What would happen if we begin to consider food is less a thing and more a relationship? In nature, things have always been like this: eating meant in fact interacting whit species in the systems that we call food chains or tropic networks, which include everything up to the soils. Species co-evolved with the other species that eat them and very often, among them develops a relationship of interdependence: I’ll feed you, if you spread my genes.

Following an evolutionary process of mutual adaptation, the apple or the pumpkin turns into a nutritious and delicious food product for certain animals. Over time and through processes of trial and failure, the plant becomes tastier (and often more visible) to answer the needs and desires of the animal, and so that the animal can develop various digestive tools (eg, enzymes) needed to exploit the plant as good as possible.

Thus, at first, the cow milk was not a nutritious product for people: in fact, it even harms them that until the people who lived around cows developed in adulthood the ability to digest milk. The gene responsible for producing lactase, the enzyme that make the digestion of milk possible, was disabled by humans shortly after medical ablation, but now five thousand years, people have suffered from a mutation where the gene which remains active throughout life, the mutation that quickly spread through a population of pastors in north-central Europe. Why? Because people which suffered this mutation have access to a new extreme nutritious food source and therefore they could multiply more easily than those who had not undergone the mutation that we are talking about. This adaptation was good for those who consume milk but also for cows that have multiplied and expanded their habitat (and have improved their health status) all because of this new symbiotic relationships.

Among other things, health status is determined by the type of relationships within a food chain extreme varied relation in the human case which is an omnivorous. So, when a link from the food chain health is affected, this can be passed on to all other living creatures that make up that food chain. If the soil is sick or suffering from certain deficiencies so will be the gras growing on it and the cows grazing grass and the people who drink their milk. This is what Weston Price and Sir Howard was thinking when they were trying to establish a connection between these apparent distant spheres: soil and human health. We can not separate our own health from the entire health chain.
