Example Input: I really like this granola - their hemp granola is my favorite. REALLY good stuff. However - it's just too sweet for my taste. Most granola is dreadfully sugar-laden, and other than the healthy ingredients, I feel like I'm chomping on some commercial-grade grocery store sugar cereal... -___-  That said, the texture is very satisfying and it is tasty. Just a bit sweet. You've been warned.. ;)
Example Output: 3

Example Input: I have been looking for alternatives to made-in-China jerky. Because of - I presume - the amount of meat required to make real jerky, this has been a difficult endeavor. Even product lines like Milo's Kitchen source jerky from China while making the rest of their products - the ones they can process with fillers - in the US. True Chews markets US-made jerky treats but the meat is processed with other ingredients into a jerky-shaped chew that doesn't much resemble actual jerky.  Likewise, when I received these treats they were not what I expected. "Jerky," to my mind, means plain, dried meat. I thought the other mentioned ingredients would be added as a coating for flavor, but I expected a largely unprocessed product. In fact it is a cubed, compressed product containing significant amounts of grains and other ingredients as filler. My dog liked them but for the price there are other treats he likes better.  Maybe my expectations of a treat labeled "jerky" are out of line, but I know a lot of people besides me are looking for a US-made jerky treat, and in my opinion this isn't it. On to Blue Buffalo Wilderness jerky. It is several times more expensive but so far the only "real" US-made jerky I have found.

Example Input: This soup is very good tasting if you like seafood, like I do. I am finally finishing my case of cans, because it is good food. However, I do not plan on getting any more of this particular product because every can has a little something extra: bits and pieces of chitinous shell, mostly from the shrimp but also a few hard pieces now and then from the lobster. They are small pieces, which means taking small spoonfuls and not biting down hard on anything, and don't eat the last spoonful. I find six to eight pieces of this debris in each can. Like I said before, I am finishing the case, because it is food and pretty good at that. But I just don't appreciate having to be that careful with my soup.
