Food and your immune system

Food and your immune system

A healthy, balanced diet helps your immune system do its job properly — alongside enough sleep, regular exercise and managing stress.

If you're living with diabetes or heart disease, having a plan for your nutrition takes the pressure off — especially during busy weeks, illness, or times when getting to the shops is harder than usual. A pantry stocked with the right basics means a healthy meal is always within reach.

What you will learn in this fact sheet

This fact sheet is a practical guide to building a pantry that works for you.

  • How to take stock of what you already have and shop with a plan.
  • The shelf-stable staples our dietitians keep on hand.
  • Whether frozen, fresh or canned is the better choice.
  • What to leave on the shelf when a special looks tempting.

Make a plan

A little organisation goes a long way.

  • Do a stocktake. Check what's already in your pantry and look at the use-by dates before you shop.
  • Make a grocery list of longer-lasting, shelf-stable foods from the major food groups: grains and cereals, vegetables, fruit, dairy, and meat or protein alternatives.
  • Put the healthy food front and centre. Make healthier foods more visible in your pantry, and keep treat foods out of easy reach at the back of the cupboard.

A dietitian's shopping trolley

These are the staples our dietitians reach for.

Protein sources

  • canned fish
  • nried or canned legumes
  • nuts, seeds and nut butters
  • UHT and powdered milks.

Grains

  • rice
  • pasta
  • quinoa
  • rolled oats
  • wholegrain bread or wraps — freeze them to extend their shelf life.

Dietitian approved: enjoy oily fish such as salmon, mackerel or tuna two to three times a week to help support heart health and brain function.

Dietitian approved: grains and cereals can get a bad rap, but dietitians understand how important they are in everyday diets. They contain a wide range of vitamins and minerals, and they're high in dietary fibre — which helps stabilise blood glucose levels and keeps you feeling fuller for longer.

Frozen, fresh or canned — which is best?

There's a place for all three.

  • Frozen fruit and vegetables are just as nutritious as fresh, and occasionally more so.
  • Fresh vegetables that last longer include potatoes, onions, carrots, pumpkin and cabbage. Longer-lasting fresh fruits include apples and citrus.
  • Canned options can be less nutritious, but they're convenient, budget-friendly and keep for a long time. Where you can, choose canned products that are reduced-salt and reduced-sugar.

What to limit

A few things are worth being deliberate about when you're stocking up.

  • Be careful of supermarket 'specials'. Junk foods like chips, chocolate blocks, lollies and soft drinks are discounted more heavily than healthy foods in Australian supermarkets, so a special isn't always a saving.
  • Skip high-sugar breakfast cereals wherever possible if you're living with diabetes or heart disease.
  • Use our shopping guide. The dietitians at the Baker Institute have put together a Supermarket shopping guide with healthier product swaps.
