When did your Medical Career begin?
I started my medical career in 1978 as a conventional doctor combining hospital and office work until I came across natural medicine through some colleagues. I gradually shifted the focus of my practice to a more natural approach over the years. To get the complete picture of my medical career evolution, go to https://highlevelwellness.ca/dr-rona/
What type of adversity have you had to overcome in terms of people’s perception of wellness?
The main adversity is overcoming fixed ideas the public has from the world of conventional medical dogma as well as mainstream media propaganda favoring drugs as the answer to all health concerns. Despite much evidence to the contrary, people still believe that cholesterol causes heart disease and strokes, that eggs are bad for you and that vitamin and mineral supplements are dangerous. This is why I have written 12 books on the subject of natural medicine.
This may be a loaded question – but do you think diet or exercise has a bigger impact on wellness?
Diet and exercise has everything to do with wellness. Just google any of my numerous articles on the vitalitymagazine.com web site and you’ll get an excellent idea of what I mean by that.
How often do you exercise and for how long?
I usually exercise by playing about 4 hours of tennis a week and walking at least one hour a day almost every day.
What is your number 1 health tip?
Number one health tip is for adults over 45 to take 10,000 IU of vitamin D a day. Check your blood level once a year with your doctor and optimize your blood level. In Canada, only 3 months of the year will ensure you get adequate vitamin D from sunshine. You will prevent more illness with high blood levels of vitamin D than with any other health measure.
