Immune system saviour: Live yoghurt
Probiotic drinks and yoghurts contain active cultures of 'good bacteria' that support the hard workers in your gut. These healthy bacteria keep your intestinal tract free of disease-causing germs, so it's worth giving them a helping hand. A study from the University of Vienna in Austria found that a daily seven-ounce dose of yoghurt was just as effective in boosting immunity as taking tablets. In an 80-day Swedish study of 181 factory employees, those who drank a daily supplement of Lactobacillus reuteri—a specific probiotic that appears to stimulate white blood cells—took 33% fewer sick days!
