Pulse Test Instructions

This pulse test was first published in 1956 by immunologist Dr. Arthur Coca. It, is sometimes known as the Coca Pulse Test.

Test Procedure

  1. Wait at least two hours since you have eaten.
  2. You need to be relaxed for a few minutes before starting the test and throughout the test.
  3. Take your pulse for a full 60 seconds. We need a full minute because we don’t want any rounding errors. (Do not take it for 15 seconds and multiply by 4, or 30 seconds x 2)
  4. Put a piece of food in your mouth. Chew it for 30 seconds to 1 minute, but do not swallow any of it.
  5. Take your pulse again, for a full minute, with the food in your mouth but without swallowing any of it.
  6. Spit out the food
  7. Rinse out your mouth
  8. Let your pulse return to your baseline before testing another food.


If your pulse increased by 6 beats or more, you had a stress reaction to that food. Avoid it for at least a month, and then test it again.

Why it Works

When you taste a food, your taste buds will send a signal to your brain. If you eat this food regularly, your brain will recognize the food you are eating, and start a series of physiological processes. If your body has been consistently having an allergy, or a sensitivity to that food, your brain will start a stress reaction in your body. That stress reaction causes your pulse to increase.


Your body recognizes certain foods as being hostile to it. Normally, this is because of a condition called Intestinal Permeability, aka Leaky Gut. We will cover this in detail later in our class. In simplified terms, your small intestine is like a very tight-mesh net. When you digest food, you break it down into microscopically small particles.  These very small particles pass through the net and into the bloodstream. This is how nutrients get absorbed. Your immune system recognizes those nutrients as invited guests, so there is no adverse reaction. But, if you have a poor diet, your intestinal cells don’t have the building blocks they need to maintain their integrity, and your intestinal bacteria gets out of whack, those small holes can start to enlarge. Over time, they get big enough that undigested proteins can pass through the net and get into the bloodstream. Your body’s immune system recognizes these undigested proteins as uninvited invaders, and it attacks them. This is what causes the stress reaction, aka inflammation, in your body. We usually call these food allergies.


The good news is that you are on a program designed to remove the damaging foods and replace them with foods that feed your cells. Then, if you’re taking the recommended nutraceuticals, you are going to replenish the helpful bacteria in your gut. This will give your body what it needs to repair that mesh netting, so all the holes are small again. Once that happens, those undigested proteins won’t be able to pass through the small holes and into the bloodstream until they are fully digested. This eliminates the stress that we described above.


Often, food allergies go away once the body restores itself. That is why we want you to test the sensitive foods again after a month or two.


If you do your part, your body will be able to do its part, and there’s a good chance you will no longer be sensitive to those foods.
