In 60–65-year-old women, higher intake of long-chain polyunsaturated fatty acids (PUFA) is negatively correlated with skeletal muscle mass, contrary to some previous literature suggesting protective effects.
For women aged 60-65, do not assume that high PUFA intake guarantees muscle preservation. This study found a negative correlation, possibly because those with lower muscle mass increase PUFA intake to compensate. Focus on protein intake and moderate activity as primary drivers.

Concomitantly, there was a negative correlation with lipids such as long-chain polyunsaturated fatty acids (PUFA).
Why this rating
Observational data showing a negative correlation, which the authors attribute to potential reverse causality.
