BACKGROUND Fresh Facts is a 30-day email-delivered intervention designed to increase the fruit and vegetable consumption of Australian young adults. This study investigated the extent to which the program was acceptable to members of the target audience and examined the relationships between participant and intervention characteristics, attrition, effectiveness, and acceptability ratings.

OBJECTIVE To explore whether area-level socio-economic position or the form of retail stream (conventional v. farmers' market) is associated with differences in the price, availability, variety and quality of a range of fresh fruit and vegetables. DESIGN A multi-site cross-sectional pilot study of farmers' markets, supermarkets and independent fruit and vegetable retailers. Each was surveyed ...

The microbiological quality of selected fresh vegetables; lettuce, cabbage, mukunuwenna, gotukola, and tomato were assessed from different market types in the Kandy district. Fifty samples of each vegetable were tested for viable bacterial count (VBC), Salmonella spp., Listeria monocytogenes and Escherichia coli O157:H7, before and after washing using tap water. The average VBC in unwashed vege...

As living materials, post-harvested fruits and vegetables continue their metabolic activity, exhibiting progressive biochemical changes. Optimisation of environmental conditions during storage of these fresh commodities is required in order to increase their shelf life. In this work we use P systems to abstract molecular interactions that occur between plant organ, film and surrounding atmosphe...

Fresh produce supply chains have special characteristics, notably, that the quality of the product (fruit or vegetable) deteriorates continuously over time, even under ideal conditions. In this paper, we begin with explicit formulae for fresh produce quality deterioration based on chemistry and temperature and provide a path-based framework. We then focus on farmers’ markets, the popularity of ...

In a prospective cohort study of 1271 Massachusetts residents 66 years of age or older, we examined the association between consumption of carotene-containing vegetables and subsequent five year mortality. Dietary information was obtained by food frequency questionnaire in 1976. The relative risk of cancer mortality was examined within quintiles of green and yellow vegetable score (calculated f...
