How does a plant-based diet prevent disease? A short lesson

Posted by Jenn on January 31, 2011


There is an ever-growing mountain of evidence substantiating the numerous health benefits that a plant-based diet provides.

Peer-reviewed medical paper after peer-reviewed medical paper published in the most well-respected of journals have shown that a plant-based diet free of meat and dairy products is the single most powerful tool we have at our disposal to prevent and fight disease.

Not only can heart disease and diabetes be prevented but the disease progression can be stopped and reversed. If that wasn’t enough there is a multitude of research showing how the consumption of a plant-based diet’s can prevent cancer, dramatically reduce cancer recurrence rates, reduce cognitive impairment as we age (Alzheimer’s Disease and Dementia) and reduce osteoporosis in addition to a myriad of others. This being the case, how exactly does something as seemingly simple and low-tech as one’s diet manage to do these things?

The short answer is this: via a gas called nitric oxide which is produced by our endothelial cells.  The problem with this very brief explanation is that most people have never heard of nitric oxide, much less endothelial cells. Consequently, that probably isn’t going to help most people understand how the very important the daily decision to eat a plant-based diet is able to accomplish such incredible feats.

What the heck are endothelial cells? and what the heck is Nitric Oxide (NO)? and how do they accomplish the mammoth task of keeping us healthy?

Endothelial cells are the thin single-layer of cells that line the interior surface of all blood vessels.  They are the cells that come in direct contact with blood flowing through our cardiovascular system.  A “healthy” endothelium can be best described as having like a Teflon coating on the vessels’ inner walls; this non-sticky quality enhancing the flow of blood.  An “unhealthy” endothelium, by contrast, acts like Velcro, grabbing white blood cells, platelets and cholesterol and packing them against the inner wall of the blood vessels narrowing them = causing the vessels to thicken over time, thereby inhibiting the flow of blood. This accumulation of “material” leads to the formation of  what are called atherosclerotic “plaques”.

healthy vs unhealthy endothelium

A healthy endothelium is not being covered by any plaque and therefore has the ability to release many beneficial substances into the blood stream.  An unhealthy endothelium  eventually narrows and thickens and resultantly loses flexibility.  The vessels can no longer expand as they should when the heart pumps blood through them. Pumping blood into stiff arteries containing plaque increases resistance to blood flow causing the heart to work harder. Your blood pressure must increase to pump the same volume of blood through these vessels.

That being said, what then determines the overall health of our endothelial cells that make up our endothelium? In other words what makes our endothelium non-stick or sticky?

That is where Nitric Oxide (NO) comes in. Remember, a healthy endothelium is able to release many beneficial substances into our blood stream.  (Note: we are born with a very healthy endothelium which means until we create an environment in which plaques are created, our vessels are healthy, slick and without plaque)  Nitric oxide is one of these substances.  Nitric oxide has a number of important functions.  One of its primary functions according to Dr. Louis J. Ignarro, the 1998 Nobel Prize winner in Medicine,

“…is to help keep the arteries and veins free of the plaque that causes stroke and to maintain normal blood pressure by relaxing arteries, thereby regulating the rate of blood flow and preventing coronaries (heart attacks)”.

He goes on to explain that,

“Nitric oxide is the body’s natural cardiovascular wonder drug”.

NO accomplishes this by controlling muscle tone of the blood vessels which directly impacts blood pressure control, inhibiting the aggregation of platelets and other particulate such as cholesterol and white blood cells.

Other functions worthy of note include: facilitation of proper kidney function, aiding in the transmission of messages between nerve cells, helping the immune system fight  viral, bacterial and parasitic infections as well as tumors, peristalsis, regulating inflammation, lowering of cholesterol levels and penile erection. Let’s discuss one of these functions in more detail to illustrate.

For example, erection of the penis during sexual excitation is mediated by NO release from the endothelial cells lining the blood vessels of the penis.  The NO release from the endothelial cells cause the blood to pool in the adjacent blood sinuses producing an erection.  Thus, if NO cannot be produced (or produced in sufficient amounts) as the result of a damaged endothelium, then an erection cannot occur. This is why difficulty getting or maintaining an erection is indicative of impending or active heart disease (= ample accumulation of plaque).  If you are currently experiencing impotence, it would be a very good idea to see your doctor such that he or she can discern the cause.

How a poor diet results in poor erections

Causes of endothelial damage  and resultant plaque formation:

  • Smoking – it decreases good cholesterol (HDL) and increases bad cholesterol (LDL) that damages your endothelial cells. Further, nicotine directly damages endothelial cells and the carbon monoxide from cigarette smoke damages the endothelium too.
  • A high fat, high cholesterol diet (particularly animal fat from meat and dairy products; plants do NOT have cholesterol) – LDL directly damages endothelial cells.
  • A diet low in fiber content (animal products do NOT contain any fiber) – High fiber foods absorb bile salts that your body uses in digestion.  Your liver manufactures bile from cholesterol.  Thus, high fiber foods are a natural way to reduce bad (LDL) cholesterol.
  • Diabetes – When blood sugars are beyond the normal range it causes oxidative stress to the endothelial cells resulting in damage to them.
  • Being overweight or obese – Fat cells store vitamin D and vitamin D inhibits vessel calcification (plaques eventually get harder as a result of calcification). Thus, losing weight or being at a healthy weight keeps the vitamin D in your system allowing for utilization thereby preventing plaque calcification. Read the rest of this entry »

The Merits Of A Plant-Based Diet, Just The Facts Please

Posted by Jenn on December 28, 2010


Author: mark brohl

When it comes to a healthy diet many folks with whom I have spoken attempt to deny plain facts and plain statistics by citing one example that they hope will refute the obvious truth.

