Preheat the oven to 375 degrees F. Grease the baking sheets. Combine the flour, oats, sugar, salt, baking powder, baking soda, and cinnamon in a large bowl until mixed. Combine the egg whites, corn syrup, and vanilla in another bowl and beat until well mixed. Fold the egg white mixture into the dry mixture. Stir in the raisins. Drop the batter by rounded teaspoonfuls onto the baking sheets. Place in the oven and bake at 375 degrees F for 10 minutes or until set. Do not over bake. Remove the cookies from the baking sheet and let cool on a wire rack. Store the cookies in an airtight container.
