Vegan For Beginners: A Dietitian Written Guide (2025)

This guide- all about going vegan for beginners, is written by both a vegan identifying dietitian!

I’m not just going to cover important points about stuff I have credentials in (food and nutrition).

In order to be great vegan advocates, we’ve got to know our stuff!

So in this detailed guide, you’ll find info about nutrition, non diet lifestyle factors, and (not so secret) tips on how I navigate being vegan in a non vegan world.

I hope you enjoy reading this as much as I enjoyed writing it!

What Does it Mean to “Go Vegan?”

Let’s start with the basics. What does it actually mean to ‘go vegan?’

Maybe it’s best to start with what veganism isn’t, because there is this major misconception about what veganisim is.

Veganism is not:

• A diet,
• a fad or,
• thing that you only do on the weekends.

Veganism is a philosophy rooted in non harm towards non human animals (as realistically as possible).

This philosophy inspires the lifestyle change that we call ‘vegan.’

While the concept of non harm toward animals began before the definition, here’s is more ‘modern day’ way The Vegan Society defines “Veganism”:

“Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals.”

https://www.vegansociety.com/go-vegan/definition-veganism

In summary, vegans try to practice a lifestyle that reduces harm to animals as practically as possible.

Ways in which vegans reduce exploitation of animals through lifestyle often includes:

• Vegan diet
• Avoiding entertainment that exploits animals (such as circuses)
• Avoiding purchases that involve animals (such as leather jackets)

So, veganism is not merely a diet!

But why does the diet part get so much press?

Probably because it is the hardest part to change!

That’s why most of this guide will focus mostly on food and nutrition.

Who Can Be Vegan?

Many of us can be vegan.

Still, there are times in which some components of veganism (as mentioned via the definition above), might be exceedingly difficult or not appropriate.

To illustrate: Some folks can’t access a variety of wholesome plant based foods and vitamin B12 depending on their location (some of the keys to a healthy vegan diet).

That’ why you’ve probably heard that vegan activists aren’t educating remote places about veganism!

Also, individuals with certain conditions, may have a harder time, or a vegan diet may not be healthy.

For example, those with eating disorders or lots of food allergies should especially talk to their health care provider about whether exclusion of all animal products is appropriate.

There is so much controversy around this subject, but the important thing to remember here is this: there is no vegan police or ‘levels of vegan!’

Helping animals in other ways, such as donating to reputable animal charities, volunteering your time at animal shelters, or even making some plant based decisions etc, is good for animals.

And I’d argue that ‘vegan’ is a bit nuanced.

Going back to the definition: what is practical and possible for you, might be different than me!

There’s really no justice or compassion comparing how ‘vegan’ you are compared to someone else.

I think most of us hold vegan values of anti-oppression to non human animals (the root)!

Why Go Vegan?

There are a variety of reasons for going vegan.

According to a article about Veganuary 2023 from Veganuary.com , 40% of participants doing Veganary said animals were their primary motivation for trying vegan. Personal health, and environment motivations followed(1).

Lets go into more detail about what these motivations could be about.

1. For the Animals

This reason is a foundational one for ethical vegans.

All animals raised for products, consumption, or secretions (ie: eggs, dairy), undergo suffering. Yes, even those claiming to be cage free, organic, or humanely sourced!

And a vegan diet is the diet that reduces animal suffering the most.

Perhaps you don’t have a dog companion, or the idea of visiting an animal sanctuary doesn’t sound fun to to you.

These are not requirements!

And in all honesty, I’m not I’m not exactly thrilled about the idea of having a pet despite my daughter really wanting one…

The only thing you need is the desire to reduce unnecessary suffering.

In the words of Jeremey Bentham: “The question is not, Can they reason? nor, Can they talk? but, Can they suffer?”

Going vegan for the animals is just another extension of compassion in an anti-oppressive, body liberating movement for animals.

2. For the Environment

Being vegan has a tremendous impact on the environment. Both from diet and non diet vegan lifestyle factors (it’s not necessarily eco friendly to make that fur coat!)

There is only so much we can and cannot do based on the financial resources and the power available to us.

However, unlike many other financially expensive choices, choosing a plant based diet alone can be a cost effective and eco friendly intervention.

How big? Well, one popular 2018 study published in the Science suggests that moving to a diet that excludes animal products could reduce land use by 76% and green house gas emissions by 49% (2)!

And it’s not just the whole food plant based foods that are better for the environment!

