The Coca Pulse Test
In the 1950s, Dr. Arthur Coca identified that his wife’s heart rate would increase if she ate a food to which her body reacted. Coca tested his patients as well and found the results effective and consistent.
Though there are blood tests and other faster ways to determine food sensitivities, this approach remains one still used today because of it's effectiveness, low cost, and ease of application for people who want to self-diagnose.
The Initial Test
Take your pulse during these times for three days:
Your morning pulse should be the lowest of the day. Unless you are allergic or reactive to something on which you are sleeping. (Pillow, fabric softener, sheets, carpet, dust mites, pet that sleeps with you, etc.)
If your pulse goes up noticeably after you get up from bed, you could be reacting to something like your toothpaste, shaving lotion, shampoo, or make-up.
Determine your highest and lowest pulse rates over the three days. Your highest "non reactive" pulse rate should be no more than 15 beats above your lowest point. Anything above that point is questionable and mostly likely an indication that you are having a reaction. So, if your lowest point is 60, then anything above 75 is a red flag.
Pinpointing the Cause of the Reaction
Start with the times you saw the highest pulse rate increase, especially if it was immediately following your meal. Determine every item in the meal you ate.
Isolate each food from that offending meal to determine which one is causing a problem.
You will now single test each of those items to determine a reaction over a two or three days period by snacking on each foods seperately throughout the day.
Eat a small portion of food every hour. For example, if the meal you are testing was an egg sandwich, you will test the following items:
Take your pulse just before eating the food and 30 minutes afterwards and note the results.
Even if you have a reaction, you should test all items in the dish as you could be reacting to more than one food. If you react to a food that contained spices or seasonings, you should then further eliminate by testing each spice or seasoning, as you could be reacting to them and not the food itself.
Dr. Coca emphasized the importance of applying yourself to testing over a number of days in order to identify which foods are making your pulse faster than normal and he believes his method to be a "roadmap to the fountain of youth."
