How can I prepare for a healthy pregnancy and a healthy baby?

I’m 21 years old and east Indian. My husband is 49 and Caucasian. Are there more risks with having a baby if it is interracial? Does the father’s age the baby’s health>?
Also how can I prepare for pregnancy? I want to do everything possible to help have a healthy child and a healthy pregnancy. Any tips or advice? We plan to start trying maybe in January. Thanks! I appreciate it so much
