If you read the
reviews of the list on the page, it looks like she must recommend Natures Logic very highly, as well as Acana and Bravo (this is all public info on the page, I'm not revealing anything). I always forget about Natures Logic since so few feed it here, but those who do truly love it. WoogieMan use to feed it and he absolutely loved it for his kiddos; he did a ton of research about it too.
