What does food really mean for human beings? Does it simply provide the body with the “fuel” needed for life, like petrol in a car? We don't need to be researchers to recognize that this statement is somehow incomplete. We only need to be curious enough to observe that what we require for thinking, creating, feeling, or doing is not proportional to the amount of food we eat – a full belly is more often accompanied by feeling fatigued than by thinking innovative thoughts!
