The nutritional profile of plant-based meat analogues available for sale in Australia
Publisher: Wiley
Date: 18-01-2023
Abstract: To assess the nutritional quality of plant‐based meat analogues in Australia, compared to equivalent meat products, and to assess levels of micronutrient fortification in meat analogues. This cross‐sectional study used nutrition composition data for products collected in 2021 from major supermarkets in Australia. Nutritional quality was assessed using the Health Star Rating, energy (kJ), protein (g), saturated fat (g), sodium (mg), total sugars (g), and fibre content (g) per 100 g, and level of food processing using the NOVA classification. Proportion of products fortified with iron, vitamin B 12 and zinc were reported. Differences in health star rating and nutrients between food categories were assessed using independent t ‐tests. Seven hundred ninety products ( n = 132 plant‐based and n = 658 meat) across eight food categories were analysed. Meat analogues had a higher health star rating (mean 1.2 stars, [95% CI: 1.0–1.4 stars], p 0.001), lower mean saturated fat (−2.4 g/100 g, [−2.9 to −1.8 g/100 g], p 0.001) and sodium content (−132 mg/100 g, [−186 to −79 mg/100 g], p 0.001), but higher total sugar content (0.7 g/100 g, [0.4–1.1 g/100 g], p 0.001). Meat analogues and meat products had a similar proportion of ultra‐processed products (84% and 89%, respectively). 12.1% of meat analogues were fortified with iron, vitamin B 12 and zinc. Meat analogues generally had a higher health star rating compared with meat equivalents, however, the nutrient content varied. Most meat analogues were also ultra‐processed and few are fortified with key micronutrients found in meat. More research is needed to understand the health impact of these foods.
Eating disorder risk during behavioral weight management in adults with overweight or obesity: A systematic review with meta‐analysis
Publisher: Wiley
Date: 15-03-2023
DOI: 10.1111/OBR.13561
Abstract: This systematic review examined change in eating disorder risk during weight management interventions. Four databases and clinical trials registries were searched in March and May 2022, respectively, to identify behavioral weight management intervention trials in adults with overweight/obesity measuring eating disorder symptoms at pre‐ and post‐intervention or follow‐up. Random effects meta‐analyses were conducted examining within group change in risk. Of 12,023 screened, 49 were eligible ( n = 6337, mean age range 22.1 to 59.9 years, mean (SD) 81(20.4)% female). Interventions ranged from 4 weeks to 18 months, with follow‐up of 10 weeks to 36 months post‐intervention. There was a within group reduction in global eating disorder scores (20 intervention arms Hedges' g = −0.27 95% CI −0.36, −0.17 I 2 67.1%) and binge eating (49 intervention arms −0.66 95% CI −0.76, −0.56 I 2 82.7%) post‐intervention, both maintained at follow‐up. Of 14 studies reporting prevalence or episodes of binge eating, all reported a reduction. Four studies reported eating disorder symptoms, not present at baseline, in a subset of participants (0%–6.5%). Overall, behavioral weight management interventions do not increase eating disorder symptoms for most adults indeed, a modest reduction is seen post‐intervention and follow‐up. A small subset of participants may experience disordered eating therefore, monitoring for the emergence of symptoms is important.
Effects of Nutritional Interventions on Cardiovascular Disease Health Outcomes in Aboriginal and Torres Strait Islander Australians: A Scoping Review
Publisher: MDPI AG
Date: 15-11-2021
DOI: 10.3390/NU13114084
Abstract: Nutrition interventions can support Aboriginal and Torres Strait Islander peoples to reduce their risk of cardiovascular disease (CVD). This review examines nutritional interventions aiming to improve CVD outcomes and appraises peer-reviewed interventions using an Aboriginal and Torres Strait Islander Quality Appraisal Tool. Five electronic databases and grey literature were searched, applying no time limit. Two reviewers completed the screening, data extraction and quality assessment independently. The study quality was assessed using the South Australian Health and Medical Research Institute and the Centre of Research Excellence in Aboriginal Chronic Disease Knowledge Translation and Exchange Aboriginal and Torres Strait Islander Quality Appraisal Tool (QAT). Twenty-one nutrition programs were included in this review. Twelve reported on anthropometric measurements, ten on biochemical and/or hematological measurements and sixteen on other outcome domains. Most programs reported improvements in measurable CVD risk factors, including reduced body mass index (BMI), waist circumference (WC), weight, blood pressure and improved lipid profiles. Most programs performed well at community engagement and capacity strengthening, but many lacked the inclusion of Indigenous research paradigms, governance and strengths-based approaches. This review highlights the need for contemporary nutrition programs aimed at improving cardiovascular health outcomes to include additional key cultural components.
