Yellowlees came from a Scottish settlement that earned its living from the land. Yellowlees soon realised that this self-same land was perhaps the source of health in the community. As modern foods became increasingly available, Yellowlees noticed a decline in health.
This is masked by a delusion noted by Yellowlees,
- "...that if only everyone had unfettered access to the best available medical services, people would get healthier."
- "Where do we go for prevention?"
- "The simplicity of the idea that so much disease could be caused my modern malnutritn may be difficult to accept, and the though of nature's laws quite baffling. Man bestrides a natural world. He dominates all living things but he is utterly dependent on them. He is supported by the plants, the trees, and the animals. The whole system rests on the soil which is itself vibrant with life. If any part of the supporting system is taken away, man will begin to fall off his perch.
The laws of nature applied to nutrition simply require that the flow of nutrients from the soil through the plants and the animals to man should be as little meddled with as possible. The flow is dependent on an infinite number of biological relationships which can neither be counted not measured."
- "At a time of ever-increasing centralisation of government control there is a grave danger of such beliefs being enshrined as dogma and incorporated in programmes for prevention, of unproven value and of possible danger...This danger is well illustrated by the dogma f animal fat and the branding of animal fat as the villain of human nutrition."
- "We are moving gradually into a world of designed consumer foods. Natural farm produce such as milk, potatoes, and grains are no longer just complete foods to be eaten as part of a meal. They have become ever-expanding sources of raw material to be utilised as building blocks for new and more diverse synthetic foods."
