We’ve all experienced it.
We invite a friend to dinner, only to learn that she is the dreaded V-word.
We have a vague sense of what it means, but we’re left with so many questions?
Is it healthier?
Will you sit on my leather couch?
Can we still go to Taco Bell?
In a world of health magazines and Planet Fitness commercials,
many people want to learn more about nutrition and which diets are the healthiest.
Wherever you go, no one can escape the growing vegan phenomenon,
so we thought it would be fun to explore it further in this episode
of The Infographics Show; Vegans vs Meat-eaters.
A vegan is someone who follows a diet that contains no animal meat, fish, eggs,
dairy products, or any other food that comes from animals.
They differ from vegetarians, who generally still eat dairy and eggs
as part of their diets.
Vegans also typically abstain from using any other products that come from animals,
such as honey and leather jackets.
Back in 2008, vegans only accounted for around 0.5% of the US population,
or about 1 million people.
As of polls taken in 2014, vegans now make up roughly 2.5% of the population.
At least in the United States, women seem to be far bigger fans of veganism,
making up around 79% of vegans.
The number of meat eaters obviously far outweighs
the number of vegans throughout the world,
with the highest concentration of vegans being in Israel
at only around 5% of their population.
By not consuming any animal products,
vegans follow a dietary path similar to an herbivore.
Herbivores are animals that feed exclusively on plants,
such as cows, giraffes, and adorable deer.
Meat-eaters are typically omnivores,
which means that they eat both plants and animals.
The term comes from the latin words Omni,meaning “all or everything,”
and the word Vorare, which means “to devour.”
So basically omnivores are down to eat whatever.
Most meat-eaters don’t solely eat just meat, like a carnivore would do.
That is, unless you’re Ron Swanson from Parks and Rec.
Then it’s beautiful bacon and sizzling steaks all day!
So humans are widely thought of as natural omnivores,
but some believe that humans are at their optimal health
when following the dietary habits of an herbivore.
People often cite potential health benefits and ethical dilemmas
as the main reasons to go on a vegan diet.
We won’t get into the ethics today,
but we are curious about the health differences
between vegans and their meat-eating friends.
People on a vegan diet tend to be leaner.
In a cross-sectional study of nearly 40,000 adults,
meat-eaters had the highest mean body-mass-index, or BMI.
Vegetarians were in the middle and vegans had the lowest.
Based on several studies from Finland, some scientists have suggested that
vegan diets may be helpful in the treatment of rheumatoid arthritis.
Vegans also appear to have lower rates of hypertension
than both meat-eaters and vegetarians.
Vegans also typically have lower cardiometabolic risks
for conditions like heart disease or strokes.
The problem, however, doesn't seem to be with meat itself,
but rather with the quality of meat.
Recent findings have found that coronary heart disease problems
do not seem to be linked with red meat and saturated fats like previously thought,
but rather with processed meats.
Based on a study of nearly 1.25 million people consumption of processed meats,
not simply red meat, was associated with higher rates of coronary heart disease.
From an evolutionary standpoint,
meat-eating omnivores also seem to be the reason
behind the growth of our larger, more intelligent brains.
This is the result of the higher protein content associated with meat consumption.
The American Dietetic Association, or ADA, states that
the protein from plants can easily meet and exceed protein requirements,
and that being an omnivore merely increases the amount of protein sources
a person can have by including animal meat.
Obviously, protein is important to both bone health and muscle mass.
One study even found that women who ate meat
had higher amounts of muscle mass than their vegetarian counterparts,
even if the protein intake was the same.
While there certainly may be some health advantages in going vegan,
there seems to be some common deficiencies in the diet.
One of these deficiencies is with the vitamin B-12.
The ADA states that there are no natural plant foods
that contain any significant amount of the vitamin.
Vegans can still get it, but they need to take a vitamin or consume fortified foods
like soy milk and certain breakfast cereals.
Omega-3 fatty acids are also very difficult to come by on a vegan diet,
but this can be overcome through the consumption of algae supplements.
With vegans requiring supplementation to meet their nutritional needs,
it supports the claim that veganism is unnatural,
but that doesn’t necessarily mean it's unhealthy.
At this point, some of you may be wondering which diet leads to longer life spans.
For that information, we turn to Okinawa.
The traditional Okinawan diet is typically regarded as the best for health and longevity,
with the Okinawan islands having the greatest concentration of centenarians in the world.
An archipelago hundreds of miles off the coast of Japan,
Okinawa has about 740 centenarians out of its population of 1.3 million people.
While their diets have been changing recently due to globalization
and factors like fast food chains,
the traditional Okinawan diet is made up of large amounts of plant-based carbohydrates
Although they are primarily vegans,
traditional Okinawans still eat meat on special occasions,
usually pork, as well as small amounts of fish on a weekly basis.
This doesn’t prove that small amounts of animal products are vital to good health,
but it does hint that the optimal human diet
can be achieved without going completely vegan.
That said, many health organizations, including the ADA,
state that well-planned vegan diets are healthy and nutritionally adequate,
and may provide health benefits
in the prevention and treatment of certain diseases.
It seems like no matter what your dietary preferences are,
a healthy lifestyle can be achieved on or off a vegan diet.
Are you or would you ever consider becoming a vegan?
Why or why not?
