This course equips students with the economic principles used for food policy analysis, applying the methods of economics to the major food and nutrition policy problems of the United States and the world.
Many problems in agriculture, food and nutrition are inherently geographic in nature. For example, livestock production is increasingly concentrated in large feeding operations, leading to new spatial patterns of water and air pollution or foodborne illness. Spatial clustering is equally important for food consumption, nutrition and public health, as in hunger hotspots, food deserts and disease corridors.
This intensive course provides presentations, readings and activities related to the broad range of community-based nutrition research, programs and policies in the U.S. today. Public health efforts in communities are implemented in many different types of settings, including community non-profit agencies, worksites, health centers, clinics, hospitals, schools, churches, supermarkets, recreational and sports centers, councils on aging/senior centers, and emergency feeding sites.
This course examines the United States food policies governing the use of diet and health information in commercial communications. In the mid-1980s, the food industry began, for the first time in modern history, to use health claims in food advertising and labeling. This proved to be a highly effective marketing method for the food industry.
This course will cover the functions of mammalian organisms as we understand them at various levels of organization - organ system, organ, cellular and subcellular levels. Our goal is to provide a working knowledge of the fundamental properties and regulation of these systems so that the student can understand and relate this material to that learned in other basic science courses with particular emphasis on those related to nutrition.
This course introduces basic principles and applications of statistics to problems in clinical research. Topics covered include descriptive statistics, probability and random variation, sampling, hypothesis testing, proportions, measures of frequency, t-tests, chi-square tests, one-way analysis of variance, correlation, linear regression and nonparametric statistics. This course has a required Laboratory (NUTR 0206.1L) linked to the NUTR 0206.01 course and it is cross-listed with Sackler's CTS 0527.
This course covers basic epidemiologic methods and concepts, including study design, calculation and interpretation of measures of disease frequency and measures of effect, sources of inaccuracy in experimental and observational studies, causal inference, and an introduction to the statistical evaluation and interpretation of epidemiological data. Students will discuss historical examples and recent studies in order to apply their understanding of abstract concepts and specific quantitative methods to the interpretation and critique of published work.
Consumption of sugary drinks may lead to an estimated 184,000 adult deaths each year worldwide, according to research published today in the journal Circulation and previously presented as an abstract at the American Heart Association Council on Epidemiology and Prevention in 2013.
Results Can Inform Research on Beverage Health Impacts and Nutrition Policy Development
Data on beverage intakes in 187 countries reveal diversity in existing intakes and trends in global consumption of sugar-sweetened beverages, fruit juices and milk. A research team led by scientists from the Friedman School of Nutrition Science and Policy at Tufts University reported today in PLOS ONE that the consumption of all three types of beverages was lowest in East Asia and sugar-sweetened beverage consumption was highest in the Caribbean.
In the first study to investigate blood lipid levels in association with consumption of sugar-sweetened beverages (SSBs) in a racially and ethnically diverse sample of Boston area schoolchildren, researchers found there was an inverse association between SSB intake changes and HDL-cholesterol increases (HDL-C is the "good cholesterol").
