Low-income areas in which residents have poor access to healthy foods have been referred to as "food deserts." It is thought that improving food access may help curb the obesity epidemic. Little is known about where residents of food deserts shop and if shopping habits are associated with body mass index (BMI). We evaluated the association of food shopping and acquisition (e.g., obtaining food from church, food pantries, etc.) with BMI among 459 residents of low-income communities from two South Carolina counties, 81% of whom lived in United States Department of Agriculture-designated food deserts...

BACKGROUND: Food deserts (FD), neighborhoods defined as low-income areas with low access to healthy food, are a public health concern. We evaluated the impact of living in FD on cardiovascular risk factors and subclinical cardiovascular disease (CVD) with the hypothesis that people living in FD will have an unfavorable CVD risk profile. We further assessed whether the impact of FD on these measures is driven by area income, individual household income, or area access to healthy food. METHODS AND RESULTS: We studied 1421 subjects residing in the Atlanta metropolitan area who participated in the META-Health study (Morehouse and Emory Team up to Eliminate Health Disparities; n=712) and the Predictive Health study (n=709)...

Studies of contemporary populations have demonstrated an association between decreased dietary diversity due to resource scarcity or underutilization and an increase in diseases related to poor micronutrient intake. With a reduction of dietary diversity, it is often the women and children in a population who are the first to suffer the effects of poor micronutrient status. Scurvy, a disease of prolonged vitamin C deficiency, is a micronutrient malnutrition disorder associated with resource scarcity, low dietary diversity, and/or dependence on high carbohydrate staple-foods...

Central-place foragers need to explore their immediate habitat in order to reach food. We let colonies of the individually foraging desert ant Cataglyphis niger search for a food reward in a maze. We did so for three tests per day over two successive days and an additional test after a time interval of 4-20 days (seven tests in total). We examined whether the colonies reached the food reward faster, consumed more food and changed the number of workers searching over time, within and between days. Colonies' food-discovery time shortened within and between days, indicating that some workers learnt and became more efficient in moving through the maze...

Prices affect food purchase decisions, particularly in lower-income communities, where access to a range of food retailers (including supermarkets) is limited. The aim of this study was to examine differences in staple food pricing between small urban food stores and the closest supermarkets, as well as whether pricing differentials varied based on proximity between small stores and larger retailers. In 2014, prices were measured for 15 staple foods during store visits in 140 smaller stores (corner stores, gas-marts, dollar stores, and pharmacies) in Minneapolis/St...

Degradation and alteration of natural environments because of agriculture and other land uses have major consequences on vertebrate populations, particularly on spatial organization and movement patterns. We used GPS tracking to study the effect of land use and sex on the home range size and movement of a typical model species, the Ethiopian hedgehogs. We used free-ranging hedgehogs from two areas with different land use practices: 24 from an area dominated by irrigated farms (12 ♂♂, 12 ♀♀) and 22 from a natural desert environment within a biosphere reserve (12 ♂♂, 10 ♀♀)...

The cold-active esterases are gaining importance due to their catalytic activities finding applications in chemical industry, food processes and detergent industry as additives, and organic synthesis of unstable compounds as catalysts. In the present study, the complete genome sequence of 4,843,645 bp with an average 34.08% G + C content and 4260 protein-coding genes are reported for the low temperature-active esterase-producing novel strain of Chrysobacterium isolated from the top-surface soil of a glacier in the cold deserts of the Indian trans-Himalayas...

Understanding how climatic variation affects animal populations and communities is essential for addressing threats posed by climate change, especially in systems where impacts are projected to be high. We evaluated abundance dynamics of five common species of diurnal lizards over 25 years in a Sonoran Desert transition zone where precipitation decreased and temperature increased across time, and assessed hypotheses for the influence of climatic flux on spatiotemporal variation in abundances. We repeatedly surveyed lizards in spring and summer of each year at up to 32 sites, and used hierarchical mixture models to estimate detection probabilities, abundances, and population growth rates...

PURPOSE: The purpose of this scoping review was to determine the health-equity issues that relate to childhood obesity. METHODS: Health-equity issues related to childhood obesity were identified by analyzing food environment, natural and built environment, and social environment. The authors searched Medline, PubMed, and Web of Science, using the keywords "children" and "obesity." Specific terms for each environment were added: "food desert," "advertising," "insecurity," "price," "processing," "trade," and "school" for food environment; "urban design," "land use," "transportation mode," "public facilities," and "market access" for natural and built environment; and "financial capacity/poverty," "living conditions," "transport access," "remoteness," "social support," "social cohesion," "working practices," "eating habits," "time," and "social norms" for social environment...

