Project description:Limited research has examined the impact of energy labelling on portion size selection. It is also unclear whether physical activity calorie equivalent (PACE) is more effective than standard kilocalorie (kcal) energy labelling in promoting healthier dietary behaviour and whether effectiveness varies based on socioeconomic position (SEP). In the present online study, 1667 UK adults of lower and higher SEP made virtual portion size selections for 18 common main meal foods under one of four conditions: kcal labelling only, PACE labelling only, kcal and PACE labelling, no labelling. Contrary to predictions, participants in the kcal labelling condition (+55 kcal, p < 0.001) chose larger portion sizes compared to the no labelling condition, whereas the PACE labelling (-17 kcal, p = 0.065) and no labelling condition did not significantly differ. The presence of PACE information on labels was associated with selection of significantly smaller portions when compared to labels that only included kcal information. Effects of labels on portion size selection were not moderated by participant SEP in primary analyses. The present study of virtual portion size selections suggests that kcal labelling resulted in larger portion size selections than no labelling, but this counter-intuitive effect was attenuated when kcal and PACE labelling were combined. Further research examining the impact of PACE labelling on real-world food selection in participants of lower and higher SEP is now warranted.

Project description:India is undergoing a shift in consumption from traditional foods to processed foods high in sugar, salt and fat. Partially hydrogenated vegetable oils (PHVOs) high in trans-fat are often used in processed foods in India given their low cost and extended shelf life. The World Health Organization has called for the elimination of PHVOs from the global food supply and recommends their replacement with polyunsaturated fat to maximize health benefits. This study examined barriers to replacing industrially produced trans-fat in the Indian food supply and systematically identified potential policy solutions to assist the government in encouraging its removal and replacement with healthier polyunsaturated fat. A combination of food supply chain analysis and semi-structured interviews with key stakeholders was conducted. The main barriers faced by the food-processing sector in terms of reducing use of trans-fat and replacing it with healthier oils in India were the low availability and high cost of oils high in polyunsaturated fats leading to a reliance on palm oil (high in saturated fat) and the low use of those healthier oils in product reformulation. Improved integration between farmers and processors, investment in technology and pricing strategies to incentivize use of healthier oils for product reformulation were identified as policy options. Food processors have trouble accessing sufficient affordable healthy oils for product reformulation, but existing incentives aimed at supporting food processing could be tweaked to ensure a greater supply of healthy oils with the potential to improve population health.

Project description:BackgroundOn 6 April 2022, legislation came into effect in England requiring calorie labels to be applied to food items on menus of larger food businesses. This study aimed to assess the impact of calorie labelling on (a) food purchased and (b) energy content of menu options in worksite cafeterias.MethodsProduct-level sales data and energy content of available items was obtained from 142 worksite cafeterias from January 2022-October 2022. Interrupted-time-series (ITS) analysis with level and slope change evaluated daily energy (kcal) purchased per item, and ITS with level change assessed mean energy per option available on menus before and after calorie labelling. Each analysis was conducted 6 weeks and 6 months from implementation. A post-hoc ITS examined weekly energy purchased per item over a longer period (March 2021-October 2022; 135 sites).ResultsThere was no evidence calorie labelling changed the energy content of foods purchased (6-week: + 0.60 cal/product, 95%CI:-2.54, + 3.75; 6-month: + 1.59 cal/product, 95%CI:-0.96, + 4.16). Post-hoc analyses suggested calorie labels were associated with a reduction in mean energy of items purchased over time (-0.65 kcal/week, 95%CI:-0.81,-0.49), but a significant increase (+ 3 kcal, 95%CI: + 0.43, + 5.60) at the point of implementation. There was a reduction in the mean energy content of menu options at each seasonal menu change (April 2022:-1.79 kcal, 95%CI:-3.42,-0.15; July 2022:-4.18 kcal, 95% CI:-7.65,-0.73).ConclusionThis large observational study in worksite cafeterias found no evidence to indicate the introduction of calorie labelling led to any immediate reduction in energy purchased by customers. There was some evidence of increasing impact over time, possibly associated with changes in menu offerings, but this effect was small and cannot be directly attributed to calorie labelling.

