The 75-year-old actress said she takes twice-daily yoga sessions and recently went through a week-long cleansing regime, avoiding all dairy products, red meat, wheat and coffee, reported Daily Express.
"For a woman, making peace with your body is a work in progress. I have spent time in therapy, written books that have helped me heal � as well as helped others. For me, healing meant understanding that good enough is good. We don't have to be perfect," she said.
"I started the year with a week-long cleanse � no coffee, dairy, red meat or wheat. Instead I had lots of juices, vegetables, chicken and fish, oats, beans and cleansing teas.
"I'm still basically eating that way now, and will probably never go back to coffee. I eat fish, especially salmon and tuna, three times a week. This is really good for older people," she said.
The actress recently released a yoga DVD.
