What is the difference between immediate food allergies and delayed food sensitivities?
Immediate allergic reactions (IgE) occur within a few moments to up to two hours, so it is easy to identify a correlation. Whereas delayed sensitivities happened from two to 72 hours after eating, sometimes even longer. This is why it is difficult to logically connect the symptoms with food just eaten. The reason for this is protein takes 3 to 4 days to enzymatically digest, so foods you eat today are added to the foods you have eaten over the last three days. There is a very high correlation between delayed food sensitivity and the amount and frequency of the food consumed.
Immediate allergic reactions (IgE, or Histamine) occur within a few moments to up to two hours after contact or ingestion, so it is easy to identify a correlation. Whereas delayed sensitivities usually happen within 2 to 72 hours after eating; sometimes even longer. This is why it is difficult to logically connect the symptoms with foods just eaten. The reason for this is proteins take up to 3 to 4 days to enzymatically digest, so the foods you eat today are added to the foods you’ve eaten over the last three days, which makes identification very difficult. There is a very high correlation between delayed food sensitivity and the amount and frequency of the food consumed.
