There is still a lot of controversy about vegan diets, especially when it comes to deciding if they are healthy or harmful. Many believe excluding all animal products from the meal plan is unhealthy, leading to nutritional deficiencies. In this article, I'll explain six science-backed health benefits of a vegan diet and provide the key to thriving on plants.

Health Organizations in Favor of Vegan Diets
More and more healthcare-related organizations and even the Canadian government speak out in favor of a plant-based diet:
- The British Dietetic Association has confirmed that ‘well-planned vegan diets can support healthy living in people of all ages’.
- The American Heart Association has stated that eating less meat can prevent or reverse chronic illnesses like heart disease or diabetes.
- The World Health Organization has classified processed meat as a potential cause of cancer.
- The Canadian government's new food guide 2019 generally recommends a shift in eating habits ‘towards more plant-based foods.’
- The Blue Zones demonstrate that the people with the highest (healthy) life expectancy around the world have a ‘plant slant. Beans, including fava, black, soy, and lentils, are the cornerstone of most centenarian diets.’
6 Health Benefits of a Vegan Diet
I guess there must be some evidence that eating plants is good for your health, or else these renowned associations and organizations would either remain silent on the subject or clearly speak against it.
I was curious to find this evidence and looked for scientific research backing the argument that people can thrive on a vegan diet.
I found it. Indeed, I found plenty of it and was astonished by the various diseases a diet focusing on plants can help prevent or alleviate.
So, what does the research say about vegan diets?
These are six science-backed areas where you can see health benefits following a vegan diet:
- Heart Disease
A diet rich in healthy, whole-grain, plant-based foods has been proven to reduce the risk of coronary diseases, as vegan meals tend to be low in saturated fats. Vegans tend to have lower blood pressure and levels of cholesterol. An identical twin study even showed that "a vegan diet can improve cardiovascular health in weeks." (1, 2, 3, 4, 5, 6, 7, 8) - Diabetes
Vegans have a lower risk of getting type 2 diabetes. Persons with type 2 diabetes switching to a vegan diet are proven to gain better glycemic control. (7, 9, 10, 11, 12, 13, 14, 15) - Cancer
Research shows that vegan diets offer protection against cancer, in particular, prostate, breast, and colon cancers. When it comes to breast cancer, many studies have proven a strong preventive effect of soy food. (7, 16, 17, 18, 19, 20, 36) - Osteoporosis
Most studies on the subject matter indicate that vegan diets are not better or worse when it comes to preventing osteoporosis. Still, there is also some evidence that a plant-based diet might be beneficial to bone health provided that the lifestyle allows for sufficient physical activity. (21, 22, 23, 24, 25) - Arthritis
There is some scientific evidence that vegan diets improve the symptoms of rheumatoid arthritis, especially if the diet is gluten-free. (26, 27, 28, 29, 30, 31) - Obesity
By nature, plant-based meals tend to be lower in fat and calories, thus promoting weight loss and making it easier to maintain a healthy weight. (6, 7, 9, 32, 33, 34, 35)
Vegan Diets can Maintain Health Long Term
As veganism has gained popularity in recent years, there is little research to prove that a plant-based diet can be healthy in the long run as well, for example, over many decades. Yet, the Blue Zones have shown that the world's longest-lived and healthiest people stick to a diet heavy on plants.
One of the most famous Blue Zone centenarians is Dr. Ellsworth Wareham, a retired cardiothoracic surgeon who lives in Loma Linda, USA. He has been living plant-based for more than 50 years, and he attributes his health and fitness to this very fact. You can watch the inspiring interview with Dr. Ellsworth Wareham, recorded when he was 98 years old.

What's the Catch?
You might wonder what the catch is hearing about all these health benefits of a vegan diet.
There must be one, right?
Right, there is one. To reap off these benefits, you must adhere to a diet full of whole grains, fruits, nuts, seeds, beans, and vegetables. The less refined the food you’re eating, the better. That is, it doesn’t suffice to take a regular Western diet and leave out the meat, the dairy, and the eggs. It’s also essential to stay away as much as you can from products high in refined sugar, chips, and all the other packaged ready-to-eat meals (but the occasional indulgence won’t hurt anyone). A vegan diet is most beneficial if it consists for the most of fresh or freshly prepared produce that’s organic, local, and in season. I guess this is a small price for staying healthy or alleviating symptoms of certain diseases.
Take-Home Message
There is plenty of scientific evidence already that a well-planned, healthful diet based on nutrient-rich whole plant foods is likely to keep you healthy in the long run and help you avoid the most common diseases of Western societies, such as obesity, cardiovascular disease, high blood pressure, or type 2 diabetes. No wonder public organizations started encouraging people to embrace a diet revolving around plants.
However, the Blue Zones show beautifully that having a “plant slant” on your plate is just one of many pillars needed to live a long, healthy, and happy life. Getting daily some physical activity, having a sense of purpose in life, spending time with your loved ones, and having a group of kindred people to socialize with, amongst others, are all factors contributing to your health, happiness, and longevity.