Project description:Children frequently consume beverages that are either sweetened with sugars (sugar-sweetened beverages; SSB) or low-calorie sweeteners (LCS). Here, we evaluated the effects of habitual early life consumption of either SSB or LCS on energy balance later during adulthood. Male and female rats were provided with chow, water, and a solution containing either SSB (sucrose), LCS (acesulfame potassium (ACE-K) or stevia), or control (no solution) during the juvenile and adolescent periods (postnatal days 26-70). SSB or LCS consumption was voluntary and restricted within the recommended federal daily limits. When subsequently maintained on a cafeteria-style junk food diet (CAF; various high-fat, high-sugar foods) during adulthood, ACE-K-exposed rats demonstrated reduced caloric consumption vs. the controls, which contributed to lower body weights in female, but not male, ACE-K rats. These discrepant intakes and body weight effects in male ACE-K rats are likely to be based on reduced gene expression of thermogenic indicators (UCP1, BMP8B) in brown adipose tissue. Female stevia-exposed rats did not differ from the controls in terms of caloric intake or body weight, yet they consumed more SSB during CAF exposure in adulthood. None of the SSB-exposed rats, neither male nor female, differed from the controls in terms of total adult caloric consumption or body weight measures. The collective results reveal that early life LCS consumption alters sugar preference, body weight, and gene expression for markers of thermogenesis during adulthood, with both sex- and sweetener-dependent effects.

Project description:India's experience presents a puzzle at odds with a basic fact of household economics: amidst unprecedented economic growth, average per capita daily calorie consumption has declined in recent decades. Does an improving disease environment explain the calorie decline? A diminished burden of infectious disease could lower energy needs by increasing absorption and effective use of calories. We document a robust effect of disease exposure - measured as infant mortality and as poor sanitation - on calorie consumption. Similar effects are found using multiple datasets and empirical strategies. Disease can account for an important fraction (one-fifth or more) of India's calorie decline.

Project description:Food consumption is critical for animal survival and reproduction. The biomedical and economic consequences of metabolic diseases arising from excessive food intake, however, are a burden for human society. While the role of neuroendocrine feedback loops, food sensing modalities, and physiological state in regulating food intake are increasingly well understood, other genetic mechanisms remain elusive. Here, we applied ten generations of artificial selection for high and low food consumption in replicate populations of Drosophila melanogaster. The phenotypic response to selection was highly asymmetric, with efficient selection and an average realized heritability of 0.15 in the lines selected for high food consumption. To further nominate candidate genes contributing to response to selection for feeding behavior, we evaluated differences in genome wide gene expression between the selection lines using whole-fly RNA sequencing. We identified 1,631 differentially expressed genes in the analysis pooled across sexes, and 1,267 (2,321) differentially expressed genes in females (males).

Project description:The global surges in obesity and nutrition-related non-communicable diseases (NCDs) have created a need for decisive new food policy initiatives. A major concern has been the impact of ultra-processed foods (UPFs) and ultra-processed drinks on weight gain and on the risk of several NCDs. These foods, generally high in calories, added sugar, sodium, and unhealthy fats, and poor in fibre, protein, and micronutrients, have extensive negative effects on human health and on the environment (due to their associated carbon emission and water use). There is a growing tendency worldwide, and especially in South America, for food companies to add micronutrients to UPFs to make health claims regarding these products, to which food-regulating authorities refer to fake foods. Although more than 45 countries and smaller subregional or urban entities have created taxes on ultra-processed drinks, such as sugar-sweetened beverages, only a few have adopted taxes on snacks and other UPFs, and none have added major subsidies for truly healthy, fresh or minimally processed food for people from lower socioeconomic backgrounds. Another major focus has been on developing effective package labelling. A smaller number of countries have selected the most impactful warning labels and linked them with other measures to create a mutually reinforcing set of policies; a few other countries have developed effective school food policies. We herein present in-depth results from key countries involved in all these actions and in comprehensive marketing controls, and conclude with our recommendations for the future. This field is quite new; progress to date is substantial, but much more is left to learn.