One recent 2023 study suggests that even when processed plant based ‘meats’ and plant based milks are included in vegan diet, it’s likely that GHG emissions are reduced when compared to pescatarian and no red meat diets (3).

Some vegans also see the environmental reasons as as having a broader social justice benefit:

A reduction in the global burden of world hunger.

Numerous studies suggest plant based diets (including vegan diets) are typically more eco friendly.

With this concept in mind-theoretically, if more people went vegan, there would be more water and land to grow food for hungry people.

Of course choosing to be vegan will not eradicate complex issues such as world hunger, and those affected by climate change.

And while the best diet for the environment depends on what the country has available in their food supply country, in the Untied States, it’s generally accepted that the more plants and less animal products consumed, the better the health of the planet.

3. For Your Health (Maybe)

Why is this reason controversial? Two reasons:

1. Veganism is more than a diet, and
2. a vegan diet can be as unhealthy or healthy as you make it

The Academy of Nutrition and Dietetics position paper on Vegetarian Dietary Patterns for adults states: “It is the position of the Academy of Nutrition and Dietetics that, in adults, appropriately planned vegetarian and vegan dietary patterns can be nutritionally adequate and can offer long-term health benefits such as improving several health outcomes associated with cardiometabolic diseases .”(4)

And, it suggests that some of the health benefits may lie in a well planned vegan diet that emphasizes whole foods like fruits, veggies, legumes, nuts, seeds, whole grains and healthy unsaturated oils (ex: like those derived from olives, and flaxseeds).

Along with a consistent source of vitamin B12 and other supplements as warranted, it’s easy to see that not every vegan diet would be considered “healthy.”

After all, it is possible to be vegan and only consume Oreos (FYI: this is not a recommendation)!

Ethical vegans may or may not be concerned about the health aspects of a vegan diet.

They might just avoid animal products for any of the other reasons listed above.

Sense veganism is more than a diet, and some vegans may not consume a healthy vegan diet, using health as a primarily motivation can be a slippery slope.

Another argument is that not eating eating animals lessens the use of animals, which might reduce disease in them.

Diseases in herds of animals raised as commodities can harbor zoonotic diseases.

It is theorized that if we “used” animals less, we might reduce the potential for animal derived diseases.

How Can I Start?

Talk to your doctor about this lifestyle change first.

Veganism is a philosophy inspiring a lifestyle change of reduced harm towards animals in some.

These guiding principles help vegans make decisions, from what to wear to what they consume.

Lets breakdown the lifestyle stuff into three categories and then go more depth with each of them.

The three categories of a vegan lifestyle include:

1. Vegan diet
2. Vegan Product Sifts
3. Activities That Vegans Tend to Avoid

1. Vegan Diet

Probably the best way to define it is by what foods are vegan, and what classic food and do not eat.

Vegan Food

Any food that exlcudes animals including whole:

• fruits
• vegetables
• grains
• nuts
• seeds
• legumes
• seed, vegetable and tropical oils
• Any other food without animals, such as vegan cereal, plant based ‘milk’, etc.

‘Foods’ Vegans Avoid

• Dairy
• Meat
• Fish
• Eggs
• Honey
• Any food that includes body parts or secretions of animals (ie: whey in chocolate, butter in bread, etc.)

To sum it all up: A vegan diet is one that avoids animal products, regardless of whether it is the main ingredient or not.

In essence, a vegan diet is not merely a plant based diet.

It’s a fully plant-based diet. 

Some Nutrients to Keep On your Radar with a Vegan Diet

Now that you know a vegan diet can be a healthy, lets discuss some things related to the “appropriately planned” part.

It is possible to meet nutrient needs on a vegan diet. However, this can be a learning curve.

So much nutrition information focuses on animal products (at least in the US).

Hopefully you feel more confident after reading through this guide!

Vitamin B12

• RDA (Recommended Dietary Allowance): 2.4 micrograms per day (for Non Pregnant/ Non lactating Adults, 19 years and older)(5).

The only food sources that already contain vitamin B12 are animal products (and even they may have been supplemented with the nutrient).

So, it is imperative that vegans consume a reliable source (typically a supplement as a convenient way) since they avoid animal products.

Not getting enough vitamin B12 is spells ill for health. For example, you could develop anemia and neurological problems from a deficiency (5). Aka- things nobody wants!

Vitamin B12 supplements and vegan friendly vitamin B12 fortified foods are available.

