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.
What the research says
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.
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.

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 studyPeople 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.
