For those who are interested in the topic, i just finished reading this: https://www.goodreads.com/book/show/3109.The_Omnivore_s_Dile.... The author follows the ingredients of a meal he makes all the way back to the farms. He seems to romanticize certain notions of naturally grown foods and at other times, is given to polemic against the agriculturally industrial complex (quite justifiably at times). The book itself was a lesson in the history of agriculture, nutrition, politics, policy, cooking, animal husbandry and the organic food industry. There is a part of the book where he talks about the huge industrial setup behind organic food and tries to distinguish it from the vicissitudes of the small scale farmers life. He even turns into a hunter gatherer for a little to experience life as it was before agriculture. It was a totally fascinating read and i recommend it.
