Many Seventh-day Adventists traditionally have avoided baking powder and baking soda, preferring yeast-raised baked goods, based on what Ellen White wrote. However, below is a really good explanation of why she wrote what she did and how this applies to what we know today. The short story is:

  1. When cooking green vegetables, do not use baking soda to retain the green color because it destroys nutrients.
  2. When using baking soda, use enough acidic ingredient to match the alkaline content of the soda.
  3. To avoid using cornstarch, make your own baking powder with baking soda and cream of tartar.
