LACTO-WHO?

You’ll have seen the word “probiotics” on yoghurt packaging, which refers to the beneficial bacteria that are used to ferment milk to make yoghurt.

Your gut already has thousands of types of bacteria, which aid digestion. The good bacteria stave off disease-causing bacteria and those present in yoghurt and other fermented foods help to maintain this delicate balance. The bacteria used to make yoghurt are most commonly Streptococcus thermophilus and Lactobacillus bulgaricus. They feed off the lactose (sugar) in milk and release lactic acid, which gives yoghurt its characteristic tang.
