GET YOUR PROTEIN FROM PLANTS, NOT MEAT, IF YOU WANT TO BE HEALTHIER. TRUE OR FALSE? SEE
FOR YOURSELF
by Edward Morgan
t�s very easy to come across conflicting information, especially in regards to the
science of health and even more so when it comes to examining meat-based diets in comparison
to plant-based ones. Plant-based diets can help prevent over over 60% of chronic disease
deaths, yet people are still arguing whether veganism is a safe and sustainable diet. This
is largely due to �food industry science,� which is full of bias and false information
that�s constantly used in both our education and health care systems. This is neither a
secret nor a conspiracy theory, as many people within these industries have come out publicly
to address these issues and emphasize the same points.
�It is simply no longer possible to believe much of the clinical research that is published,
or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take
no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades
as an editor of the New England Journal of Medicine� � Dr. Marcia Angell, a physician
and longtime Editor-in-Chief of the New England Medical Journal (source)
A couple years ago, Dr Richard Horton, the current Editor-in-Chief of The Lancet, which
is considered to be one of the most reputable medical journals in the world, stated that
half of all published literature may be false. In his words, �The case against science
is straightforward: much of the scientific literature, perhaps half, may simply be untrue.
Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses,
and flagrant conflicts of interest, together with an obsession for pursuing fashionable
trends of dubious importance, science has taken a turn towards darkness.� (source)
These are important points to consider when talking about science and it�s extremely
apparent in the food system, especially when discussing plant-based diets. We�ve been
hammered with the idea that meat is necessary for good health, even in an age where an enormous
amount of professionals and publications have proven the nutritional benefits of a plant-based
diet. It seems kind of fishy, especially given the fact that several billion animals are
raised and killed for meat production annually, and that�s just in America alone.
Plant-Based Diets Compared To Meat
If we look at �mainstream� science, scientists are only now starting to accept plant-based
diets as a sustainable, healthy option and those doing the research are living, walking
and talking examples of that.
For instance Dr. Ellsworth Wareham, a 100-year-old, and a recently retired heart surgeon who has
been a vegan for half of his life explains that:
�Veganism is a very fine form of nutrition. It�s a little extreme to tell a person who
is using flesh foods that you�re going to take everything entirely away from them. When
I was in practice in medicine, I would tell the patients that the vegetable-based diet
was the healthy way to go, and to keep away from the animal products as much as possible.
People are very sensitive about what they eat. You can talk to people about exercising
relaxation, good mental attitude and they will accept that. But you talk to them about
what they are eating and people are very sensitive about that. If an individual is willing to
listen, I will try to explain to them on a scientific basis of how I think it�s better
for them.� � Dr. Ellsworth Wareham (source)
Another example is Kim A. Williams, M.D., incoming president of the American College
of Cardiology, who also adopted a vegan diet. He often sees patients who are overweight
and struggling with hypertension, type 2 diabetes and high cholesterol. One of the things he
advises them to do specifically is to go vegan. He is also the Chairman of Cardiology at Rush
University Medical Center in Chicago. His enthusiasm for a planet-based diet comes from
his interpretation of medical literature, having cited several studies proving that
people who pursue vegetarian diets lived longer than meat eaters and have lower rates of death
from heart disease, diabetes and kidney problems. (source)
According to Harvard Medical School, �studies are confirming the health benefits of meat-free
eating. Nowadays, plant-based eating is recognized as not only nutritionally sufficient but also
as a way to reduce the risk for many chronic illnesses.� (source)
There are a multitude of studies showing the benefits of vegetarian and vegan diets. For
example, the American Dietetic Association weighed in with a position paper, concluding
that �appropriately planned vegetarian diets, including total vegetarian or vegan diets,
are healthful, nutritionally adequate, and may provide health benefits in the prevention
and treatment of certain diseases.� (Journal of the American Dietetic Association, July
2009) (source)
These diseases include heart disease, cancer, diabetes, and more. Research carried out by
Dr. Dean Ornish, who found that patients who were put on a program that included a vegetarian
diet had less coronary plaque and fewer cardiac events, is also commonly cited.
It�s also important to note that when it comes to science and making �associations,�
it�s crucial to use the Bradford Hill Criteria. We all know that correlation does not mean
causation, and that sometimes, correlation could mean causation. When you have a large
number of studies showing such strong correlations, it�s generally safe to assume that correlation
in certain instances does mean causation. When it comes to plant based diets, there
is no shortage of evidence that clearly outlines their health benefits. Obviously, the benefits
of eating more plant based foods goes far beyond just correlation.
This trend is gaining more scientific inquiry as popularity grows. At least 542,000 people
in Britain now follow a vegan diet � up from 150,000 in 2006 � and another 521,000
vegetarians hope to reduce their consumption of animal products. It is evident that veganism
has become one of the fastest growing lifestyle choices. (Source #2)
One of the most comprehensive studies ever performed on this subject is �The China
Study� conducted by Drs. T. Colin Campbell and Thomas Campbell. Their findings showed
direct correlations between nutrition and heart-disease, diabetes, and cancer, proving
that cultures that eat primarily plant-based diets have lower to no instances of these
diseases and that switching to a plant-based diet can successfully reverse diseases already
established in the body. The China Study is recognized as the most comprehensive nutritional
study ever conducted on the relationship between diet and disease. I highly recommend watching
the documentary Forks Over Knives (available on Netflix), which delves into this in more
detail.
