Probiotic yoghurts DO work

After wolfing down a pizza you may want to finish with a probiotic yoghurt, after researchers found they help the body to break down carbohydrates.
Scientists from Washington University School of Medicine wanted to look at what impact, if any, live bacteria in popular yoghurts have on digestion.  They performed studies on mice as well as identical female twins using a yoghurt that had five strains of live bacteria.
The team found eating the yoghurt twice a day for seven weeks did not alter the mix of microbes in the intestines of the women or the mice. However, when they took a closer look at the mice they found there were significant changes in some of the bacterial enzymes involved in metabolising carbohydrates.
Many of the key changes noted in the highly controlled laboratory environment were also found in the seven pairs of twins.
