Applesauce makes moist cakes

The other day, I heard on one of the news morning shows to substitute applesauce for oil when making cakes, breads, etc to make them healthier. I just baked a cake (from a box mix) substituting the oil with applesauce (a 1:1 substitution...so if it calls for 1/2 cup oil, use 1/2 cup unsweetened applesauce). Not only is it a little better for you but it will make the moistest cake!!
