Identifying Your Food Sensitivities:
Food allergies and food intolerances are two types of food sensitivities that can be very destructive to the body. Food allergies are a very severe immune reaction to a particular food that causes immediate reactions such as swelling, rash, itchiness and sometimes a life-threatening anaphylactic shock.
Food intolerances cause more subtle health challenges that make someone feel uncomfortable without outward immune reactions. Food intolerances can often lead to elevated levels of whole body inflammation that can cause fatigue, joint pain, brain fog, digestive disturbances, headaches and other unwanted symptoms (1).
Many people go through their lives without ever understanding how food intolerances can lead to these health challenges. They never suspect that the food they are eating every day is silently killing them and their doctors never advise them to look at how they are responding to their diet.
The Massive Increase in Food Sensitivities:
True food allergies are estimated to affect about 4% of adults and over 5% of children these days. Clinicians and researchers are concerned about the increase in allergies in children over the last 20 years. There has been an 18% increase in food allergies in children since 1997 (2).
Over 25% of the population has subjectively reported that they have food intolerances and due much better when they avoid consuming certain foods.
The most common food allergens and intolerances are dubbed “The Big 8.” These include
1. Wheat (or all gluten products including barley, rye, kamut and spelt)
8. Tree Nuts
It is advisable for people to avoid gluten, unfermented soy, peanuts and pasteurized dairy as the health risks far outweigh any health benefits from these foods.
As a clinician, I see so many individuals that have food intolerances and sensitivities that cause an inflammatory spiral and worsening health. This is primarily caused by damage to dysbiosis or bad balance of microorganisms in the gut and resulting leaky gut syndrome (3, 4).
This leads to food particles entering into the circulatory system and the immune system tagging and creating an inflammatory response in reaction this. The body then becomes hard-wired to create inflammation every time we consume a particular food (5, 6).
Testing Your Sensitivity:
If you have a food intolerance or sensitivity than the food will cause a stress response when you consume it. This is because the body has identified it as a threat to your body and will initiate a mild-moderate immune response when it is consumed.
When the body is under stress, it activates the sympathetic branch of the autonomic nervous system. This signals a fight or flight response where the heart rate goes up, the blood pressure goes up, etc.
Understanding this fight or flight response, you can use a simple pulse test that uses biofeedback as a free non-invasive test to measure your level of sensitivity. There are number of food sensitivity tests that you can have done as well if you want to spend the money and have something more in-depth. I recommend this one here.
How To Perform the Pulse Test:
In order to do the free biofeedback test, begin by sitting down and relaxing for a few minutes and then take 3 long deep breaths and afterwards begin testing your resting pulse and get a number. Let’s say it is 60 beats per minute (bpm).
Next take 3 long deep breaths again and take the food in question and place it on your tongue and let it sit there for 20 seconds or so and do relaxed breathing and then test your resting pulse again while in the same position. There should be no other variables that would affect your heart rate.
Step 1: Sit down and relax for 5 mins
Step 2: Take 3 long deep breaths
Step 3: Test 60 second pulse rate and record
Step 4: Take 3 long-deep breaths again
Step 5: Put food item in question on your tongue and wait for 20 seconds
Step 6: Record pulse with food item still on your tongue
Step 7: Check the difference between normal heart rate and food item challenged heart rate.
The food elicits no response or just a 1 bpm difference in your heart rate. If you eat a certain food and it does not elicit a change in heart rate you are probably not sensitive to it. However, if you notice that you feel awful every time you eat it…then try avoiding the food and see what you notice instead. This is always a good general rule.
Gray Area Response:
The food elicits an increase in your heart rate of 2-3 bpm. Always retest if this happens.
The food elicits a heart rate increase of 4+ bpm. Stop and retest. If this happens again the food in question is causing a stress response and you should avoid this food for at least six weeks before trying again.
Frequently Asked Questions:
- Why do you take long deep breaths before each pulse recording?
A: You want to be in a relaxed state and take out as many variables as possible. It is easy to have a stressful thought or to talk or do something that would naturally bring up your heart rate. Taking 3 long-deep breaths helps restart your physiology in a relaxed, parasympathetic dominant state.
If you didn’t feel right about the test and felt as though you weren’t fully set for the challenge than, by all means, retest. The key is that you have as much standardization and accuracy as possible when doing the testing.
- Why do you put the food on your tongue? Why not just eat it?
A: Many practitioners do have the individual eat the food. If so, be sure to wait one full minute before retesting pulse. The act of chewing and swallowing can bring up the heart rate and cause a false positive.
Additionally, chewing and digesting a food you are sensitive too can cause an increase in inflammation ranging from very mild to very severe. Putting the food on your tongue for a minute and 20 seconds, won’t have quite this effect. I would prefer my clients to avoid this potential inflammatory storm if possible.
Steps to Take:
Once you have identified any major food sensitivities you will want to be sure to avoid these foods. If you continue to consume them they will lead to further destruction of the gut membrane, adrenal burnout and chronic symptoms and accelerated disease development.
You may be able to reintroduce some of these foods once your gut is healed and your immune system has calmed down. Begin following the SuperCharged Energy Diet while avoiding your particular sensitivities and incorporate the intermittent fasting strategies with fermented foods and probiotics to restore tone and balance to the digestive system.
What Dr Jockers Teaches:
I have most of my auto-immune clients begin on an auto-immune diet that eliminates the most common food sensitivities including the list above as well as nightshade vegetables (tomatoes, potatoes, eggplant and bell peppers).
I then have them do this pulse test with the other foods they will be consuming from this shopping list until they feel confident that these foods are tolerable. I then have them follow this diet for 30 days and then begin to retest certain foods.
I often will request a good food sensitivity lab panel which lets us know what sort of reaction people have to most foods. You can see this test here
Millions of Americans have digestive problems that fall into the catchall of IBS, but what they don’t realize is that most cases are caused by a little-known condition called SIBO—Small Intestinal Bacterial Overgrowth.
The result is pain, bloating, and digestive distress, ultimately leading to other long-term diseases. Sound dreadful? It certainly can be.
SIBO awareness is so new that most doctors don’t have it on their radar. This leaves people suffering and misdiagnosed for years. But one SIBO patient is fighting to change that.
There’s someone I’d love for you to meet—her name is Shivan Sarna and she has an incredible story of dealing with SIBO. Shivan is a total powerhouse, inspiration, and a host for one of the top ten TV networks.
She’s also the host of the SIBO SOS™ Summit, an online conference that brings together over 30 SIBO experts and patients stories to cut out the confusion and share the most current treatment options and recommendations.
The summit is free to attend. You can register here for The SIBO SOS™ Summit Part II.
I can tell you right now, this summit is an incredible resource to anyone dealing with SIBO or IBS. If you’re looking for the most current and in-depth info out there, you’ll definitely want to learn from these experts.
There is a lot of hope for those with SIBO!
