To keep from getting osteoporosis, Dr. Oz says there are a few crucial things you can do. First, lifting weights will keep your bones strong. Next, avoid drinking too much alcohol and smoking, especially when you're young. The third is making sure you get enough vitamin D, which Dr. Oz says is his favorite vitamin. While the sun provides a potential bonanza of easy vitamin D, people who live in northern states—anywhere north of Atlanta or Los Angeles—tend to not get enough.
This nationwide deficiency could be a cause of many serious health problems, including autoimmune disease, Dr. Oz says. "We think it might be responsible for a lot of cancers in this country.
