ORIM Weekly W20 2025

EDITORIAL

Late May and summer is on the horizon. We investigate how AI-powered genomics is enabling nutrigenomics at scale, and explore the role of omega-3 fatty acids in resolving chronic inflammation through a newly discovered class of lipid mediators called specialized pro-resolving mediators.

Consumer Nutrigenomics Goes Mainstream

23andMe launched a nutrigenomics module that analyzes 78 genetic variants affecting nutrient metabolism. Users receive personalized recommendations for 40 micronutrients based on their genetic profile. Early data shows adherence to genetic recommendations improves biomarker outcomes by 25% over generic guidelines.

Underground Farming in Abandoned Mines

Growing Underground (London) expanded its hydroponic farm in repurposed WWII tunnels to 10,000 square meters. The constant 16-degree temperature eliminates heating costs, and the controlled environment produces herbs and microgreens with 40% higher essential oil content than surface-grown equivalents.

Machine Learning Predicts Mycotoxin Contamination

A new ML model from EFSA predicts aflatoxin contamination risk in grain harvests 60 days before harvest with 88% accuracy, using weather, soil, and satellite data. Early warning allows farmers to apply biological controls, preventing 20 million tonnes of contaminated grain from entering the food supply.

SPMs: How Omega-3s Actually Resolve Inflammation

Professor Charles Serhan's team at Harvard (Nature Reviews Immunology, May 2025) published the definitive review of specialized pro-resolving mediators (SPMs): resolvins, protectins, and maresins derived from EPA and DHA. These lipid molecules actively resolve inflammation rather than just suppressing it, enabling tissue repair.

SPMs explain why omega-3 supplementation takes 8-12 weeks to show full effect. The body needs time to build adequate SPM production capacity from EPA and DHA precursors.

THIS WEEK IN BRIEF

► Omega-3: An omega-3 index above 8% (measured in red blood cells) is associated with 35% lower cardiovascular mortality compared to below 4% (Am J Clin Nutr, 2025).

► Resolution: Aspirin triggers the production of aspirin-triggered resolvins from omega-3s, a mechanism that partly explains aspirin's cardioprotective effect (PNAS, 2025).

► DHA: DHA constitutes 40% of brain polyunsaturated fatty acids. Low DHA status correlates with accelerated cognitive decline (Alzheimer's & Dementia, 2025).

ORIM Tip: To build optimal SPM production, consume fatty fish (salmon, mackerel, sardines) at least 3 times per week for 8-12 weeks. This is the time needed to saturate cell membranes with EPA and DHA.
