Now is the optimal time to take action on your winter immune prevention program instead of allowing a winter infection to put your life on hold. An effective winter immunity and prevention program offers you support to help protect you from the dreaded ‘winter lurgy’, minimising the impact that illness can have on your life.
The common cold is easily transmitted and responsible for most absences from work and school annually. Our aim in prevention is not merely to strengthen the immune system but to keep the body in a state of balance so that illness does not occur, or so that when it does, the illness is only mild because there is only a small imbalance to correct. This works best when we strengthen the whole person and the whole family alike, while simultaneously strengthening the immune system.
Good Bugs, good gut, good immune system
When it comes to boosting immunity to prevent cold and flu, surprisingly gut health is a key area of focus. The digestive tract is in close contact with the largest part of the immune system in the body – over 70%. It is also home to a plethora of bacteria known as our gut microbiota. Certain ‘good’ bacteria, naturally found living in a balanced relationship in the gut, have supportive benefits – stimulating the activity of the immune system and boosting our immune defences. It is essential to support gut function to help reduce your risk of developing a winter illness.
We can support these good bacteria by eating certain foods that cause them to increase in number. Food is a powerful tool for boosting gut health and can be used safely for children, the elderly and anyone with poor immunity. Here is what to include:
Specific strains of probiotics are demonstrated to reduce the frequency, severity and duration of infection such as colds and influenza and can be prescribed by your naturopath where appropriate.
Supporting immunity is one of vitamin D’s numerous roles, specifically in the defence against infections as it improves the antimicrobial properties of immune cells on exposure to microbes.
Research supports the use of vitamin D supplementation to reduce infections. One study showed that, over a three year period, women taking vitamin D were three times less likely to experience cold and flu symptoms compared to those who did not. The study highlighted, that a low dose of D3 drastically reduced the seasonality of reported colds and flu, whilst a moderate dose virtually eradicated all reports of upper respiratory tract infections.¹
Adequate sun exposure is vital for maintaining vitamin D levels. Back this up with dietary sources including eggs and fatty fish, like tuna, mackerel, and salmon. Getting sun can be hard depending on your location and diet isn’t enough alone so vitamin D3 supplementation needs to form part of your winter immune prevention program to reduce the incidence of cold and flu.
Zinc has immune boosting benefits as it plays an integral role in the maintenance and functioning of the immune system. The most potent food sources include: oysters, red meat, chicken, eggs, nuts, sesame & pumpkin seeds, spinach, mushrooms. Higher doses of zinc in combination with vitamin C in the form of a supplement can be used to support the immune system and help reduce the incidence of infections.
Add all ingredients to a saucepan and bring to the boil for at least 1 minute.
Strain the tea into your favourite cup and drink warm throughout the day.
