This week Dr. Sarah and Stacy answer a listener question. Listener Question: Thanks for continuing to podcast. Crazy times in the world and you and Sarah’s voice is so utterly comforting. Anyway, podcast question! Water intake. I don’t think you guys have done a, 'how much water do we need', podcast episode. A deep dive into this would be really helpful. The standard advice seems to be either one amount for men and one amount for women, or, half your body weight in oz. Which is correct? Or is there another answer? What about just drinking when thirsty? I also have wondered, how much water did our ancestors drink? I assume the water was maybe harder to come by back then so maybe they were drinking less? This is the assumption I’ve always made and has led to me drinking intuitively, which has more than likely led to me being chronically dehydrated :) I feel like with all the conflicting info, it would be great to hear the science. By the way Stacy, as a side note, after about a year I finished catching up on the podcast. I know you are sorry, I am not ;). When searching for a water-related episode, I and came upon an episode called Thirsty Brain. I was like, for sure this has to be about how water intake affects our brain. Nope. Lol. But that was a great episode about Matt’s podcast, called Thirsty Brain :) love you guys.  Thanks again for all you do!" - Jessica  You can find the full show notes with links to the products and articles discussed on this episode here.

(4:27) Their reverse osmosis system has been sitting on Stacy's counter for a month now, but there is one person in the house who is not convinced that it is a good idea. Stacy first loved this system because of the information that Dr. Sarah shared, but second loved that it is endorsed by Erin Brockovich. Dr. Sarah has had an AquaTru for over four years, and what she loves about them is how different their technology is. It’s the only counter-top reverse osmosis system — in a category all its own. It is not bottled water, not a fridge filter pitcher like Brita or Pur, and is not an under the counter or whole house system needing installation. AquaTru is the only purifier to remove the ‘forever chemicals’ known as PFOAs and at the center of the movie Dark Waters. Most reverse osmosis (RO) systems waste four gallons of water for every one gallon they produce. AquaTru uses a patented water conservation technology that is about 12x more efficient than professionally installed under-the-sink RO systems. RO is the best way to filter water.
