Changes in the muscle mass were related the dietary n-3 fatty acids and the ratio of n-6/n-3 PUFAs.

<p>The cutoff value of adequate intake for n-3 fatty acids was 1.6 g/d for men and 1.1 g/d for women (bold dotted line). The regression coefficients with 95% confidence intervals were 1.160 (0.396 to 1.924 kg) for (A), 1.043 (0.419 to 1.667 kg) for (B), −0.161 (−0.315 to −0.007 kg) for (C), and −0.162 (−0.287 to −0.036 kg) for (D). Abbreviations: SMM, skeletal muscle mass; ASM, appendicular skeletal muscle mass; PUFA, polyunsaturated fatty acid
