Complex carbohydrates, such as sweet potatoes, whole grains, beans and other and legumes, are good for your immune system because they help keep your gut healthy.
Your gastrointestinal (GI) tract is one of the most important parts of your immune system. It acts as a physical barrier to prevent pathogens from entering your bloodstream.
In order for your GI tract to do its job well, it requires an appropriately balanced microbiome.
To help keep those microbes in balance, it’s important to selectively feed the good "bugs".
Complex carbohydrates are an excellent source of prebiotics, specific types of fiber that the good bacteria in your gut enjoy.
Sources of prebiotics include oats, barley, bananas, onion, garlic, chickpeas, leeks, and lentils.

Fermented foods have been consumed in nearly every culture around the world for thousands of years.
These foods are cultured with beneficial microbes, such as lactic acid bacteria that help preserve the food while improving the health of the humans that eat it.
Regular intake of foods fermented with lactic acid bacteria, like yogurt, can lead to improved gut microbiome balance, reduced risk of infection, and even improved tolerance of lactose.
Fatty fish are an important source of omega 3 fatty acids (omega 3's), an essential fat lacking in the diet of many.

Increasing these healthy omega 3's and lowering omega 6's can help you stay healthy.
Other good choices include sardines, trout, tuna, oysters, and shrimp. Look for sustainably sourced and wild-caught fish, as these will have the best omega 3 profile.
You can also take a high-quality omega 3 supplement.
These are only a few of the many foods that can have an incredible impact on our lives!
So the next time there is a cold going around, give your immune system a chance to fight back with a careful diet.
