Dr. Terry Mason, COO of Cook County Department of Public Health (and a vegan!), will share with us all the "whys' and "hows" of healthy eating, including the cause and cure of much of our heart disease, strokes and cancers. He is the host of "A Doctor in the House," every Sunday morning at 10:00 a.m. on WVON, 1690 A.M. and one of Chicago's most exciting speakers.
