Q: 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.

A: Positive

Q: I used to buy these as healthy snacks at my office cafeteria and consider it better than a bag of potato chips.  These taste very crunchy and tasty.  Given the kind of unethical food stories we read about China - we need to see some kind of assurance and facts on the processes that the manufacturer is following to make these.  You just cannot import food stuff and sell in the US as gourmet snack food - there needs to be data backing this.  Few example of Chinese food (yuk ...):  (1) Melamine(kind of platic) in baby food and milk (so wide spread that 80% of milk in China contained this plastic in 2008)  (2) Honey contaminated with ciprofloxacin (antibiotic) - because of which it was banned in the US  (3) Soy Sauce made from Human hair (not joking google it if you want)  (4) Spurious drugs exported to African countries.  Need some good facts and quality controls from the Manufacturers that the chinese producers are complying with some good quality controls.

Q: Why, why, why did they change the formula??  Our twins loved this.  Now just like gobble gobble, they wont take it.  Company's website with the old and new formula: [..]  Only guess is that sweet potato is much more expensive than corn (both the top ingredients).  Wrote to happybaby to tell them how disappointed we are
