A preposterous and ill-informed statement. Doctors continuously study to improve their skills. They have to. Medical science is changing relentlessly and quickly.
That's what one would expect, Peter. And there indeed are some doctors in that category.
Unfortunately, in my limited experience, most doctors are not keeping up with rapidly changing medical science. Even worse, they continue to spread out some of the old myths that can harm their patients.
Here are two examples of such practices:
1. Most doctors and even some nutritionists are still advocating consumption of milk and other dairy products which has been proven as harmful for bones, heart and weight gain, including increase of cholesterol, and for prostate and ovarian cancers.
Besides humans (and companion animals who are fed by humans), no species drinks milk beyond their natural age of weaning or drinks the milk of another species. Cow’s milk is suited to the nutritional needs of calves, who have four stomachs and gain hundreds of pounds in a matter of months—sometimes weighing more than 1,000 pounds before they’re 2 years old. Cow’s milk does not suit the nutritional needs of humans, so it’s no wonder that consuming it and its derivatives causes us so many problems.

Most orthopedic surgeons and dentists still recommend that any person who underwent a heart or prosthetic joint implants should take antibiotic prophylaxis prior to any dental procedures (for 2 years after such surgery or even for life), incl. routine procedures, such as teeth cleaning, despite the latest findings that shows that the risk of adverse reactions to antibiotics generally outweigh the benefits of prophylaxis for many patients. Even the Canadian Dental Association stopped recommending taking antibiotics prophylaxis before the dental procedures, except in some special situations.
This is based on a review of scientific evidence, which showed that the risk of adverse reactions to antibiotics generally outweigh the benefits of prophylaxis for many patients who would have been considered eligible for prophylaxis in previous versions of the guidelines. Concern about the development of drug-resistant bacteria also was a factor.
