Introduction: What to Know Before Starting a Vegan Diet

So, you’re thinking about giving the vegan diet a try—or maybe you’re just curious what it’s all about. Either way, you’re not alone. Millions of people are embracing plant-based living for their health, the planet, and ethical reasons. But what exactly does a vegan diet look like? Is it as healthy as it’s hyped up to be? And what should you watch out for if you’re new to this lifestyle?

In this friendly but fact-based guide, we’ll explore the essentials of the vegan diet: what it includes, its major benefits, common challenges, and tips for getting started the right way.

What Is a Vegan Diet?

At its core, a vegan diet excludes all animal products. That means no meat, dairy, eggs, or other animal-derived ingredients (like honey or gelatin). Instead, it focuses entirely on plant-based foods.

A typical vegan diet includes:

  • Fruits and vegetables
  • Whole grains (like oats, brown rice, quinoa)
  • Legumes (beans, lentils, chickpeas)
  • Nuts and seeds
  • Plant-based oils (olive, avocado, coconut)
  • Fortified non-dairy milks and meat alternatives (like tofu or tempeh)


It’s not just what you don’t eat—it’s about replacing those foods with wholesome, nourishing plant-based options.

Health Benefits of a Vegan Diet

The vegan diet can offer a variety of health benefits, especially when it’s well-planned and balanced. Here’s what the research says:

  1. Supports Heart Health

According to the American Heart Association, plant-based diets tend to be lower in saturated fat and cholesterol, which can help lower blood pressure and improve cholesterol levels.¹

  1. May Help with Weight Loss

Several studies have found that vegans tend to have lower body mass indexes (BMIs) than omnivores.² This may be due to higher fiber intake and less consumption of high-calorie, processed animal products.

  1. May Reduce the Risk of Chronic Diseases

A 2019 review in Nutrients found that plant-based diets were associated with a lower risk of type 2 diabetes, certain cancers, and cardiovascular diseases.³

  1. Promotes Digestive Health

Fiber-rich foods like legumes, fruits, and veggies are staples of the vegan diet. As a result, it supports better gut health and regular digestion.

Disadvantages or Challenges to Be Aware Of

That said, switching to a vegan diet isn’t without its challenges. While it can be incredibly healthy, it also comes with some nutritional gaps if not carefully planned.

  1. Risk of Nutrient Deficiencies

Vitamin B12, iron, zinc, calcium, and omega-3 fatty acids are harder to get on a vegan diet.⁴ You’ll need to rely on fortified foods or supplements to meet these needs.

  1. Social and Cultural Challenges

Let’s be real—it can be tough to eat vegan at social gatherings, restaurants, or family events. Planning ahead is key.

  1. Processed Vegan Foods Aren’t Always Healthy

Just because something is vegan doesn’t mean it’s good for you. Ultra-processed vegan snacks, fake meats, and sweets can still be high in sodium, sugar, and unhealthy fats.


Takeaway: A healthy vegan diet focuses on whole foods, not just anything labeled “plant-based.”

Other Reasons People Choose a Vegan Diet

Aside from health, many people go vegan for environmental and ethical reasons.

🌿 Environmental Impact

The vegan diet has a smaller carbon footprint compared to omnivorous diets. According to a 2018 study published in Science, avoiding animal products is one of the single biggest ways to reduce your environmental impact.⁵

🐮 Ethical Considerations

For many, going vegan is about animal welfare. Avoiding meat, dairy, and eggs aligns with a lifestyle that reduces harm to animals.

How to Get Started

If the vegan diet sounds like a good fit, here’s how to ease into it: 

1) Start Slow

You don’t have to go all-in overnight. Begin by making one meal a day fully plant-based. Or try “Meatless Mondays.”

2) Learn to Read Labels

Animal products can sneak into food under names like whey, casein, or gelatin. Familiarizing yourself with these terms can help.

3) Plan Balanced Meals

Use meal planning tools or apps to ensure you’re getting enough protein, iron, and B12.

4) Consider Supplementation

Speak to a healthcare professional about supplementing with B12, iron, and DHA/EPA omega-3s.
