But Seventh-Day Adventists? Aren't they just Saturday-going Protestants with a health-nut twist?

I wish I knew what the falling out is between 7DA and the SBC. 7DA has distinctive Sabbath doctrines that the SBC emphatically disagrees with, and there are the 7DA food and drug taboos that SBC thinks are nonsense, but their "fundamental" (pun intended) view of Christ and salvation is, as far as I can understand, virtually equivalent. If 7DA doctrine ascribes salvational significance to their Sabbath and health practices, that would be different... but I've never heard that.

The primary doctrinal differences between the SBC and the SDA church are [1] the SDA's acknowledgement of Ellen White's writings as inspired and [2] the SDA doctrine of investigative judgment which make a person's works the basis for final eternal judgment. All other issues (Sabbath and dietary restrictions) are secondary to these issues.
