DIY Food Sensitivity and Allergy Testing: Coco Pulse Test and Kinesiology

The Coca Pulse Test is a simple measurement you can do at home to know which foods strengthen you and which ones make you sick. You’ll find the steps below. I offer this method because it is scientifically sound.

However, a faster technique–and the one I personally rely on–is muscle testing or kinesiology. Many chiropractors and health care professionals use this. You’ll find numerous online supports for learning muscle testing. What’s important is to find a method that works for you.

As with any skill, there’s a learning curve. But once you have it down, muscle testing is a powerful and effective tool. I rely on it to help discern supplement usage.

How the Coco Pulse Test Works

You place one ingredient on your tongue, measure your pulse, and compare it to your resting pulse rate. If your pulse significantly increases or decreases, the food is stressing your nervous system and altering your heartbeat. It is noxious to you; spit it out.

How amazing are our body’s defense mechanisms! That within seconds a seemingly innocuous bite of bread triggers alarm bells if you are gluten-intolerant. Indeed, your body knows its personal “good” and “bad.” Our opportunity is to learn to read the cues and respond accordingly. Let us be in sync with rather than work at odds against ourselves.

In 1956, the prestigious immunologist Arthur F. Coca, MD, developed this invaluable technique. His book, The Pulse Test, is in the public domain and available as a free download. I have simplified his steps below, but first, let’s look at your other options for identifying allergenic foods.

Other Effective, Semi-effective and Ineffective Tests for Sensitivities

While an elimination diet is the gold standard for identification, it requires diligence over the long haul. Muscle testing (aka kinesiology) has value but depends upon the skill of the person doing the testing. As mentioned, I muscle test and find it fast, easy and reliable. There are multiple techniques and on-line tutorials. Find the one that works for you.

The least effective test for sensitivities is lab analyses; they are notoriously inaccurate. Many of my clients have been misguided by faulty lab analyses and were set back from realizing their health goals. That’s sad, and unnecessary. Fortunately, pulse reading is quick and some people find it easy.

Four Ways to Measure Your Pulse

  • Fitbit-type activity tracker
  • Blood pressure cuff that also read pulses
  • Oximeter that is clipped to your fingertip and displays your pulse. They cost under $20 and are the most economical option.
  • Your first two fingertips: Place them gently on your carotid artery to the outside of your windpipe or on the inside of your wrist below your thumb and count the beats.

The Coca Pulse Test

Whichever method you use to read your pulse, do so when you are relaxed and seated, but not following a meal or physical exertion. Have a stopwatch, pencil and paper at hand. Set out one or more single ingredient foods, beverages, or supplements to test. For example, to test for wheat, taste 100% wheat pasta rather than a wheat bread with multiple ingredients.

The number of pulse beats counted in one minute is your resting pulse rate (normal pulses average from 60 to 100 beats per minute). The pulse can differ from your left to right side, so read the pulse on the same side for the whole testing session.

Gently regulate your breathing. The pulse is variable, so to establish your resting pulse rate, measure it for a full 60 seconds to give it time to settle. If you are counting the beats you feel on your fingertips, then count every beat for a full 60 seconds (rather than reading it for 15 or 30 seconds and then multiplying it by, respectively, 4 or 2).

Now, moving slowly (rapid movement triggers pulse variation), place the test ingredient on your tongue and either chew it or roll it around for 30 seconds; do not swallow. Now read your pulse for another full 60 seconds. If the food stresses you, your pulse will increase. A pulse shift of four or more beats per minute indicates a sensitivity or allergy to that food. (If you have O blood type, then a shift of three or more beats per minute denotes a reaction.) The greater the pulse variation, the more toxic the food you are testing is to you.

If you react to the food, spit it out and rinse your mouth with water. If there was no reaction and/or if you wait until your pulse has returned to your resting pulse rate, you may continue to test other ingredients.

If you have a sense that there is a food that doesn’t agree with you, I invite you to try this test. Having a definitive answer is empowering.

Note: The Coca Pulse Test may not be effective if you’re taking medications that control your heart rate such as calcium channel blockers or beta-blockers.

