Nutritional profile of plant-based dairy alternatives in the Swedish market.

The market for plant-based dairy alternatives is growing; therefore, focusing on the nutritional quality of these products is important. This study evaluates the nutritional profile of plant-based alternatives to milk, yoghurt, cheese, cream, ice cream and fat spread in the Swedish market and compares them to corresponding dairy products. The nutritional quality of organic vs non-organic and plain vs flavoured plant-based milk and yoghurt alternatives was also assessed. Nutritional data for 222 plant-based dairy alternatives were collected from the manufacturers' websites, and data for corresponding dairy products were obtained from the Swedish Food Composition Database. Plant-based dairy alternatives had higher fibre content than dairy products, while their protein content was lower, except for soy-based products. The saturated fat content of plant-based dairy alternatives was similar to or lower than dairy products, except for coconut-based yoghurt and plant-fat-based cheese. Their energy content was also similar to or lower than dairy products, except for coconut-based yoghurt, plant-based fat spread and plant-based ice cream, which contained higher energy than yoghurt, blended margarine, and ice cream, respectively. The micronutrient fortification was mainly in plant-based milk, yoghurt, and cheese alternatives; thus, compared to dairy, they had similar or higher vitamins D, B2, and B12 (except in plant-based milk alternatives), calcium and iodine content. Furthermore, organic plant-based milk and yoghurt alternatives had a lower micronutrient content (e.g., vitamins B2 and B12, iodine and calcium) except for vitamin D than non-organic varieties. Flavoured plant-based milk and yoghurt alternatives were higher in energy and total sugar than plain varieties. In summary, plant-based dairy alternatives have nutritional strengths and weaknesses compared to dairy products that should be considered when replacing dairy.

Nutritional assessment of plant-based meat analogues on the Swedish market.

Nutritional quality of 142 plant-based meat analogues (PBMAs) on the Swedish market were assessed by nutritional contribution (NC) to recommended nutrient intake, three labelling systems (Keyhole, Nutri-Score, nutrition claims) and comparisons to meat references. Based on median (min-max) NC for macronutrients, PBMAs in general appeared as healthy options to meat due to higher NC per 100 g for fibre [PBMAs: 15% (1-33%) vs meat: 0% (0-2%)] and lower NC for saturated fat [PBMAs: 4% (0-59%) vs meat: 15% (1-51%)]. The NC per 100 g for salt was substantial for both PBMAs [25% (5-52%)] and meat [24% (2-55%)]. Limited data for micronutrients indicated that PBMAs are higher in iron compared to meat. Nutrition quality varied both between and within product categories. Mince, bite/fillet and nugget analogues were the main healthier categories, according to labelling systems. Bioavailability of iron, protein quality and effects of processing are important future aspects to consider.

Challenges for Upcycled Foods: Definition, Inclusion in the Food Waste Management Hierarchy and Public Acceptability.

Upcycled foods contain unmarketable ingredients (e.g., damaged food produce, by-products and scraps from food preparation) that otherwise would not be directed for human consumption. Upcycled food is a new food category and thus faces several challenges, such as definition development, inclusion in the food waste management hierarchy and public acceptability. This review provides an overview of these three challenges. The upcycled food definitions have been developed for research, food manufacturers, and multi-stakeholders use. Thus, there is a need for a consumer-friendly definition for the general public. A simplified definition is proposed to introduce these foods as environmentally friendly foods containing safe ingredients that otherwise would not have gone to human consumption such as damaged food produce, by-products and scraps from food preparation. Moreover, an updated version of the food waste management hierarchy has been proposed by including the production of upcycled foods as a separate waste management action that is less preferable than redistribution but more favourable than producing animal feed. Furthermore, consumer sociodemographic characteristics and beliefs, as well as food quality cues and attributes, were identified as crucial factors for the public acceptability of these foods. Future research should address these challenges to facilitate the introduction of upcycled foods.

Changes in Added Sugar Intake and Body Weight in a Cohort of Older Australians: A Secondary Analysis of the Blue Mountains Eye Study.

Background: The evidence regarding the association between added sugar (AS) intake and obesity remains inconsistent. The aim of this study was to investigate the association between changes in the percentage of energy intake from AS (EAS%) and changes in body weight in a cohort study of older Australians during 15 years of follow-up. In addition, associations were assessed according to whether EAS% intake was provided from beverage or non-beverage sources. Methods: Data were analyzed from the participants of the Blue Mountains Eye Study Cohort. Dietary data were collected at baseline (1992-94) and three five-yearly intervals using a 145-item food frequency questionnaire. Participants' body weight was measured at each time point. Five-yearly changes in EAS% intake and body weight were calculated (n = 1,713 at baseline). A generalized estimating equation (GEE) model was used to examine the relationship between the overall five-yearly changes in EAS% intake and body weight, adjusted for dietary and lifestyle variables. Results: In each time interval, the EAS% intake decreased by ~5% in the lowest quartile (Q1) and increased by ~5% in the highest quartile (Q4). The mean (SD) body weight change in Q1 and Q4 were 1.24 (8.10) kg and 1.57 (7.50) kg (first time interval), 0.08 (6.86) kg and -0.19 (5.63) kg (second time interval), and -1.22 (5.16) kg and -0.37 (5.47) kg (third time interval), respectively. In GEE analyses, the overall five-yearly change in EAS% intake was not significantly associated with body weight change (P trend = 0.837). Furthermore, no significant associations were observed between changes in EAS% intake from either beverage or non-beverage sources and changes in body weight (P trend for beverage sources = 0.621 and P trend for non-beverage sources = 0.626). Conclusion: The findings of this older Australian cohort do not support the association between changes in EAS% intake and body weight, regardless of AS food sources (beverage or non-beverage).

