[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!
[A]: Positive

[Q]: I enjoy my Kavli Crispy Thins so much and so often that I now order by the case. Besides being naturally low fat and naturally nutritious, Kavli Crisp Thins are a great replacement for salty, fattening nachoes, and/ or pizza. With Crispy Thins, you can make your own nachos by layering the Crisps w/ chopped tomatoes, cheese, even ground meat ... pop 2 Crisp Thins w/ toppings in microwave, and you've got your delicious nachos, (or pizza). I have Crispy Thins w/ melted cheese every morning ... great way to start the day. No, I don't work for Kavli ! This is not an ad, but a truthful review. Also so nice and easy to be able to order Kavli ( and just about everything) via Amazon.
[A]: Positive

[Q]: I do actually get heartburn from coffee, so I was excited to try this "low acid" french roast coffee. I have noticed that it does seem less acidic, I am on my third cup with no heartburn so far... though I would not chose to drink this as my standard coffee. I normally brew dunkin donuts brand coffees at home and really enjoy their flavor. There are a few other brands that I will buy when they are available in this town, though that is rarely. I did not care for the flavor of this coffee. It was very wooden tasting and almost had an old burnt coffee flavor to it. I guess if you HAD to drink coffee and were really worried about the acid then this would work... but I'd rather stick with good tasting coffee and follow it up with a tums. I would not purchase this product on my own.
