Determine Food Sensitivities: At Home!

Have you ever suspected you're sensitive to a particular food? Or maybe you experience digestive issues, have a chronic illness, allergies, skin irritations, headaches, or achy joints and you've never been able to pinpoint exactly what is causing the issue.

There is a really good chance you're sensitive to a food you commonly eat and just don't realize it because you do not have a marked immediate reaction. I often hear from clients "I feel fine when I eat [insert inflammatory food here]." The only problem is that their body may be telling a different story.

I have a secret to share with you... you can actually TEST YOUR BODY on a particular food at-home - and it's totally free.

It's simple! Conduct the Pulse Test developed by Dr. Arthur F. Coca. Outlined below is a simplified variation of the test I use in my practice with clients to determine food sensitives and histamine reactions in the body. In practice, I'm able to be a little more accurate when testing you - but the steps below will still give you a good idea if you're sensitive to a food.

HOW IT WORKS: When you eat a food you're sensitive to your body is placed in a stressed state. When you are stressed, your pulse increases. This test catches the spike or dip in your pulse if a food is a potential issue for you creating a spike of histamine in the body.

COMMON FOODS TO TEST: Various types of dairy, glutenous grains, coffee, nuts, nightshades, sugar, chocolate.

NOTE: Testing one-ingredient foods are best (cheese, almonds, coffee, flour, sugar, etc. - as opposed to multiple-ingredient foods like bread, pasta, prepared latte, etc.), otherwise you wouldn't know which ingredient you're reacting to.

Also, be sure to begin the test on an empty stomach - no food or drink (besides water) for at least 2 hours prior.


  1. Sit in a rested state, take your pulse for a full minute. This is your base rate, record it.
  2. Take a bite of food, chew it, but don’t swallow it, and hold it in your mouth so that you can taste it for 30 seconds.
  3. With the food still in your mouth, take your pulse for a full minute again, record it.
  4. If your pulse changes by 6 points or more, spit out the food, and rinse out your mouth. If it doesn't change you're fine to swallow the food.
  5. Wait 2 minutes before trying another food, or until your pulse has returned to its base rate (always obtain a new baseline before testing a new food).

WHAT DOES IT MEAN: An increase or decrease of 6 beats or more indicates the food tested is causing stress or a histamine reaction in the body. Moving forward it's best to avoid that food until you're able to work on your digestion, detoxification, and over all wellness. This doesn't mean you can never have that food again, however it does mean you need to remove it to allow your body to heal.
