William Roberts – The cause of heart disease – It is the cholesterol

William Roberts is a leading cardiovascular pathologist. He is the current editor (at 2018) of the American Journal of Cardiology— a position he has held since 1982. He has published over 1,500 articles. Roberts served as the first head of the pathology service at the National Heart, Lung, and Blood Institute at the National Institutes of Health from 1964 to 1993. He has been located at Baylor Heart and Vascular Institute and Baylor University Medical Center in Dallas, Texas since 1993.

He wrote:

Most physicians, I believe, consider atherosclerosis to be a multifactorial disease, and the greater the number of atherosclerotic risks factors present, the greater the chance of having an atherosclerotic event. I am in the minority in believing atherosclerosis to be a unifactorial disease ¹ ²

Risk Factors

Roberts notes that most physicians believe that the following are risk factors for heart disease but only high cholesterol is the cause.

smoking
diabetes mellitus
high blood pressure
family history
obesity
stress
inactivity
inflammation
high cholesterol

He states that if cholesterol is less than 150 mg/dL (3.9mmol/L) then you will not have a heart attack irrespective of the other 8 risk factors. He also states that HDL cholesterol is largely irrelevant despite the importance placed on it by many health organisations.

The Cause of Atherosclerosis

Roberts states four reasons why cholesterol is indeed the cause – and only cause – of heart disease. ³

It is important to note that the other factors are important in regard to our health – they are simply not implicated in heart disease.

Animal trials

It is easy to produce plaques in animals by feeding high cholesterol or high saturated fat diets. It is not possible to produce plaques in carnivores (rats, dogs, cats) unless the thyroid function in disabled as carnivores convert cholesterol into bile salts which are excreted.

Despite frequent claims that heart disease is an inflammatory disease, inflammation is “infrequent in plaques of coronary arteries.” Inflammation can result from a multitude of illnesses and injuries.

Cholesterol is present in plaques

Cholesterol is present in plaques along with white blood cells (that have engulfed oxidised cholesterol), other lipids and calcium deposits.

Populations with high cholesterol have high levels of heart disease

Many studies including the Seven Countries Study, Seven-day Adventist studies and Framingham studies have shown that higher levels of serum cholesterol is associated with higher levels of cardiac events.

Lowering cholesterol results in a decrease of atherosclerotic events

Lowering serum total cholesterol and low-density lipoprotein (LDL) cholesterol levels decreases the number of cardiac events and plaque size is decreased. ⁴

Richard asked for blood tests before we started the program. My blood pressure was high and had been for some time. It had become border line medication. From the first appointment with Richard I removed meat, dairy and eggs from my diet and followed his advice – whole foods, plant based. I had a doctor’s appointment two days later to address my blood pressure and I was astounded that my blood pressure was normal.

I did Richard’s course in April (2007). Since then I have given up eggs and dairy. I was not eating meat. I continue to make my own wheat bread. I was taking diabetic and arthritic medications.

With some additional help from a local naturopath, I no longer need any medications at all. I am able to do activities such as gardening which was not possible previously.Read more “I.G. – Hunter Valley”

I was feeling very unwell, difficult to get up in the morning, lethargic and miserable. I had 3 children living at home so it was challenging. After many visits to the doctor, I was diagnosed with type 2 diabetes. It took some time. Because I was not overweight, the doctor assumed that I would not have diabetes.Read more “Mary”

We have just had Richard present for us at one of the Leukaemia Foundation support Groups. The session was both informative and easy to understand, and encouraged group discussion and questions.Read more “Leukaemia Foundation – Hunter Valley”

Richard is wonderfully considerate and helpful and he has been called on many times to assist my Kinesiology Practice. He pays impeccable attention to every detail of the work that he undertakes which he does with enthusiasm and caring. I admire Richard’s skills and abilities and he uses his insight, common sense and intelligence to wisely assist the people with whom he is working to achieve wonderful results.Read more “Loreto”
