institute of Child Health and Human Development. The grant focuses on developing dietary strategies to support methyl group metabolism in polycystic ovary syndrome (PCOS). The research will utilize both a genetic and chemically-induced model of PCOS in mice and rats, respectively.
Searching for connection between egg consumption and athletic performanceDue to the nature of the sport, gymnasts’ joints take a lot of hits during practices and competitions. Researchers in the Department of Food Science and Human Nutrition wanted to see if regular consumption of eggs would have any effect on joint inflammation.

What you eat could impact your brain and memoryYou may be familiar with the saying, “You are what you eat,” but did you know the food you eat could impact your memory?

Assistant Professor Auriel Willette and his team of researchers in the Department of Food Science and Human Nutrition analyzed data and discovered a satiety hormone that,...

Shannon Coleman receives award for Food Safety Modernization Act Project
Shannon Coleman, assistant professor in food science and human nutrition and Human Sciences Extension and Outreach state extension specialist, received a subcontract of $50,410 from Tennessee State University as part of a three-year grant program. This award supports the implementation of the Food Safety Modernization Act (FSMA) regulations in communities in Iowa and the state of Tennessee. Signed into law in January of 2011, FSMA is the most comprehensive U.S. food manufacturing and agricultural production legislation in more than 70 years. The food safety law aims to ensure safety of domestic and imported foods by shifting focus of federal food regulatory agencies from response to contamination to preventive measures. Coleman will assist with the development of a Produce Safety Rule and Preventive Control for Human Foods Toolkits to engage extension professionals. She will use her subcontract to assist with developing short videos which cover critical pieces of the legislation for producers and processors.
