Eating is the first action we perform after being born (well, after letting out a loud cry). To a human being, the act of eating is one of the most primal. We develop our most intimate relationship with food.
Interaction over food is the single most important feature of socializing. We eat together at times of celebration or mourning; we solve our problems over dinn, entertain guests over tea and cake, and conduct business over a lunch table. Whole cultures define themselves through food (when people move around the world their cultural cuisine is the last thing to stay even when other cultural traditions are abandoned).
However, in a culture of over achievement and high stress, we turn too much to food for solace and we do it to the detriment of our health. We now eat on the go, while driving, working on a computer or talking on the phone. The tradition of formal mealtimes is becoming a thing of the past: we eat whatever we want whenever we want. Many have completely lost touch with what eating is about and how to eat properly.