The list of studies goes on and on, and if you�d like to find more information, we
recommend you research this subject yourself as there are far too many studies to include
in this article.
Plant Protein Compared To Vegan Protein
�The protein in animal products is filled with fats and chemicals and all sorts of stuff
that�s harmful to you. When I was competing and stuffing down all that stuff, I had lots
of digestive problems, I was constipated and bloated, just miserable all the time. I don�t
concern myself with protein anymore, because there is enough in what I eat. I am not only
healthy, but I feel better about myself and how I relate to other creatures in the world.�
Above are the words of Jim Morris, one of many competitive vegan bodybuilders, who has
been vegan for most of his life. The last time we saw a vegan bodybuilder he was competing
at this years Olympic Games in Brazil. His name is Kendrick Farris and he was the only
American male weightlifter to compete in the Rio Olympics. You can read more about that
here.
If someone tells you, �I need my protein,� and that�s why they eat meat, they are vastly
misinformed. You don�t need protein from meat to be healthy; in fact, it is the complete
opposite, as plant-based protein is a healthier alternative. Clearly, the bodybuilders adopting
these vegan diets are a great example, but let�s look at what some of the �experts�
have to say.
According to Dr. Deepak Bhatt, a Harvard Medical School professor and Editor-in-Chief of the
Harvard Heart Latter,
�When it comes to getting protein in your diet, meat isn�t the only option. Mounting
evidence shows that reducing meat and increasing plant-based protein is a healthier way to
go. A diet with any type of meat raises the risk of heart disease and cancer, when compared
with a vegetarian diet.� (source)
A more recent study conducted by researchers at Harvard Medical School and Massachusetts
General Hospital followed more than 130,000 people for 36 years, monitoring illnesses,
lifestyles, diets and mortality rates.
They found that substituting between 15g and 19g of animal protein, the equivalent of a
single sausage, for legumes, pulses, nuts and other planet protein, significantly decreased
the risk of early death. Replacing eggs with plant-based protein also lead to at 19 percent
reduction in death risk.
Researchers found that a 10 percent higher intake of meat was associated with a two percent
higher mortality rate and an eight percent higher chance of cardiovascular death.
According to Dr. T. Colin Campbell, mentioned earlier in the article from The China Study,
�What I did during the early part of my career was nothing more than what traditional
science would suggest. I made the observation that diets presumably higher in animal protein
were associated with liver cancer in the Philippines. When coupled with the extraordinary report
from India showing that casein fed to experimental rats at the usual levels of intake dramatically
promoted liver cancer, it prompted my 27-year-long study The China Project, of how this effect
worked. We did dozens of experiments to see if this was true and, further, how it worked.�
In the study, Campbell emphasized the fact that they used the traditional criteria to
decide what is a carcinogen (in regards to animal-based proteins) from the government�s
chemical carcinogenesis testing program. Campbell also stated that, �this is not a debatable
subject and the implications of this conclusion are staggering in so many ways.�
It also showed, among others, that animal protein is very acidic, and leak, and body
takes calcium and phosphorus from the bones to neutralize the acidity.
Below is a video of him explaining some of his findings.
So, Which One Is Better?
Obviously, there is information on both sides. The main point to remember here is that protein
isn�t the same.
Protein is built from building blocks known as amino acids, and our bodies make them in
two different ways. Perhaps not everybody�s body is the same, and some can require what
they need from scratch, or by modifying others.
A short list of amino acids known as theessential amino acids need to come from food. According
to current education, which is largely funded by food corporations who control animal agriculture,
preaches that animal sources of protein tend to deliver all the amino acids we need. What
they leave out about the animal protein is what you just read above.
Other sources of protein lack one or more essential amino acids, but all a vegetarian
or vegan individual needs to do is make sure they contain a variety of protein containing
foods, which will help the body make more protein.
That being said, studies on caloric restriction and fasting have shown that a high protein
intake, too much, is definitely something you don�t want. If you want to learn more
about that, you can check out Dr Valter Longo, or check out some more of our articles on
fasting.
Certain meats have also been linked to several diseases. For example, research conducted
at Harvard School of Public Health has found that eating even small amounts of red meat,
especially processed red meat, on a regular basis is linked to an increased risk of heart
disease and stroke, and the risk of dying from cardiovascular disease or any other cause.
Certain meats are also known to cause cancer, and several other diseases. Replacing these
meats with healthier sources of protein reversed the effects. (source)(source)
Processed foods/meat are also known to cause cancer.
While underconsumption of protein is harmful to the body, overconsumption comes with risks
as well. In the United States, the average omnivore gets more than 1.5 times the optimal
amount of protein, and most of that protein is from animal sources. This is bad news,
because excess protein is turned into waste or turned into fat. This stored animal protein
contributes to weight gain, heart disease, diabetes, inflammation and cancer.
On the other hand, the protein contained in whole plant foods is connected to disease
prevention. According to Michelle McMacken, MD, a board-certified internal medicine physician
and an assistant professor of medicine at NYU School of Medicine:
�[T]he protein found in whole plant foods protects us from many chronic diseases. There
is no need to track protein intake or use protein supplements with plant-based diets;
if you are meeting your daily calorie needs, you will get plenty of protein. The longest-lived
people on Earth, those living in the �Blue Zones,� get about 10% of their calories
from protein, compared with the U.S. average of 15-20%.�
Obviously, there are is a great wealth of information out there, and what I�ve presented
here is just a tidbit. There are also other factors to consider these days as well, such
as industry influence over scientific publications, and more.
