“…Home-made and industrial foods were found to have medium (12•6 kJ/g) and high (18•0 kJ/g) mean energy density, respectively (29) , which corroborates previous findings that street foods are energy-dense sources of nutrients for populations worldwide (10) . Industrial wafers and biscuits presented the highest energy density (approximately 20•9 kJ/g), possibly reflecting a high sugar and fat content (30) , as previously observed in samples of street food in Dushanbe, Tajikistan (26) .…”

Street food in Eastern Europe: a perspective from an urban environment in Moldova

Street food is popular in Eastern Europe, but its diversity and nutritional value is unknown. This study aimed to characterise the street food environment in Chișinău, Moldova, including the vending sites and vendors, food availability and nutritional composition of foods and beverages. All street food vending sites (single points of sale) located in a 1-km buffer centred on the main public market were systematically selected (n=439; n=328 participants). Data on vending sites’ characteristics (mobility, type of physical setup and access to electricity), operating periods and food availability was collected. Samples of the most commonly available foods of unknown composition were collected (28 homemade; 24 industrial). Macronutrients, sodium and potassium were quantified through chemical analysis. Fruit, beverages and food other than fruit were available in 2.5%, 74.3% and 80.8% of the vending sites. Among the latter, 66.4% sold only industrial (e.g. pretzels, biscuits, wafers, chocolate and ice-cream), 21.5% only homemade (e.g. savoury and sweet pastries) and 12.1% both. Homemade foods presented larger serving sizes and energy/serving (median kcal/serving: 313.7 vs. 160.2, p=0.022); industrial foods were more energy-dense (median kcal/100g: 429.5 vs. 303.5, p=0.002). High saturated, trans-fat and sodium content was found, reaching 10.9 g/serving, 1.4 g/serving and 773.7 mg/serving, respectively. Soft drinks and alcoholic beverages were available in 80.7% and 42.0% of the vending sites selling beverages. Concluding, industrial snacks and homemade pastries high in sodium and unhealthy fat, were frequent in Chișinău. Prevention of diet-related diseases in Moldova may benefit from the improvement of the nutritional profile of street food.

“…the calories provided per gram), which is typically the result of the fibre and/or water content of the food, it is possible to consume larger overall quantities of foods (on a volume or gram basis), making it far easier to achieve nutrient requirements within calorie requirements, provided the foods chosen are rich in essential nutrients. Furthermore, there is some evidence that the larger volume of food may help to reduce hunger between meals, which could aid weight loss (Rolls ). BNF’s Quality Calorie concept illustrates that the nutritional quality of food choices, even when calorie content remains the same, can vary considerably (BNF ).…”

Proceedings of a roundtable event ‘Is communicating the concept of nutrient density important?’

et al. 2020

The British Nutrition Foundation held a 1‐day roundtable event to gather views from a wide range of stakeholders on the relevance and importance of the concept of nutrient density in supporting and motivating people to make healthier dietary choices. The opportunities and barriers associated with the use of this concept were also explored. The roundtable involved experts from research, public health nutrition, dietetics, retail and nutrition science communication, and this report describes the main themes emerging from the discussions. High obesity prevalence rates indicate that, on average, we are consuming too many calories relative to energy requirements; yet, the quality of our diets, with respect to certain vitamins and minerals and fibre, seems to be falling somewhat short of recommendations. Addressing this issue may require a more holistic approach than the current focus on restricting single nutrients prevalent in public health messaging internationally. Most members of the roundtable felt that communicating the concept of nutrient density may help in encouraging healthier food choices and dietary patterns that are higher in nutritional quality. However, while nutrient profiling has been used to guide front‐of‐pack labelling and in restricting the advertising of less healthy foods to children, there is a lack of consensus on the precise definition of a ‘nutrient dense’ food or which nutrients should be used as markers of the ‘healthiness’ of foods/drinks, and the term seems to be poorly understood by consumers and health professionals alike. Therefore, further work is required if tools around this concept are to be developed to try and successfully promote behaviour change.

“…The Slimming World dietary approach (Food Optimising R ) encourages ad libitum intake of many lower energy-dense foods and controlled amounts of higher energy-dense foods. Research suggests that dietary approaches based on the promotion of lower energy-dense foods can reduce bodyweight (Rouhani et al 2016;Stelmach-Mardas et al 2016) and promote satiety (Rolls 2017), although the efficacy of this approach to support long-term weight loss maintenance is unclear (Karl & Roberts 2014).…”

Ensuring a healthy approach to long‐term weight management: Review of the Slimming World programme

et al. 2019

Weight management programmes have been shown to be effective interventions that encourage clinically relevant weight loss. The aim of a weight management programme is not only to achieve weight loss, but also to support long‐term weight maintenance and for that reason their suitability in helping people to meet the key dietary recommendations for health must be considered. The British Nutrition Foundation was asked to investigate whether the Slimming World weight management programme is consistent with current nutrient and food‐based recommendations, and whether Slimming World members following the programme are typically eating diets meeting these recommendations in the ‘real world’. This was to help inform any potential refinements to their dietary approach. A three‐stage approach included a review of Slimming World's dietary approach resources, nutritional analysis of Slimming World's example menu plans and dietary analysis of 40 7‐day weighed food diaries completed by adult female Slimming World members. The Slimming World dietary approach reflects many of the main messages in the UK's Eatwell Guide and generally accepted healthy eating advice. Several observations were made with indications for potential changes in relation to key food groups. Nutritional analysis of the 7‐day menu plans suggests that a Slimming World member following a provided example menu plan could meet many of the UK dietary recommendations that were analysed in this review. Food diary analysis suggests the Slimming World study sample on average met dietary recommendations for total fat, saturated fat, calcium, salt and 5 A DAY. In comparison, national dietary surveys report that the average UK adult female population meets the total fat and calcium recommendations, but is not meeting the recommendations for saturated fat, salt and 5 A DAY. The study sample did not meet the recommendations for intakes of fibre and free sugars and oil‐rich fish, but these were still closer to recommendations than the average UK adult female population. High intakes of red and processed meat and alcohol were observed amongst some of the study sample. Overall, the findings suggest that despite a reduction in energy intake, adult females following this weight management programme may be consuming a diet that more closely meets UK dietary guidelines when compared with the average UK adult female population.
