Stunting and nutrient deficiencies in children on alternative diets

Studies in children fed alternative diets showed that anthropometric parameters and the intake of energy and nutrients by macrobiotic children deviated most from current norms. Therefore weaning practice, growth and haematological status were investigated in 3 age-cohorts of macrobiotic fed infants between 4 and 18 months of age and a control group. A mixed longitudinal design was used for this study. Main findings were a growth retardation which was strongest in the second cohort (8-14 months of age) and related to a diet low in energy density, fat and protein. Haematological data revealed very low vitamin B12 concentrations with consequently low values of haematocrit and red blood cell count and higher values of mean corpuscular volume and mean corpuscular haemaglobin mass in the macrobiotic group. High folate concentrations also seemed to be a consequence of Vitamin B12 deficiency. Iron deficiency was found in 15% of the macrobiotic group vs. no infants in the control group. Nutritional recommendations acceptable within the macrobiotic philosophy are discussed.
