Isoflavones, a type of phytoestrogen, are found in soy
protein. Most traditional standard diets have soybean meal as
a major ingredient, and therefore are a significant source of
isoflavones. Please refer to
FAQ section for more information about phytoestrogens.
In contrast, casein-based purified diets such as
AIN-76A, AIN-93G, AIN-93M, and formulas with similar
ingredients, are essentially free of isoflavones. This
type of diet is sometimes used for research that requires a
minimal isoflavone background. This type of diet can be
used as the background to which isoflavones such as genistein
(supplied by the customer) can be added.
An alternative to a purified, casein-based diet is a natural
ingredient diet from our
Global Rodent Diet line. Several diets in this line
contain minimal isoflavone/phytoestrogen levels and are
commonly used for research that requires a minimal
isoflavone/phytoestrogen background. This type of diet can
also be used as the background to which isoflavones such as
genistein (supplied by the customer) can be added.
