   “Organic certification is a certification process for producers of organic food and other organic agricultural products. In general, any business directly involved in food production can be certified, including seed suppliers, farmers, food processors, retailers and restaurants. A lesser known counterpart is certification for organic textiles (or organic clothing) that includes certification of textile products made from organically grown fibres. Requirements vary from country to country (List of countries with organic agriculture regulation), and generally involve a set of production standards for growing, storage, processing, packaging and shipping that include: avoidance of synthetic chemical inputs (e.g.”

   “Organic food, also known as ecological or biological food, refers to foods and beverages produced using methods that comply with the standards of organic farming. Standards vary worldwide, but organic farming features practices that cycle resources, promote ecological balance, and conserve biodiversity. Organizations regulating organic products may restrict the use of certain pesticides and fertilizers in the farming methods used to produce such products. Organic foods are typically not processed using irradiation, industrial solvents, or synthetic food additives. In the 21st century, the European Union, the United States, Canada, Mexico, Japan, and many other countries require producers to obtain special certification to market their food as organic. Although the produce of kitchen gardens may actually be organic, selling food with an organic label is regulated by governmental food safety authorities, such as the National Organic Program of the US Department of Agriculture (USDA) or the European Commission (EC).”

   Does sustainability marketing make people think food is healthier? A systematic review of health halo effects.

   “Of these, 25 studies met our inclusion criteria and were included in the review. We conducted a narrative synthesis of the evidence, analysing patterns across study designs, types of sustainability-related cues, and health-related outcomes.ResultsAcross the included studies, sustainability labels and claims frequently increased perceived product healthiness. These effects varied by the type of health-related outcome considered and were more consistently observed in general health perceptions (i.e., food healthiness) than in evaluations of specific nutritional attributes (i.e., calorie content). They also tended to be stronger when these signals were presented in isolation rather than alongside additional product cues.ConclusionThis review extends the literature on health halo effects to sustainability-related food information and suggests that sustainability labels and claims may influence consumer judgments beyond their intended environmental or ethical purpose. These findings highlight the importance of considering potential spillover effects when designing and regulating sustainability-related information in food environments.”

   Pesticide Residues, Gut Microbiota, and Gastrointestinal Outcomes: A Scoping Review of Human Evidence.

   Comprehensive reviews in food science and food safety (Ye et al.)Published Sep 1, 2026Checked Oct 4, 2026

   “Risk of bias (RoB) was appraised with ROBINS-E and Cochrane RoB 2.0, and evidence was synthesized in a 60-cell pesticide-class × outcome gap matrix. Twenty-eight papers were retained; 20 full-text-extracted human studies entered the synthesis, populating 20 of 60 cells (33%). The strongest convergent within-scope signal was OC exposure × IBD, where three cohorts agreed in direction (hazard ratios 1.56-1.61; Faroese risk ratio 3.04 on 37 cases). As a microbiota-mediation exemplar for an adjacent non-GI endpoint, the MCMC Nanjing pregnancy cohort linked a pesticide environmental risk score to gestational diabetes (adjusted odds ratio 4.5; 95% CI, 1.4-13.8; internal-validation area under the curve 0.83), with a Dorea-branch microbiota mediating part of the path. Glyphosate × IBD and neonicotinoid × any GI outcome remained empty. RoB centered on Moderate (11 of 22 rated cohorts), with six elevated-bias contributors. Biomarker-anchored prospective cohorts targeting the empty cells should be the next research priority.”
