Water Water Everywhere, But Nothing Left to Drink
Over the past decade, specialty drinks such as enhanced teas, exotic juices, flavored waters, “superfood,” probiotic and sports drinks, have become popular alternatives to traditional carbonated soft drinks.. Unfortunately, most of these new beverages are just as acidic; and thus, just as unsuitable for refluxers as their predecessors. This is not good news. So what can a refluxer drink?
We hope that readers of Dropping Acid: The Reflux Diet Cookbook and Cure (and of this blog) already know that soft drinks (all carbonated beverages), bottled or not, are bad for reflux and most every other bottled thing is NOT okay either. It is the acid that is added to kill pathogenic bacteria and prolong shelf-life.
So, what can a refluxer drink? Our first advice is to read labels carefully and avoid the acids. If you’re going to control your reflux, you are going to have to learn to read labels and look out for ascorbic acid, acetic acid, citric acid, “vitamin C enhanced,” and “100% Vitamin C.” These are all code words for VERY ACIDIC!
How We Did the Testing (Materials & Methods): With hundreds of drink choices on the market, and seemingly more and more appearing every week, it is beyond our capacity to test the pH (acidity) of every variety and every drink brand. What we did do is test the most available drinks with an eye towards beverages refluxers might possibly be able to drink. We did not test carbonated, caffeinated, or chocolate-flavored drinks, because we already know these beverages are bad for refluxers.
Teas
More than one cup a day of caffeinated beverages, like coffee, green and black teas are not okay on The Reflux Diet. Some herbal teas, like chamomile, are terrific. Beware of other herbal teas. Though many herbal teas are good, we found that herbal teas infused with a fruit flavor are extremely acidic (as low as pH 2.8). Anything infused with orange, raspberry, lemon, or other citric flavor should be a red flag. As for the variety of bottled teas on the market, refluxer stay away. None that we tested had an acceptable pH for The Reflux Diet.
Bottled Smoothies
We are big advocates of homemade, pH-balanced smoothies, but what about those bottled smoothies that are so easy to grab in the grocery store? Well, the answer is some are acceptable and some are not. As you can guess, anything with a citric-fruit base is bad. Of the rest, vanilla flavored, high-protein drinks seem to be best.
Slim-fast Vanilla and Slim-fast Strawberry N Crème are both great (pH 6.9 and pH 6.8 respectively), as is Odwalla’s Vanilla Monster Protein Drink (pH 5.8) while Naked’s Green Machine (pH 4) and Odwalla’s Superfood Juice (pH 3.9) might seem okay but are bad.
Specialty Waters
Specialty waters, in most cases, are vitamin enhanced and not okay because the vitamin enhancement adds acid. A few exceptions exist. We have found that all tested brands of coconut water with no acids added are above pH 4.7, for instance, and unflavored Pedialyte is pH 5.4 and therefore, acceptable. With specialty waters especially, check the labels and look out for acids. Specialty waters that seem innocent (Vitamin Water, pH 3.1 – 3.6; Hint Unsweetened Essence Water, pH 3.9) can be deceptively acidic.
Probiotic Drinks
Probiotic drinks, like kombucha and kefir, are too acidic. Always steer clear. If you need probiotics, take the pills.
Bottled Juices
The rule with bottled juices is fruit juices are not okay and with vegetable juices you must be wary. A case in point is two carrot juices we tested. Odwalla Carrot Juice is all natural and pH 6.3; however, Ralph & Charlie’s Everyday Carrot Beverage was pH 3.9. Looking at the two bottles side by side, you would not notice a difference in appearance. Only when analyzing the label would you see that Ralph & Charlie’s Everyday Carrot Beverage is enhanced with acids and other preservatives and flavorings.

Is it the Slim fast “low-carb” vanilla shake you are refering to or the “French Vanilla” shake? There is no “just” vanilla shake. I really want to try this since all I drink is water and milk at this point.
Thanks!
Both the “low-carb” vanilla shake and the “French Vanilla” shake are pH 6.9.
I think this is very important….Both the slim fast vanilla and strawberries and creme rtd shakes have citric acid in them. In the book you advise to steer clear of any products with this ingredient. What gives?
Is there a way that I could test the pH of my favorite drinks at home? I live in a small town that doesn’t offer many of the items on your list. Also, I would like test the difference between a traditionally brewed cup of coffee and a “cold brewed” cup, which I’ve heard is much less acidic.
I have never tried The Reflux Diet, this whole concept is new to me even though I’ve had GERD for over 10 years now, but I don’t know if I can give up coffee.
I got an advice that natural Chinese Green Tea works for Acid Reflux ut after reading the post, I’m not quite sure if it works. Any ideas?
What a great site! As someone new to LPR and likes to have a post workout, shake, have you ever rated the rtd protien shakes (muscle milk, myoplex, etc…)? My old favorite mix has way too much ascorbic acid in it so I know that wont work so any insight you can offer would be greatly appreciated.
Thanks for the list! I drink mostly tulsi herbal tea, which is in the basil family. They have plain, herbal and fruity flavors. I guess that the fruity flavors are acidy, but do you have an idea about the herbal flavors like original, honey chamomile, licorice or jasmine? Thanks
Hi, I almost forgot-I drink a green smoothie or green juice (both homemade) every morning. I tend to use leafy greens plus cucumber, celery, green or red apple and some lemon. Could you recommend other combinations? Thank
One day into my diagnosis of LPR and making a shopping list! I read in my Dr’s handout from your book of best foods that apple juice is acceptable. My question: Is Apple Cider acceptable as well?
How about alkaline water at 9.5pH? I drink it for my heartburn and it seems to be helping with immediate relief. I would imagine the mechanism is the same as with any other non-acidic juice or food but I am wondering if Dr. Koufman has a particular view on this. Thank you.
