Example Input: I had bought this product last year my dog loved them, but... I subscribe to a couple of Bichon Frise newsgroup and they are saying not to feed these to your dog as they come from China I threw out what I had left for the outside critters in the forest.  I called Dogswell today and they verified that even though they say U.S. on them they are still coming from China.
Example Output: 1

Example Input: This mix allowed my little one to have cupcakes at his second birthday party.  They turned out great and with some homemade vanilla icing, they were a hit with everyone!  I even used Ener G's egg replacer to replace the multiple eggs the mix calls for.  One hint, bake for almost the maximum time on the directions.  They come out golden brown and moist.
Example Output: 5

Example Input: I just tried the Orange tangerine version of The Switched carbonated drink and overall I like it.  It tastes very similar to mandarin orange Slice but it uses natural juices and no HFCS.  If you are very concerned about artificial flavors and HCFS, but still want a carbonated drink, then Switched may be a good alternative.  I read the ingrediants list and it mainly included reconstituted juces and then aboiut another line of preservatives and additives, I would assume similar to those in commercial fruit juices.  Personally, I am more concerned about overall sugar and calories in my soft drinks so this little 8 oz can has 140 calories and 34 grams of sugar.  If memory serves me that is in line with the calories of most softdrinks and more sugar then most soft drinks.  Ultimately, i think this is a good tasing product, but the touted benefits doesn't outweigh the increased price and availability conpared to regualar soda.  I guess the key is still moderation.
