It has previously been unclear and poorly documented, on additives in food can trigger rhinitis in individuals without atopic allergies. Therefore, Italian Researchers investigated 226 people with rhinitis, but without atopic allergy.

The subjects got first in one month diet free from substances full of additives such as sodium benzoate, etc. Then got the diet with these substances. In the period without additives approximately nine percent of participants had milder symptoms, and about three percent were completely symptom free.

When they were exposed to sodium benzoate, responded about 20 percent with, head cold, stuffy nose and itchiness in the nose. The researchers believe their study shows that a repeated, daily intake of small quantities of additives can give some people rhinitis.
