Food intolerances and how metabolic types react to specific foods play an important role in many of the live blood anomalies. While we are not usually able to tell specific food sensitivities from what we see in a live and dry blood sample, we can see very clear indications that there are food intolerances affecting a client by analysing their live and dry blood. In these cases we usually eliminate the most likely foods from the diet and reassess to see whether the anomalies have improved. It would be possible to test a person’s reaction to a specific food by looking for a negative reaction after they consume the food, but they would need to be very sensitive to the food for the reaction to be obvious. In most cases it’s more practical to eliminate foods and to then look for an improvement in the intolerance indicators.
