Soya-based infant formulas (SIF) containing soya flour were introduced almost 100 years ago. Modern soya formulas are used in allergy/intolerance to cows' milk-based formulas (CMF), post-infectious diarrhoea, lactose intolerance and galactosaemia, as a vegan human milk (HM) substitute, etc. The safety of SIF is still debated. In the present study, we reviewed the safety of SIF in relation to anthropometric growth, bone health (bone mineral content), immunity, cognition, and reproductive and endocrine functions.

The effect of maternal diet on serum 1,25-dihydroxyvitamin D has not been determined in human lactation. Serum 1,25-dihydroxyvitamin D, other calcitropic hormones, osteocalcin, and minerals were examined in lactating and nonlactating women consuming a vegetarian or nonvegetarian diet. The vegetarian diet was a macrobiotic diet consisting primarily of whole cereal grains and vegetables; dairy products, eggs, and meats were generally avoided.

BACKGROUND:Dietary intakes and nutrient status were compared in meat-eaters and non-meat-eaters from the National Diet and Nutrition Survey of children aged 1.5-4.5 years. METHODS:Children (n = 1351) were categorized as 'omnivores' or 'vegetarians', according to whether they consumed meat or meat products during a 4-day dietary record. Blood samples were also obtained for analysis of haematological and biochemical nutrient status. RESULTS:Three per cent of children were 'vegetarian'.
