Example Input: Coconut Water with a splash of Pineapple  This is refreshing!  It's sweet, but not too sweet.  The coconut flavor isn't pronounced, and the pineapple isn't so overpowering that it tastes like syrup.  It's clean tasting.  According to the packaging, "it has five essential electrolytes, more potassium than a banana, no fat, no cholesterol, and no preservatives."  There's a smidge of fiber, 0.8 g of protein and 16 g of sugars.  I suspect most of the sugar comes from the pineapple, but "cane juice" is one of the ingredients, too. The 8.5 fl oz carton comes to 75 calories.  If you sign up for subscribe & save, it's less than $1 per carton.  Actually, the carton is the only thing I don't like about this drink.  It's sort of hard to drink directly from because there isn't any air getting let in when you drink, which makes a vacuum.  This was solved by pouring it into a glass.  *whew*  This was good.  I will definitely get more, and I highly recommend this to people who like pineapple juice.

Example Input: I'm presently on a diet and I was at my Fresh and Easy Neighborhood Grocery looking over possible diet foods. I wanted things that were tasty, non-fat and low in calories. I came home with about a dozen items. That's how I discovered the Tillen Farms Pickled Crispy Asparagus. Well, I've always liked asparagus anyway and I've enjoyed several brands of pickled asparagus. This Tillen Farms brand is really, really good! It's the best I can recall. There's an excellent flavor and a big clove of garlic down in  the bottom of the jar which I'm looking forward to eating. I can't believe how good this asparagus tastes and right on the front it says "only 60 calories per jar!" Now this is my idea of a good diet food!  Gary Peterson

Example Input: My 35-lb dog could not break these treats by chewing on them. She gave up after only a minute or so and decided to look elsewhere for a treat.  I was unable to break the treats in two even though they are scored across the middle.  My toy breed dog thought it was fun to play with, but he couldn't get much headway trying to chew it either, and never ate it.  They need come out with something soft!
