Olive oil and allergies

With allergy season upon us, there is more scientific evidence the olive oil polyphenols can act as barriers to allergens..."olive extracts have been demonstrated to act as antihistamines by blocking histamine receptors and thereby speculated to play a role in allergy". Most recent research has shown that hydroxytyrosol, one of the major elements of the phenolic components of olive oil, can modulate an allergen-specific immune response.
