Infection is caused by bacteria, fungus and viruses. While food itself cannot cause infection, your diet can influence the health of your sinuses. Certain foods can cause inflammation, sinus irritation and allergic rhinitis. If you experience chronic sinus infections, talk to your doctor about ways to reduce sinus infection.
Infection
A sinus infection is caused by a fungal, viral or bacterial infection, according to MedlinePlus. These types of germs can invade your sinus cavity by inhaling them or by touching a contaminated surface and then touching your nose. When your sinuses become blocked or too much nasal mucus builds up, bacteria and other germs can invade your sinus cavity more easily. If you’ve ever looked up your nose in the mirror or looked up someone else’s nose, you will notice that tiny hairs, called cilia, line the nasal passageways. The job of nasal hair is to help filter or block out as many germs as possible to help reduce sinus infections.
Diet
Depending upon your immune system, you may develop allergic rhinitis, which can be triggered by certain foods, according to the University of Maryland Medical Center. Allergic rhinitis is inflammation of the nasal cavity caused by allergies. Other foods, that you may not be allergic to, can cause post-nasal drip. Spicy or hot foods, such as Buffalo wings, jalapenos and other types of peppers can cause post-nasal drip. Even foods that are not hot can cause post-nasal drip, such as onions. When these foods cause your sinuses to water and secrete additional mucus, it can cause sinus inflammation, which can make it easier for bacteria, fungi or viruses to invade.
Other Causes
Your diet isn’t the only thing that can make you more susceptible to develop sinus infections. Colds and other allergies, such as hay fever, pollen, mold and dust mites can also leave your sinus cavity inflamed and more susceptible to infection. Smoking, tooth infections and a weakened immune system can also make you more prone to developing a sinus infection, according to MedlinePlus.
Reduce Inflammation
To avoid an increased risk of sinus infection, there are some measures you can take at home to help reduce sinus inflammation. Always consult with your physician prior to trying at-home remedies and seek medical attention if the nasal mucus begins to turn green in color, which can indicate infection. Drink plenty of fluids to help thin mucus. A humidifier may help reduce the dryness in the air that you breathe in; thus, reducing sinus inflammation and irritation. A nasal spray may also be useful. Follow the instructions on the nasal spray packaging or use as directed by your physician. If you experience sinus pressure or sinus headache, avoid bending forward with your head down. An over-the-counter pain reliever or anti-inflammatory medication may also be useful such as acetaminophen or ibuprofen may also help alleviate sinus pain and pressure.
