Wang, M.D., Sc.D., an epidemiologist, nutritionist and a member of the medical school at Harvard Medical Faculty and Brigham and Ladies’s Hospital in Boston.
Wang and colleagues analyzed knowledge from the Nurses’ Well being Examine and the Well being Professionals Observe-Up Examine, two research together with greater than 100,000 adults who have been adopted for as much as 30 years.
