A new study published in the journal Aging suggests that eating 100 grams of plain probiotic yogurt every day, along with following a healthy diet and regular exercise, may help slow the body's biological ageing. Researchers found that participants who followed the 12-week lifestyle plan experienced a 2.2% reduction in the pace of ageing. However, scientists caution that the benefits appear to come from the combined effect of probiotics, healthy eating and physical activity, not yogurt alone.
