6 Immune-System Boosters For Cold and Flu Season

There are various ways you can get influenza or the “flu” as it is usually called. One common way of contracting this infectious viral illness is through airborne transmission. Another is coming into contact with an infected surface.

Although a flu shot is the best defense against viral infections like influenza, it still does not fully protect you from the illness. Some people still experience the hallmark symptoms of the influenza virus like headaches, nausea, fatigue, and chills during cold and flu season.

Influenza usually lasts one to two weeks (it can linger much longer in some cases). Aside from strengthening your immune system, the best way to avoid getting sick this season is to practice preventive care.

Below are some actionable steps you can take every day to protect yourself from getting sick with the flu.

6. Avoid Processed Foods

Aside from helping in protecting you from the flu and other viruses, eating foods high in antioxidants like fruits and vegetables will boost overall health. Nutrient-rich foods like dark leafy greens, salmon, sweet potatoes and berries have anti-inflammatory properties that improve your immune system’s defenses. Avoid processed foods, sugar and gluten as they can decrease immune function.
