Berries


Berries are a rich source of proanthocyanidins, which are potent antioxidants. One berry in particular, Elderberry has been found to inhibit viral binding to cells and reduce the severity and duration of viral infection such as influenza. Other berries such as blackberries, raspberries, blueberries and blackcurrants also contain cyanidins. Blackcurrant has been shown to inhibit influenza virus in in vitro testing and blackberries protect against inflammation of the lung pleura. A great start to a wintery morning is some organic oats with a mix of these berries on top!

Green Tea


Green Tea contains catechins and theanine which have been found to reduce the incidence of influenza infection amongst aged care workers. Green Tea catechins may affect enzymes found within the virus responsible for its binding and replication capability.

Mushrooms

shiitake mushroom help boost immunity

Medicinal mushrooms such as Reishi, Shiitake, Enoki, Maitake and Oyster contain long chain polysaccharides called beta-glucans which have been found to be potent immune enhancers. Beta-glucans stimulate white blood cells of the immune system involved in breaking down bacteria, and have an anti-inflammatory effect. Mushrooms can easily be added to stir fries, winter soups, pies, pasta and omelettes.

Red, Yellow & Orange Vegetables


Rich in antioxidant nutrients, lycopene, betacarotene and vitamin C, the red, yellow and orange coloured vegetables are a great support to immune function. Red capsicum contains almost 3 times more vitamin C than oranges and can be used in a wide variety of dishes! Other great nutrient rich vegetables include pumpkin, sweet potato, squash, beetroot, radishes, red onion, chillies and carrots. Vitamin C increases the number of circulating immunoglobulins, which are antibodies that attach to the pathogen to help the immune system identify and destroy it. Supplementation increases the activity of neutrophils, which act to identify and destroy both bacterial and viral pathogens and increase their vitamin C concentrations. Many of these vegetables can be juiced as well as cooked, so get colourful with your vegetables to support your immune health.

Tips to Boost Immunity
