John confesses that he finds it difficult to accept that there is such a thing as ‘disease’. 

“I can see that the body is made of cells only – and if this be the case then it is only cells that can go wrong. And they can become less functional by poor feeding (nutrition) or poisoning (toxicity).

The latter can be a huge area in so much as the ‘poison’ state may be caused in many ways, including the water we drink, the air we breathe, the food we eat, chemical medicaments – and most importantly ‘our thoughts’. Thoughts can be really damaging to the body – You may have lost someone dear to you and are in deep grief; You may be worried about others or about your future; You may be in a state of real fear – and so on.”

“All of the above mental states may lead to the body being in an acidic condition – a state of ‘metabolic acidosis’, which is not a beneficial area for healthy existence.” 

At this point John refers to Professor J E R McDonagh F.R.C.S (1881 -1965 ) and his Unitary Theory of Disease. The essence of this theory covered in depth in his book ‘PROTEIN - The Basis of All Life’ is that there is only a disease of the Protein of the cell. He maintained that the function of all products (including cell protein) is made up of three portions and their behaviour is attracting, storing and radiating. His theory is based around events occurring when the cell protein in the blood is not completing these three activities effectively – it is not attracting food, not storing it and, therefore, not radiating it to the body in a balanced way - hence the ‘diseased’ state. 

He was educated at the Medical College of St Bartholomew's Hospital 

“Dr McDonagh’s theories are perhaps 200 years ahead of his time – and were not accepted by medical convention, generally. I wonder if many would accept such theory today.”
