She's not a vegan.
"these days, the best descriptor i can give myself is to say that i am a nutritarian. the nutritarian diet is a way of eating that bases food choices on taking in the maximum micronutrients per calorie"

She is actually a vegetarian since she calls herself "80%" vegan. Hopefully she gets to 100%?

I knew that a long time ago cause she looks like a person who loves animals

I'm enjoying on her music since I was a child. :) Being a vegetarian/ vegan like her (and also us) can save animals.

Alanis Morissette is

In 2010 Alanis Morrisette married the father of her baby, "Souleye." I recognized his face from a photo online. "Souleye" performed at a club nearby my house with some local bands whose members we know. He rapped but I couldn't understand a word he said. Anyways, such a small world. How incredible that a young kid from the block gets hooked up and marries Alanis Morrisette!

cool, i like her music!

I'm curious as to how many years as she been a vegetarian for. Anybody knows?

I've heard Alanis Morrisette songs played all the time in the early 2000s. I didn't really get into the music, but I liked her anyway. But, the juice is that I saw her once. I was taking care of a house that was up for sale, and Alanis and her then boyfriend drove up to the house to have a look. I couldn't believe it when she walked up and introduced herself to me! She was quite short and very friendly. She didn't buy that house. That's all.
