With flu season quickly approaching, one of Australia’s most trusted health and wellbeing experts says we should be focusing on improving our gut health to boost immunity this winter.
Dr Joanna McMillan, renowned nutrition scientist and Accredited Practising Dietitian, believes gut health isfar from a passing health fad with scientific research showing there is a proven link between our immune and gastrointestinal system.
“Close to 70 per cent of your immune system is actually housed in your gastrointestinal tract, so it’s important to keep it in good shape,” she said.
“Probiotics can be a valuable strategy for boosting immune function during winter as they have been shown to reduce the number and severity of respiratory infections.”
According to Dr Jo, one of the simplest ways to improve gut health is to increase the intake of probiotics – living bacteria present throughout the human intestinal tract.
Probiotics can be helpful to boost the balance of ‘good bacteria’ in the intestines, to maintain a healthy gut and boost our immune function.
“You can take them naturally by consuming traditional fermented foods and drinks, including kombucha. However for optimum results, it’s really important to choose a kombucha with a probiotic strain backed by science,” Dr Jo said.
Dr Joanna McMillan’s top five tips for boosting winter immunity
- Limit junk food and eat more fibre
Junk foods encourage the wrong types of bacteria to grow and become dominant in the gut. Instead, Dr Jo recommends eating a plant-rich diet with whole, minimally processed foods packed with fibre. Many fibres are also prebiotics, which fuel the growth of good bugs in your gut, resulting in a healthier immune system.
- Make sure you’re getting enough probiotics
Probiotics should be taken every day for maximum benefit, especially in winter. You can get your probiotic-fix from a daily supplement, or for a tastier and more refreshing alternative, try kombucha*. Just remember to always choose a kombucha that’s chilled, and contains a scientifically proven strain of bacteria.
- Get enough sleep
There’s a link between sleep and immunity, and it’s only just being recognised for its importance. If you’re sleeping poorly or not getting enough sleep, you’re more likely to snack on sugary foods throughout the day to boost your energy levels, and then skip exercise due to tiredness. Dr Jo says most adults need seven to nine hours a night.
- Limit alcohol
Alcohol can irritate your digestive system by causing inflammation, so if you’re experiencing problems with your gut, it’s best to avoid it. Even moderate drinking increases your risk of bowel and other cancers, so if you choose to enjoy alcohol, be sure you do so in moderation. The Australian guidelines recommend drinking no more than two standard drinks on any day for healthy men and women.
- Stay hydrated
Not drinking enough water can slow down your digestive system, resulting in harder stools that are more difficult to pass. According to Dr Jo, there’s an easy way to tell whether you’re drinking enough – your urine should remain a light straw colour, all day long.
** Kombucha is a sparkling, fermented tea with living probiotics (‘good’ bacteria), organic acids and vitamins, that’s taking Australia by storm.
