Which foods can improve your gut bacteria? Well last night the BBC 2 show ‘Trust Me I’m A Doctor’ revealed to the country that Kefir was the most beneficial.

In an experiment, 30 volunteers were split into 3 groups. Each group were asked to try a different approach for 4 weeks that, it’s claimed, can boost gut bacteria for the better.

The first group tried an off-the-shelf probiotic drink, found in many supermarkets. These drinks contained 1-2 species of beneficial bacteria. The second group tried traditional Kefir, containing an array of bacteria and yeast. The third group were asked to eat a diet rich in prebiotic foods such as garlic, onions, artichokes and leeks.

After 4 weeks, the group that saw the biggest change was the Kefir drinking group. They saw a rise in a family of bacteria called Lactobacillales. These bacteria are good for our overall gut health and that they can help conditions such as traveller’s diarrhoea and lactose intolerance. So next time you want to get a probiotic boost, head for a bottle of Kefir.

If you want to find out more about gut health and the results of the experiment, head over to BBC iplayer and watch the show.
