Best Immunity Boosters For Kids

The soundtrack of winter in our household isn’t the romantic pattering of rain on the roof - it’s the constant sniffles and throaty coughs from little ones, as their immune systems fight off the latest day care lurgy😷

Although we can’t prevent kids from picking up snotty nosed germs (they literally put EVERYTHING in their mouths at the moment!), we can help support them nutritionally as they get through the winter sniffles. 

The immune system is a complicated and multifaceted battleground and although there is no such thing as a ‘quick fix’ when it comes to keeping well, the right nutrition can lay solid foundations to help strengthen and support the body and give it the best chance to overcome any seasonal nasties. 

NUTRIENTS FOR THE IMMUNE SYSTEM

There are some key nutrients that help to create the support system that our immunity relies on.

Vitamin C – Also known as ascorbic acid, Vitamin C is an essential nutrient in our diet. It has many biochemical and molecular functions including energy release from fatty acids, metabolising cholesterol and maintaining our connective tissue. For our immune system Vitamin C acts as an antioxidant (helps fight free radicals) and it can stimulate the production of interferons, which are the proteins that protect our cells against viral attack. The most concentrated source of Vitamin C are blackcurrents, capsicums, chillies, oranges and strawberries. 

Vitamin A – Plays an important role in immunity through its modulating effects. It helps to maintain the function of our white blood cells such as neutrophils, macrophages and natural killer cells (which fight foreign invaders in our body). Vitamin A also helps keep our mucous membranes healthy, which are the protective barriers that guard against pathogens. You can find high levels of Vitamin A in liver and fish oils, egg yolks and whole milk. Dark leafy greens, yellow/orange vegetables such as carrots and sweet potatoes also have an abundance of vitamin A. 

Allicin – Garlic has been used as a food and as a medicine for over 3500 years. Legend has it that garlic was used in Ancient Egypt to increase resistance to infection. Modern science has since discovered that allicin is the constituent responsible for many of garlic’s protective qualities. Research shows that allicin has a strong antioxidant activity, anti-inflammatory actions and antimicrobial properties that protect against various pathogens. The allicin works when the garlic is crushed or chewed and it becomes activated when alliin is exposed to another component, an enzyme called alliinase. So whenever you are added garlic to support immunity, remember to crush it up before adding it into your meal to unlock it’s protective powers. 

Ginger – Ginger is another food that has been used as medicine since ancient times. Ginger has been shown to be anti-inflammatory, antimicrobial, antiviral and it also has strong antioxidant activity. Ginger can have a strong flavour so add it gradually to recipes for kids as they might find it a bit too warming initially. 

Curcumin – Turmeric rhizome can attribute it’s immune stimulating properties to a constituent called curcumin. There has been lots of research that proved curcumin has anti-inflammatory, antioxidant, immunomodulatory and antimicrobial properties which can all contribute to the symptomatic relief of winter cold and flu. Like ginger, turmeric can be an acquired taste for little ones, so best to build them up slowly if it is a new flavour. 

Zinc – An essential trace element that is essential to all living cells. Zinc belongs to the class of type 2 nutrients that are considered the building blocks of our body. As well as being a cofactor in many biochemical reactions, zinc is also involved in many aspects of immunological function. It is essential for the development and function of cells, especially our white blood cells and it helps build our acquired immunity and is a key anti-inflammatory nutrient. You can find zinc in meat, liver, eggs and seafood as well as nuts, legumes, whole grains and seeds. Miso, tofu, mushrooms and green beans are also high in zinc.