But you may not want to rely on B12 fortified vegan product alone, as attention to timing is important (intake needs to be spaced out), and you may have a more difficult time sticking it it consistently.

And, certain groups of vegans and vegetarians may have an even higher risk of vitamin B12 deficiency (6).

Luckily vitamin B12 supplements are easy to find and can be inexpensive!

The absorption process is complex , and there are a variety of health conditions, medications, and even life stages that can increase ones need for this nutrient. So its important to talk to your doctor about the form and dose of vitamin B12 that is appropriate for you.

Veganhealth.org has a chart about vitamin B12 that can be used as a talking point with your doctor.

Protein

One, if not THE most frequent question you may get as a new vegan is: “where do you get your protein?”

Keep these tips in mind for getting protein on a vegan diet:

1. Make sure you are eating enough in general. A Registered Dietitian can help you determine how much calories, and macronutrients you should aim for.
   
2. Eat a variety of plant based foods that contain a decent amount of protein: These include legumes, (ex: beans, lentils, soy), nuts and seeds, and whole grains like oatmeal. Consider including legumes in each meal, as they are rich in lysine – an essential amino acid that can be under looked in vegan diets if legumes aren’t included.
   
   Avoid vegan diets that limit food groups, such as the fruitarian diet- a diet that only includes fruit.
   
3. Know your protein needs:
   
   While the RDA states adults need 0.8 mg protein/kilogram body weight (1 kilogram = 2.2 pounds), some experts recommend more than this for vegans, such as at least 0.9 grams of protein per kilogram of body weight per day to take in account the reduced digestibility of plant proteins.
   
   FYI: Medical conditions, activity, and a bunch other factors can alter protein requirements. Talk to your doctor about how much protein you need.

Iron

RDA For Iron:

• Men (aged 19 to 50 years old): 8 milligrams (mg) per day.
• Females (aged 19 to 50 years old, non pregnant/non lactating): 18 mg per day(7).

Iron is so important for the formation of red blood cells, the transfer of oxygen, and many other functions.

Some folks may have a harder time getting enough for a variety of reasons including, heavy mensuration, iron deficiency, and lots of physical activity.

The iron in plant proteins (non heme iron) is not as easily absorbed as iron in meat (heme iron).

Here’s a few things to keep in mind about iron for vegans:

• Get familiar with plant based sources that contain a decent amount of iron! They include tofu, beans, chickpeas, lentils, etc.
• Adding vitamin C rich foods (this study used 25 milligrams of ascorbic acid. Example: there are about 56 milligrams of vitamin C, total ascorbic acid in approx 100 grams of raw strawberries) with your plant based iron containing foods.
• Cook your grains and legumes well (reduce phytates (iron absorption inhibitors)).
• For tea or coffee drinker you should consume it about an hour or two after an iron rich meal(8). This is because a substance called tannins in tea/coffee can inhibit iron absorption.
• If you have any concerns about your iron status, talk to your doctor.

Iodine

• RDA for Iodine: 150 mcg per day for non pregnant/non lactating adults aged 19 years and older (9).

Iodine, is an essential mineral that is necessary for proper functioning of your thyroid gland, a gland that is important for metabolism(9).

But consuming too much or two little iodine could cause an over active or slow metabolism and other problems.

Vegans avoid consume dairy or fish (common sources of iodine). But iodine can be obtained from certain vegan friendly sources, like iodized salt (always double check the label), bread made with potassium iodate or calcium iodate (10) and variable amounts are found in sea vegetables, like nori, seaweed flakes.   

However, since many of us are watching our sodium intake, and seaweed may not be the most available or inexpensive product in the US, you may be wondering if you should supplement. This is a good question to talk to your doctor about.

Calcium

• RDA for Calcium: 1000 mg per day for adults aged 19 to 50 years old(11).

Going vegan means giving avoiding dairy, which often raises the question:

“Where am I going to get calcium for bone health?”

Luckily, dairy products aren’t the only source of calcium. A fully plant based lifestyle can provide this essential mineral!

It’s super important to understand what calcium rich sources are available. A 2022 systematic review and meta-analysis suggests some vegans may not be getting enough calcium to meet the RDA (12).

But that doesn’t have to be you!

Make sure you know how to include calcium strong vegan foods in your diet, and talk to your doctor if you have concerns or need more guidance.

Examples of plant based foods (including fortified foods) that contain decent amounts of calcium include:

• Calcium set tofu
• Calcium fortified plant based milks
• Low Oxalate Green Vegetables (examples include: broccoli, kale, Chinese cabbage, bok choy) (of note- Phytates may reduce some calcium absorption).

