[Evaluation of a new Israel infant soy formula].

A new infant soy formula has recently been developed in Israel and is being produced (Materna Tsimchit, Trima Industries, Kibbutz Ma'aborot). We compared its efficacy with that of a well-known imported soy formula (Isomil, Ross Laboratories, USA) in a prospective, randomized, double-blind study. 45 normal infants, aged 1-6 months, were monitored for over 2 months after the soy formula was started either because of cow-milk allergy or lactose intolerance. 22 received Materna Tsimchit and 23 Isomil. The study revealed no significant differences between the products with regard to compliance, behavior, symptoms, physical examination (including growth parameters and nutritional assessment), stool characteristics and complete blood counts. We conclude, given the limitations of the present study, that the new Israeli product is as effective as the foreign product.
