It is now widely understood that 70% of our immune function is regulated in our gut and this is very much influenced by our gut microbiota.
Our gut health has a very definite link to our immune health.
To ensure your gut is working at its optimum, to then support your immune system, it is important to give your gut the right ingredients:
Tip #1 - Prebiotics
These are your sources of fibre from vegetables, fruits, grains, pulses, herbs and spices. Variety is the key here, so we should be aiming for 30 different sources of plant foods each week!
Tip #2 - Probiotics
These are the live organisms (or viable ones) in your fermented foods like Bennetts Kombucha, kimchi, kefir, sauerkraut, live yoghurts etc.
"Diet is important in immune function and we know that diet quality has an affect on the gut microbiome and we know that the microbiome and the immune system are absolutely linked" - Prof. Tim Spector

Tip #3 - Vitamin D**
Is an essential nutrient and it has been seen to help improve the diversity of microorganisms in the gut. **In addition it is recommended by Public Health England that all residents in the UK take Vit D supplementation daily (10 mcg or 400iu) between October and March.