Before you stock your fridge with tofu though, let me give you a few more bonus tips:

1. Certain greens such like spinach contain oxalic acid, which binds much of the calcium. Don’t count on them to contribute a significant amount of calcium in your diet.
2. Some vegan “milks” are not fortified (seems a bit counterintuitive right?) So if you want to replace your cows milk with plant based milk, make sure you read the label.

Vitamin D

• RDA For Vitamin D: 15 micrograms (600 International Units) per day for adults aged 19 to 50 years old (13).

Vitamin D is important for calcium absorption, maintaining bones, muscle function, and the immune system (12).

Some research suggests that vegans and vegetarians fall short on the vitamin D as compared to those who consume fish meat (13).

But Vitamin D deficiency is not exclusive to vegans!

While vitamin D in food does come from animal-based products, like fish, it is also known as the ‘sunshine vitamin.’

That’s because it is possible to get vitamin D from the sun.

However, getting too much sun can increase the risk of skin cancer.

Also, depending on how much time you spend outside, where you live, or how dark or light your skin is, your absorption can vary.

There are vegan sources of vitamin D, such UV treated mushrooms, fortified vegan vitamin D in some breakfast cereals and orange juice, nut or soymilks, but many of us probably aren’t eating enough of these foods to get all the  vitamin D we need.  

So talk to your doctor about getting your levels checked and whether supplementation is right for you.

Zinc

RDA for Zinc:

• Men (19+ years old): 11 milligrams (mg) per day.
• Female (19+ years old, non pregnant/ non lactating) 8 mg per day(14).

The underdog essential mineral you may want to pay closer attention to for immune health is: zinc!

Meat is rich in this nutrient, and may have been the primary source of zinc in your pre-vegan diet.

So what options do vegans have for zinc?

So many! Plant powered sources include (not a comprehensive list):

• Oats
• Soy
• Beans
• Nuts
• Seeds

Just make sure you don’t rely on fruit and salad greens to meet your zinc requirements. These are nutrient dense foods, but not zinc rich foods.

Like iron, phytates (a substance naturally found in plants) can inhibit zinc absorption(15).

Here’s a couple things that might enhance zinc absorption:

• Soak legumes thoroughly.
• Sprouted grain foods might have better zinc absorption (16).

ALA (An Essential Omega-3 Fatty Acid)

AI (Adequate Intake) for ALA:

• Men (aged 19+ years): 1.6 grams per day.
• Females (aged 19+ years – non pregnant/non lactating): 1.1 grams per day (17).

ALA (Alpha-linolenic acid) is an a essential omega 3 fatty acid. These fats make up a parts of our cell membranes. If we don’t get enough ALA, we might experience a variety of symptoms, including skin and hair problems(17)(18).

ALA can be exclusively obtained from plants.

Especially concentrated sources include (not a comprehensive list):

• ground flaxseed
• chia seeds
• walnuts

ALAs can be easily forgotten, so keep them in mind at meals and/or snacks.

But what about DHA (that Omega-3 that get’s alot of press these days?)

Other Nutrients to Have on Your Radar

Choline

AI For Choline:

• Men (aged 19 years and older): 550 milligrams (mg) per day.
• Females (aged 19 years and older, non pregnant/non lactating): 425 mg per day(19) .

Choline is one of the more recently discovered nutrients, and as such, we are still learning about it!

We do know that it is a essential nutrient with complex functions in the body, such as cell membrane signaling(20).

One study suggests that most Americans do not meet the AI(21). And this nutrient can be a bit more tricky to meet the AI on a vegan diet without planning.

Examples vegan foods that are more rich in choline include:

• Soy (tofu, soy milk, , etc)
• Potatoes
• Quinoa
• Beans
• Lentils

Don’t Forget Your Red/Orange Vegetables:

Find out why in our article Vegans: Vitamin A Needs to be on Your Radar!

Hint: it has to do with beta carotene (aka a precursor to vitamin A – the essential vitamin some of us may not be getting or absorbing enough of)!

Meal Panning

If you are saying cool, but how do I actually go about shopping on a vegan meal plan?

I got you!

In this Vegan Grocery Shopping article. I walk you aisle through aisle (pun intended), while keeping variety and nutrients in mind (key!)

If you have kids, I would strongly suggest you consider seeing a Registered Dietitian that specializes in vegan diets for children.

