I grew up SDA. We ate eggs. Meat (beef, chicken, fish with scale and fins) was not forbidden but it was looked down upon. Potlucks were the worst since i was (am) a picky eater. No meat in sight. Mostly grey lumps in white gravy-ish sauce. I would survive on shells and cheese, mashed potatoes, and fruit salad.

It's possible we were just bad SDAs though. I've met some hardcore SDAs. I imagine how I felt about them was how "regular" Christians felt about me.

Sorry, this is way more information than you asked for...

They do. These days generally the main prohibition is pig derived products, but plenty of SDAs still choose to be vegetarian. I'm not an SDA, but my daughter is.
