The immune system is the body’s defence against infections. When it’s working well, the immune system can help protect against illnesses and infections.

There are several key factors that help keep your immune system healthy and strong. Some of these factors include adequate rest, regular exercise, good hygiene, decreased stress, and a healthy diet.


Glucerna is a scientifically formulated, oral nutrition supplement, for adults with diabetes or impaired glucose tolerance4. Backed by 30 years of scientific evidence from more than 50 clinical studies with over 4,000 individuals.
Glucerna contains slow-release (low glycaemic) carbohydrates making it a great snack option for people trying to manage their blood glucose levels*4,6.  
In addition to this unique slow-release carbohydrate system, Glucerna contains other important nutrients, including:4 
  • A healthy fat blend that includes monounsaturated fatty acids (MUFA) and omega-3 fatty acids – for supporting blood vessel health and circulation in people with type 2 diabetes.7
  • Prebiotic dietary fibre – to support gut health.8,9 
  • 28 essential vitamins and minerals including antioxidants (Vitamins A, C and E), zinc and vitamin D that play an important role in immune health1,3.

*Formulated for people with prediabetes and diabetes, as part of a diabetes management plan including diet and exercise.



Poor nutritional status is associated with decreased immune health2. Including key nutrients as part of a well-balanced diet can improve your nutrition, and may help support and maintain your immune health.

PROTEIN helps build antibodies and immune cells and plays an important role in healing and recovery1,3. Sources: Eggs, milk, yoghurt, fish, lean meats, chicken, beans, soy products, and nuts and seeds. 

VITAMIN A keeps the skin, tissues in the mouth, stomach, and intestines, and the respiratory system healthy, and it helps regulate the immune system and fight infections1. Sources: Colourful foods like carrots, sweet potatoes, broccoli, spinach, pumpkin, squash, and rockmelon. 

VITAMIN D a fat-soluble vitamin that activates and regulates immune cells3. Sources: Fortified foods (milk, cereal, orange juice), fatty fish (salmon, mackerel, tuna), and sunshine. 

VITAMIN C helps build healthy skin, which is a barrier to microorganisms, and helps protect cells from damage due to its role as an antioxidant (a substance that helps protect cells)1,3. Sources: Citrus fruits (oranges, grapefruits, tangerines), strawberries, papaya, capsicum, and Brussels sprouts. 

VITAMIN E protects immune cells from damage due to its role as an antioxidant1,3. Sources: Almonds, sunflower seeds, peanut butter, vegetable oil, spinach, and broccoli. 

ZINC supports creation of new immune cells, which contributes to the body’s ability to heal from wounds1,3. Sources: Lean meats, chicken, turkey, crab, oysters, milk, whole grains, seeds.



Looking after your immune system

When you are unwell, your body will increase the production of stress hormones, which can raise your blood glucose levels.10 Some studies have also shown that spikes in your blood glucose levels can impact your immune system.11

There are a few tips that you can take on board, to help with your diabetes management plan. These include:10

  • Testing your blood glucose levels regularly to make sure that you remain within your target range
  • Eating foods that you can tolerate; this may include having small low-fat snacks regularly and consuming nutritious foods with the vitamins and minerals you need
  • Drinking lots of water to prevent dehydration
  • Seeking medical advice if you have symptoms such as breathlessness, nausea and vomiting, and abdominal pain.


Talk to your doctor about what you can do for your diabetes when you are unwell.
