Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.

and THAT is  the problem. I order these by the case of 12 - and when they are good, which is over half the time they are the BEST kettle chip, THE BEST! and then I get a case of the worse - the potatos are mealy and old so I just throw them out and order again, expensive BUT when they are made with good fresh potatos they are the best - the last case is what prompted me to write this - the potatos were weird - like they were almost sour as in going bad - and I even wrote the company that makes them - SO if you want the BEST kettle chip there is try these and if the ones you get are NOT the best try again! I, myself am done ordering because it is creeping me out that they are using soured potatos and either not noticing or not caring.

My husband works outside all day long. Due to the recent heatwave, his body is depleted of fluids due to sweat. My husband uses the energy shot along with ZipFizz. The ZipFizz provides the necessary potassium to keep the body going. I personally do not recommend too many energy shot drinks during the day, but they do prove beneficial to help you keep going.
