toxic chemicals, and dietary alterations. Despite the striking findings of
some of the presentations, such as that by Hart and colleagues that DNA
repair efficiency and fidelity are markedly enhanced in caloric restricted
diets, the implications of these findings for human populations remains to
be further investigated and established. Nonetheless, this publication of the
BELLE program will provide the first of what is hoped to be a series of
carefully coordinated and focused reports that will clarify the biological
effects of low level exposures to chemical agents and radiation on biological
systems and human populations.