  1. Rebecca!
    Happy retirement!

    Words alone cannot thank you enough for the information you have shared on this site. I needed the September note. And am excited to see October 2nd the site still up.

    Have you noticed how much traffic the site gets? Your efforts are so appreciated. I just found this article even tho I tried to read every article in your site before September, I didn’t see this one! Thanks for the little bit more time!

    Kindest regards, love and light,

    —Jacky—

    • thanks, Jacky, yes…not sure when it will go down but it will soon expire. As stated in this blog, I do favor the kinesiology

  2. Such a great discovery to correlate pulse rate with sensitivity or allergy. Thank you for mentioning this simple practice. How is this related (or is it?) to Chinese medical practitioners taking the ‘pulses’ to read the different organs?

    Thank you so much for all of this, Rebecca. Wishing you peace and happiness in your well-earned retirement.

    • Good question about does our pulse rate correlate with the way pulses are read in Chinese Medicine. They’re different (acupuncture actually discerns six different pulses in the same area that have other subtle qualities). Glad you’ve found this useful. I value it because it gives a scientific, quantifiable result. However, personally, I vastly prefer muscle testing.

      • Thank you! Yes, muscle testing would be much faster. I never learned how to do it successfully. My pendulum sems to work. Not as fast muscle testing. Faster than taking pulse every time, tho my little oximeter does provide some quick info, too.

        Everything you have here is extremely useful. Also have all your books except one… which i’ll soon have, too. Been a huge fan for years!!! Studied with both Jean Haner and Lillian Bridges <– got certified with her only months before she passed. So your work is beyond relevant. Thank you again!

        • thank you, Susan, for your kind comments. As I’m now retired, this web page will also retire by Oct. 1 so enjoy it while it lasts.

  3. Rebecca,

    Your instructions state beats per SECOND. It should state beats per MINUTE.

    I do use an oximeter so it shows any pulse rate changes within a few seconds.

    If it actually raised 4 beats per second as your instructions state, a food sensitive pulse rate increase within one minute could be 240 beats or more plus the beginning pulse rate.

    “Now read your pulse for another full 60 seconds. If the food stresses you, your pulse will increase. A pulse shift of four or more beats per SECOND indicates a sensitivity or allergy to that food. (If you have O blood type, then a shift of three or more beats per SECOND denotes a reaction.) The greater the pulse variation, the more toxic the food you are testing is to you.”

    Please change your instructions to MINUTE instead of SECOND.

    I received an article on this method years ago and it does not match your instructions.

  4. We have been experimenting with the pulse test using an oximeter. We leave it on the finger for about a minute and take the average reading.

  5. There seems to be a mistake regarding the significant pulse increase: isn’t it four beats per minute instead of per second?

  6. If using a Pulse Ox, since it is always measuring your pulse, which number is taken to be used as the comparison number?

    Thank you.

  7. Hi

    I have fibromyalgia and I know its partly down to food sensitivity. I have had IBS my whole life and if I do Fodmap diet very strictly it helps, though hard to do. I have tried Coca test but difficult doing it with fingers so I liked the idea of oximeter. There is someone on YouTube who has done a video and says you can do with Oximeter but someone has commented that they tried and it didn’t work. I don’t have a lot of money so have been a bit dubious about getting the device in case it a waste. Do you know this works? Please advice.

    • I wish I could give you a definitive answer. An Oximeter is a tool that some people find of use. Will you? I don’t know. Personally, I rely on tracking my diet log and symptoms and that’s something I help others do in Face Readings. Either way, good luck.

    • Hi Linda

      How about a used one?
      I got an older simple pulse clock similar to a fitbit tracker. It does, what it is supposed to: shows the pulse on the display. The price was 1 buck, since I was able to pick it up yesterday.
      Good luck

  8. Just tried this on myself, because I think I may be sensitive to dairy. Milk and Heavy whipping cream both gave me quite a jump, however a baby bell cheese did not. Is it possible to be sensitive to the liquid only versions of dairy?

    • Good work. Yes, people can respond differently to the various forms of dairy. So do keep experimenting to clearly identify which forms work for you.
