The overall aim of the present project is to investigate if intake of cod in pregnancy has impact on infant development up to 12 month. 142 pregnant women will be allocated into two groups, one counsuming cod two times the week for four months and one group will continue to follow their habitual diet. To study this, urine samples, dietary data and blood samples from the mother and from the infant, as well as data on neurodevelopment and cognitive functioning will be collected at several time points.
The Vitality HealthyFood benefit is a three-tiered incentive program designed to encourage healthier food choices amongst members of Discovery Health's Vitality program. Once enrolled in the benefit, participating members can receive 10%, 15%, or 25% cash-back on the healthy foods they purchase at selected grocers. And, while overall enrollment in the program is high, there is particular interest in increasing enrollment in the benefit amongst Vitality members with diabetes. One presumed barrier to enrollment in the benefit amongst members with diabetes is a misperception of the particular relevance of the benefit and healthier food choices for their personal health. Improved messaging regarding the HealthyFood benefit and its particular salience for individuals with diabetes may be an effective means of increasing activation of the benefit in this population. The proposed study will be a collaboration between Discovery Health/Vitality and researchers at the Perelman School of Medicine at the University of Pennsylvania. In the proposed RCT, Vitality members with diabetes will be randomised to different types of messages regarding the HealthyFood benefit. The investigators will then compare the effectiveness of these different messaging strategies at increasing activation of the HealthyFood benefit amongst Vitality members with diabetes.
The investigators hypothesize that monetary incentives and messaging, such as making nutritious foods relatively less expensive than less nutritious foods and framing the price difference in a positive or negative way, will influence purchasing behavior of households.
Background: - The National Cancer Institute has been studying health risks to people in New Mexico at the time of the first nuclear bomb test. This was called the Trinity nuclear test. It took place in 1945. Researchers want to also learn about Native Americans and Hispanics at that time. They want to learn about their way of life and their diets. This will give a more complete picture of the health risks to people in New Mexico in 1945. Objectives: - To learn about the activities and eating habits of Hispanic and tribal communities during the 1940s. - To see if a group of Hispanic and Native Americans who were living in New Mexico in 1945 can be gathered. Eligibility: - Native American or Hispanic adults who were alive in 1945. They must know firsthand about the lifestyle and diet in New Mexico at that time. Design: - Participants will have 1 visit. They will be interviewed at a place like a library or office. They will answer questions about their lifestyle and diet around 1945. This will take up 60 90 minutes. - Participants may agree to have their interviews taped. Their names will not be kept with their answers from the interviews.
Data on the diet and nutritional status of adolescent girls in Zambézia Province, Mozambique was collected. A cross-sectional study was carried out in 2010 in two seasons, January-February and May-June.

Almost half of the Dutch population is currently characterized by overweight and obesity. Losing weight is not the problem in obesity treatment, it is the seemingly obligatory weight regain after weight loss: the yoyo-effect. The primary objective of this study is to investigate the association between the weight-loss-induced cellular stress response and the rate of weight regain. The secondary objective is to investigate the differences in cellular stress response and weight regain after rapid and slow weight loss. To investigate this, subjects will receive meal replacements replacing either all or part of the daily meals during the intervention period. THe first group will consume 500 kcal/d diet for 5 weeks while the second group consumes a 1250 kcal/d diet for 3 months, both followed by 1 week normalization and a 2 week strict weight maintenance diet. During the 9-month follow-up period subjects will receive dietary advice according to the Dutch recommendations for healthy eating. The association between the amount of weight regain after the weight loss period and changes in adipokines, parameters of adipocyte metabolism, in vivo adipose tissue metabolism, adipocyte extracellular matrix gene expression profiles, adipocyte stress protein expression and gene polymorphisms in selected genes.
El Valor de Nuestra Salud [The Value of Our Health] is a 5-year study (2010-2014) involving grocery stores in San Diego County funded by the National Cancer Institute. The purpose of the study is to determine whether an in-store program can promote healthy foods through grocery stores. Sixteen stores in San Diego County will participate in El Valor de Nuestra Salud. The stores that participate in this study will be randomly assigned to either the intervention (program and evaluation) or control (evaluation only) group. We will test various strategies to promote healthy food shopping among customers of small-to-medium size Latino/Hispanic grocery stores. These strategies include changes to the store environment, food marketing efforts, and training of sales associates. Our evaluation protocol will determine whether the project is successful at improving aspects of the store and the employees, as well as whether customers shop for and eat healthier food products. The primary aim of the study is to evaluate the impact of the El Valor de Nuestra Salud intervention on consumption of fruits and vegetables among store customers.
This study aims to evaluate a nutrition labelling program in improving university canteen customers' dietary pattern and behavioural determinants (e.g. knowledge).
Health outcome studies should examine food patterns, because foods are consumed together and nutrients are metabolized jointly. To examine associations between food patterns and markers of systemic and vascular inflammation at baseline, in a population-based cohort in Malmö, Sweden, and after 13 years of follow-up food pattern associations with CVD incidence.
