Much recent research has shown that healthly gut flora may be responsible for our future health. More people understand that repopulation of the gut with 'good bacteria' is desirable. The overuse of antibiotics has depleted the mircobiome in much of the western world's population, not forgetting our farm animals too so reintroduction of live bacteria from products like Acidophilus, Symprove, Yakult etc are a good thing but if this new research is accurate it could mean a drastic turnaround in our childrens health and weight issues if we could ensure a good bioflora in early years.
