In Table 2 is observed the mean amount of consumption for different macronutrients and micronutrients in regard of hemoglobin status without the use of the Hb correction factor for definition of anemia (Hb < 11 g/dl) (n = 16), normal Hb values (Hb = 11-14.5 g/dl) (n = 238) and erythrocytosis (Hb > 14.5 g/dl) (n = 84). The gene discussed is GSTM1; the disease is anemia.
