Table 5 Mean age, iron status and plasma blood lipids of the sub-group of blood donors

From: High content of long-chain n-3 polyunsaturated fatty acids in red blood cells of Kenyan Maasai despite low dietary intake

  1. 1 For normal blood lipids according to NCEP-ATP III [15] and parameter of iron status below which iron stores are considered to be depleted (ferritin) or a marked anaemia is indicated (saturation of transferrin) according to the WHO [23]
  2. 2 Only blood donors
