Plants eat sunshine by converting solar energy into plant food through the process of photosynthesis. Animals grow by eating plants that eat sunlight and by synthesizing vitamin D, which grows healthy bones, from the sun’s ultraviolet light. And at the top of the web, humans eat plants and animals or one or the other. When ya get down to it then, what we eat is sunshine; it’s just converted into different forms throughout the food chain. If we are what we eat, then fundamentally―we are sunshine. So you see, the sun, it shines on you and from within you.
