Predicting Anthocyanin Content In Canned Black Beans Based On Color, Courtney Simons, Juan Osorno, Lauren Fuelling

Lake Campus Research Symposium Abstracts and Posters

The dark color of black beans is associated with the presence of anthocyanins. These are phytochemicals known to contribute to improved health due to their antioxidant, anti-inflammatory, anti-viral and anti-cancer benefits. Therefore, the color of canned black beans could potentially predict the total concentration of anthocyanins present. To test this hypothesis, 12 black bean varieties obtained from North Dakota State University Bean Breeding Program were cooked and evaluated for anthocyanin content and color characteristics (L*, hue and chroma) of end-product. Pearson Correlation statistics was applied to determine if color values could be used as a reliable index to predict relative …

Stunting And Infectious Disease In Ethiopian And Zambian Children, Alyssa Arndt

NUTR/GLST 498b: Global Research Experiences in Nutrition and Health

PURPOSE: To evaluate whether children who are malnourished/stunted are more likely to have experienced infectious disease.

METHODS: 6th and 7th students (n=546) were interviewed about health history and assessed using anthropometry.

RESULTS: Children who are short for their age also have higher rates of stunting. Malaria is the most experienced infectious disease.

CONCLUSIONS: Given that malaria was the most common infectious disease experience listed among middle school children, and that those who have experienced disease are more likely to be stunted, increased malaria prevention methods may improve the long-term health of Ethiopian and Zambian schoolchildren.

Cost-Effective Method To Determine Effect Of Ethylene Gas On Ripening Of Bananas, Ashley Siefring, Devin Siefring, Brooke Gaerke, Colby Homan

Lake Campus Research Symposium Abstracts and Posters

Ethylene, a gaseous plant hormone associated with fruit ripening processes, is produced by bananas as they ripen. Hence the presence of ripe bananas could trigger the ripening of green bananas if they are stored together. To test this hypothesis, green bananas, all at the same stage of maturation was collected and separated into two groups. One group was stored alone while the other group was stored with ripe bananas. The rate of ripening between the two groups was observed over 2 weeks and measured using a standard banana color chart. The study confirmed our hypothesis that green bananas ripen faster …

Comparisons Of Celiac Disease And Non-Celiac Gluten Sensitivity, Victoria Thomas

Senior Honors Theses

Celiac disease (CD) and non-celiac gluten sensitivity (NCGS) are often confused or grouped together due to their commonalities. However, this is careless behavior because there are clinically significant differences between the two diseases. Similarities between them include varying degrees of damage or permeability in the lining of the small intestine, involvement of the innate immune system, alleviation of symptoms upon implementation of a gluten-free diet (GFD), and the possibility for complications if the pathology is not adequately treated. Despite these similarities, minor details such as the following make CD and NCGS worth differentiating: the question of gluten as the true …

Experimental Archaeology And Brewing Beer: A Modern Reproduction Of The "Hymn To Ninkasi", Mahayla Roscoe 20

Honor Scholar Theses

Alcoholic beverages, and beer in particular, have had an extensive impact on human civilization. People have been brewing beer for thousands of years, and some scholars even argue that it was humanity’s thirst for beer rather than a hunger for bread that motivated the domestication of cereal grains ca. 9500-8000 B.C.E. If this argument is to be believed, beer would have acted as a precursor to the Neolithic Revolution and inspired people to develop agrarian economies and abandon their nomadic lifestyle. By the time that the Sumerian civilization in ancient Mesopotamia arose, beer production was a well-known and respected craft. …

We identified a dietary pattern associated with sulfur-metabolizing bacteria in stool and then investigated its association with risk of incident CRC using data from a large prospective study of men.

Methods: We collected data from 51,529 men enrolled in the Health Professionals Follow-up Study since 1986 to determine the association between sulfur-metabolizing bacteria in stool and risk of CRC over 26 years of follow-up. First, in a subcohort of 307 healthy men, we …

Integrating The Ecosystem Services Framework To Define Dysbiosis Of The Breastfed Infant Gut: The Role Of B. Infantis And Human Milk Oligosaccharides, Rebbeca M. Duar, Bethany M. Henrick, Giorgio Casaburi, Steven A. Frese

Department of Food Science and Technology: Faculty Publications

Mounting evidence supports a connection between the composition of the infant gut microbiome and long-term health. In fact, aberrant microbiome compositions during key developmental windows in early life are associated with increased disease risk; therefore, making pertinent modifications to the microbiome during infancy offers significant promise to improve human health. There is growing support for integrating the concept of ecosystem services (the provision of benefits from ecosystems to humans) in linking specific microbiome functions to human well-being. This framework is widely applied in conservation efforts of macro-ecosystems and offers a systematic approach to guide restoration actions aimed to recover critical …
