If grandma liked working out, her pain may be your gain. It may seem unlikely, but recent research out of the Joslin Diabetes Center says it just might be the case. Laurie Goodyear, a professor of medicine at Harvard Medical School and section head for integrative physiology and metabolism at Joslin, has found that a grandmother’s exercise during pregnancy may make her grandchildren healthier metabolically, with less body fat, better insulin control and, in some, healthier bones. Goodyear and postdoctoral fellow Ana Alves-Wagner, who worked on the project in Goodyear’s lab, discussed the research—published recently in the journal Molecular Metabolism—with the Gazette.
