Causes of Sinus Infection
According to Pub Med Health, viral, fungal or bacterial infection can cause sinus infections or sinusitis. Anything that blocks the normal drainage of the sinus cavities, including allergies, can predispose you to developing a sinus infection. Strengthening the immune function through good nutrition, including fruits and vegetables, can help the body to fight off foreign substances.
Fruits high in antioxidants and flavonoids include blueberries, blackberries, raspberries and strawberries. Load up on fresh in-season berries during summer. Other antioxidant-rich fruits include kiwi, red grapes and cranberries. Antioxidant-rich foods can remove free-radicals that cause oxidative damage to your body and lead to disease and infection.
Great anti-inflammatory fruits include papaya and pineapple. Papaya contains vitamins C and E as well as papain, an enzyme that aids in the digestion of protein and reduces inflammation. Pineapple contains bromelain, a natural antihistamine and anti-inflammatory agent, which can help to liquefy mucus build up and reduce swelling throughout the body, including inflammation of nasal sinus passages.
Avoid Problem Foods
Many foods produce mucus and promote inflammation and the allergic response. You may find it beneficial to remove some of these problem foods. Foods such as dairy, gluten, alcohol, coffee, sugar, soda, white flour and processed foods can contribute to sinusitis symptoms, promoting an environment where infection can thrive. Keep the body hydrated by drinking plenty of water to help keep mucus membranes moist and enable them to remove foreign particles.
