What is the best way to test for food allergies?
There are three tiers of testing for food allergies. The most common but least accurate is blood testing. There is also skin prick testing, but this is uncomfortable but much more accurate than blood testing. And finally is a direct food challenge when the patient is given a particular food to eat to see how they respond.nnThe major problem with blood testing is that if leaky gut is present from bacterial overgrowth, the testing will often show an abnormal (often referred to as allergic) reaction to almost all the foods present in the diet. nnFortunately, the protocol helps the gut to heal, and leaky gut stops. Other than severe allergic reactions that trigger severe asthma or shock, food testing is not necessary.
