Acidic & Alkaline Foods

Below are some tests that I conducted on myself to see if particular foods were acidic or alkaline. I had to do this because if you look around the web you will find a lot of conflicting information on which foods are acidic and which are alkaline. There doesn’t seem to be any definitive research on this topic.

For example, one source claimed that dried apricots were very alkaline. But when I tested this on myself, my pH dropped from 6.2 before I ate the apricots to 5.6 afterward. And that’s exactly the same result I got when testing Coca Cola, which can burn through metal!

My testing is obviously not scientifically conclusive. Human biochemistry is rather complex, and testing on only one subject cannot lead to any firm conclusions. Nevertheless, if this exercise leads me to a more pH-balanced state, then I will consider it a success.

pHydrionI did all of these tests on an empty stomach. After eating the test-food, I didn’t eat or drink anything at all until after the next pH reading. I didn’t so much as chew a piece of gum, or take a sip of water. For foods that required water to cook, such as oatmeal, I used Zephyrhills spring water, which is pretty much neutral. I also drank a minimum amount of the spring water as I was eating some of the foods such as peanut butter. I tested the pH of my urine with pHydrion test strips. A normal human urine pH level is 6.5 to 8.0. If you drop below 6.0, then your body will burn up lots of electrolytes to right the balance, and that deficiency will cause your nervous system to malfunction. If your diet is too alkaline, you will know very quickly because you will experience heart burn.

Here is a summary of my findings. See below for the specifics on each food.

  1. Dried unsulfured apricots are the real deal. I have gout that reacts in one specific knee. When I had extreme flare-ups several years ago, I changed my diet, dropping coffee and alcohol. The knee pain got better but persisted for weeks until I tried eating a serving (about 6) of dried unsulfured apricots a day. Within a few days, my gout was virtually gone. I can now drink a glass of wine about every other day, as long as I eat dried apricots before and immediately after. Although I eat a lot of fruit, my gout comes back if I forget to eat apricots for a week or two. It’s the only thing that truly keeps the gout at bay, although figs would probably work. I tried apricots because I saw a numerical chart online with the most thorough alkalizing potential of hundreds of foods, and apricots were twice as high as the next nearest, as I recall. I’ve lost the link. But I just found this chart today: http://www.rawfoodexplained.com/acid-and-alkaline-substances/alkalinity-and-acidity-of-foods-in-metabolic-reaction.html

  2. Hello, very interesting experiment and kudos on the level of documentation for us to read. Now I am not a chemist,biologist, doctor, or nutritionist, and I did note you stated that your results were not conclusive based on the method used to obtain the results. I also noticed when you conducted these tests so my input may be moot, but there is one variable you didn’t address in your dissertation, and that is relativity. In some cases your pH was rather lower (5.8) or higher (8.0) than average and then noticed a very slight pH rise or fall and then concluded the difference to be the indicator for the pH level of the effect. The issue I take with this is if your pH was 5.8 and you tested 6.0 after eating something, why would you conclude that food to be alkaline? What if your pH prior to ingesting the food was 7.8, or 8.0 and then 7.0 after costuming the same food? Would you have concluded the very same food to be acidic at that point? My point is when your experiment isn’t controlled (as evidenced by various levels of urine pH prior to ingestion) you somehow have to account for relativity. Aside from that, I really enjoyed your work!

  3. I have just tested my Granny Smith apple from Asda with a bit of ph yellow paper and put this directly onto the apple, it came out red as acidic, my saliva came out alkaline. I thought I was doing a good thing eating apples but maybe not! Slightly disappointed :/
