About Bernard Preston

Hello. About Dr Bernard Preston, DC will tell you about me.

Should you be interested in my qualifications to write with any authority, here you will find my background; firstly for seven years as a high school teacher of physics, chemistry and mathematics to seniors.

Then followed by over forty years in practice as a DC in South Africa and the Netherlands.

Greater well-being and a life without medication do not drop spontaneously from the heavens; they come as one would expect to those who who are prepared to learn about and follow the edicts of nature.

How many couples in their eighth decade do you know who enjoy a life without medication; it can be done.

If we do not treat Brother Ass kindly, as the celebrated St Francis of Assisi called his body, then he may well turn around and bite us.

"Human judges can show mercy. But against the laws of nature, there is no appeal. "

Bernard Preston

Graduating with a BSc, majoring in physics and chemistry, followed by a BEd, I went on to teach high school science for seven years before moving on to Chicago to study spinal-manipulation specifically, and wellness more generally.

It's often said that your education begins the day you graduate; nearly forty years in practice as a DC confirms that truism.

About us gives more about the editorial panel.

For ten of those years I was a part-time lecturer at DUT, South Africa's first university-level course on spinal manipulation.

Radiology and technique were the primary courses taught, and in the afternoons four hours as a clinician guiding and directing young interns.

About details Bernard Preston's qualifications and experience as a DC; one who is completely obsessed with natural-living and caring for the environment.

Natural living and environmental issues are completely intertwined and dependent. One cannot expect to be robust and strong if one is living in toxic surrounds, and consuming food and drink laced with chemicals.

The word organic is so abused and meaningless today; it's best to presume that it is just a marketing tool, and make the decision to grow as much of your own food as you possibly can. And become personally acquainted with local farmers, and beekeepers, for example.

And I recommend that you harvest your own rainwater; chlorine is a very toxic chemical. Are we quite certain it's not one of the underlying causes of our poor status?

I have no formal education in environmental affairs, other than that gleaned from over half a century of commitment to keeping bees, making compost and growing vegetables. Learning doesn't only occur in the classroom; on the job training will teach those willing to learn from the hard-knocks of a commitment to backyard permaculture.

The major in organic chemistry gave me the background to understand and write about subjects like the proline in gluten, and why it gives the colon of some people so much grief.

Current ongoing education consists of an in-depth course given by Professor Tim Noakes, et al, on the virtues of a diet with close to zero refined carbohydrates, and far less starch in general, in the management of diabetes and obesity. 

I am the author of six published books; find them in the navigation bar.

The family

Amongst these South African chiropractic pioneers you will find both of Bernard Preston's parents.

Both my parents were DCs, graduating in the USA in 1940. Both of them are in this group of South Africans taken in 1963, with eminent Dr Jo Janse in the front row.

My daughter is a DC too.

Help from a DC

For twelve years I have developed the authoritative premier site[1] on spinal manipulation having over 450 pages. It's been a labour of love based on my academic background and clinical experience.


Now in my senior years I have the time and energy to focus on my passion; prevention of lower back pain, and poor wellness in general.

The short answer is to exercise daily and commit to enjoying a diet of unrefined and where possible organically-grown food.

It's no coincidence that at 74 years of age, neither I nor my wife take any chronic medication. We are both in excellent shape.

Attention deficit

The one malady that I have suffered from my whole life is difficulty retaining focus on a subject; it soon bores. It drove my teachers as a child scatty.

Whilst attention deficit Bernie remains a problem, to a large extent I have mastered it without medication. Today as a child I would certainly have been put on Ritalin, despite all the dangers[2].

I believe a commitment to wellness has been the secret to mastering this malady, especially in the domain of exercise and food very low in refined starches and sugars.

Few things have been a greater challenge than being a blood donor.

Blood donor tips.

There is a common but misguided belief that one can only get sufficient iron if you eat red meat; and calcium if you enjoy dairy products daily.

Yet whole grain, legumes and vegetables are loaded with these minerals. I have never been tested for low iron on donating blood. The good wife does not suffer from osteoporosis or anaemia.
