Figs are a rich source of several different minerals and fibres. We studied the effect of the consumption of dried California Mission figs on mineral and nutrient levels, as well as the effect of the addition of figs to a self-selected habitual diet on dietary patterns.

A crossover randomized controlled trial study design in which participants with a mean of age of approximately 56 years were randomly assigned to eat either their usual diet for 5 weeks or to add dried California Mission figs (120 g/d) to their usual diet for 5 weeks, after which they crossed over to the other group for an additional 5 weeks. Six 24 h dietary recalls and four blood samples were obtained from each participant.

Loma Linda University School of Public Health, USA.

A follow-up study using data collected from eighty-eight American males and females from September to December 2008.

Diets reported in the 24 h dietary recall during the fig-supplemented diet period were significantly higher in Ca and K in the dietary and total phase (P value<0·05). Nevertheless, data on mineral levels in the body gathered by means of biochemical analyses from blood samples were nearly the same for both the figs-added and the participants’ standard diet. The estimated displacement suggests that eating figs resulted in the elimination of 4 % of desserts, 5 % of vegetables, 10 % of dairy products, 23 % of grain products and 168 % of beverages from other sources that participants would otherwise consume.

Based on 24 h dietary recalls, the daily consumption of figs may increase the intake of several different minerals. However, mineral levels in blood samples were not altered significantly.

We investigated whether a higher number of fast-food outlets in an individual’s home neighbourhood is associated with increased prevalence of type 2 diabetes mellitus and related risk factors, including obesity.

Cross-sectional study.

Three UK-based diabetes screening studies (one general population, two high-risk populations) conducted between 2004 and 2011. The primary outcome was screen-detected type 2 diabetes. Secondary outcomes were risk factors for type 2 diabetes.

In total 10 461 participants (mean age 59 years; 53 % male; 21 % non-White ethnicity).

There was a higher number of neighbourhood (500 m radius from home postcode) fast-food outlets among non-White ethnic groups (P<0·001) and in socially deprived areas (P<0·001). After adjustment (social deprivation, urban/rural, ethnicity, age, sex), more fast-food outlets was associated with significantly increased odds for diabetes (OR=1·02; 95 % CI 1·00, 1·04) and obesity (OR=1·02; 95 % CI 1·00, 1·03). This suggests that for every additional two outlets per neighbourhood, we would expect one additional diabetes case, assuming a causal relationship between the fast-food outlets and diabetes.

These results suggest that increased exposure to fast-food outlets is associated with increased risk of type 2 diabetes and obesity, which has implications for diabetes prevention at a public health level and for those granting planning permission to new fast-food outlets.

Corner stores, also known as bodegas, are prevalent in low-income urban areas and primarily stock high-energy foods and beverages. Little is known about individual-level purchases in these locations. The purpose of the present study was to assess corner store purchases (items, nutritional characteristics and amount spent) made by children, adolescents and adults in a low-income urban environment.

Evaluation staff used 9238 intercept surveys to directly examine food and beverage purchases.

Intercepts were collected at 192 corner stores in Philadelphia, PA, USA.

Participants were adult, adolescent and child corner store shoppers.

Among the 9238 intercept surveys, there were 20 244 items. On average, at each corner store visit, consumers purchased 2·2 (sd 2·1) items (1·3 (sd 2·0) foods and 0·9 (sd 0·9) beverages) that cost $US 2·74 (sd $US 3·52) and contained 2786·5 (sd 4454·2) kJ (666·0 (sd 1064·6) kcal). Whether the data were examined as a percentage of total items purchased or as a percentage of intercepts, the most common corner store purchases were beverages, chips, prepared food items, pastries and candy. Beverage purchases occurred during 65·9 % of intercepts and accounted for 39·2 % of all items. Regular soda was the most popular beverage purchase. Corner store purchases averaged 66·2 g of sugar, 921·1 mg of sodium and 2·5 g of fibre per intercept. Compared with children and adolescents, adults spent the most money and purchased the most energy.

Urban corner store shoppers spent almost $US 3·00 for over 2700 kJ (650 kcal) per store visit. Obesity prevention efforts may benefit from including interventions aimed at changing corner store food environments in low-income, urban areas.
