Eating foods that don't cause much inflammation might help your red blood cells live longer by reducing damage from oxidative stress.

Low-inflammation diets reduce oxidative stress, which leads to an increase in the lifespan of red blood cells.
Unverified — no studies directly back this
We haven't found enough studies to verify this claim yet.
Eating a diet with lots of fruits, vegetables, and healthy fats is low in inflammation. This diet contains special substances that help the body fight damage to cells. These substances turn on a protective system in cells that makes more damage-fighting enzymes. They also calm down the immune system, which normally causes swelling and damage. Together, these effects reduce the harmful molecules in the body. Since red blood cells are easily harmed by these molecules, protecting them means they live longer.

Eating foods that don't cause much inflammation might help your red blood cells live longer by reducing damage from oxidative stress.
Mechanism
1 studyEating a diet that is anti-inflammatory provides the body with special molecules that boost its natural defenses against damage and calm down the immune system. This reduces the harmful effects of oxidative stress, which helps red blood cells stay healthy and live longer.

Together, these effects reduce the harmful molecules in the body. Since red blood cells are easily harmed by these molecules, protecting them means they live longer.
The body takes in antioxidants from foods like fruits and vegetables.
These antioxidants activate a protective protein called Nrf2 and block an inflammatory protein called NF-κB in cells.
Nrf2 increases the production of antioxidant enzymes like superoxide dismutase and catalase.
Blocking NF-κB reduces the release of inflammatory chemicals that cause harm.
The increased antioxidant enzymes and reduced inflammation lower the amount of damaging oxidative stress in the body.
Lower oxidative stress means less damage to the membranes and proteins of red blood cells.
Healthy red blood cells stay functional and avoid being removed prematurely, so they live longer.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Low-Inflammation Diets and Red Blood Cell Lifespan in Humans Measuring Oxidative Stress Biomarkers
A systematic review and meta-analysis of randomized controlled trials in adult humans comparing low-inflammation diets to control diets, measuring oxidative stress markers (e.g., malondialdehyde, glutathione levels) and red blood cell lifespan (e.g., via biotin labeling or chromium-51 tagging), with at least 4-week intervention duration.
Double-Blind Randomized Trial of Anti-Inflammatory Diet vs. Standard Diet on Red Blood Cell Survival and Oxidative Stress in Healthy Adults
A 12-week double-blind RCT in healthy human adults assigned to either a low-inflammation diet (e.g., Mediterranean-style) or an isocaloric control diet, with baseline and endpoint measurements of oxidative stress (e.g., F2-isoprostanes) and red blood cell lifespan using biotin labeling.
Prospective Cohort Study on Long-Term Adherence to Low-Inflammation Diets and Red Blood Cell Longevity in Adults
A 2-year prospective cohort study tracking adults with varying dietary patterns, measuring inflammatory markers (e.g., CRP), oxidative stress, and red blood cell lifespan at intervals using validated biomarkers and dietary adherence scores.
Case-Control Study Comparing Dietary Inflammatory Index Scores in Individuals with Normal vs. Extended Red Blood Cell Lifespan
A case-control study comparing dietary histories (using Dietary Inflammatory Index) of individuals with documented extended red blood cell lifespan (cases) to matched controls with average lifespan, adjusting for age, sex, and health status.
Cross-Sectional Analysis of Inflammatory Diet Scores, Oxidative Stress, and Red Blood Cell Lifespan Markers in a General Adult Population
A cross-sectional study of 1,000 adults assessing dietary patterns (e.g., DII), plasma oxidative stress markers, and indirect indicators of red blood cell lifespan (e.g., reticulocyte count, hemoglobin turnover), with statistical adjustment for confounders.
