Aging And Fermentation As Adaptive Food Management Strategies In The Arctic, Celeste Giordano May 2017

Aging And Fermentation As Adaptive Food Management Strategies In The Arctic, Celeste Giordano

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation is composed of three papers: one published article, one article under review for publication, and one published commentary. Chapter 1 provides an introduction to the dissertation as a whole – a work that investigates food aging and fermentation techniques in an indigenous Yup’ik Alaskan community, proposes an adaptive explanation for these strategies in the circumpolar north, and explores the potential importance of them cross-culturally and evolutionarily. Chapter 2 is a paper that describes the seal poke storage system – an indigenous food preservation and storage technique that Yup’ik Alaskans used to manage food security up until approximately one ...


A Rural And Urban Study Of The Food Environment In Select Nevada Geographies, Joseph Nickelson May 2017

A Rural And Urban Study Of The Food Environment In Select Nevada Geographies, Joseph Nickelson

UNLV Theses, Dissertations, Professional Papers, and Capstones

National and county level examination of urban and rural food environments has taken place, but primary validation of venue existence and in-venue data are lacking. The literature show disparities in access to healthy foods through low density of large grocers/supermarkets, low variety and quality of produce and higher prices for a healthy diet in rural versus urban geographies. Rural areas are of unique concern due to poor health indicators such as higher obesity rates, higher diabetes rates, lower incomes and lower educations than urban residents. The goal of this study was to explore differences in the community and consumer ...


Understanding Perceptions Of Genetically Modified Food Among Natural Food Shoppers In Southern Nevada, Christian Murua-Aceves May 2015

Understanding Perceptions Of Genetically Modified Food Among Natural Food Shoppers In Southern Nevada, Christian Murua-Aceves

UNLV Theses, Dissertations, Professional Papers, and Capstones

Today, 85% of corn, 93% of soybeans, and 88% of cotton in the U.S. are genetically modified (GM). Using laboratory methods, genes from one species, such as a plant, can be transferred to an unrelated species, such as an animal. Genetically modified crops may lead to higher yields, have improved food quality, texture, and nutritional value, and have an increased shelf life.

Despite these promising benefits, the potential health risks relating to the consumption of GM food remain inadequately assessed. Genetically modified food is not subjected to rigorous safety testing, such as epidemiologic studies, to identify potential health risks ...


An Evaluation Of Lead In Imported Candies Within Clark County, Nevada, Usa, Lee Reuben Ibarra May 2010

An Evaluation Of Lead In Imported Candies Within Clark County, Nevada, Usa, Lee Reuben Ibarra

UNLV Theses, Dissertations, Professional Papers, and Capstones

Imported candies from Latin America pose a danger to children because of the potential for those candies to contain harmful levels of lead. This study sought to identify characteristics of imported candies that typically display higher concentrations of lead. This study also explored the Integrated Exposure Uptake Biokinetic model developed by the EPA. Using lead exposure data specific to Clark County, Nevada, the IEUBK model was used to estimate the amounts of candy a child would have to consume in order to raise his blood lead level to over 10µg/dL (the federal allowable limit).

The results showed that candies ...


An Analysis Of Restaurant Food Safety Violations: Human Factors, Non-Human Factors, And Food-Borne Illness, Jai Choung Apr 2010

An Analysis Of Restaurant Food Safety Violations: Human Factors, Non-Human Factors, And Food-Borne Illness, Jai Choung

UNLV Theses, Dissertations, Professional Papers, and Capstones

An estimated 76 million food-borne illnesses occur in the United States each year, causing 325,000 hospitalizations and 5,000 deaths, according to the U.S. Food and Drug Administration. Food safety is an increasingly important topic to governmental food regulators, not only in trying to reduce the number of illnesses from contaminated food. Governmental regulators also are becoming aware of the vulnerability of the food supply chain as a target for bioterrorism. Recommendations have been developed to protect the U. S. food supply from terrorism, but little of the research and recommendations relate to the food-service level.

Eighty percent ...
