Vegan Myths I Used to Believe (and Why I Don’t Anymore)

When I first went vegan, I believed almost everything I heard online. Looking back, many of those ideas were misleading or simply false. Here are the biggest myths I used to believe and what I understand about them now.

When I first transitioned to a vegan lifestyle back in 2014, I was open to almost anything I heard.

I wanted to do the right thing and move in the right direction, so I didn’t question much of the advice coming from early influencers in the space.

At that time, vegan content was growing fast online, and with it came a mix of useful guidance and completely unverified claims.

I was motivated, eager to learn, and unfortunately also very easy to influence.

Looking back, I can see how easy it is for new vegans to absorb ideas without filtering them properly.

Not because they are naive, but because they care and want to improve quickly.

Myth 1: A plant-based diet can cure anything

One of the biggest claims I came across was the idea that a whole food plant-based diet could cure almost any illness.

I remember following a very popular vegan couple who shared content saying that eating plant-based could reverse or cure conditions like cancer, depression, and even schizophrenia.

These are extremely serious claims, but they were presented as if they were absolute facts.

At the time, I wanted to believe it. I was dealing with my own mental health struggles and the idea that diet alone could fix everything sounded like hope in a simple form.

But reality is more complex.

While nutrition can absolutely support better health and improve quality of life, it is not a replacement for medical care, treatment, or professional support.

There is no miracle diet that fixes everything.

Myth 2: Vegans are morally superior

Another belief I slowly absorbed was the idea that being vegan automatically made someone morally better.

Yes, choosing not to support animal suffering is an ethical decision.

That part is clear. But extending that idea into overall moral superiority is where things become misleading.

Veganism is just one aspect of a person’s values, not the full picture of who they are.

Vegans can still hold harmful beliefs, treat others poorly, or act unethically in different areas of life.

And non-vegans can also be kind, compassionate, and deeply moral people in many ways.

At one point, I noticed I was even judging art and people differently just because I knew whether or not they followed a plant-based lifestyle. That bias felt subtle, but it was there.

Myth 3: Anger is the best form of activism

In my early years of advocacy, I believed that the louder and angrier I was, the more effective I would be.

I thought that shocking people or making them uncomfortable was the fastest way to create change.

My intention was awareness, but the result was often distance instead of understanding.

Over time, I realized that this approach was not helping me or the people around me. It made conversations harder, relationships more tense, and my own mindset heavier.

Discovering a more compassionate and calm style of communication changed everything.

It showed me that activism does not need to be aggressive to be meaningful.

What I learned from all of this

Looking back, the common thread in all these myths is not veganism itself, but how information spreads without being questioned.

Veganism is a powerful ethical and lifestyle choice, but it is not magic.

It does not make anyone invincible, superior, or automatically right in every discussion.

What matters most is staying grounded, thinking critically, and being willing to update your beliefs as you learn more.

You can be passionate without being extreme. You can care deeply without believing everything you hear.

And most importantly, you can choose who influences your thinking.

Final thoughts

Veganism is still something I believe in strongly. But it works best when it is treated with balance, realism, and humility.

Health is not guaranteed. Morality is not one-dimensional. Activism is not one-size-fits-all.

Speak up when it matters, stay open when you can, and keep learning along the way.

You got this.
