The term "plant-based" gets thrown around a lot these days. It's often used interchangeably with "healthy," "nutritious," and even "vegan." But here's the reality: Plant-based and vegan diets are not actually synonymous. While vegan diets are generally plant-based, plant-based diets are not, by definition vegan (wait, what?). To offer some clarity, we tapped two registered dietitians to get the scoop on these popular diets—including what they are, what foods they include, and what benefits you can expect.

What does it mean to be vegan & where did the name come from?

The term "vegan" was coined back in 1944, by English animal rights activist Donald Watson, to describe the concept of eliminating animal products for ethical reasons. According to the Vegan Society, the word simply came from the first three and last two letters of "vegetarian."

Since then, people have continued to adopt a vegan diet and lifestyle due to animal welfare concerns, eliminating all animal-based products from their lives. This includes obvious foods like meat, poultry, and fish—in addition to animal products like eggs, dairy, and even honey, explains plant-based registered dietitian and owner of Plant-Based Eats Amy Gorin, M.S., RDN. Most vegans will also eliminate animal-based products beyond diet—such as leather or fur goods, products that use any animal-derived ingredients (think beeswax or gelatin), or anything that involves animal testing.

In addition to the animal welfare concerns, many vegans also choose this lifestyle due to the environmental impact of factory farming, or the health benefits of swapping in more plant foods.

That said, it's important to note that not all vegan diets are healthy ones. "The vegan focus is usually set on avoiding animal products, but the priority is not placed on unprocessed plant-based, whole foods," Miranda Hammer, M.S., R.D., CDN, previously told mbg (think faux meat or processed snacks). The primary requirement for a "vegan" label is the exclusion of animal products—the health and well-being benefits are really contingent on how someone chooses to practice the diet.

What does it mean to be plant-based?

Plant-based diets are often misunderstood. While plant-based eating does include a lot more, well, plants—it doesn't mean you have to necessarily cut out all other food groups. "Ideally, a plant-based diet is one that puts actual plants forward on the plate—think fresh produce, whole grains, plant-derived fats, nuts, legumes, and seeds," says Nicole Rodriguez, RDN.

The term "plant-based" was introduced in the 1980s, by T. Colin Campbell, Ph.D.—a researcher at the National Institutes of Health (NIH) at the time—to describe a vegetable-based diet that focuses on health rather than ethics.

Even though plants are the priority in this eating style, it's a very flexible concept—meaning it's certainly possible to be "plant-based" while still including meat, fish, eggs, and dairy. As Hammer explains, "For plant-based eaters, animal proteins can happily fit into the lifestyle, yet they typically serve as more of a supporting role to your veggies and whole grains."

In addition to being a healthy eating mindset, Gorin says plant-based diets help you feel fuller and more satisfied because you're eating more fiber and more volume. By increasing the number of plants in your diet, you're also likely to provide your body an array of vitamins, minerals, antioxidants, and phytochemicals.

One common concern for both vegan and vegetarian diets is can you really get enough nutrients? Hammer reassures it's more than possible: "As long as you're consuming a healthy balance of protein, vegetables, fruits, and other fiber-rich, whole-food carbs, there's no reason you shouldn't get the vitamins and nutrients your body needs."

Then what does whole-foods, plant-based mean?

A whole-foods, plant-based diet is precisely what it sounds like: a diet that prioritizes whole, unrefined, unprocessed natural foods that come from the Earth—mainly fruits, vegetables, whole grains, seeds, and legumes. At the same time, this style of eating avoids or minimizes highly processed foods—such as bleached flour, refined sugar, and refined oil. People who follow a whole-foods, plant-based diet often minimize animal products, as well.

Nutrition and well-being are the cornerstones of this eating style. As Gorin describes: "This is the healthiest type of plant-based diet that you can follow."

What do vegan and plant-based diets have in common?

The most obvious similarity between vegan and plant-based is you can expect to make plants the cornerstone of your diet. Think fruits, vegetables, seeds, and more ingredients that come directly from the ground.

When plants are the emphasis, both diets offer nutritional benefits, too. "When you're eating more plants, you're taking in a variety of vitamins, minerals, and antioxidants," Gorin says. You'll also likely add more fiber to your diet, which can help promote digestion and gut health, support steady blood sugar levels, maintain energy, and keep you feeling satiated.

"These nutrients can help lower your risk of chronic disease like type 2 diabetes and heart disease," says Gorin. In fact, one study of over 10,000 adults published in the Journal of the American Heart Association indicated those who followed a plant-based diet had a 16% lower risk of having cardiovascular disease and a 32% lower risk of dying of cardiovascular disease. What's more, swapping meat in favor of more plants can help lower blood pressure and cholesterol.

How are they different?

Experts agree that the biggest difference between veganism and plant-based eating is the inclusion of animal products. Although often in moderation, a plant-based diet may include animal products such as meat, fish, dairy, and eggs. However, by definition, a vegan diet excludes all animal products.

Are there foods that are vegan but not plant-based?

For the most part, the answer is no—after all, most vegan diets do generally consist of fruits, veggies, legumes, and other plants.

However, while plant-based diets put health at the forefront, technically that's not the basis of a vegan diet. So while a bag of chips may qualify as "vegan," that processed snack may not fit into a plant-based lifestyle. (Yes, we're getting very precise here.)

Are there foods that are plant-based but not vegan?

"Plant-based is open to interpretation and flexibility, whereas veganism is not," Rodriguez says. She continues that someone who eats a plant-based diet may consume some eggs, dairy products, and occasional meat—all of which are off-limits in a vegan diet. 

Gorin says wine and honey are also examples of plant-based but not necessarily vegan food items. "Honey is [usually] not part of a vegan diet because the health of the bees that produce honey may be harmed through conventional honey production," she says. And a standard bottle of wine uses a clarification process that uses animal-based products (like casein, albumin, gelatin, or isinglass). "If you're looking for a vegan wine, there are many out there that use alternative ingredients for this process."

The bottom line.

While a vegan diet is more specific in its definition, a plant-based diet is more flexible—and you can modify it to your liking, as long as plants are at the forefront. Both diets are full of nutritional benefits that we can all benefit from, so it really comes down to individual preference.
