Food studies is highly interdisciplinary across both science and social science fields. It can include anything pertaining to food and eating from how food is grown to when and how it is eaten to who eats it and with whom and the nutritional quality. Relevant publications are scattered throughout the literature and across academic fields for both current and historical work. In order to truly cover the literature it is necessary to search multiple indexes to the literature. Research in food habits published in the agricultural literature is often as useful as studies of food habits in anthropology or sociology studies. This paper addresses some of the major indexes across disciplines that have citations related to food studies.
