Feed gut bacteria to ward off colds

WINTER is coming — the peak season for colds. So now is the time to bolster your immunity by nourishing the ‘good’ bacteria in your gut. A Mediterranean diet provides many of the vitamins and minerals your immune system needs, plus twice the fibre of a more processed Western diet. Think warming tomato and bean soup and grain-filled salads. You can also top up your good bacteria with probiotic supplements.
