To explore whether improvements in psychological well-being occur after increases in fruit and vegetable consumption.
Carotenoids represent some of the most important secondary metabolites in the human diet, and tomato (Solanum lycopersicum) is a rich source of these health promoting compounds. In this work, a novel and fruit-related regulator of pigment accumulation in tomato has been identified by Artificial Neural Network Inference Analysis (ANN) and its function validated in transgenic plants. A tomato-fruit gene-regulatory network was generated using ANN and transcription-factor gene-expression profiles (Tfs) derived from fruits sampled at various points during development and ripening. One of the Tfs with a sequence related to an Arabidopsis PSEUDO RESPONSE REGULATOR 2-LIKE gene (APRR2-Like) was up-regulated at the breaker stage in wild type tomato fruits and, when over expressed in transgenic lines, increased plastid number, area and pigment content; enhancing the levels of chlorophyll in immature unripe fruits and carotenoids in red ripe fruits. Analysis of the transcriptome of transgenic lines over expressing the tomato APPR2-Like gene revealed up-regulation of several ripening-related genes in the over-expression lines providing a link between expression of this tomato gene and the ripening process. A putative orthologue of the tomato APPR2-Like gene in sweet pepper was associated with pigment accumulation in fruit tissues. We conclude that the function of this gene is conserved across taxa and that it encodes a protein that has an important role in ripening.
Residents of some low-income neighborhoods have limited access to fresh fruits and vegetables. In 2008, New York City issued new mobile fruit and vegetable cart licenses for neighborhoods with inadequate availability of fresh produce. Some of these carts were equipped with electronic benefit transfer (EBT) machines, allowing them to accept Supplemental Nutrition Assistance Program (SNAP) benefits. This article examines the association between type and quantities of fruits and vegetables purchased from mobile fruit and vegetable vendors and consumer characteristics, including payment method.
Governments worldwide recommend daily consumption of fruit and vegetables. We examine whether this benefits health in the general population of England.
Most children do not meet daily recommendations for fruit and vegetable intake, and consumption of vegetables remains especially low. Eating habits track from childhood to adulthood hence establishing liking and intake of vegetables is important.
Is consumption of fruits and vegetables with high levels of pesticide residues associated with lower semen quality?
The nightshade family Solanaceae holds exceptional economic and cultural importance. The early diversification of Solanaceae is thought to have occurred in South America during its separation from Gondwana, but the family’s sparse fossil record provides few insights. We report 52.2-million-year-old lantern fruits from terminal-Gondwanan Patagonia, featuring highly inflated, five-lobed calyces, as a newly identified species of the derived, diverse New World genus Physalis (e.g., groundcherries and tomatillos). The fossils are considerably older than corresponding molecular divergence dates and demonstrate an ancient history for the inflated calyx syndrome. The derived position of these early Eocene fossils shows that Solanaceae were well diversified long before final Gondwanan breakup.
Fruit and vegetable consumption and all-cause mortality: evidence from a large Australian cohort study

There is growing evidence for a relationship between fruit and vegetable consumption and all-cause mortality. Few studies, however, specifically explored consuming raw versus cooked vegetables in relation to health and mortality outcomes. The purpose of this study was to examine the relation of all-cause mortality with: a) fruit and vegetable consumption, either combined or separately; b) the consumption of raw versus cooked vegetables in a large cohort of Australian middle-aged and older adults.
Direct-to-consumer marketing efforts, such as community-supported agriculture (CSA), have been proposed as a solution for disparities in fruit and vegetable consumption. Evaluations of such efforts have been limited. The objective of this study was to test the feasibility of a CSA intervention to increase household inventory of fruits and vegetables and fruit and vegetable consumption of residents of an underresourced community.
Globally, fruit and vegetable intakes are well below recommendations despite ample evidence to link insufficient intake with increased risk of overweight and obesity. Intakes of fruits and vegetables in the general population differ between males and females, and although there is growing evidence of intakes in men and women during weight loss, evidence that directly compares intakes in men and women during weight loss is lacking. This study aimed to identify any differences between males and females in fruit and vegetable intakes and plasma carotenoid concentrations during weight loss, and determine whether there is a relationship between any changes in fruit and vegetable intakes and weight change in both males and females.
