 You're much better off dissolving a teaspoon of baking soda in some water and drinking it rather than having alkaline water. Alkaline water will not change your pH one bit. Welcome to the Dr. Gendry podcast. Now I talk a lot about the optimal foods for human health, but there's one thing I've failed to talk to you about. And in fact, it may be the most essential thing you can put into your body. And if you don't get enough of it, you could die in just a matter of days. So what could be so important that I devote an entire episode to it? Water. That's right. On today's episode, I'm going to dive deep into a subject most of us don't even think much about, hydration. So strap in to hear my thoughts on tap versus bottled water, the benefits and dangers of water fasting, how much water you should drink every day, trendy waters and much, much more. Okay, so let's start with one of the most basic questions out there. Do I really need to drink eight glasses of water every day? Well the answer is no, you don't. And that idea that you need eight glasses of water a day is one of those wonderful myths just like the 10,000 step pedometer myth, which was actually invented by a Japanese company to sell pedometers. You don't need to walk 10,000 steps every day for perfect health. You actually need maybe 2,000 or 3,000. It's the same way with eight glasses of water. Most of us don't realize that if you're following a plant paradox compatible diet, you're hopefully going to eat large amounts of leaves as a part of your daily diet. And quite frankly, most animals get most of their water by eating the water in leaves and on leaves. In fact, gorillas eat 16 pounds of leaves every day and they're not sitting near a stream half the day drinking water. But that brings me to an important point that I'll talk about a little bit later in that plants are probably the best filtration system that's ever been designed to filter your water. So if you're eating organic vegetables, that plant is filled with filtered water. Not only filtered water, but you actually are getting what's called structured water. And I'll have more to say about structured water towards the end of the podcast, so stay tuned. So if you really want to get the genuine article in terms of structured water, get it by eating leafy greens and you're going to get a bunch of it. Now having said that, there are other forms of getting water into your system and that includes coffee and tea and no caffeine does not dehydrate you. It will not make you lose water, sorry about that, it's just not true. And believe it or not, wine is mostly water. So these other forms of hydration not taken to excess are perfectly acceptable ways of adding to the amount of H2O you're going to get in your body. Now what does dehydration do? Now I treat dehydration in the hospital. We do see people that come in profoundly dehydrated and among other things dramatically shrinks the amount of blood that you can successfully pump around your body. And most people who we see with dehydration actually present with low blood pressure for instance. One of the better ways, which is an old way of doing to take a look at your hydration status is to take the back of your hand and pinch the skin on the back of your hand, lift it up for about five seconds and then let it drop. That should disappear in a matter of seconds and mine's gone. If it doesn't disappear, the odds are that you are dehydrated and it's a pretty dog on good test. Now some of my older patients who are really quite skinny, it may take a little bit longer for that to happen but quite frankly we see dehydration much more frequently in older patients than we do in younger patients simply because many of my older patients have an interesting name called the anorexia of old age and simplistically that you don't eat or drink very much at all and it's actually a natural phenomenon. Can you ever drink too much water? The answer is absolutely and I see it perhaps more than I see actual dehydration. Most of the deaths you hear about during marathons are from over hydration and what happens is people hit these water stations and they're constantly sweating out sodium and chloride which is salt. They're then drinking water which doesn't have any salt in it and they dilute out their sodium and chloride into a lesser extent potassium in their blood and low sodium is really one of the biggest causes of cardiac arrhythmias in marathon runners and so when you hear about someone suddenly dropping dead on a marathon it's usually from over hydration. That's why there's warning to marathon participants, number one, don't drink too much water. Number two, try to hit the sports stations where they actually have electrolyte fluids for you to consume and interestingly enough the less fast runners who are out there for four or five, six hours are far more likely to suffer from this than the guys who are finishing in two hours. Of course I'm up there with those guys finishing in two hours so I've never had a problem. Just joking, so now let's get a little controversial, tap versus bottled water. Bottle water, are there any dangers? Is it really cleaner than tap or simple filtered water? Well so bottled water span the gamut of how these are produced and as many of you know many of the large corporations, many of the large beverage corporations have bought up bottled water companies. For instance Nestle for an example probably owns more bottled water brands than anyone in the world and Coke and Pepsi and other bottlers have simply joined in the fray. A lot of these systems use normal tap water that has undergone some form of filtration and each company uses a different form of filtration. The other I think the important thing about bottled water is we're mostly through with the BPA scare, the plastics that most bottled waters were contained in. It's still possible to get a BPA bottle, most of them have been replaced with BPS bottles but now the evidence is that BPS acts exactly like BPA. So my opinion is try not to drink a bottled water that comes in a plastic container. Now luckily there are a number of bottled waters that come in glass and I personally drink and I said this before San Pellegrino which is a sparkling water and we'll get into sparkling water towards the end. There still water it's called PANNA in a glass bottle. There are certainly other excellent forms of glass bottle natural mineral spring water that you should look for but try to avoid a bottled water in a plastic container. Tap water is it really safe to drink? Well a lot of times it depends on where you live and the filtration system that's used in your municipality and quite frankly the amount of fluoride and the amount of chloride that's being put