Background: Consumers are increasingly interested in environmentally sustainable dietary patterns. However, specific signals (e.g., language, labels, logos, or packaging) American consumers use to identify environmentally sustainable products are yet to be explored.
Objectives: To determine perception and preferences for environmentally sustainable food and associated health and demographic factors associated with consumers' use of signals for environmentally sustainable food products in a nationally representative survey of United States consumers.
Methods: Repeated cross-sectional data were collected for the 2019 and 2020 annual online Food and Health Survey by the International Food Information Council. Three questions were analyzed: 1) the stated importance of environmentally sustainable food products, 2) signals consumers use to identify environmentally sustainable food/beverage products, and 3) the impact of environmental sustainability on food/beverage purchase decisions. Questions 2 and 3 were asked only from participants who stated environmental sustainability is important in question 1. Options provided for signals for environmentally sustainable products were recyclable packaging, minimal packaging, labeled organic, labeled locally grown, labeled sustainably sourced, and labeled non-genetically modified organisms (GMOs)/not bioengineered. Poisson regression and logistic regressions were performed to assess associations.
Results: Of 1905 completers, 1059 (55.6%) answered that it was somewhat or very important that food products purchased/consumed were environmentally sustainable. Of those, 94% used ≥1 of the 6 signals to determine environmental sustainability when shopping. Some signals were selected despite little association with environmental sustainability (e.g., locally grown and non-GMO/not bioengineered). The number of signals consumers used was associated with education, race/ethnicity, health status, and the level of impact they reported that sustainability plays in their decisions. Associations between consumer characteristics and the use of different signals for environmental sustainability were heterogeneous.
Conclusions: Even among consumers who value environmental sustainability in food products, specific signals used by different respondents varied across demographics and health characteristics.

Platelet aggregation and inflammation play a crucial role in atherothrombosis. Wine contains micro-constituents of proper quality and quantity that exert cardioprotective actions, partly through inhibiting platelet-activating factor (PAF), a potent inflammatory and thrombotic lipid mediator. However, wine cannot be consumed extensively due to the presence of ethanol.

The use of biological control agents is one of the best strategies available to combat the plant diseases in an ecofriendly manner. Biocontrol bacteria capable of providing beneficial effect in crop plant growth and health, have been developed for several decades. It highlights the need for a deeper understanding of the colonization mechanisms employed by biocontrol bacteria to enhance their efficacy in plant pathogen control.

This paper examines the motivations and experiences of older French-speaking men who relocate to Thailand driven by the desire for a more fulfilling and liberated lifestyle that contrasts with their experiences in their home countries. Through an analysis of video interviews with 31 expatriates available online, the study reveals a prevalent trend among these men to initially engage in short-term sexual relationships, enjoying the freedoms of Thailand's vibrant social scene. However, as they acclimate to their new environment, a significant shift towards long-term partnerships is observed, marking a transition from transient interactions to more meaningful connections.

The contribution of health care to environmental and climate crises is significant, under-addressed, and with consequences for human health. This editorial is a call to action. Focusing on pharmaceuticals as a major environmental threat, we examine pharmaceutical impacts across their lifecycle, summarising greenhouse gas emissions, pollution, and biodiversity loss, and outlining challenges and opportunities to reduce this impact.

The environmental impact of chemicals used in aquaculture, particularly nitrofurantoin, has raised global concern. Nitrofurantoin, a broad-spectrum antimicrobial, is commonly used in aquaculture despite safety risks. Determination of nitrofurantoin in water samples of fish ponds is necessary to ensure the safety and quality of seafood.