The vast majority of evidence clearly shows that a plant-based diet heals, while an animal- based diet leads to cancer and heart disease among other unfortunate health issues.

Therefore if you are having an intelligent discussion about health matters and you become overwhelmed by the facts please know that the facts do not change nor do they need adjusting just because you cite the case of your dear great grandmother as an example of one who ate bacon and eggs for breakfast, bologna for lunch, meat loaf for dinner, and smoked 2 packs of regular Camels every day and still lived to be ninety two.  This is the exception and certainly not the rule and should not be taken too seriously as a statistic since it would be difficult to find a significant amount of other individuals who could boast the same.  It should also be noted that just existing for ninety two years when in reality the last thirty of them were spent in pain racking illness does not really make a person a poster child for the merits of bacon and cigarettes.

Actually medical evidence is clear, consistent and astonishingly one sided.  Vegetarians are far less likely to suffer from cancer, heart disease, diabetes, or osteoporosis.  They are also far less prone to obesity.

The largest study of its kind ever conducted was the China-Oxford-Cornell Study which revealed that a typical meat eater would be over fifteen times more likely to die from heart disease, and that women were five times more likely to suffer from breast cancer than folks who obtained no more than five percent of their protein requirements from eating animals and their by-products. This is just one study, and as previously stated the evidence is just ridiculously one sided in favor of refraining from animal foods and adhering to a plant-based diet.

These facts are not meant to infer that vegetarians cannot practice unhealthy eating and lifestyle choices, because they certainly can.  If one refrains from eating meat but instead opts for junk food and soda pop, never exercises, and does not drink enough water or get enough sleep such a person should not imagine that not eating meat is going to save his or her health.  Even if he or she were to enjoy excellent health and vitality throughout a long life this would not be a normal outcome to such a deficient lifestyle or health program.

The bottom line is that if you are a meat eater your chances of becoming a cancer, heart disease, or diabetes statistic raises exponentially, while also being far more likely to suffer osteoporosis and other diseases than those who refrain from eating animal foods.  And of course you have a far greater chance of becoming obese also.  Whether you stick your head in the sand, pull the covers over your head, or put your hands over your ears and close your eyes, it will not change the fact that your lifestyle and eating habits are killing you.

About the Author

I am passionate about health issues, and the state of the health of our wonderful America. I believe the American diet is literally killing us and that a steady flow of money and perks from the meat, egg, and dairy industries to the U.S. government is the reason we have had a long sustained brainwashing campaign that has precipitated the shift from a predominantly plant-based diet to an animal-based diet. The result has been an unprecedented increase in heart disease, diabetes, stroke, and cancers of all varieties. I believe Americans are suffering from a lack of truthful information concerning our diets. I enjoy writing motivational articles that will help to correct the problem regarding this lack of information and also examine the prevailing misinformation in the light of truth.

Diabetes? Not on a Plant-Based Diet!

Posted by Jenn on December 21, 2010


(Source: By: Silvie Celiz; 11.01.10; Original URL: http://hlifemedia.com/2010/11/diabetes-not-on-a-plant-diet/)

Nearly 24 million children and adults in the Unites States have diabetes. That is not counting the 57 million Americans that have pre-diabetes and are at risk of developing type 2 diabetes, and the other 5.7 million who don’t know they have it. The American Heart Association estimates that 59.7 million Americans 20 years and older have pre-diabetes, a condition that more than doubles the risk of death due to heart attack. The worse part is that the death rates due to diabetes continue to increase since 1987. Here is the good news: Type 2 diabetes and pre-diabetes can be reversed with NO DRUGS by getting informed and adopting a plant-based diet.

Heart disease and stroke are the number one causes of death and disability among people with type 2 diabetes. In fact, at least 65% of people with diabetes die from some form of heart disease or stroke. It’s astonishing that the national cost of diagnosed diabetes in the United States is $174 billion, with direct medical costs reaching around $116 billion, and that the total diabetes-related cost could exceed $218 billion (just in the U.S.), while all these can be prevented by your food choices. The most common form of diabetes is type 2, and practitioners like Dr. Gabriel Cousens have confirmed that it can be reversed and prevented simply by eating an unprocessed, vegan, whole foods, plant-based diet with a high emphasis on live (raw) foods. That simple. Diabetes can easily be reversed and your body healed if you change your lifestyle.

So, what is diabetes exactly? Diabetes is a metabolic disorder by which the body does not produce or properly use insulin. Insulin is a hormone that allows the body to use glucose for energy. The body produces glucose from the food you eat.  Diabetes can also be described as an ongoing inflammation, which can affect all organs. Research from scientists at the University of California, San Diego, and Switzerland’s University of Fribourg discovered that inflammation provoked by immune cells calledmacrophages leads to insulin resistance and then to type 2 diabetes. We might want to watch foods that contain gluten (especially the very popular vegan protein seitan, which is pure gluten) because it is pro-inflammatory. In the long term, the development of diabetes can damage your eyes, kidneys, nerves, and heart. Read the rest of this entry »
