Foods to beat the cold and nasty flu

During the cold season, it gets darker earlier and there is limited exposure to sunlight. This reduces the levels of hormone serotonin responsible for mood boosting which can lead to depression. Depression can weaken immunity and consequently increases the risk of infections. Reduced exposure to sunlight can cause vitamin D deficiency which is key in strengthening the body’s ability to fight infections. Colds and flu viruses are thought to better survive in cold climates.

Even though diet can’t solely prevent an infection, good nutrition is essential to the development and maintenance of a healthy and strong immune system which can help the body fight infections and minimise the duration and severity of an infection. Vitamin C has anti-bacterial and anti-inflammatory properties that help the body fight infections; it also acts as an antioxidant to help cells against harmful compounds formed in response to viral and bacterial infections.
