To Boost Immunity
A strong immune system is your best line of defence against colds and flu, and thankfully, you don’t have to invest in expensive vitamins or over-the-counter medications to increase your natural immunity.
Rather, the easiest and most effective way to boost your immune system is to ramp up your intake of healthy fruits and vegetables.
What should you eat?
Dietician Denise Griffiths, spokeswoman for the Dieticians Association of Australia, says antioxidant-rich, in-season fruit and vegetables are your first port of call.
“Eating a wide range of fruits and vegetables each day will give us the best mix of antioxidants in the right amounts,” she says.
Skipping breakfast is also a big no-no if you want to avoid the winter sniffles, and keeping up with regular exercise is beneficial, as it’s a known immune system booster.
“According to a U.K. study involving more than 180 people, eating breakfast [was found to] also help fight off colds and flu,” Griffiths confirms.
“Along with stress, the researchers found that missing breakfast was linked to susceptibility to illnesses such as the common cold.”

Oranges and mandarins are a great source of antioxidant-rich vitamin C, which increases the production of infection-fighting white blood cells and antibodies.
