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.1

There are several key factors that help keep your immune system healthy and strong. The best thing to do is make healthy lifestyle choices, such as:2,3

• Getting enough sleep

• Eating a wide range of healthy foods like fruits and vegetables

• Drinking enough water

• Maintaining good hygiene

• Practice stress-reducing activities such as meditation, mindfulness, or connecting with family and friends

Poor nutritional status is associated with decreased immune health.10 Including key nutrients as part of a well-balanced diet can improve your nutrition, and may help support and maintain your immune health.

PROTEIN is important for the structure and function of your cells. Protein is important for your brain, your immune system and for gut mucosal function. Great sources of protein include eggs, milk, fish, lean meats, chicken, vegetables, soy products, nuts and seeds.11

VITAMIN A maintains normal reproduction, vision and immune function to fight infections.11 Vitamin A sources include leafy green vegetables, carrots, sweet potatoes, pumpkin, as well as soy products, nuts and seeds.12

VITAMIN D is a vital for maintaining the immune system and helps with the absorption of calcium. Some food sources of Vitamin D include fortified foods (milk,  yoghurts and cheese), fatty fish (salmon, herring and mackerel) and eggs.11 

VITAMIN C supports skeletal and vascular system, and can help the immune system.11,13 Food sources of vitamin C include citrus fruits, strawberries, broccoli and sprouts.11 

VITAMIN E protects immune cells due to its role as an antioxidant.13 Sources of vitamin E include vegetables, the fats of meat, poultry and fish.11 

ZINC supports the structure of protein in your cells – this means it helps support the function of your immune system. Zinc is found in a wide range of foods including meats, fish and poultry, as well as cereals and dairy foods.11

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.
