Currently on Earth, the main purpose of food is to give you energy so that you can sustain the physical body and all the Divine functionalities of it. You also still have very active taste buds; hence, you feel pleasure in eating certain foods. You will be going through a shift in how you consume food once your crystalline Light body starts to merge with the physical. The first thing that will change is that your taste buds will be very sensitive and selective, as well as your sense of scent. Your body will also start rejecting anything that carries really dense energies. Next, and this will be in what you perceive as a further future, you will not need to eat much food or any food at all because your source of energy will not come as much from the external world as it will from your internal Light body system.
