Today I’m going to share a simple DIY allergy test. This is primarily for food allergies that you can't quite determine. 

During an allergic reaction, your pulse increases. A pulse oximeter is a great tool to help you check your pulse easily, but you can also check your pulse using your wrist or carotid artery. 

How to do a DIY allergy test: 
1. Check and record your pulse rate:
• In the morning, before getting out of bed
• Before eating
• 30 minutes after eating
• 30 minutes after that 
• 30 minutes after that 
• Before bed

2. Record what you ate next to your pulse rate 

Typically, you could have an allergy if there is a difference between the low and high pulse rates above 16 points. The pulse rate also needs to be above 84. 

If you react to a meal, use this test over a few days, eliminating foods one at a time to help you isolate which ingredient is causing a problem.

    The scare to demonize eating fish and eggs is an absolute myth! 🙂 Anxiety will increase pulse rate. Thank You Dr. Berg for helping to truly save people! 💯

    I think your heart goes up regardless because you’re digesting. If you have a smartwatch you can learn a lot about your heart’s behavior by watching it through activities. For example, if you have to pee while you’re sleeping, your heart rate will increase to wake you up, then decrease as you release the urine. Once you realize what’s normal for you, you can watch your heart rate to determine if you’re low or running low on an electrolyte. I found that I was taking too much electrolytes at one time and not spreading them out over the course of the day. I fixed that. You can also notice your heart rate drop almost immediately following taking magnesium supplementation. If you have or had mold in your home, you can tell if mycotoxins are present as your heart rate will be elevated while you’re in the home. Smartwatches are worth the investment and the heart monitor alone has alerted me of medical issues along with the ECG…..once main stream smart watches release blood pressure technology it will be a game changer.

      but what about blue tooth dangers?

    • Carlos Ruiz on April 19, 2023 at 12:11 pm

      @Ginger&Garlic I’m not that concerned. My watch is rarely near my head or vital organs.

    • Ginger&Garlic on April 19, 2023 at 12:55 pm

      @Carlos Ruiz ok thanx

    • Itza Mystri👻 on April 19, 2023 at 4:45 pm

      That’s fascinating, thanks for the insight

    • Ian Stuart on April 19, 2023 at 5:20 pm

      @starflower666  Very valid concern not to be casually dismissed IMO!

  5. Bill Bauer on April 19, 2023 at 11:10 am

    Dr. Berg, my mom was diagnosed with Polymyalgia Rheumatica. Her pain was relatively mild, but getting worse. The standard treatment for it is taking high doses of Prednisone for about 2 years. This has the almost inevitable side effects of diabetes, osteoporosis, and many other serious diseases. Luckily we saw your video that stated that one can use Vitamin D to reduce inflammation, and that Vitamin D is a steroid that is somewhat of an alternative to Prednisone. My mom has been taking 30,000 IU of Vitamin D (with 300 mcg of Vitamin K) for about 2 months. Her pain has mostly gone away, and her ESR levels had come down (albeit they are still high). Her blood Vitamin D levels have been increasing and are now 390 nmol/L (my understanding is that officially the toxic level is above 500 nmol/L). However, as a result of her taking Vitamin K, her calcium levels are still normal.

    She tried reducing the daily amount of Vitamin D she was taking, and her symptoms had returned. She increased the daily amount, and the symptoms went away again.

    It looks like therapeutic levels of Vitamin D cause the blood levels to approach the supposedly toxic levels, however with Vitamin K (and Vitamin A?), the Calcium levels remain normal.

    I hope you can make another video where you discuss what one has to do when one takes those high doses of Vitamin D for extended periods of time. Is it the case that as long as the Calcium levels remain normal, one doesn’t need to worry about the blood level of Vitamin D?

    • pg on April 19, 2023 at 11:58 am

      I think you answered your question . As long as calcium levels are normal i think your fine !!!!!

    • willothewispl on April 19, 2023 at 12:15 pm

      I am deficient in vitamin D.,So my Dr gave me D3 but I cannot tolerate it. Bought D3 liquid drops to try. Supposed to be better. Had to buy from a health food store.

    • wiz on April 19, 2023 at 1:04 pm

      @willothewispl When doctors prescribe vitamin D it’s usually vitamin D2.

    • Lorrieonline on April 19, 2023 at 1:29 pm

      Pretty sure Dr. Berg pointed out in one of his videos that for every 5,000-10,000 iu of D3, we need 100mcg K2-M7. So glad you posted your remarks. I may up my levels as well, knowing how much good it has done your mom.

    • Awesome kids on April 19, 2023 at 3:06 pm

      @wizI wonder why they kept prescribing D2 instead of D3 when they know it wouldn’t help.

    Good Morning, Dr Berg 🌞
    Thank you so very much for sharing this great Information with us God bless you all 🙏

    This does not necessarily indicate a food allergy. A rise in heart rate after eating can be Roemheld Syndrome (AKA Gastricardia). If you get cardiac symptoms related to your gut then you should look deeper into it. I would ay this could be accurate of you pay attention in general. If it only happens with a certain one or two foods, then maybe it’s an allergy or sensitivity. If it happens regularly it may be Roemheld. I have seen my pulse go from being 82 BPM to 120- 172 BPM after eating. That’s obviously a severe episode, but you get the idea.

    • Susan Scavelli on April 19, 2023 at 4:55 pm

      Yes yes yes. My drs could never figure out why I had cardiac issues. All cardiac tests were normal many many years. One gastro dr said I had gastritis and also mentioned with eating it could be the cause! I paid attention to this and found it to be the case. Also one must decipher between stress/anxiety issues for this as well! Excellent comment

    • Betty Austen on April 19, 2023 at 5:13 pm

      @Susan Scavelli how are you now?

