Heard of the "Big Three"?

I don't and didn't know about Blossom but I found this interesting bit about its star:

I remember reading a few years ago - you know, the way rumors spread between Jews - that you were active at UCLA Hillel, and that you'd started getting more observant. Um, are you?

My mother was raised Orthodox, and my grandparents are immigrants from Eastern Europe. I was raised in a Reform household, but with a lot of remnants of Orthodoxy. We lit candles. We had two sets of dishes, but my mom never told me why. I thought it was breakfast dishes and dinner dishes. There was no emphasis on halacha and learning. Totally not to disparage my parents; it just wasn't their thing.

When I went to college, I didn't have a lot of friends. Blossom had ended two years before. I'd always gone away to Jewish camps for the summer, and so I kind of ended up at Hillel and I started learning with the rabbi, and it kind of took off from there.

I'm hesitant to label myself or call myself Orthodox because people will be like, "Celebrity Mayim Bialik says she does X, but I saw her doing Y" - I guess, to be safe, I would say I'm Conservative, but in reality, I'd say Conservadox. But my husband and I have definitely increased our observance over the years, and we're always trying to grow.

We kinda do the Big Three [Shabbos, keeping kosher, and family purity], but it's hard. I mean, it's hard for everyone to classify themselves, but it's a whole new level of hard when people are watching you. Like, I pretty much eat a vegan diet, but I eat eggs if they're in things. What I say is, I eat a mostly vegan diet, and that's kind of how it is with Judaism. We keep Shabbos, we keep kosher, and I don't know if people want to hear about the Mikveh, but, um, yeah.

You can see her in 1989 at a Chabad Telethon here (at 2:20)- "Mayim says L'chayim".
