Now what about yours? Please send your saliva sample to our Into Your Hands LLC laboratory for analysis. So, no, my coffee does not make my saliva too acidic. The result? My saliva faithfully held the course, registering a delightfully neutral 7.0. After starting my day with freshly squeezed lemon juice, which, brought my saliva to a pH of 7.2 initially and 7.0 after checking again 30 minutes later, I drank a cup of coffee and re-checked. It turns out that the pH of my coffee is 6.6, the same as my waking saliva.
I drink weak coffee as a way of splitting the difference: one table spoon of organic coffee grounds per 10 to 12 oz.
Others blame the caffeine or acidity for a variety of ailments. Some tout the antioxidants in coffee and claim the drink to be a heroic component of a healthy diet. I want the answer to this research question to favor my continued consumption of coffee. Does coffee make your saliva too acidic?įirst, I should admit some bias here. ACV, by contrast, can be squeezed, bottled, shipped, purchased, opened, refrigerated, reopened and resealed and re-refrigerated day after day for weeks, and still have an alkalizing effect on your saliva. Lemon juice must be freshly squeezed-not squeezed 30 minutes ago, nor squeezed weeks ago and then bottled and shipped to the supermarket-or else it will not succeed in alkalizing one’s saliva. So, yes, ACV will alkalize saliva, at least temporarily. After 15 minutes, my saliva had returned to 7.0. Drinking ACV raised my saliva from 7.0 to 7.6, notably alkaline. What about bottled apple cider vinegar?Īpple cider vinegar (ACV), diluted in water, registered a pH of 5.8. After drinking the lemon-juice solution, the pH of my saliva dropped to 6.4. My saliva prior to this experiment was at a pH of 6.6. My batch of bottled lemon juice, diluted in water, had a pH of 5.5. Does bottled lemon juice alkalize your saliva? After drinking the 5.8 pH lemon juice, the pH of my saliva dropped to 6.8. My saliva prior to drinking the lemon juice on this day was 7.0. This time, the lemon juice began at a pH of 5.8-still acidic, but higher than the previous day’s batch (perhaps due to the uniqueness of each lemon, or the degree to which I diluted it in water?). The following day, I repeated the same experiment but with one key alteration: I let the lemon juice sit out for 30 minutes before drinking it. Does 30-minute old lemon juice alkalize your saliva? Hence, I am convinced that freshly squeezed lemon juice will make saliva more alkaline, in this case essentially neutralizing what began as slightly acidic saliva. After 15 minutes it dropped to 7.1, and after 30 minutes it dropped to 7.0, neutral. You might expect the result to be somewhere in the middle of lemon juice (5-ish, or 5-isch for those of you following this blog in Germany) and pre-lemonized saliva (6.6), but instead the test strip turned dark green, registering 7.2 on the pH scale. Then, I drank the lemon juice solution and re-checked my saliva. (I’ll guestimate it at 5.0, but my test strips are indexed from 5.5 to 8.0, so all I can say is that the strip was a brighter and lighter yellow than the 5.5 reference point.) I diluted freshly-squeezed lemon juice in water, producing a solution with a pH of less than 5.5.