into your water. Also the hardness of the water can have a huge effect and fun fact the amount of lithium in your local water may have a positive benefit on your brain health through the years. People who live in hard water areas interestingly enough have better heart health than people who live in soft water areas and if you use a soft water system in your house please please please make sure it's a potassium chloride soft water system not a sodium chloride soft water system. Potassium chloride softeners may actually have some health benefits but absolutely not the traditional sodium chloride soft water system. So the answer is check with your local municipality. The other worrisome thing about tap water is most of the filtration systems used in municipalities do not get rid of antibiotics in water and I can guarantee you that they are in almost all of our commercial water systems. So personally my wife and I drink bottled water at home from glass but both of our homes in Santa Barbara and Palm Springs have a reverse osmosis whole house water system as well. There are very reasonable price ones available there are really ridiculously priced ones available. The other option is get yourself a disposable pitcher many are on the market many are actually very reasonable to use but check with your local municipality before you say well I've got great tap water. Also we're going to talk about alkaline water but the alkalinity of your water varies greatly by municipalities so some will have actually very high pH's. Desert hot springs which is the community next to Palm Springs is always voted as the best water in the United States that's because their water comes from an underground aquifer that drips off a 10,000 foot mountain and it's filtered water and always wins the best taste award and highest quality water in the annual water competition. I've talked about water fasting on this podcast before but I keep getting questions about it so let me set the record straight. Water fasting has been around since recorded history and certainly it's been around since pre-recorded history. Quite frankly we often did not have food but thank goodness we had water. We can go without food for months and months and months there's been human experiments and human beings who have gone over six months without eating but you can only go without water for approximately seven days that's how important water is. Now water fasting because of its long historical significance and because fasting is associated with all the great religions people assume that water fasting is natural and it's safe and whereas if this was a hundred years ago and I'm doing this podcast probably from a soap box in the town square water fasting would be very different than it is now and that's because in our modern environment we take heavy metals and organo pesticides and other toxins which are now ubiquitous in our environment and in our food and we store them in our fat cells and believe it or not when they're stored in our fat cells they don't have a huge effect on us that's why as I use the example a giant tuna or a giant swordfish which is full of energy and full of life may have toxic amounts of mercury in their flesh in their fat but it's not affecting them so you eat that mercury and you store that mercury in your fat so when we do a water fast we virtually immediately start using up our fat for energy because we're not eating the problem is as we use that fat the heavy metals the pesticides all the other toxins are released into our bloodstream now our liver is appointed to detoxify these compounds and we have phase one and we have phase two detoxification enzymes that do a pretty reasonable job but the liver actually has no ability to detoxify heavy metals so it says I'm going to spit these heavy metals out into bile and the bile will be squirted into the intestines and I'm rid of it and everything's fine unfortunately we reabsorb those heavy metals from our intestines so that many of us doing a detox are actually increasing the level of toxins in our bloodstream because they come out into our bloodstream and we immediately recycle them back into our bloodstream and so many people including Dr. Joseph Mercola who was a big fan of water detox have really stepped back and said wait a minute that's probably not what we should be doing in the modern age and as many of you know I developed product that I use on myself to deal with this issue and I've written about if you want to detox heavy metals properly here's the steps to do is there a safe way to water fast yes and just in the longevity paradox I show you how to do this you need to complex heavy metals and the best way to do that is the use of chlorella and the use of activated charcoal I also think you need to rev up your liver enzymes melt thistle is a great way a compound called D limonene is a great way dandelion greens are a great way and this is all in the longevity paradox so please don't just say I think I'm going to do a seven-day water fast Peter Atia is backed off on his seven-day water fast and is now this year only going to do three-day water fast which I think is a much more reasonable approach okay time for a lightning round of quick questions and answers let's go is alkaline water healthy so we've had one of the world's experts on alkaline water on my podcast and I do suggest you listen to it here's the hilarious thing about alkaline water everyone thinks that we need to have an alkaline environment to be healthy in fact where capillaries deliver blood and nutrients to the cells it's actually a slightly acid environment and that's how things actually happen alkaline water has actually less ability to alkaline you than for instance baking soda baking soda so if you really want to have a benefit of an alkaline environment you're much better off dissolving a teaspoon of baking soda in some water and drinking it rather than having alkaline water alkaline water will not change your pH one bit there aren't enough ions dissolved to change your pH and as you know my colleagues at the medical college of Georgia where I went to medical school recently published a paper that having a teaspoon of baking soda a couple times a day improves athletic performance it's actually an old hack of professional athletes and actually may protect kidneys from inflammation so no alkaline water if you want to have an alkaline water machine knock your socks off a lot of the reverse osmosis machines will give you alkaline water I have one but don't be confused by what benefit you're going to get from that alkaline water it's actually the reverse osmosis that's probably doing the trick is there anything wrong with ice water well first of all it depends on where