Messy Eating, Samantha King, R Scott Carey, Isabel Macquarie, Victoria Millious, Elaine Power Jun 2019

Messy Eating, Samantha King, R Scott Carey, Isabel Macquarie, Victoria Millious, Elaine Power

Environmental Studies

Literature on the ethics and politics of food and that on animal-human relationships have infrequently converged. Representing an initial step towards bridging this divide, Messy Eating features interviews with thirteen prominent and emerging scholars about the connections between their academic work and their approach to consuming animals as food. The collection explores how authors working across a range of perspectives—postcolonial, Indigenous, Black, queer, trans, feminist, disability, poststructuralist, posthumanist, and multispecies—weave their theoretical and political orientations with daily, intimate, and visceral practices of food consumption, preparation, and ingestion.

High Quality Proteins Can Impact Circulating Homocysteine Levels., Kevin L. Schalinske Mar 2019

High Quality Proteins Can Impact Circulating Homocysteine Levels., Kevin L. Schalinske

Kevin Schalinske

The amino acid composition of a protein can tell you a lot about it’s health implications. For example a protein source high in sulfur amino acids (methionine and cysteine) can affect methionine metabolism and, ultimately, health. Cysteine is a conditionally essential amino acid, because it can be synthesized endogenously from methionine. Thus, when a dietary protein provides enough methionine beyond the need for cellular protein synthesis, the remaining surplus can be used to synthesize cysteine. Therefore, when a dietary protein has a cysteine concentration in balance with methionine, the need to utilize methionine for its synthesis is reduced. This ...

Development Of A Food Safety Training For A Prison Farm: Challenges And Solutions, Angela M. Shaw, Kara Helterbran

Angela M. Shaw

Workers on prison farms in the United States commonly grow produce and row crops and raise livestock. Teaching good agricultural practices to prisoners and prison staff increases the safety of the food produced and reduces the likelihood of an illness outbreak. We developed a food safety curriculum for use on prison farms in Iowa. In developing the curriculum, we encountered many challenges that resulted in modifications in the content and delivery method. We present the content of the curriculum and provide educators with a better understanding of challenges and potential solutions related to working with prison farms.

Calibrating A Food Thermometer, Lorna Saboe-Wounded Head

Lorna Saboe-Wounded Head

Using a properly calibrated thermometer is essential to ensure that foods are cooked to the correct temperature, chilled rapidly, or held at proper temperatures after cooking. A thermometer should be calibrated before the first use, after an extreme temperature change (such as going from hot food to frozen food), if the thermometer is dropped, or if it is used many times. Clean thermometers after each use by washing in hot soapy water, rinsing, sanitizing, and air drying.

Dramatic growth in herbicide-resistant (HR) weeds in the United States threatens farm profitability and may undercut environmentally beneficial farming practices. When HR weeds move across farm boundaries due to ecological processes or human action, a common pool resource challenge emerges, requiring farmer cooperation to manage such weeds effectively. We investigate the scope for cooperative management using responses to a national survey on HR weed issues to test a recursive model of three preconditions for collective action: (1) concern about HR weeds migrating from nearby lands; (2) communication with neighbors about HR weeds; and (3) belief that cooperation is necessary for ...
