McCann's Instant Oatmeal is great if you must have your oatmeal but can only scrape together two or three minutes to prepare it. There is no escaping the fact, however, that even the best instant oatmeal is nowhere near as good as even a store brand of oatmeal requiring stovetop preparation.  Still, the McCann's is as good as it gets for instant oatmeal. It's even better than the organic, all-natural brands I have tried.  All the varieties in the McCann's variety pack taste good.  It can be prepared in the microwave or by adding boiling water so it is convenient in the extreme when time is an issue.  McCann's use of actual cane sugar instead of high fructose corn syrup helped me decide to buy this product.  Real sugar tastes better and is not as harmful as the other stuff. One thing I do not like, though, is McCann's use of thickeners.  Oats plus water plus heat should make a creamy, tasty oatmeal without the need for guar gum. But this is a convenience product.  Maybe the guar gum is why, after sitting in the bowl a while, the instant McCann's becomes too thick and gluey.

Ex Output:
Positive

Please think twice about purchasing this product, especially if you have a small-breed dog. I was lured by the cute, gimmicky labeling and sold by the ingredient list, but I twice fed Merrick canned food to both of my dogs, and BOTH times, BOTH dogs were diagnosed with pancreatitis -- an illness which is dangerous,  extremely painful to the animal, and which requires hospitalization. I'm not sure if the fat content in those particular cans was high, or if Merrick uses an ingredient/additive that somehow sickened both of my (unrelated) dogs, but this food made them very ill. After their second hospitalization for pancreatitis, I spoke with other folks who had stopped feeding Merrick to their small-breed dogs for the same reason -- the food caused vomiting, diarrhea, and lethargy in their pets.

Ex Output:
Negative

these are not DOP they're just "certified" which means nothing significant. they should go a step further with a little more nonsense and write "department certified". real dop tomatoes are much better.
