European paediatric advice on soy formula
Soy protein infant formulae and follow-on formulae: a commentary by the ESPGHAN Committee on Nutrition.
Overview
ESPGHAN Committee on Nutrition. J Pediatr Gastroenterol Nutr 2006 · PMID 16641572 · DOI 10.1097/01.mpg.0000189358.38427.cd
Soy formula has no advantage over cow-milk formula and should be used only for specific reasons because of possible effects of its plant oestrogens.
Does the study support the specific claim? Partly · Methodological quality: moderate

5. Actual results
- Results
Soy formulae can be used for term infants but have no nutritional advantage and contain high concentrations of phytate, aluminium and phytoestrogens 'which might have untoward effects'; indications include severe persistent lactose intolerance, galactosaemia and ethical (vegan) reasons; not for prevention of allergy; not for infants with food allergy in the first 6 months; no role in colic.
- Absolute risks
Not applicable
- Authors' conclusion
Restrict soy formula to specific indications.

9. Assessment of the statistical interpretation
Not applicable.
10. Relevance to the specific claim
Partly endorses caution about phytoestrogens in infant formula (C-LEG-10) while not stating proven harm; limited to infant formula.