Improving access to healthy foods in low-income neighborhoods is a national priority. Our study evaluated the impact of opening a supermarket in a 'food desert' on healthy food access, availability and prices in the local food environment. We conducted 30 comprehensive in-store audits collecting information on healthy and unhealthy food availability, food prices and store environment, as well as 746 household surveys in two low-income neighborhoods before and after one of the two neighborhoods received a new supermarket...

BACKGROUND: Lipids are biomolecules with interesting structural variability. They are involved in many processes such as the storage of energy, in nutrition and are also of relevance for signal transduction processes, in apoptosis, cell differentiation and phagocytosis, etc. Algae and microalgae are a promising and very diverse group of organisms. These living arganisms inhabit a vaste range of ecosystems from the Antarctic to the Deserts. They account for above half the primary productivity at the base of the food chain because of their multiple nutritional products including, for instance, lipids...

Opuntia species have been used for centuries as food resources and in traditional folk medicine for their nutritional properties and their benefit in chronic diseases, particularly diabetes, obesity, cardiovascular diseases, and cancer. These plants are largely distributed in America, Africa, and the Mediterranean basin. Opuntia spp. have great economic potential because they grow in arid and desert areas, and O. ficus-indica, the domesticated O. species, is used as a nutritional and pharmaceutical agent in various dietary and value-added products...

The desert locust is an agricultural pest that is able to switch from a harmless solitarious stage during recession periods, to swarms of gregarious individuals that disperse long distances and affect areas from western Africa to India during outbreak periods. Large outbreaks have been recorded through centuries, and the Food and Agriculture Organization keeps a long-term, large-scale monitoring survey database in the area. However, there is also a much less known subspecies that occupies a limited area in southern Africa...

This study is the first to evaluate the potential of Calligonum azel Maire as a food ingredient. The plant materials flowers, leaves, stems and roots were analyzed by wet-chemical and instrumental methods for major and minor composition. The highest protein and sugar contents were recorded in the flowers (17.8% and 1.6% respectively), while the fat content was most abundant in the leaves (2.9%). Hexane extracts screened by gas chromatography (GC) for fatty acid composition showed 14 major compounds such as oleic acid, linoleic acid and palmitic acid, but also ω3 and ω6 unsaturated fatty acids...

The Arabian oryx, a moderately large mammal that inhabits a harsh desert environment, has been shown to exhibit seasonal variations in activity and inactivity patterns. Here we analyzed the continuous year-round activity patterns of twelve free-roaming Arabian oryx under natural conditions from two varying desert environments in Saudi Arabia using abdominally implanted activity meters. We simultaneously recorded weather parameters at both sites to determine whether environmental factors are responsible for temporal niche switching as well as the seasonal structuring and timing of this behavioural plasticity...

Several community level measures of healthy food access exist, but evaluation efforts have been limited leaving uncertainty about how to prioritize communities for intervention. This study aimed to assess several existing measures to inform statewide public health planning efforts in New Jersey, USA. We assessed agreement between community measures of healthy food access and then evaluated the predictive validity of each measure by describing its association with complete fruit and vegetable cash-value voucher redemption (proportion redeemed ≥70, ≥80, ≥90%) among 30,078 low-income households participating in the New Jersey Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) during 2013-2014...

Food availability significantly affects an animal's energy metabolism, and thus its phenotype, survival, and reproduction. Maternal and offspring responses to food conditions are critical for understanding population dynamics and life-history evolution of a species. In this study, we conducted food manipulation experiments in field enclosures to identify the effect of food restriction on female reproductive traits and postpartum body condition, as well as on hatchling phenotypes, in a lacertid viviparous lizard from the Inner Mongolian desert steppe of China...

BACKGROUND: Improving access to supermarkets has been shown to improve some dietary outcomes, yet there is little evidence for such effects on children. Relatedly, there is a dearth of research assessing the impact of a structural change (i.e. supermarket in a former food desert) on the home environment and its relationship with children's diet. OBJECTIVE: Assess the relative impact of the home environment on children's diet after the introduction of a new supermarket in a food desert...

Interventions to address diet, a modifiable risk factor for diabetes, cancer, and cardiovascular disease, have increasingly emphasized the influence of the physical environment on diet, while more traditional approaches have focused on individual characteristics. We examined environmental and individual influences on diet to understand the role of both. Household interviews were conducted in 2011 with 1372 individuals randomly selected from two low-income, predominantly African American neighborhoods in Pittsburgh, PA...
