70% of the immune system is found in the digestive tract! This means the bacteria – both friendly and bad – in the gut can influence the immune system(1). When working properly, the immune system is designed to fight disease and keep bacteria and viruses at bay. Whilst exposure to bugs and germs in everyday lives can strengthen children’s immune system, if weakened at any time, our children become more venerable and susceptible to colds, flu and serious illnesses(2).
Top tops to boost your child’s immune system
Fruit and vegetables are a rich source of various immune boosting substances including fibre, and vitamins as well as phytochemicals including carotenoids and flavonoids. These substances are essential for the optimal functioning of the immune system(3).
Dietary fibre is the indigestible part of plant material and includes two main parts; soluble fibre and insoluble fibre. Soluble fibre absorbs water to form a thick gel substance whereas insoluble fibre cannot be digested and remains unchanged through the digestive system. Soluble fibre can feed the good bacteria in the gut which can enhance your child’s immune system. Foods high in soluble fibre include; beans, peas, oats, barley, apples and citrus fruits(4).
Vitamins are essential components of our diet and have been known to support the immune system. The table below highlights three vitamins that can help boost your childs immune system and what foods to find them in(5).
As bacteria can have an effect on immune functioning it is important that children have a diverse population of friendly bacteria in their gut! Taking a daily supplement of live cultures can help support their immune system.
