Input: Consider Input: I have tried various brands of stevia, but I always come back to NuNaturals. I buy the 12 ounce container because I use it to sweeten everything. If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you. I drink a lot of tea, and this is my sweetener. A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem. Highly recommended.

Output: Positive

Input: Consider Input: I am training for a half marathon. At the start of my training I wasn't taking cherry juice. As I increased my long runs each week my knees and hips were so sore. I started to take this cherry concentrate and ever since then I have felt pretty good. I take the juice every morning with my breakfast. It has a very strong flavor but mixes well with apple or orange juice. The half marathon I'm running in is this weekend and I feel ready for it thanks in part to the cherry juice helping reduce the pain. This stuff works for me.

Output: Positive

Input: Consider Input: I have a 11 yr old Pomimo (1/2 Pomeranian, 1/2 American Eskimo) who seems to only like human food. Although I'd love to give him human food all the time, I know it's not good for his digestive system, and it doesn't have the proper nutrients required for a dog, especially at his current age. Upon trying various brands including Blue and Call of the Wild, I couldn't justify the price in comparison to how little my dog liked the taste. After reading some positive reviews here on Amazon for Newman's, I decided to give it a go. Surprisingly, my dog started eating the food immediately after I poured some into his dish. He never does that with other dry dog food, and usually waits to eat after I've given him a nibble of everything that I eat during the day. What makes it even better is the reasonable price for the quality. Yes, I understand that organic and quality US-made food are naturally more expensive, however some of the brands charge double of Newman's and provide only half the taste. As humans, we're usually sold by the nutritious & wholesome advertisements when buying dog food, however I think its pretty important for my dog to actually like the taste of the food also. Newman's seems to be the ticket for both nutrition and taste. Will be buying Newman's as a regular!
