Preheat oven to 350 degrees. Mix together all flour, salt, baking powder, baking soda and cinnamon and set aside. Combine shredded carrots and sugar in a mixing bowl and mix to combine. Add yogurt and eggs and mix until well incorporated. Slowly add dry ingredients and mix just until combined; stir in raisins. Fill lined or greased muffin tins about ¾ full and bake until a toothpick inserted in the center comes out clean, about 20 minutes.
