KIDS' NUTRITION AND IMMUNITY: HOW TO SUPPORT YOUR KIDS' IMMUNE SYSTEM NATURALLY
What is the immune system?
Our immune system is our protection from viruses, bacteria and other pathogens. It is our coat or armor as well as our armies that protect us. Our immune system is a complex and multi layered system that operates to keep us protected and well.
There are three layers of protection in our immune system, each responding to different threats.1 The first part of the system is the barrier system, which is both physical and biochemical and works to trap invading organisms or substances. This includes the skin, sweat, saliva and tears. The second and third parts of the immune system are the actual immune cells and antibodies that work to protect us internally. Each of these parts work together to form our overall immune system.
The defense strategy of the immune system can be divided into two categories. The first is called ‘innate immunity’, and it refers to the immediate response of the immune system to foreign pathogens. The other is called ‘adaptive immunity’, and it refers to parts of the immune system which use the memory of previous pathogen threats to enhance its immune response.
How is nutrition and immunity linked?
There are tight links between nutrition and immunity.2 Malnutrition is considered one of the leading causes of immunodeficiency (weakened immunity) in the world.3 While within first world countries we have the issue not of malnutrition due to lack of food, but issues of nutritional deficiency from the inadequate nutritional composition of over processed and discretionary foods and drinks.4
What weakens the immune system?
Certain lifestyle factors can weaken the immune system. Poor sleep pattens, exposure to pollution/toxic chemicals and a lack of clean air or sunshine can create oxidative stress on the body that in turn can modify or suppress the immune system1.
For infants, children and teens, diet can play a major role in either supporting or hindering the immune system. The role that the diet plays on a child’s immunity is twofold. Firstly, a poorly composed diet will lead to nutritional deficits that may impact proper immune function through suppression or dysfunction of the immune response.5 Secondly, a diet of highly processed, refined, discretionary foods may lead to oxidative stress and inflammation which can further burden the immune system.
What are the health consequences of having a weak immune system?
It has been reported that on average, the American child can get up to 12 colds a year.6 This is not only an issue for the child but for the caretaker and family members as well. Time off school or work, lack of exercise, or subsequent family members becoming ill can all create a cycle of illness and stress. A child who is unwell is likely to also have a diminished appetite, which in turn leads to decreased nutritional intake and therefore poorer nutritional status. This potentially leads to greater nutritional deficiencies, thus resulting in compromised immune function and lower immunity7.
What helps to strengthen the immune system?
There is a strong correlation between individuals who have robust immune systems and the qualities and interactions of the following four factors: genetics, environment, lifestyle, nutrition8. Whilst we have limited control over genetics and environment, we do have a good ability to influence nutritional status and lifestyle factors, especially for children and teens.
What foods and nutrients help to boost the immune system?
When we think of immune boosting nutrients and foods, most of us will immediately think of Vitamin C, garlic and cod liver oil. However, if you have ever tried to give a child, particularly a picky eater, garlic or cod liver oil you’ll know that getting beneficial nutrients and foods into their diet isn’t always easy.
From a nutrition perspective, some of the vitamins, minerals, and functional foods that are required for a strong immune system include vitamin A1,5,8, vitamin C1,5,8, vitamin D1,5,7,8, zinc1,5,7,8 and probiotics7,8. Each of these micronutrients work in different ways to help strengthen the immune system. Some help support the physical barriers of defense, while other nutrients strengthen and support the immune cells and antibodies to perform their roles.
