Hidden Additives in Food Increase Mortality by 24%.

In 2025, KM Krost and a team studied 186,744 UK adults aged 40–75 from the UK Biobank (2006–2010). They used food surveys to track 37 ultra-processed food additives like flavor enhancers, coloring agents, and sweeteners, linking them to deaths over 11 years. They adjusted for total food intake to focus on additive effects.

Living Near Ocean Boosts Life Expectancy by a Year.

In 2025, Jianyong Wu and Yanni Cao from Ohio State University analyzed data from over 66,000 US census tracts, comparing life expectancy based on proximity to water. They looked at coastal areas (oceans/gulfs within 30 miles) vs. inland rivers/lakes, factoring in urban/rural settings, to see if "blue spaces" affect how long people live.
