Historically, country dwellers were most at risk of contracting Hayfever, but now it is twice as common in towns as it is in the country, mainly due to vehicle pollution and the effect of sunlight on it (petrochemical smog as it is known)
It affects 20% of the population with the peak age being twenty for contracting it
It is estimated that Chronic Rhinitis affects 1 person in 6. Itching of the nose suggests allergy. Non-infectious, non-allergic rhinitis can be diagnosed by exclusion, and usually there are food allergic components in that condition. Rhinitis can be provoked in some people by oral contraceptives, aspirin, pain-killing drugs (the non-steroidal anti-inflammatory drugs), or the dye tartrazine
There are specific nutrients that help protect us from this condition, and there are certain foods that aggravate it and some that help protect against its symptoms
