Plants exhibit different developmental strategies than animals; these are characterized by a tight linkage between environmental conditions and development. As plants have neither specialized sensory organs nor a nervous system, intercellular regulators are essential for their development. Recently, major advances have been made in understanding how intercellular regulation is achieved in plants on a molecular level. Plants use a variety of molecules for intercellular regulation: hormones are used as systemic signals that are interpreted at the individual-cell level; receptor peptide-ligand systems regulate local homeostasis; moving transcriptional regulators act in a switch-like manner over small and large distances. Together, these mechanisms coherently coordinate developmental decisions with resource allocation and growth.

Currently, the sole strategy for managing food hypersensitivity involves strict avoidance of the trigger. Several alternate strategies for the treatment of food allergies are currently under study. Also being explored is the process of eliminating allergenic proteins from crop plants. Legumes are a rich source of protein and are an essential component of the human diet. Unfortunately, legumes, including soybean and peanut, are also common sources of food allergens. Four protein families and superfamilies account for the majority of legume allergens, which include storage proteins of seeds (cupins and prolamins), profilins, and the larger group of pathogenesis-related proteins. Two strategies have been used to produce hypoallergenic legume crops: (1) germplasm lines are screened for the absence or reduced content of specific allergenic proteins and (2) genetic transformation is used to silence native genes encoding allergenic proteins. Both approaches have been successful in producing cultivars of soybeans and peanuts with reduced allergenic proteins. However, it is unknown whether the cultivars are actually hypoallergenic to those with sensitivity. This review describes efforts to produce hypoallergenic cultivars of soybean and peanut and discusses the challenges that need to be overcome before such products could be available in the marketplace.

“American Manna: Religious Responses to the American Industrial Food System” is an investigation of the religious complexity present in religious food reform movements. I conducted ethnographic fieldwork at four field sites. These field sites are a Jewish organic vegetable farm where the farmers begin their days with meditation, a Christian raw vegan diet center run by Messianic Jews, a Christian family that raises their cattle on pastures and sends them to a halal processing plant for slaughter, and a Jewish farm where Christian and Buddhist farm staff helped to implement shmita, the biblical agricultural sabbatical year.
The religious people of America do not exist in neatly bound silos, so in my research I move with the religious people to the spaces that are less clearly defined as “Christian” or “Jewish.” I study religious food reformers within the framework of what I have termed “free-range religion” because they organize in groups outside the traditional religious organizational structures. My argument regarding free-range religion has three parts. I show that (1) perceived injustices within the American industrial food system have motivated some religious people to take action; (2) that when they do, they direct their efforts against the American food industry, and tend to do so outside traditional religious institutions; and finally, (3) in creating alternatives to the American food industry, religious people engage in inter-religious and extra-religious activism.
Chapter 1 serves as the introduction, literature review, and methodology overview. Chapter 2 focuses on the food-centered Judaism at the Adamah Environmental Fellowship at the Isabella Freedman Jewish Retreat Center in Falls Village, CT. In Chapter 3, I discuss the Hallelujah Diet as prescriptive literature and as it is put into practice at the Hallelujah Diet Retreat Center in Lake Lure, NC. Chapter 4 follows cows as they move from the grassy hills of Baldwin Family Farms in Yanceyville, NC to the meat counter at Whole Foods Markets. In Chapter 5, I consider the shmita year, the biblical agricultural sabbatical practice that was reimagined and implemented at Pearlstone Center in Baltimore, MD during 2014-2015. Chapter 6 will conclude this dissertation with a discussion of where religious food reform has been, where it is now, and a glimpse of what the future holds.
