from peta.org August 4, 1999 :

Grace Slick, Flower Power's original poster girl, has decided to celebrate Woodstock's 30th by promoting vegetarianism in a new advertisement from PETA.

Slick is a longtime PETA member. Last year, she donated a percentage of royalties from her classic song "White Rabbit" to PETA's campaign against Procter & Gamble's use of rabbits and other animals in product testing.

from USA Today, 2001:

Grace Slick rocks the world of meat - As lead singer for Jefferson Starship, Grace Slick survived on a diet of rock and roll excess. But these days she's down-to-earth, food-wise: She's a vegan.

"I'm in good health and people want to know what I do to be this way. Vegetarian is a slippery word," says Slick, who also sang for Starship's earlier incarnation, Jefferson Airplane. "I don't eat cheese, I don't eat duck — the point is I'm vegan."

from quotesandpoem.com (no dates or sources given):

It takes a little work to be a vegan, but now it's really possible to have tasty stuff and it's better for you. I say the best test is go as far as you can and see how you feel. Personally, I feel great.

You can't make people change, but the organizers of WorldFest hope that people consider being vegetarian for both moral and health reasons.

I am not strict vegan, because I'm a hedonist pig. If I see a big chocolate cake that is made with eggs, I'll have it.

I take some vitamins, but I'm careful because they can be bad for the liver. I fall down all the time because I'm such a klutz but I have never broken a bone and I don't eat milk or cheese ever. I like tofu cheese and soymilk in my coffee and cereal.

The main point for me is moral; animals are sentient beings. I know for some this is a hard argument to accept, but we're not built to eat a lot of meat.
