After a bumper cold and flu season last year, dietitians are urging Australians to boost their immune system this winter by tapping into nutritious comfort foods.
According to the Dietitians Association of Australia (DAA), focusing on whole foods, including those containing vitamin C, zinc and protein, can help immunity – a useful weapon in fighting off the germs that cause colds and flu.
Figures from the Department of Health show more than 14,000 cases of the flu were reported in Australia last year, a 36 per cent increase from the year before.[i] And the flu accounts for 13,500 hospitalisations and 3,000 deaths among Australians aged over 50 years.[ii]
While healthy eating may not ward off germs entirely, DAA spokesperson Simone Austin said making nutritious meals a priority in the colder months can reduce the likelihood and severity of colds.
She added that a nutritious diet is particularly important in vulnerable populations, such as the elderly, whose immune systems may already be compromised.
‘Foods high in vitamin C include capsicum, broccoli, kiwi fruit, strawberries and citrus fruit. Zinc is found in fish, seafood, beef and lamb, which also provide good-quality protein. Baked beans and pumpkin seeds also provide zinc. So there’s plenty of nutritious and tasty options. Now that winter has finally arrived, it’s time to enjoy tasty, warming foods that give you, and your immune system, a boost,’ said Ms Austin, an Accredited Practising Dietitian.
According to Ms Austin, a nutritious winter diet need not be expensive or complicated. She recommends nourishing winter meals, such as:
- Beef and bean stew
- Porridge topped with pumpkin seeds and chopped nuts
- Warming seafood soup with added dark leafy greens and slices of capsicum
- Grainytoast or a wholemeal muffin topped with baked beans
- Delicious fruit crumbles, using fresh or frozen berries.
For tailored nutrition advice on keeping healthy this winter, DAA recommends seeking the support of an Accredited Practising Dietitian.
