People talk about food in all sorts of different ways.
They say, "food is love," or "food is medicine," or "food is fuel," or "food brings us together." They say things like "nom nom nom," or "get in my belly," or "give me all the bacon and eggs you have." Hobbits love food so much that they eat 7 meals every day, including two breakfasts! Danny Meyer said that "love is hunger satisfied" and Virginia Wolfe wrote that "one cannot think well, love well, sleep well, if one has not dined well."
Obviously, food is important. We all need it. And there are so many sides of food that it would be silly to try to list them all.