    • The Patriot's Kitchen on April 19, 2023 at 5:54 pm

      @Susan Scavelli I hope you’re doing better now! It can be a real struggle sometimes.

    What’s amazing for me personally is that as I was growing up in Zimbabwe I never had any known allergies. Moved to the States when I was 17 and all of a sudden I had allergies galore and lactose intolerance to boot. Moved back to Zimbabwe when I was 35 and all the “allergies” I had were gone.

    • Dominique Baptiste on April 19, 2023 at 3:03 pm

      This makes me feel sad for people in America. I hope we come together and create a healthier more sustainable system. There are massacre of dead fish off the gulf of Mexico from the run off of these farms. Of pesticides and whatever else of the agriculture of food.

    • Ian Stuart on April 19, 2023 at 5:15 pm

      @Tumbleweed UK Highy probable explanation, good work!

    • Jen WILL on April 19, 2023 at 7:08 pm

      I met a family from Togo and they were very beautiful and healthy. The children and teens’ skin was without acne, and they were all slim and fit.

  9. sarah Brownell on April 19, 2023 at 12:21 pm

    I had reactions to so many foods but all tests negative for years. Had all the symptoms too. It’s more after eating it when it digests. My thyroid grew nodules and my body went crazy with allergies. Had removed and most are gone but not all! Good test to see what foods bother me!

  10. MandiSmash on April 19, 2023 at 1:20 pm

    A thing I found out recently is that I seem to be allergic to cobalt. I thought for a long time I had an inconsistent allergic reaction to shellfish, but I don’t — cobalt is contained in certain foods like shellfish and so it was hard to really figure out the pattern.

  11. Healthy and Loving Life on April 19, 2023 at 1:26 pm

    My husband has palpitations that have not completely gone away with beta blockers. He also takes magnesium and potassium daily. He wants to come off of the beta blockers because they make him feel blah so this may be the answer to our prayers! He noticed the other day that he had not had palpitations and then after eating a scoop of peanut butter, he had a few. That’s what led me to look into food allergies and then this video came at the perfect time!! Thank you Dr. Berg!

    • Charlotte Buck on April 19, 2023 at 3:16 pm

      You can also check what other vitamins beta blockers deplete just to be on the safe side

    • Healthy and Loving Life on April 19, 2023 at 3:56 pm

      @Charlotte Buck Ooh, good idea!

    • Healthy and Loving Life on April 19, 2023 at 4:00 pm

      @Charlotte Buck  I googled it and they can deplete magnesium, sodium, potassium, zinc, pyridoxine, thiamine, and ascorbic acid. He takes all of these in some form except for pyridoxine. Will look into that further. Thank you for that tip!

    • ZombieGoesBoom on April 19, 2023 at 4:31 pm

      @Healthy and Loving Life that’s interesting, while i had palpitations and had beta blockers, my potassium was low! The doctor just gave potassium supplements but didn’t mention anything else

    • Healthy and Loving Life on April 19, 2023 at 4:49 pm

      @ZombieGoesBoom  Yeah I think when one electrolyte value is off, it affects all others but I didn’t know about the thiamine and pyridoxine.

  12. maurice houghton on April 19, 2023 at 1:45 pm

    So simple and original. I have multiple allergies. This will certainly help to identify them. Thank you sincerely. 😊

  13. Abdul rashid paracha on April 19, 2023 at 1:46 pm

    Amazing. So accurate diagnosis. I totally with you my great doctor. Stay blessed

  14. Robin Hood on April 19, 2023 at 2:31 pm

    I already did a simple test to find out why so many people thesedays are getting allergies and which was initially brought to my attention by the sheer numbers now suffering from the most repulsive and grotesque skin rashes over their arms, legs and even neck and torso. So I decided to follow these people in order to determine at what point these horrendous rashes would break out, and BINGO! It was everytime they came out of a tattoo parlour! 🤣

  15. Awesome kids on April 19, 2023 at 2:59 pm

    My child heart rate once went up to almost 180, took him to urgent care and his pediatrician but they had no idea why, even though they had on record that he had multi food allergies. I used the oxygen pulse rate meter ever since. Took me awhile to figure out all of his many weird and delayed symptoms and all the food allergies that he had all by myself just by observed him and kept food record. I couldn’t trust the doctors anymore. I also tested by putting a small allergen on the skin and bandage it and leave it on. Thank you for your confirmation Dr. Berg.

  16. Ryan C on April 19, 2023 at 3:22 pm

    I did an allergy prick test years ago which led me to and e.o.e diagnosis. Wish they were just regular allergies, nice to know a quick way to do it now 👍

  17. Amie Hegeman on April 19, 2023 at 4:12 pm

    So I think I heard Dr. Marik mention your name on Dr. Been’s video. (2mos ago Metabolic Syndrome Defined..). Man, if all of y’all joined forces, that would be amazing. All 3 of you have made such a big difference in my life and health! 💕

  18. Janet Lombardi on April 19, 2023 at 4:23 pm

    I don’t know what my allergy is, but I get an awful irritating itch all over my body. It’s time for an allergy test, I think. 😊

  19. SavedGasMan27 on April 19, 2023 at 4:46 pm

    Heart rate went up for YEARS after eating chocolate candy bars. It got worse as I got older. Sore throat body pains after eating chocolate cake. Went to my integrated medicine practitioner and she said it sounded like I am allergic to chocolate. The test came back showing I am allergic to chocolate. I ate chocolate for years. 🤦🏽‍♂️

  20. Leah Bresee on April 19, 2023 at 6:09 pm

    It’s interesting that no mention was made of the level of physical activity around the times of taking the heart rate. Resting rate vs simply walking around is usually different.
