My uncle used to raise pigs. Whenever I went to visit, I always wanted to go and look at them. He always warned me to never get close because they may try to eat me.
Actually it’s because Superman comes from Krypton, a planet that revolved around a red star, where as Earth revolves around a yellow star, which gives off more energy. Superman’s body absorbs that energy and stores it like a battery, and it results in him having powers. I doubt that simple healthy eating would grant anyone the ability to be “more powerful than a locomotive”.
