Probiotics are substances which can keep harmful bacteria under control. Probiotics are found in foods like pickles, yogurt, unpasteurized miso, and kimchi. Include these foods in your diet to help get the infection causing bacteria under control.   Pickles can be eaten as a side dish with a steak, for example. They're a very convenient food to pop in as a snack when you're on the go, too. Eating a cup of fruit with a serving of whole grains, such as granola or oatmeal, in the morning can make a great nutritious breakfast and will provide you the necessary amount of probiotics to fight off future infections. Vitamin D is a great immune system booster. It stimulates the body into having a faster response to pathogens such as the bacteria causing your sinus infection. The best way in which you can get a fair amount of vitamin D is through sun exposure. A walk outside on a sunny day will do the trick.  Vitamin D isn't really found in food. You can take a supplement, but you may wish to talk to your doctor before doing so. Supplements aren't appropriate for everyone. Antioxidants reduce cell deterioration by neutralizing free radicals. If the cells suffer less damage, the body can fight infection a lot easier. Berries (all kinds), beans, kiwi, acai, apples, and pecans are all great sources of antioxidants. A great antioxidant is vitamin C. It's found in a lot of foods, like citrus fruits, lemons and peppers. It’s easy to incorporate these foods in your diet, too. You can use the juice from a lemon by adding it to your salad, for example, or add a bit of pepper to your soups, stews, or even sandwiches. Foods that are sources of vitamin A strengthen the immune system and prevent the onset of respiratory disorders. The best sources of vitamin A are generally found in vegetables, which are good for the rest of your health, too. The best vegetables for sinusitis include:  Green leafy vegetables Carrots Beets Spinach Some people may have a food allergy or food sensitivity that causes excess mucus production, or might even compromise their immune function, leaving them more susceptible to infectious agents. Could this be you? If you're unsure, an elimination diet is a good way to test yourself for food sensitivities.  With this method, you deliberately eliminate specific foods to see if your health improves when you don't eat those foods. After a specific period of avoidance (typically 7-14 days), you reintroduce the suspected food into your diet and see what symptoms, if any, you experience. If your sinusitis is an effect of allergy, you should be able to identify the allergen in this manner and get rid of it forever.
