How to make Diseases disappear

A provocative title but... can you really make a disease disappear? Is Dr Rangan Chatterjee a magician?
No, he is not -  as he explains at the start of this informative and moving presentation - but he believes he can tackle the root causes of many chronic diseases, from depression to Alzheimer's, and effectively make them go away.
Rangan Chatterjee wants to change the way we look at illness and how medicine is practiced for the future. His groundbreaking BBC TV show, Doctor In The House, gained him much acclaim from patients, his contemporaries and the media, and in this Tedx talk, he gets personal.
"Our genes load the gun, but it's our environment that pulls the trigger", he says.
"Type 2 is a blood sugar problem... but it's not. It's only a symptom, so we need to treat the root cause."​
In this compelling talk, Dr Chatterjee shows that what Americans would call a holistic approach can reverse the path of many chronic diseases. I once questioned him on the use of this word holistic, which in the UK sounds a bit out-there. He prefers to speak of a 360 degree approach to health but there's no simple expression for what he advocates other than by comparison to what it is not.
Perhaps a holistic approach is better described as being "curative" (problem oriented) or "etiological", rather than "palliative" which is symptom oriented.
Did I hear you saying: "Whatever?" OK - here's my analogy: In the world of business, we sometimes borrow the medical term when we seek out a cure for our problems; put differently, we try to get ahead of the curve by looking for a 'curative' solution.
So let's support Dr Chatterjee's sensible and cost-effective curative approach by spreading the word and showing this video to many others.
