What’s the Difference Between a Plant-Based and Vegan Diet?
As a result, a larger selection of plant-based options have become noticeable at grocery stores, restaurants, public events, and fast food chains.
Some people choose to label themselves as "plant-based," while others use the term "vegan" to describe their lifestyle. As such, you may wonder what the differences between these two terms are.
This article examines the differences between the terms "plant-based" and "vegan" when it comes to diet and lifestyle.
History of the Plant-Based Movement
The term "vegan" was created in 1944 by Donald Watson — an English animal rights advocate and founder of The Vegan Society — to describe a person who avoids using animals for ethical reasons. Veganism refers to the practice of being vegan.
Veganism expanded to include a diet that excluded animal-derived foods, such as eggs, meat, fish, poultry, cheese, and other dairy products. Instead, a vegan diet includes plant foods like fruits, vegetables, grains, nuts, seeds, and legumes.
People have become more aware of the negative effects of modern animal agriculture on the planet, as well as the potential negative health effects of eating a diet high in processed meat and choosing saturated over unsaturated fats.
In the 1980s, Dr. T. Colin Campbell introduced the world of nutrition science to the term "plant-based diet" to define a low fat, high fiber, vegetable-based diet that focused on health and not ethics.
What's more, many people don't label themselves as being plant-based or vegan but are interested in reducing their animal consumption and trying foods that are popular on a plant-based or vegan diet.
The plant-based movement began with veganism, a way of living that aims to avoid animal harm for ethical reasons. It has expanded to include people who make dietary and lifestyle choices to minimize harm to the environment and their health.
Plant-Based vs. Vegan
Although a number of definitions are circulating, most people agree upon some specific differences between the terms "plant-based" and "vegan."
What It Means to Be Plant-Based
Being plant-based typically refers specifically to one's diet alone.
Many people use the term "plant-based" to indicate that they eat a diet that either entirely or mostly comprises plant foods. However, some people may call themselves plant-based and still eat certain animal-derived products.
Others use the term "whole foods, plant-based" to describe their diet as being made up of mostly whole plant foods that are raw or minimally processed.
Someone on a whole foods, plant-based diet will also avoid oils and processed grains, whereas these foods may be consumed on a vegan or otherwise plant-based diet.
The "whole foods" part is an important distinction, as so many processed vegan foods exist. For instance, certain varieties of boxed mac and cheese, hot dogs, cheese slices, bacon, and even "chicken" nuggets are vegan, but they would not fit on a whole foods, plant-based diet.
What It Means to Be Vegan
Being vegan reaches beyond diet and also describes the lifestyle that one chooses to lead on a daily basis.
Veganism is generally defined as living in a way that avoids consuming, using, or exploiting animals as much as realistically possible. While this leaves room for individual preferences and barriers, the overall intent is that minimal harm is done to animals through life choices.
In addition to excluding animal products from their diets, people who label themselves as vegan typically avoid purchasing items that were made from or tested on animals.
This often includes clothing, personal care products, shoes, accessories, and household goods. For some vegans, this may also mean avoiding medications or immunizations that use animal byproducts or have been tested on animals.
"Plant-based" refers to a diet that solely or primarily consists of plant foods. A whole foods, plant-based diet also excludes oils and processed packaged foods. "Vegan" indicates that animals are excluded from the diet, products, and lifestyle decisions.
You Can Be Both Plant-Based and Vegan
It's possible to be both plant-based and vegan, as these terms are not meant to divide people based on the lifestyle they choose.
Many people may start out as vegan, avoiding animal products in their diet primarily for ethical or environmental reasons, but then adopt a whole foods, plant-based diet to achieve their health goals.
On the other hand, some people may start out eating a whole foods, plant-based diet and then decide to expand into veganism by aligning the rest of their lifestyle, avoiding animal products in other non-food areas as well.
Being plant-based and vegan can go hand-in-hand. Some people may start out as one and adopt the intentions or ideas of the other approach, applying ethical, health, and environmental considerations to their lifestyle as a whole.
The Bottom Line
Many people are choosing to reduce or eliminate the number of animal products they consume. While some people choose not to label their dietary choices, others consider themselves plant-based or vegan.
"Plant-based" typically refers to one who eats a diet based primarily on plant foods, with limited to no animal-derived products. A whole foods, plant-based diet means that oils and processed packaged foods are likewise excluded.
The term "vegan" extends to one's lifestyle choices beyond diet alone. A vegan lifestyle aims to avoid causing harm to animals in any way, including through products used or purchased.
Someone who is vegan also tends to take into account the potential negative environmental effects of animal products.
While these two terms are fundamentally different, they share similarities. Additionally, both are increasing in popularity and can be healthy ways of eating when planned properly.

Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
