To investigate the effects of a sugar-sweetened beverage (SSB) tax and a nutrient profiling tax on consumer food purchases in a virtual supermarket.

A randomised controlled trial was conducted with a control condition with regular food prices (n 152), an SSB tax condition (n 130) and a nutrient profiling tax condition based on Nutri-Score (n 112). Participants completed a weekly grocery shop for their household. Primary outcome measures were SSB purchases (ordinal variable) and the overall healthiness of the total shopping basket (proportion of total unit food items classified as healthy). The secondary outcome measure was the energy (kcal) content of the total shopping basket. Data were analysed using regression analyses.

Three-dimensional virtual supermarket.

Dutch adults aged ≥18 years are being responsible for grocery shopping in their household (n 394).

The SSB tax (OR = 1·62, (95 % CI 1·03, 2·54)) and the nutrient profiling tax (OR = 1·88, (95 %CI 1·17, 3·02)) increased the likelihood of being in a lower-level category of SSB purchases. The overall healthiness of the total shopping basket was higher (+2·7 percent point, (95 % CI 0·1, 5·3)), and the energy content was lower (−3301 kcal, (95 % CI −6425, −177)) for participants in the nutrient profiling tax condition than for those in the control condition. The SSB tax did not affect the overall healthiness and energy content of the total shopping basket (P > 0·05).

A nutrient profiling tax targeting a wide range of foods and beverages with a low nutritional quality seems to have larger beneficial effects on consumer food purchases than taxation of SSB alone.

To evaluate the effectiveness of PASOS SALUDABLES, a culturally tailored lifestyle intervention to prevent obesity and diabetes among Latino farmworkers, when implemented at large scale in the worksite.

This study was a two-arm parallel group, cluster randomised controlled trial, where participants received either a twelve-session lifestyle intervention (intervention) or six-session leadership training (control) at their worksite. The intervention was delivered by Promotoras in Spanish. All sessions were conducted at the worksites (ranches) during meal breaks. Blinded, trained research assistants collected socio-demographic and outcome data (i.e. BMI as primary outcome and waist circumference, glycated Hb (HbA1c), cholesterol and blood pressure as secondary outcomes) at baseline and follow-up assessments (i.e. 3 months, 6 months, 1 year and 1·5 years).

Recruitment and intervention delivery occurred at twelve study ranches in Oxnard, California.

We enrolled farmworkers hired by a large berry grower company, who were ≥18 years old, spoke Spanish and were free of diabetes at screening.

A total of 344 workers were enrolled in the intervention and 271 in the control group. The intervention resulted in attenuated increase of BMI over time; however, the difference in trend between groups was not significant (β = −0·01 for slope difference, P = 0·29). No significantly different trend by group was observed in secondary outcomes (P > 0·27).

The worksite intervention, implemented during meal breaks, did not reduce BMI or other clinical indicators. Nevertheless, this study supports the feasibility of recruiting and engaging the Latino farmworker population in workplace health promotion interventions.

To identify food purchase patterns and to assess their carbon footprint and expenditure.

Cross-sectional.

Purchase patterns were identified by factor analysis from the annual purchases of 3435 product groups. The associations between purchase patterns and the total purchases’ carbon footprints (based on life-cycle assessment) and expenditure were analysed using linear regression and adjusted for nutritional energy content of the purchases.

Loyalty card holders (n 22 860) of the largest food retailer in Finland.

Eight patterns explained 55 % of the variation in food purchases. The Animal-based pattern made the greatest contribution to the annual carbon footprint, followed by the Easy-cooking, and Ready-to-eat patterns. High-energy, Traditional and Plant-based patterns made the smallest contribution to the carbon footprint of the purchases. Animal-based, Ready-to-eat, Plant-based and High-energy patterns made the greatest contribution, whereas the Traditional and Easy-cooking patterns made the smallest contribution to food expenditure. Carbon footprint per euros spent increased with stronger adherence to the Traditional, Animal-based and Easy-cooking patterns.

The Animal-based, Ready-to-eat and High-energy patterns were associated with relatively high expenditure on food, suggesting no economic barrier to a potential shift towards a plant-based diet for consumers adherent to those patterns. Strong adherence to the Traditional pattern resulted in a low energy-adjusted carbon footprint but high carbon footprint per euro. This suggests a preference for cheap nutritional energy rather than environment-conscious purchase behaviour. Whether a shift towards a plant-based pattern would be affordable for those with more traditional and cheaper purchase patterns requires more research.

The involvement of unhealthy commodity corporations in health policy and research has been identified as an important commercial determinant contributing to the rise of non-communicable diseases. In the USA, health professional associations have been subject to corporate influence. This study explores the interactions between corporations and the Academy of Nutrition and Dietetics (AND), and their implications for the profession in the USA and globally.

We conducted an inductive analysis of documents (2014–2020) obtained through freedom of information requests, to assess key AND actors’ dealings with food, pharmaceutical and agribusiness corporations. We also triangulated this information with publicly available data.

