SFA: saturated fatty acids; PUFA: polyunsaturated fatty acids; MUFA: monounsaturated fatty acids. Omega-3 Index: C20:5 n-3 + C22:6 n-3. Total n-3: C18:3 n-3 + 20:5 n-3+ 22:6. n-6: C18:2 n-6 + C18:3 n-6 + C20:2 n-6 + C20:3 n-6 + C20:4 n-6 + C22:2 n-6. Data are shown as mean (standard deviation) or median (interquartile range) depending on the distribution.
