[Q]: I adopted my dog about 6 months ago and he had digestive problems that the vet could find no cause for. He would get diarrhea with mucous in stools regularly. His stools would vary from constipated to unformed soft stool. I decided to switch him to a better quality food and did a lot of research. Newman's Own had all the qualities I was looking for, so I switched him to it gradually - 1/2 Purina One and 1/2 Newman's Own at first and gradually more Newmans' Own in the mix until finally 100% N.O. Ever since switching about six weeks ago, he has not had constipation or loose stools. I also don't hear his tummy roiling after meals like before. And despite what a few reviewers have written, the chicken and beef used in the pet food, while not "organic", is "natural" and raised without hormones and antibiotics. According to [...] ingredients list: "Natural Chicken - Raised without growth hormones and antibiotics and fed only a 100% natural, all-vegetable diet, the chicken meat provides amino acids essential for muscles, hormones, enzymes, antibodies and structural and protective tissues." Also, the beef is free-range anad range fed w/ no hormones & antibiotics. For me the evidence is clear - this is good quality food, my dog loves it and I love that when I buy Newman's Own products, the royalties go to charity!

[Q]: This product had pretty good reviews so I thought it would be safe to buy 4 packages, so I did. Boy am I full of regret now. I'm stuck with 4 packs of these beans and I can't return any them. The moment I opened the bag, I should've known. It had a stale sour smell to them. But the optimistic side of me said, these beans look fresh and plump, maybe it won't smell like that once I scrape the seeds out. I was wrong. I made two test batches to see if it was the salt I was using to make my vanilla salt but they both have that weird sour, rancid smell. I've made vanilla salt before so I know what it's supposed to smell and taste like. Unfortunately, even after a few days, this smell isn't going away. I was really looking forward to making jars of vanilla salt to give out as cheap gifts. But now I need to go buy more vanilla beans to replace these which is going to end up costing me. I'm so disappointed. I haven't cooked with these seeds so I don't know if the taste and smell transforms with heat or with any other mixed in ingredient. I know for sure though that if you're looking to make vanilla extract, vanilla sugar or vanilla salt, I HIGHLY discourage you from buying this product.
[A]: Negative

[Q]: These chips remind me of a long obsolete brand of chips we could get in middle school. They are by far the tastiest chips I've had and it's impossible to walk past the aisle without picking up the trademark blue bag and then putting the bag clip on the bag!
