A:

From what I understand, soy protein isolates aren't healthy and should be avoided.

From Wikipedia: [edit] Isolates
Soy protein isolate is a highly refined or purified form of soy protein with a minimum protein content of 90% on a moisture-free basis. It is made from defatted soy flour which has had most of the non-protein components, fats and carbohydrates removed. Because of this, it has a neutral flavor and will cause less gas due to bacterial flatulence.

Soy isolates are mainly used to improve the texture of meat products, but are also used to increase protein content, enhance flavor, and as an emulsification.

Currently, the FDA is examining health concerns related to levels of the toxin furan in soy protein isolate and other foods.[1]

Pure soy protein isolate is used mainly by the food industry. It is sometimes available in health stores or in the pharmacy section of the supermarket. It is usually found combined with other food ingredients.
