Women who followed healthy diets over decades showed a stronger link to healthy aging than men who followed the same diets, indicating that diet may affect aging differently by sex.

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.
Whether the protective effect of healthy dietary patterns on healthy aging is consistently stronger in women than in men across diverse global populations.
A systematic review and meta-analysis of at least 15 prospective cohort studies from diverse populations, all reporting sex-stratified associations between dietary patterns and healthy aging, with standardized definitions and adjustment for identical covariates.
Whether instructing women and men to adopt the same healthy diet leads to different rates of healthy aging outcomes over time.
A double-blind, parallel-group RCT enrolling 1,000 women and 1,000 men aged 45–55, randomized to either a standardized AHEI diet or control diet, with primary outcome: incidence of healthy aging by age 70, stratified by sex and assessed over 20 years.
Whether the strength of association between dietary patterns and healthy aging differs by sex in populations outside health professionals.
A prospective cohort study following 50,000 women and 50,000 men aged 40–60 from diverse socioeconomic and racial backgrounds across the U.S. for 30 years, with dietary intake assessed every 4 years via validated FFQs, and healthy aging defined identically to this study, with sex-stratified analyses.
Whether women who achieved healthy aging had higher dietary adherence than men who achieved healthy aging, compared to their respective unhealthy aging controls.
A case-control study comparing 1,000 women and 1,000 men who achieved healthy aging by age 70 to 1,000 age-matched women and 1,000 men who developed chronic disease or cognitive impairment, using validated dietary recall data from 20–30 years prior to assess dietary pattern adherence, with sex-stratified comparisons.
Whether current dietary adherence correlates differently with current healthy aging markers in older women versus older men.
A cross-sectional survey of 10,000 older adults (5,000 women, 5,000 men aged 70+) measuring current dietary adherence via FFQ and assessing cognitive, physical, and mental health, with sex-stratified analyses.
