Vitamin D is essential for proper immune function and salmon happens to be one of the few food sources that pack a healthy dose of it—especially wild-caught salmon. Just half a fillet of sockeye salmon (198 grams), there is 815 IU (international units) of vitamin D, per the USDA. For context, the National Institutes of Health (NIH) recommends that the average adult consume between 600-800 IU of vitamin D daily. Still, several studies suggest consuming at least 1,000 IU of the vitamin each day for optimal health. In fact, you can safely consume as much as 4,000 IU of vitamin D daily, which may be especially beneficial for those who live in areas where there isn't as much sunlight.

When you're looking for a good that's rich in omega-3 fatty acids, look no further than salmon. Salmon is rich in docosahexaenoic acid (DHA), which is a type of omega-3 fatty acid, which is believed to reduce blood triglycerides and even harmful LDL cholesterol particles. In addition to keeping your heart healthy, omega-3 fatty acids provide a host of other health benefits. As Sydney Greene, MS, RD, and member of our medical board explained to Eat This, Not That! in a previous article, "Omega-3s make up the structure of cells in our body. We also need them for hormone production, immune function, and heart and lung support."

Finally, salmon also contains magnesium, a mineral that plays a key role in supporting your immune system. For reference, men need between 400-420 milligrams of magnesium each day whereas women require 310-320 milligrams of the mineral each day. A 3-ounce serving of farmed Atlantic salmon contains about 26 milligrams of magnesium, per the Cleveland Clinic. While this may not seem like a lot, if you pair it with a 1/2 cup of brown rice and avocado slices, you then add an additional 86 milligrams of the mineral to your meal.
