Do vegans live longer?
Plant-based lifestyles can drastically lower rates of some serious diseases
Vegan diets are becoming increasingly popular, with an estimated 2% of the UK population now cutting out meat and dairy products.
With champion athletes such as Novak Djokovic, Lewis Hamilton and Venus Williams swearing by their plant-based diets, the health benefits of going meat-free are becoming more widely publicised.
But can a vegan diet make you live longer? And if so, how?

What is a vegan diet?
For some, veganism is about more than what you eat. It 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”, said the Vegan Society.
A plant-based diet, which excludes animal foods such as meat and fish, dairy, eggs and honey, is part of a vegan lifestyle.
Do vegans live longer?
A 2013 study published in the JAMA Internal Medicine journal found that “vegans have a 9% lower risk of death from all causes compared with omnivores”, according to Live Science.
Another study found a 12% lower risk, but while research published by the American Journal of Clinical Nutrition agreed that a vegan diet can lower rates of certain chronic diseases, it did not find evidence that veganism led to a longer life.

Nevertheless, vegan diets have been linked to “the reduction of risk for multiple chronic health conditions associated with heart disease, type 2 diabetes, certain types of cancer, and obesity”, Brooke Jacob, a registered dietician, told Live Science.
While “it is not surprising” that vegans may live longer, “as following a vegan diet is linked to reduced occurrence of chronic disease… more research is needed to definitively conclude that vegans live longer than non-vegans”, she said.
What are the health benefits of going vegan?
Avoiding the saturated fat in meat can provide a health boost. Processed meat like ham, sausages, salami, bacon, smoked and canned meat have been classed as class-1 carcinogens by the World Health Organization, “the same classification as tobacco smoking, asbestos, and radioactive barium”, said Vegan Food and Living.
Dairy and eggs, which vegans don’t consume, are also high in saturated fat. Vegans and vegetarians “on average” tend to eat more “nutritious, whole plant-foods”, said the publication.
Indeed, said Live Science, healthy lifestyle habits such as “eating whole foods, exercising, drinking enough water… might be more prevalent in the vegan community”. Similarly, a study that found that vegetarians live up to six or nine years longer also discovered that vegetarians are also more likely to exercise, be married, smoke less and drink less alcohol, said Quartz.
But while vegan fast food options “might sound like a guilt-free alternative”, they are “often worse for your health than the meat equivalent”, warned William Park at the BBC. For example, salt is usually added to vegan fast foods to “give the same meaty, rewarding sensation that would otherwise be missing”, he said.
And the NHS advises that “if you do not plan your diet properly, you could miss out on essential nutrients, such as calcium, iron, vitamin B12, iodine and selenium”.
How can I eat a healthy vegan diet?
Veganuary suggests that new vegans focus on consuming enough protein, as well as calcium, iron, vitamin B12 and other minerals.
“If we choose wholefoods, legumes, nuts, fruits, spices, herbs and some of the 20,000 edible plants that exist in the world, we can experience an incredible improvement in our health while enjoying some wonderful flavours,” said the non-profit group.
And the NHS states that “you can get the nutrients you need from eating a varied and balanced vegan diet including fortified foods and supplements”.
