The immune system is the body’s defence against sickness. A healthy immune system protects the body from illnesses and infections. Factors that keep the immune system in top shape are adequate rest, regular exercise, good hygiene, decreased stress, and a healthy diet.1

Essential nutrients that build a healthy and strong immune system2

Insufficient nutrition is associated with decreased immune health. A well-balanced diet that include these key nutrients may help support and maintain a strong immune system.1

 Protein: An essential macronutrient needed for the creation of antibodies and immune system cells. Also plays an important role in healing and recovery. Sources: Eggs, milk, yoghurt, fish, lean meats, chicken, beans, soy products, and nuts and seeds. 1,2

 Vitamin A: Helps regulate the immune system and protect the body by keeping skin and tissues in the mouth, stomach, intestines, and respiratory system healthy. Sources: Colourful foods like carrots, sweet potatoes, broccoli, spinach, pumpkin, squash, and rockmelon. 1,2

Zinc: Needed for cellular reproduction, which is important in the synthesis of new immune system cells. This means zinc also contributes to the body’s ability to heal wounds. Sources: Lean meats, chicken, turkey, crab, oysters, milk, whole grains, seeds.1,2

Vitamin D: A fat-soluble vitamin that helps activate and regulate immune system cell function.  Sources: Fortified foods (milk, cereal, orange juice), fatty fish (salmon, mackerel, tuna), and sunshine. 1,2

Vitamin C: An antioxidant that helps the body build healthy skin and tissue to resist entry of bacteria and other germs. Sources: Citrus fruits (oranges, grapefruits, tangerines), strawberries, papaya, capsicum, and Brussels sprouts.1,2
