In the scene with Kitty, (Calista Flockhart), and her mother Nora, (Sally Field), in the doctors office, Nora offers some gum and then some calcium chews. You can see Kitty giggle a little bit before saying "no thank you, I'm fine." This is an inside reference to actress Sally Field's real diagnosis of Osteoporosis (bone loss/bone thinning) right before she turned 60. Adding intake of calcium can help slow down/prevent loss. She went on to star in the commercial for the medication Boniva.
