All human beings at one stage of their lives have to be able to digest the lactose in their mothers' milk. But for almost all mammals, as you get older the ability to synthesize the lactose enzyme diminishes until you get to a point where you simply can't digest milk.
Although pigs were originally domesticated in the Middle East, and they were raised and consumed for five to six thousand years before the writing of the prohibitions, they were adapted to ecological situations which were rather rare in the Middle East and which became rarer as time went on.
Another benefit that comes from this prohibition on the slaughter of cattle is that it puts a barrier between the farmer and his cattle when there are droughts or other agricultural crises. It is essential that farmers hold on to their plough animals and not give them up for slaughter.
But with the passage of time, my position has become generally accepted, in India at least, as being the best way to understand the prohibition on the slaughter of cattle and consumption of beef in India.
Cattle occupied an essential position in Indian agriculture as power animals, and a choice had to be made between raising cattle for plowing purposes and raising them for meat production; the Indian ecosystem and production system couldn't support both functions.
Eating is a very sensual aspect of our lives. It can also be a very puzzling one; for example, why for a Hindu is beef a tabooed item, whereas in Canada and the U.S.A. and most of the Western world is it considered to be a very honorific and delicious food?
Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.
For example, in southern India, there are more cows than there are male cattle, whereas in northern India there are more male cattle than there are cows. This is related to the different demands made by the regimen of planting wheat in the North versus the regimen of planting rice in the South.
For example, meat versus lettuce -or spinach. Second, on the ecological level, under particular circumstances or given certain kinds of production systems, what is the effect of utilizing one kind of resource and not utilizing another?
Good to Eat is another extension of a perspective on how to account for cultural differences and similarities on a global basis, an application of certain general principles for understanding human social life to a particular set of what appear to be unanswerable questions about food preferences.
Here you do have forests, where pigs could be raised by letting them root about in the forests for a good part of the year. Therefore, you have a different attitude toward them compared with what continues to exist in the Middle East.
