Red Blood Cell Proteins Can Track Biological Aging and Predict Health a Decade Later
Researchers built a protein-based aging clock from the red blood cells of over 13,000 blood donors. People with conditions like G6PD deficiency and sickle cell trait showed accelerated molecular aging. Iron supplementation appeared to reverse some of that acceleration. The molecular age scores predicted real-world outcomes like hemolysis and donor activity over a 12-year follow-up.
Key Insight
This study suggests red blood cell proteins could serve as accessible markers of biological aging.

New Aging Clocks Reveal Blood Clotting Factors May Drive Organ Decline
Researchers built a multi-layered aging clock using clinical, physiological, and molecular data from over 2,000 Chinese adults. They found that plasma proteins can predict both your age and how well your body is holding up. The standout discovery: clotting factors pile up with age and may fuel organ-wide aging and inflammation.
Tracking Your 'Biological Age' Over Time May Predict Death Risk Better Than a Single Snapshot
In over 90,000 Dutch adults followed for nearly 14 years, people whose biological age ran ahead of their calendar age had a higher risk of dying. More importantly, among 25,000 people measured twice, those whose biological age sped up over time faced even greater risk. People stuck in a pattern of accelerated aging had a 39% higher mortality risk compared to those aging at a normal pace. The results suggest that checking biological age once might not be enough.
Eating More Fruits, Fish, Nuts, and Dairy Tied to Slower Cognitive Decline
In over 3,000 Chinese older adults tracked for about five years, those who ate more from six protective food groups (fruits, vegetables, nuts, legumes, fish, and dairy) showed slower cognitive decline. People scoring highest on this diet scale declined about 0.42 points per year slower on a cognitive test compared to those scoring lowest. The effect was modest but consistent across different ways of measuring cognition.