Karla Moreno-Bryce, MDA, RD, LD is an expert in vegan nutrition for kids.

Will I Need Any Supplements?

Vegans need to ensure they get a consistent and reliable source of vitamin B12. So talk to your doctor about supplementation.

As mentioned before, there are several other nutrients like vitamin D and iodine that may be tricky to get enough of as well – so put those on your list of topics with your doctor!

2. Vegan Products

Vegans try to avoid products that contain parts of an animal (such as leather).

Many also avoid products that have been tested on animal (ex: non vegan hair products, makeup, etc).

While some products have vegan labels, many do not.

Vegan products can also be difficult to find!

Again, what one can practically avoid will look different for everyone.

Not everyone has the same accessibility and that’s one reason why we can’t judge another for not completely avoiding all animal products.

In fact, is no such thing as completely avoiding animal products. It’s pretty much impossible.

Personally, I just try to think about the things that I really don’t need for my health and if I want them, can they be vegan?

Story time: I learned that lots of waxes contain beeswax!

So I get my eyebrows waxed with a sugar wax now – simple!

It’s something that I don’t need, but if I want it, I can choose a vegan option.

3. Activities That Vegans Tend to Avoid

Many vegans don’t support activities that exploit animals, such as:

• Circuses
• Zoos
• Aquariums
• Hunting
• Pet Farms
• Horseback Racing
• Any kind of animal fighting/betting

I know it can be hard to not partake in these activities when all your friends want to!

Perhaps you could suggest an alternative, such as going to a animal sanctuary instead of a zoo.

As a vegan, I also feel good in knowing that sometimes sitting out a zoo trip means having a conversation about how animals are used for our entertainment.

It gives folks something to think about (which is a great start)!

5 Tips For Going Vegan For Beginners

Now that you are equipped with so much knowledge, I hope you are feeling more confident about starting a vegan lifestyle.

But before you go, I want leave you with a few more tips!

1. Variety is key! Consuming a variety of fruits, vegetables, grains, legumes, and healthy fats should help you get closer to your nutrient targets. So eat a rainbow of colors (really though, this is a general recommendation for any healthy diet).
   
   But if you are saying, yah, but I need some guidance to make sure I am hitting those targets!
   
   I. Hear. You. When you are starting a vegan diet (really, any new diet!) sometimes, we think we are getting enough nutrition, when really, we might be falling short on some nutrients. That’s why I recommend seeing a Registered Dietitian who is familiar with vegan diets.
   
2. If you think you hate a bean, try a new recipe: Have you always said you hate broccoli, Brussel sprouts? Fill in the blank here?
   Personal story time: I was not always a fan of avocados. In fact, when I went out to eat with my boyfriend in college, I would take all the avocado out of my salad and give it to him!
   
   But later, I discovered a tasty way to make guacamole, and learned about avocado ice cream. Guess what? For what ever reason, I don’t mind avocado on my salad anymore! My college self would be shocked.
   
   The same thing might be true for you. The internet is full of tasty vegan recipes. Experiment, have fun, and be sure to jot down the ones you love so you can have them again (super important!)
   
3. Take Your Supplements: No explanation needed. Talk to your doctor about an appropriate supplement regimen for you. Luckily, if you made it to the end of this post, you have an idea about some of those nutrients you may want to discus (hint: many vegans will want to discuss a vitamin B12 supplement at least)!
   
4. Don’t Forget Your Snacks!: Ok, so this goes for anyone (vegan or not). But if you are trying to avoid something like animals for food, than don’t forget to have some snacks on hand in case you need them to tide you over to that full meal! Here’s some ideas for tasty vegan snacks!
   
5. This is a Lifestyle Change: If you have read this thoroughly, I am going to assume that you decided make this lifestyle change based on something outside of yourself. Perhaps you want to embrace the vegan philosophy.
   
   Whatever your reason, never forget it! Remember: most of the world does not follow a vegan diet. This means, you may encounter challenges when you go out to eat with friends, travel, or are pressured to eat your moms classic meat based recipes. This makes it so important to find a community that has like minded values.
   
   Know that no one is perfect. There is no vegan police going around and monitoring you. You are your worst critique, and tomorrow is a new day.
   
   Perhaps you chose to be a vegan as an extension of compassion to non human animals, but don’t forget to embrace that same compassion for yourself.
   
   Lastly, keep in mind that what’s practical for you might not be for someone else. Whether it be for accessibility or financial reasons. That doesn’t mean they care any less about the issues you care about!
