A Technical and Policy Case Study of Large-Scale Rescue and Redistribution of Perishable Foods by the "Leket Israel" Food Bank.

Background: Food banks seeking to rescue and redistribute highly nutritious perishable foods to simultaneously alleviate food insecurity and reduce food waste often encounter practical, ethical, and political dilemmas.

Objectives: We present a case study of "Leket Israel," an Israeli food bank that uses an effective large-scale logistical model for the rescue and redistribution of perishable food and discuss the challenges and solutions it offers.

Results: The organization operates in a rich country plagued with poverty and inequality, where the government passively encourages nongovernmental organizations to respond to the serious and growing problem of food insecurity.

Dihydrofolate reductase 19-bp deletion polymorphism modifies the association of folate status with memory in a cross-sectional multi-ethnic study of adults.

Background: Folate status has been positively associated with cognitive function in many studies; however, some studies have observed associations of poor cognitive outcomes with high folate. In search of an explanation, we hypothesized that the association of folate with cognition would be modified by the interaction of high-folate status with a common 19-bp deletion polymorphism in the dihydrofolate reductase (DHFR) gene. To our knowledge, the cognitive effects of this gene have not been studied previously.
