A note on the mulit-cultural, mobile society. In days of old the people from a village or tribe would have all eaten the same foods, perhaps a whole trible would have not had milk ever, or a tribe that never ate fish. But with people from vastly different backgrounds interacting more and more, it sometimes becomes tricky to cater to all tastes. We have almost completley lost the tradition of ‘this is what I like to eat because its what we ate in my town’. Peoples diets are based on what their body does and doesn’t like, and then after that consideration, on a wide number of learnt experiences and beliefs. In all, a good thing. But try cooking a meal for a bunch of friends, one a vegan, one on a gluton-free diet, one who can’t have starch, and one who gets delierous if he had chilli.
