Dioxins transferred from mother to baby.

JAPAN -- A study of maternal transfer of dioxins by reports that levels of dioxins observed in fetuses and nursing infants reflect cumulative concentrations of dioxins in the mother's blood. These findings were noted in Chemosphere (2005, Volume. 61, Issue 9).

Researchers at Saiseikai Nara Hospital, Obihiro University of Agriculture and Veterinary Medicine, and Hokkaido Medicinal Plant Research Institute, found that when Chlorella pyrenoidosa supplements were added to the diets of 23 pregnant women, the amount of dioxins transferred was reduced by as much as 30 percent.

In investigating the methods of reducing maternal transfer, the teams produced a significant finding. The dioxin level of breast milk in the control group who supplemented their diets with C. pyrenoidosa decreased by approximately 30 percent, compared with those who did not take C. pyrenoidosa. This result suggests that these supplements may help to reduce the maternal transfer of dioxins, and the reasons may be attributed to the following:

* The cholorophyll and fiber contained in C. pyrenoidosa promotes the excretion of lipophilic contaminants such as dioxins.

* C. pyrenoidosa reduces lipid-containing quantities of breast milk, thereby decreasing dioxin concentrations

Another study conducted at the Fukuoka Institute of Health and Environmental Sciences in Japan suggests that chlorophyll may inhibit dioxin absorption from the gastrointestinal tract. In the study, published in Environmental Health Perspectives (2002;109: 289), seven groups consisting of 28 subjects were fed either a diet that included the dioxins PCDD and PCDF or a diet that included PCDD and PCDF plus chlorophyll According to the authors, the fecal excretion of the dioxins was "remarkably increased along with the increasing dietary chlorophyll." The findings suggested that chlorophyll could be effective in preventing dioxin absorption via foods.
