Data are means ± SDs, based on the data of 44 subjects for all parameters except for zinc (n = 37), selenium (n = 42), and albumin (n = 39).

aReference range for albumin [g/L]: 35 – 53 (≤ 60 y), 34 – 48 (> 60 y), 33 – 47 (> 70 y), 31 – 45 (> 80 y). α-Toc/chol ratio: α-Tocopherol-to-cholesterol ratio.
