The presence of Salmonella, including antibiotic-resistant Salmonella, has been frequently reported in terrestrial animal-derived foods such as meat, poultry, and dairy products, as well as in aquaculture products. Identification of the significant food sources that harbor …

Modeling The Impact And Accelerating The Process Of Transitioning To A Sustainable Healthy Diet Through Decision Support Systems, Prince Agyemang

Graduate Theses and Dissertations

Food production and consumption are essential in human existence, yet they are implicated in the high occurrences of preventable chronic diseases and environmental degradation. Although healthy food may not necessarily be sustainable and vice versa, there is an opportunity to make our food both healthy and sustainable. Attempts have been made to conceptualize how sustainable healthy food may be produced and consumed; however, available data suggest a rise in the prevalence of health-related and negative environmental consequences of our food supply. Thus, the transition from conceptual frameworks to implementing these concepts has not always been effective. This paper explores the …

Characterization Of Blueberry (Poly)Phenolics In Foods, Their Metabolites In Human Biological Samples And Anti-Inflammatory Effects Of Phytochemicals In Vitro, Laura Felgus-Lavefve

Graduate Theses and Dissertations

Blueberries’ popularity is in part supported by the health benefits associated with their consumption. Research has strongly focused on their polyphenol and anthocyanin concentration, one of the highest amongst commonly consumed foods. Polyphenols have demonstrated antioxidant effects in vitro, and consuming polyphenol-rich foods is associated with protective effects towards non-communicable diseases, but their direct bioactivity in the human body remains to be fully understood. It is estimated that about 90 to 95% of the initial polyphenol intake reaches the colon without being absorbed. Instead, phenolic compounds go through extensive biotransformations, consisting of catabolism into smaller compounds mostly carried out by …
