Food intolerance, also known as hidden food allergies, occurs when the immune system produces Immunoglobulin G (IgG) antibodies in response to certain foods. Unlike immediate food allergies, which appear shortly after eating, hidden food allergies develop slowly over time. This delay often makes it difficult to identify which food is causing the reaction.
Hidden food allergies involve the body gradually forming IgG antibodies against specific foods. These responses do not appear instantly, allowing symptoms to accumulate subtly over days or even weeks.
When consuming a food that triggers intolerance, white blood cells produce antibodies that bind to the offending food. Instead of being absorbed normally, the food–antibody complexes create inflammatory particles that circulate in the bloodstream. These particles cause inflammation in different parts of the body, leading to varied symptoms depending on each individual’s sensitivity.
Testing identifies IgG antibodies reacting to specific foods. This helps determine which foods should be avoided, reduced, or rotated. The results support planning alternative diets and identifying when certain foods may be safely reintroduced.
Hidden food allergies may develop due to:
Genetic predisposition
Weak gut immunity
Inefficient digestion or poor nutrient absorption
Imbalanced gut microbiota
Overgrowth of pathogenic bacteria or yeast
Leaky gut from reduced beneficial bacteria, often caused by frequent antibiotic use
These issues allow undigested particles to enter the bloodstream and trigger immune reactions.
