Brief Summary

Previous studies on the association between the development of allergic diseases and diet indicate the involvement of dietary fatty acids (FA) in the acceleration and/or inhibition of allergic diseases. Edible oils contain various FAs, but their composition depends on the materials from which they are extracted. FAs are characterised by the presence or absence of a carbon double bond in their structure; saturated FAs (palmitic acid, stearic acid, etc.) have no carbon double bond, while unsaturated FAs contain at least one carbon double bond. Among the unsaturated FAs, omega-3 FAs (such as alpha-linolenic acid \[ALA\], eicosapentaenoic acid \[EPA\] and docosahexaenoic acid \[DHA\]) and omega-6 FAs (such as linoleic acid \[LA\] and arachidonic acid \[ARA\]) are classified as essential FAs. Various types of bioactivity of dietary essential FAs have been reported in health and disease studies, including immunity, allergy and inflammation. Human studies, for example, have shown an association between the quality of dietary FAs and the incidence of allergic diseases. Translated with DeepL.com (free version)

Outcome Measures

Primary Outcomes (3)

  • Endoscopic evaluation

    Endoscopic evaluation of the nose using the Lund-Kennedy (LK) score.THe LK scoring system is based on the degree of polyps, discharge and edema in each nostril.

    From the enrolment (T0, baseline, diagnosis) to T1 (90 days after the diagnosis and treatment start)

  • Symptoms and quality of life evaluation, VAS

    Symptoms and quality of life evaluation using the Visual Analog Scale (VAS, range 0-10; \>5= uncontrolled disease)

    From the enrolment (T0, baseline, diagnosis) to T1 (90 days after the diagnosis and treatment start)

  • Symptoms and quality of life evaluation, MiniRQoLQ

    Symptoms and quality of life evaluation using the Visual Analog Scale (VAS, range 0-10; \>5= uncontrolled disease) and Mini Rhinoconjuctivitis Quality of Life Questionnaire (MiniRQoLQ, which utilizes a 7-point scale for each of its 14 questions, ranging from 0 (not impaired at all) to 6 (severely impaired), ranging 0-84).

    From the enrolment (T0, baseline, diagnosis) to T1 (90 days after the diagnosis and treatment start)