Not applicable.

The AND, AND Foundation (ANDF) and its key leaders have ongoing interactions with corporations. These include AND’s leaders holding key positions in multinational food, pharmaceutical or agribusiness corporations, and AND accepting corporate financial contributions. We found the AND has invested funds in corporations such as Nestlé, PepsiCo and pharmaceutical companies, has discussed internal policies to fit industry needs and has had public positions favouring corporations.

The documents reveal a symbiotic relationship between the AND, its Foundation and corporations. Corporations assist the AND and ANDF with financial contributions. AND acts as a pro-industry voice in some policy venues, and with public positions that clash with AND’s mission to improve health globally.

The most important risk factor of cardiovascular disease is hypertension and high salt intake contributes to high blood pressure. However, to prevent iodine deficiency disorders, the iodisation of salt is a proven strategy. So, on one hand, we suggest people reduced salt consumption but on the other hand, we also fear an increase in the prevalence of iodine deficiency disorders. In the present study, we investigated the possibility of salt intake at WHO recommended levels resulting in higher or lower iodine status in India by assessing the urinary iodine status and its relation with blood pressure.

It was a cross-sectional study.

It was a community-based study.

We collected 24-hour urine samples for estimation of iodine concentrations in urine from 411 adult hypertensives in the Mandla district of central India. Urinary iodine was estimated using Thermo ORION make ion-selective electrodes.

The median urinary iodine excretion was 162·6 mcg/l. Interestingly 371 (90·26 %) subjects were observed with > 200 mcg/l urinary iodine concentration level indicating iodine sufficiency. Individuals with high urine Na significantly had high blood pressure as compared with individuals with low urinary Na excretion (P < 0·01). There is a higher probability of high urine iodine levels among individuals with higher urine Na levels.

The study revealed that 90 % of the population were excreting excessive iodine in urine, which is more than adequate iodine uptake. This excess uptake enables a scope for reduction in salt intake to control hypertension.

This study aimed to identify individual and contextual factors that are associated with under- and over-nutrition among school-aged children and adolescents in two Nigerian states.

Community-based cross-sectional study.

The study was carried out in rural and urban communities of Osun and Gombe States in Nigeria.

A total of 1200 school-aged children and adolescents.

Multi-level analysis showed that the full models accounted for about 82 % and 39 % of the odds of thinness or overweight/obese across the communities, respectively. Household size (adjusted OR (aOR) 1·10; P = 0·001; 95 % CI (1·04, 1·16)) increased the odds, while the upper wealth index (aOR 0·43; P = 0·016; 95 % CI (0·22, 0·86)) decreased the odds of thinness. Age (aOR 0·86; P < 0·001; 95 % CI (1·26, 8·70)), exclusive breastfeeding (aOR 0·46; P = 0·010; 95 % CI (0·25, 0·83)), physical activity (aOR 0·55; P = 0·001; 95 % CI (0·39, 0·78)) and the upper wealth index (aOR 0·47; P = 0·018; 95 % CI (0·25, 0·88)) were inversely related with overweight/obesity, while residing in Osun State (aOR 3·32; P = 0·015; 95 % CI (1·26, 1·70)), female gender (aOR 1·73; P = 0·015; 95 % CI (1·11, 2·69)) and screen time > 2 h/d (aOR 2·33; P = 0·005; 95 % CI (1·29, 4·19)) were positively associated with overweight/obesity.

The study shows that selected community and individual-level factors are strongly associated with thinness and overweight/obesity among school-aged children and adolescents.

Eating a variety of nutritious foods is fundamental to good nutrition. However, this principle is challenged when recommendations seeking to improve the environmental sustainability of diets call for avoidance of foods considered to have a higher environmental footprint, such as animal-sourced foods. Our objective was to assess the implications for nutritional adequacy of protein choice across Australian adult diets preselected as having higher quality and lower environmental impact scores.

Each individual diet was assessed for variety of food choice within the ‘Fresh meat and alternatives’ food group defined in the Australian Dietary Guidelines, which includes protein-rich foods such as eggs, nuts, tofu and legumes in addition to animal meats. Diets were grouped according to variety score and whether they included only animal meats, only alternatives or a variety of meat and alternatives. Nutrient content was assessed relative to estimated average requirements (EAR).

Australia.

1700 adults participating in the Australian Health Survey

For diets with higher diet quality and lower environmental impact, the likelihood of achieving nutrient EAR significantly increased as variety of food choice in the ‘Fresh meat and alternatives’ food group increased (P < 0·001). Variety score and number of serves were also correlated (r = 0·52, P < 0·001) which is relevant since most diets did not meet the recommended minimum number of serves for this food group.

Greater variety within the ‘Fresh meat and alternatives’ food group is beneficial to meeting EAR and lower environmental impact diets can include three or more selections including foods of animal origin.
