Food and Mood: Daily Associations Between Missed Meals and Affect Among Early Adolescents.

Objective: Youth frequently miss meals and experience hunger, yet no studies have assessed how these experiences relate to changes in daily emotional states. This daily diary study examined associations of missing breakfast, missing lunch, and hunger with daily positive and negative affect among young adolescents.

Methods: A community sample of 133 grade 5 and 6 students (50.

Relative food insecurity, mental health and wellbeing in 160 countries.

Food insecurity contributes to various stress-related health problems and previous research found that its association with mental illness is stronger in more affluent countries. We hypothesised that this pattern is a function of relative deprivation whereby the severity of individual food insecurity relative to others in a reference group determines its associations with mental health and wellbeing after differences in absolute food insecurity are controlled for. Using survey data from the Gallup World Poll collected in 160 countries and a measure of relative deprivation (Yitzhaki index), we found that relative food insecurity-based on national or regional reference groups-related to more mental health symptoms, lower positive wellbeing and lower life satisfaction after controlling for absolute food insecurity, household income, and country differences.

Growing Mouse Oocytes Transiently Activate Folate Transport via Folate Receptors As They Approach Full Size.

The folate cycle is central to cellular one-carbon metabolism, where folates are carriers of one-carbon units that are critical for synthesis of purines, thymidylate, and S-adenosylmethionine, the universal methyl donor that forms the cellular methyl pool. Although folates are well-known to be important for early embryo and fetal development, their role in oogenesis has not been clearly established. Here, folate transport proteins were detected in developing neonatal ovaries and growing oocytes by immunohistochemistry, Western blot, and immunofluorescence.