the ice is being made number two ice water is incredibly good for you think about this you have to cool the ice water down to normal temperature and in doing so you use heat from your body and that heat requires energy so interestingly enough the more ice water you drink the more energy you use up to cool off or heat up that ice water so you actually can have a benefit by drinking ice water rather than warm water how healthy is hydrogen infused water well we've had a podcast about this and I can tell you I think that the discovery of the benefits of molecular hydrogen is going to be one of those ground-shaking changes in how we understand how hydrogen works in our body for health just a little teaser from my next book the energy paradox which will be out in the fall of this year people with Parkinson's disease have been discovered that their gut microbiome does not make hydrogen out of the food they eat whereas normal people's gut microbiome makes hydrogen gas out of the food they eat and I'll leave that teaser because there's more on hydrogen to come so I think hydrogen water and I drink it daily is really one of the game changers if you're interested in brain health and if you're interested in longevity should I drink water with a meal why and why not so you need gastric acid to digest protein we use acid for one purpose and one purpose only in terms of the food we eat and that is to digest protein if you dilute the gastric acid with water you'll actually slow the protein digestion now that may be believe it or not a good thing if it slows gastric emptying but here's a crazy fact there's a little valve at the end of your stomach called the pyloric valve the pylorus that senses when gastric acid goes away and that means that your protein has been digested and it's ready to empty the protein or the stomach contents into the small intestine for further digestion and absorption if you dilute out the acid with too much water you inadvertently open the gates too soon and your stomach contents empty into the small intestine too soon this can do two things number one it can actually spike your blood sugar inadvertently and it can lead to protein that's not fully digested and that protein will actually undergo fermentation and you may actually get the gas and bloating that you associate with irritable bowel syndrome but it may be because you had too much water with your meal and you started the process that way can I drink sparkling water as a replacement yes here's the proviso most sparkling waters merely bubble up carbon dioxide into the water and that actually makes for an extremely low pH in those waters they also can increase the phosphorus content so Italian law requires that all Italian sparkling waters which quite frankly are in glass have to be pH balance that has to be neutralized sand Pellegrino by the way has the most neutral pH of any of the sparkling waters on the other hand if you guys are sitting around drinking lacroix or something like that as a wonderful sparkling water you may be getting a pretty impressive acid load if you're having several of these a day so and please make sure your can is BPA free make sure you found a can that doesn't have a liner that has BPA in it glass has no BPA are there any people shoot who should avoid sparkling water yeah if you can't burp it's probably a good idea to avoid sparkling water because that gas has got to go someplace and if it doesn't come out the top end I guarantee it'll come out the back end are the chemicals in water we should worry about you betcha there are aurora really kind of talked about this I'm very suspicious as are many others particularly Dr. McCullough about the fluoride content in water most of the good quality water filters that you can purchase will get fluoride and chlorine out of your water as well as some of the other chemicals in addition to getting the antibiotics out of your water that's one of my big fears I don't have any data to share with you yet I'm trying to find it on whether these filters filter out glyphosate the ingredient in Roundup which quite frankly is in most of the things we eat and probably in our groundwater as well what do you about think about testing your water what pH should it be at well again that's going to vary from municipal municipality to municipality it's not a big deal to check the pH of your water but for fun check the pH of your sparkling water and you'll probably be pretty shocked about what you're drinking what structured water is it better so structured water is basically six water molecules that are arranged in a hexagonal shape what's interesting is in the human body most evidence is that we change the water we drink into structured water we know that structured water is what is in plants as I mentioned before so should we drink such structured water to get structured water in us well it's not going to hurt you but I'd much rather eat plants to get structured water and quite frankly as you're going to learn in the energy paradox the reason you have structured water in you already is because of the way you actually absorb water from your intestines and there's another teaser for you raw water trend is it dangerous to drink untreated raw water it depends on where it comes from if you're on a camping trip to Thailand and you're going to drink water out of a creek I would highly not recommend it in fact when I do mission work in Africa and India I always bring water treatment tablets and filtration systems with me because the idea that that raw water is good for me is not a good idea it's loaded with parasites some of which can infect you for the rest of your life on the other hand long ago I invested in a company in Utah that brought water up from a glacier from 10,000 feet below a mountain that they had tapped into that glacier formed millions of years ago it's sterile it has no organisms in it and is it great stuff yeah unfortunately went out of business that's too bad so it depends but the idea that water should be raw most spring water is by definition a raw water but you got to be careful a stream is not necessarily raw water that you want to drink so that's it for the Dr. Gundry podcast I hope you've learned a few of my opinions on water I know I'm going to get a lot of feedback on this one but I'm Dr. Gundry and I'm always looking out for you I hope you enjoyed this episode of the Dr. Gundry podcast make sure to check out the next one here I'm talking about hydrogen yeah the most abundant element in the universe the same thing that's in the air you breathe and the water you drink and there's a really easy way to supercharge this molecule to reduce inflammation boost recovery support a healthy heart and improve the appearance of your skin
