Why Omega-3s May Help Aging Kidneys: It Comes Down to One Receptor
Based on: Tubular Omega-3 Fatty Acid Receptor FFAR4 Deficiency Aggravated Renal Aging and Chronic Kidney Disease.
Scientists found that omega-3 fatty acids slowed kidney aging and fibrosis in mice, but only when a specific receptor called FFAR4 was working. This receptor is less active in older people and in those with chronic kidney disease. When researchers removed FFAR4 in mice, kidney aging got worse, which may explain why omega-3 trials sometimes give mixed results.
Key Insight
This study suggests omega-3 fatty acids may protect kidneys, though benefits likely depend on receptor activity that declines with age.

Weak Grip Strength Linked to Higher Risk of Pneumonia and Sepsis
In over 400,000 UK adults, weaker handgrip strength was tied to higher rates of pneumonia, UTIs, skin infections, and sepsis. Each 5-kg drop in grip raised infection risk by about 5-10%. The link was strongest in underweight people, and inflammation-related proteins like GDF15 partly explained it.
Fitness Apps and Wearables May Boost Steps in Older Adults
Looking at 26 trials with over 4,000 older adults, digital tools like wearables and apps helped people walk about 800 more steps per day and get 46 more minutes of moderate exercise per week. But they didn't significantly cut sitting time or boost light activity. Standalone wearables and tools paired with human coaching worked best.
Most Older and Darker-Skinned Adults in Northern Britain Are Low on Vitamin D, Even in Summer
Researchers screened older adults and people with darker skin tones in northern Britain for vitamin D levels across the year. More than half of older adults and over 70% of ethnic minority adults had insufficient or deficient vitamin D. Summer sunshine did not fix the problem. Sun exposure alone seems to fall short for these groups at higher latitudes.
