Steer clear of soy protein for your dogs & cats

Soybeans and soybean-related products can be found in an increasing number of commercially available pet food formulas, dry, semi-moist and wet, including many beautifully advertised, big selling brands, as well as veterinary formulas and prescription diets. Soy is a plant protein used by pet food companies to boost protein content and add bulk. Because plant proteins are less expensive than meat proteins, pet food manufacturers use them to increase profit margins.

The ingredient label might not even say soy, as it is commonly listed as vegetable broth, textured vegetable protein or TVP, and perhaps other aliases. The majority of experts on pet nutrition agree soy isn't good nutrition for cats or dogs. It is considered a low-quality, incomplete protein well known to create food allergies in pets.

Interesting. Do you have thoughts on "soy based lecithin"? I just found out that Ziwi Peak has this in it, which is what Brooky eats, and wondering if that is the same as giving her soy in terms of causing a reaction or something if she has a soy based allergy.

Lecithin is an emulsifier, it keeps the ingredients from separating. I wouldn't be worried about that, it would only be a minor component of any food, and isn't being used as a cheap way to boost protein.
