Specific dietary modifications have not been studied for sinusitis. However, some researchers propose that increasing foods high in polyphenols, such as ginger and green tea, may reduce inflammation and mucus production and therefore moderate symptoms in sinusitis. Following an anti-inflammatory diet, and avoiding refined sugars and processed foods (high in artificial colors, preservatives, histamine) may be helpful, as they may increase inflammation and exacerbate sinusitis symptoms.[1][2][3] Also, because milk allergy is common in chronic sinusitis, its intake can worsen symptoms in some people.[4]
