Two Kinds of Cardiologists

In Part 1 we discussed just a few of the downsides and potential risks of consuming meat and other animal foods. In Part 2 we explain why nutrition-minded physicians are giving up meat and becoming vegans.

More Research Than Ever

We live in amazing times. Scientists and researchers are conducting more quality studies and are discovering more about how our body works. There are many studies and meta-analyses of studies being conducted the glut of useful data is almost overwhelming. We now understand the direct correlation between meat consumption and rates of arthritis and dairy consumption in relation to osteoporosis. (Countries where consumption of dairy products is highest have the highest rates of osteoporosis, not the lowest as advertisers have promised.) Countless people are suffering because they believed what the government and advertisers are telling us.

The most important external factor that determines your health on every level is what you choose to eat, drink and supplement. Many people would prefer to believe that all foods and beverages are benign or neutral in their effect, but this simply is not true. Once we understand our basic physiology we are left with the fact that we are herbivores, not carnivores or omnivores. The biological structures and functions of carnivores are entirely different from ours, and over time we pay a dear price for consuming animals, their milk and eggs. Just because a substance contains vitamins, minerals, amino acids and fats doesn’t automatically imply that that substance is health-giving. There are many other factors to be considered.

Heart Disease – America’s #1 Killer

Atherosclerosis is a condition where the arteries become narrowed and hardened due to a buildup of plaque around the artery walls.  According to William C. Roberts MD, the Editor in Chief of the American Journal of Cardiology for over 25 years, contributing factors such as smoking, diabetes, hypertension, inactivity and overweight cannot cause atherosclerosis unless there is excessive cholesterol present. Without excessive cholesterol, atherosclerosis cannot form in our arteries. Cholesterol comes from saturated fats found in animal foods and is the cause of atherosclerosis, particularly in those who lack sufficient exercise. This is known: vegetarians have a 32% lower risk of hospitalization or death from cardiovascular disease than people who consume meat and fish.

“Because only humans get atherosclerosis, and atherosclerosis is a disease only of herbivores, humans also must be herbivores.” William C. Roberts, MD

Whole foods plant-based diets have been studied for decades. Dr. Dean Ornish, Dr. John McDougall, Dr. Michael Klaper, Dr. Ancel Keys, and Dr. Nathan Pritikin are some of the best-known names among nutrition-based doctors. Dr. Kim Williams MD, the former president of the American College of Cardiology who has been a vegan since 2003 is quoted as saying:

“There are two kinds of cardiologists: vegans, and those who haven’t read the data.”

Dr. Williams’ switch to a vegan diet was inspired by the medical literature and observational studies of tens of thousands of people following vegetarian and vegan diets and living longer than meat eaters, while also having lower rates of heart disease, diabetes, and kidney problems, to name a few. This is referred to as an Evidence-based Diet.

Another study by researchers at the Icahn School of Medicine at New York’s Mt. Sinai Hospital involved more than 15,000 people with no known heart problems and compared five dietary patterns. These included:

  • Convenience (red meats, pastas, fried potatoes, fast food)
  • Plant-based (dark green leafy vegetables, fruits, beans, fish)
  • Sweets (desserts, breads, sweet breakfast foods, chocolate, candy)
  • Southern (eggs, fried food, organ meats, processed meats, sugar-sweetened beverages)
  • Alcohol/salads (salad dressings, green leafy vegetables, tomatoes, wine, butter, liquor).

The results: Those who adhered to a plant-based diet had a 42% decreased risk for heart failure over the study’s four years, compared to those eating fewer plant foods, even after adjusting for the effects of age, sex, race and other risk factors. Those following the other dietary patterns saw no such reduction.

Vitamin C

Humans, unlike carnivores, lack the ability to manufacture vitamin C inside our bodies because we evolved eating lots of fruit. We must ingest fruits and vegetables in order to get adequate vitamin C daily or else a severe, and potentially deadly, deficiency can manifest rather quickly. Remember ‘scurvy” sailors whose teeth would begin loosening after a few weeks out to sea without it?  That was the reason barrels of limes were always on board ship.

Plants create antioxidants such as vitamin C to protect themselves from the environment, and humans evolved to eat plants to benefit from these antioxidants. Humans became dependent upon high-antioxidant plant foods to boost our own defenses. There is also a strong vitamin C correlation related to a healthy heart and the healthy functioning of our blood vessels. (Regarding vitamin B-12 – since this is the only deficiency from avoiding animal-based foods, taking a small supplemental dose on a regular basis is a simple and inexpensive way to prevent deficiency symptoms.)


This is another requirement of the human body, as well as the bodies of all other herbivores. Sufficient dietary fiber is one of the essentials for a healthy body and brain. Carnivores have no need for fiber because their digestive systems are completely different. Humans are completely dependent upon adequate dietary fiber for its effects in feeding and supporting our beneficial gut flora to flourish and to support healthy elimination. Meat, eggs and other animal foods deliver no fiber, but all whole plant foods are abundant in fiber. The benefits of a high fiber diet are finally becoming understood recently due to research by geneticists and biochemists studying the gut microbiome.
