How
Yogurt Protects Us From Environmental Poisoning
Yogurt containing probiotic bacteria successfully protected
children and pregnant women against poisoning from heavy metal exposure,
according to a new study.
Working with funding from the Bill and Melinda Gates Foundation,
Canadian and Tanzanian researchers created and distributed a special yogurt
containing Lactobacillus rhamnosus bacteria and observed the outcomes against a
control group.
A research team from the Canadian Centre for Human Microbiome and
Probiotics, led by Dr. Gregor Reid, studied how microbes could protect against
environmental health damage in poor parts of the world.
Their lab research indicated that L. rhamnosus had a great affinity for binding toxic heavy metals. Working with this knowledge, the team hypothesized that regularly consuming this probiotic strain could prevent metals from being absorbed from the diet.
Working with the Western Heads East organization, Dr. Reid had
already established a network of community kitchens in Mwanza, Tanzania to
produce a probiotic yogurt for the local population. Mwanza is located on the
shores of Lake Victoria, which is known to be polluted with pesticides and toxic
metals including mercury.
The team utilized this network to produce and distribute a new
type of yogurt containing L. rhamnosus. The special yogurt was distributed to a
group of pregnant women and a group of children. The researchers measured the
baseline and post-yogurt levels of toxic metals.
The team found a significant protective effect of the probiotic
against mercury and arsenic in the pregnant women. This is important as
"reduction in these compounds in the mothers could presumably decrease
negative developmental effects in their fetus and newborns," according to
Dr. Reid.
While the results obtained in the children studied showed benefits
and lower toxin levels, the sample size and duration of treatment did not allow
statistical significance.
