People over age 60 have about 1 000-fold less "friendly" bacteria and more disease-causing bacteria in their guts compared with younger adults, scientists said at a briefing in London, BBC News reported.

"The (scientific) literature has reported about 80 human studies with positive results against bowel conditions like traveller's diarrhoea, irritable bowel syndrome and antibiotic-associated diarrhoea," said Glenn Gibson, professor of food microbiology at Reading University.

He said that while probiotic products are useful for healthy adults - for example, helping to fight bacteria that cause food poisoning - they are even more beneficial for older people, the BBC reported.

However, Gibson and his colleagues said consumers need to carefully check products to determine whether they contain the correct strain of live bacteria - such as bifidobacteria or lactobacilli - and that there are at least 10 million bacterium in the product. – (HealthDayNews)
