The Claim

Higher dietary intake of Omega-3 fatty acids is associated with slower phenotypic age acceleration in U.S. adults, with each additional gram per day linked to a 0.071-unit reduction in PhenoAgeAccel after adjusting for age, sex, race, income, education, BMI, smoking, alcohol, physical activity, diet quality, and chronic diseases.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

People who eat more Omega-3 fatty acids, like those found in fish, tend to age more slowly according to a biological age measure. For every extra gram of Omega-3 they eat daily, their biological age looks about 0.07 years younger than expected.

See the scientific wording

Higher dietary intake of Omega-3 fatty acids is associated with slower phenotypic age acceleration in U.S. adults, with each additional gram per day linked to a 0.071-unit reduction in PhenoAgeAccel after adjusting for age, sex, race, income, education, BMI, smoking, alcohol, physical activity, diet quality, and chronic diseases, suggesting a potential role for Omega-3 in modulating biological aging.

What the research says

1 study
  1. Study: Dose–response relationship of dietary Omega-3 fatty acids on slowing phenotypic age acceleration: a cross-sectional study

    People who eat more Omega-3s, like fish and flaxseeds, tend to have bodies that age more slowly based on blood tests — even after accounting for other healthy habits. Each extra gram of Omega-3 per day was linked to a small but real slowdown in biological aging.
