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.
