Vegan diet review 2025

By Ann Peterson in 2025.

The vegan diet means you eat no animal products at all. That includes meat, fish, dairy, eggs, and even honey. Instead, you eat only plant-based foods. Fruits, vegetables, grains, beans, nuts, and seeds make up the bulk of a vegan diet.

Some people choose veganism because they care about animals. They don’t want to support industries that harm animals. Others pick it because they believe it’s better for the planet. Animal farming uses a lot of water, land, and energy. It also creates greenhouse gases that contribute to climate change.

Many people try the vegan diet for health reasons. Studies show that eating mostly plants can lower the risk of heart disease, diabetes, and some cancers. Vegans often have lower cholesterol and blood pressure than meat-eaters.

How Does the Vegan Diet Work?

The vegan diet works by cutting out all animal products and focusing on plants. Plants give you fiber, vitamins, minerals, and antioxidants. These nutrients help your body fight disease and keep you healthy.

You need to plan your meals well. That means making sure you get enough protein, iron, calcium, and vitamins like B12 and D. Some of these nutrients come mainly from animal foods, so vegans need to find plant-based sources or take supplements.

Vegans eat many different foods to stay balanced. Whole grains like rice, oats, and quinoa provide energy. Beans and lentils are great protein sources. Nuts and seeds add healthy fats. Fruits and vegetables offer vitamins and fiber.

Foods You Can Eat on a Vegan Diet

Fruits: Apples, bananas, berries, oranges, mangoes, and more.
Vegetables: Leafy greens like spinach and kale, carrots, broccoli, peppers.
Grains: Brown rice, oats, barley, wheat, quinoa, whole wheat bread.
Legumes: Beans, lentils, chickpeas, peas.
Nuts and Seeds: Almonds, walnuts, chia seeds, flaxseeds, sunflower seeds.
Plant-based Milks: Almond milk, soy milk, oat milk, rice milk.
Meat Alternatives: Tofu, tempeh, seitan, and other soy or wheat products.
Oils: Olive oil, coconut oil, avocado oil (in moderation).

Meat and fish.
Dairy products like milk, cheese, butter, yogurt.
Eggs.
Honey and any other animal-derived sweeteners.

Benefits of the Vegan Diet

The vegan diet offers many health benefits. It is naturally high in fiber, which helps digestion. Eating more fruits and vegetables means you get more vitamins and antioxidants that protect your body.

Many vegans have lower cholesterol and blood pressure. That lowers the risk of heart disease. A vegan diet is often lower in calories, so it can help with weight loss.

The vegan diet can also reduce your carbon footprint. It uses less water and land compared to diets heavy in meat and dairy. This can help slow down climate change.

Ethically, many vegans feel better knowing they do not support animal cruelty. They feel connected to their values by choosing food that respects animal life.

Challenges of the Vegan Diet

Switching to veganism can be hard at first. You need to learn new recipes and find plant-based alternatives. Some people miss the taste or texture of meat and dairy.

You must be careful to get all the nutrients your body needs. Vitamin B12 is found naturally only in animal products, so vegans need to take supplements or eat fortified foods.

Iron from plants is not absorbed as well as from meat, so you need to eat plenty of iron-rich foods and pair them with vitamin C to help absorption.

Eating out can be tricky. Not all restaurants offer vegan options, and some dishes may contain hidden animal ingredients like butter or broth.

Social events may also pose challenges if others don’t understand your diet or if there are few vegan choices.

Who Might Like the Vegan Diet?

The vegan diet fits well for people who:

Care deeply about animal rights.
Want to reduce their environmental impact.
Want to improve heart health and lose weight.
Enjoy cooking and experimenting with new plant-based foods.
Have ethical or religious reasons to avoid animal products.

It might not suit those who:

Prefer eating meat or dairy regularly.
Have difficulty planning balanced meals.
Are not willing to take supplements.
Need a diet with fewer restrictions.

What Does Science Say About the Vegan Diet?

Science shows many benefits to eating more plants and less animal food. Studies find vegans often have lower rates of heart disease, diabetes, and some cancers. They tend to live longer and stay healthier.

However, scientists also warn about risks of nutrient deficiencies if the diet is not planned well. Lack of B12 can cause anemia and nerve damage. Low calcium and vitamin D can hurt bone health.

Researchers recommend vegans eat a wide variety of foods and consider supplements for B12 and vitamin D. A balanced vegan diet can be very healthy but requires attention and care.
