(1) This study suggests that moderate drinking may influence the quit smoking process. Further study is needed to better understand the implications of moderate drinking for smoking cessation. (2) Providing information alone may not be effective in helping people abstain from drinking during smoking cessation, especially if moderate drinkers do not perceive their behavior as reducing their chance for a successful quit attempt. Tailoring smoking cessation interventions to include strategies to reduce moderate-to-heavy alcohol consumption may improve smoking cessation outcomes among alcohol users attempting to quit smoking.
Diet sustainability analyses are stronger when they incorporate multiple food systems domains, disciplines, scales, and time/space dimensions into a common modeling framework. Few analyses do this well: there are large gaps in food systems data in many regions, accessing private and some public data can be difficult, and there are analytical challenges, such as creating linkages across datasets and using complex analytical methods. This article summarizes key data sources across multiple domains of food system sustainability (nutrition, economic, environment) and describes methods and tools for integrating them into a common analytic framework. Our focus is the United States because of the large number of publicly available and highly disaggregated datasets. Thematically, we focus on linkages that exist between environmental and economic datasets to nutrition, which can be used to estimate the cost and agricultural resource use of food waste, interrelationships between healthy eating and climate impacts, diets optimized for cost, nutrition, and environmental impacts, and others. The limitations of these approaches and data sources are described next. By enhancing data integration across these fields, researchers can be better equipped to promote policy for sustainable diets.
This study assessed the impact of germination duration on two varieties of wheat grown organically (Expresso and Syngenta SY Basalt (Basalt)). In Expresso, D-glucose content increased from 0.06 g/100 g in the control to 0.55 g/100 g after a 24-h germination period (P < 0.05). In both varieties, similar increases were observed for sucrose and maltose, and no pattern emerged for resistant starch or phytate. In Basalt, baseline phytate (0 h 1.07 g/100 g) did not differ from treatment groups (6 h 0.97 g/100 g; 12 h 0.98 g/100 g; 24 h 1.09 g/100 g; 36 h 0.98 g/100 g). Functional properties of flour decreased with germination duration and resulted in bread which panellists perceived to have inferior crumb (24 h Expresso; 36 h Basalt; P < 0.05). However, there was no difference in the overall acceptability of breads across treatments and inclusion of germinated wheat improved bread sweetness.
Altering dietary patterns is essential to ameliorating the environmental impacts of the world food system. The U.S. National School Lunch Program shapes the consumption of America’s children and adolescents, providing a meaningful opportunity to reduce dietary environmental impacts. Here, we collate life cycle inventories relevant to the National School Lunch Program and assess the environmental impacts of a representative sample of lunches served in the U.S. during the 2014–2015 school year to inform school meal policy. The mean ± SE impact per lunch was 1.5 ± 0.03 kg CO2 eq. climate change, 1.8 ± 0.03 m2a crop eq. land use, 0.055 ± 0.00 m3 water consumption, and 0.24 ± 0.05 g phosphorus eq. freshwater and 3.1 ± 0.00 g nitrogen eq. marine eutrophication. Meat products contributed the most (28–67%) to total impacts for all impact categories. Lunches in the top quintile of impacts contributed an outsized proportion to total impacts (~40%) suggesting that policy changes related to these lunches should be prioritized. To reduce the environmental impacts of the National School Lunch Program, our results support increasing whole grain requirements and providing serving size or frequency limits for beef.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