Pattern of omega-3 polyunsaturated fatty acid intake and fish consumption and retinal vascular caliber in children and adolescents: A cohort study.

We aimed to investigate whether fish and long chain omega-3 polyunsaturated fatty acid (LCn-3 PUFA) consumption changed appreciably during adolescence. We also assessed whether these dietary variables are associated with retinal microvascular signs (possible markers of future cardiovascular disease risk). 633 children had dietary data at ages 12 and 17. Fish and LCn-3 PUFA [eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA)] intake was assessed by a food frequency questionnaire. Retinal vessel caliber was quantified from digital photographs using computer software. Mean energy-adjusted intakes (mg/day) of total LCn-3 PUFA, EPA, and DHA at age 12 were 297.1±261.1; 102.5±106.9; and 129.7±137.7, respectively; and this increased significantly at age 17 to: 347.0±324.0 (p<0.0001); 122.5±132.7 (p = 0.0001); and 160.3±171.4 (p <0.0001), respectively. Increasing quartiles of LCn-3PUFA intake were associated with widening of mean retinal arteriolar caliber among 17-year old girls ~3.9 µm (multivariable-adjusted P-trend = 0.001). Girls who consumed ≥2 serves of fish/week versus those who did not had ~2.1 µm wider retinal arterioles (p = 0.03). No associations were observed among boys or with retinal venules. Mean dietary intakes of LCn-3 PUFA increased during adolescence, but are still below recommended levels of consumption. These results suggest that LCn-3 PUFA and fish intake might have a beneficial influence.

Added sugar intake that exceeds current recommendations is associated with nutrient dilution in older Australians.

OBJECTIVES: A nutrient dilution effect of diets high in added sugar has been reported in some older populations, but the evidence is inconsistent. The aim of this study was to investigate the association between added sugar intakes (according to recommended guidelines) and nutrient intake, food consumption, and body mass index (BMI). METHODS: A cross-sectional analysis of data collected between 2007 and 2009 from participants of the Blue Mountains Eye study 4 was performed (n = 879). Dietary intake was assessed using a semiquantitative food frequency questionnaire. Added sugar content of foods was determined by applying a systematic step-wise method. BMI was calculated from measured weight and height. Food and nutrient intakes and BMI were assessed according to categories of percentage energy from added sugar (EAS% < 5%, EAS% = 5%-10%, and EAS% >10%) using analysis of covariance for multivariate analysis. RESULTS: Micronutrient intake including retinol equivalents, vitamins B6, B12, C, E, and D, and minerals including calcium, iron, and magnesium showed a significant inverse association with EAS% intakes (Ptrend < 0.05). In people with the lowest intake of added sugars (<5% energy) intake of alcohol, fruits, and vegetables were higher and intake of sugar sweetened beverages was lower compared to other participants (all Ptrend < 0.001). BMI was similar between the three EAS% categories. CONCLUSIONS: Energy intake from added sugar greater than the recommended level of 10% is associated with lower micronutrient intakes, indicating micronutrient dilution. Conversely, added sugar intakes <5% of energy intake are associated with higher micronutrient intakes. This information may inform dietary messages targeted at optimizing diet quality in older adults.

Intake and sources of added sugars among Australian children and adolescents.

PURPOSE: To examine the intake and sources of added sugars (AS) of Australian children and adolescents, and compare their intake of free sugars (FS) to the recommended limit set by the World Health Organization (<10 % energy from FS). METHOD: Data of 4140 children and adolescents aged 2-16 years with plausible intakes based on 2 × 24 h recalls from the 2007 Australian National Children Nutrition and Physical Activity Survey were used. AS content of foods was estimated based on a published method. Intakes of AS and FS, as well as food sources of AS, were calculated. One-way ANOVA was used for comparisons between age groups and gender. RESULTS: The mean (SD) AS intake was 58.9 (35.1) g/day, representing 11.9 (5.6) % of daily energy intake and 46.9 (17.5) % of daily total sugars intake. More than 80 % of the subjects had % energy from FS > 10 %. Significant increasing trends for AS intake, % energy from AS, % energy from FS across age groups were observed. Sugar-sweetened beverages (19.6 %), cakes, biscuits, pastries and batter-based products (14.3 %), and sugar and sweet spreads (10.5 %) were the top three contributors of AS intake in the whole sample. Higher contribution of AS from sugar-sweetened beverages was observed in adolescents (p trend < 0.001). CONCLUSIONS: A large proportion of Australian youths are consuming excessive amounts of energy from AS. Since the main sources of AS were energy-dense, nutrient-poor foods, interventions which target the reduction in these foods would reduce energy and AS intake with minimal impact to core nutrient intake.
