Study: Eating Vegan Would Save 8.1 Million Human Lives By 2050 – Here’s How

A new study by Oxford University has concluded that eating less meat and more fruit and vegetables will not only prevent several million deaths by 2050, it could cut planet-warming emissions substantially, and save billions of dollars annually in health care costs and climate change.

Understandably, you might be apprehensive about removing all animal products from your diet, but you can’t argue with the scientifically validated benefits – for health, the environment, and the animals – of doing so.

In 2010, the UN released a report revealing that a vegan diet is the best way to prevent global emissions from worsening climate change. And now, a study from Oxford University relays that by eating less meat and more fruit and vegetables, the world could prevent several million deaths per year by 2050, cut planet-warming emissions substantially, and save billions of dollars annually in healthcare costs and climate damage.

The study, which was published in the Proceedings of the National Academy of Sciences, is the first to estimate both the health and climate change impacts of a global move towards a more plant-based diet, reports Reuters

Said Marco Springmann, lead author of the Oxford Martin Program on the Future of Food:

“We do not expect everybody to become vegan, but climate change impacts of the food system will be hard to tackle and likely require more than just technological changes. Adopting healthier and more environmentally sustainable diets can be a large step in the right direction.”

Four different diets were taken into account by the Oxford University researchers: a ‘business as usual’ scenario; one that follows global guidelines including minimum amounts of fruits and vegetables and limits on red meat, sugar, and total calories; a vegetarian diet; and a vegan diet.

Profound observations were documented. The researchers determined that a diet in line with the global guidelines could avert 5.1 million deaths per year by 2050 while 8.1 million fewer human deaths would result in a world of vegans who do not consume animal products, including eggs and milk.

Regarding climate change, it was found that following dietary recommendations would cut food-relation emissions by 29 percent, adopting vegetarian diets would cut them by 63%, and following a vegan diet would cut emissions by 70%.

In addition, a savings of $700 billion to $1 trillion could be saved annually on healthcare, unpaid care and lost working days. The researchers state that the economic value of health improvements could be comparable with, and possibly larger than, the value of the prevented damage from climate change.

With reduced greenhouse gas emissions, the economic benefit could be as much as $570 billion.

Said Springman:

“The value of those benefits makes a strong case for increased public and private spending on programs aimed to achieve healthier and more environmentally sustainable diets.”



The researchers found that 3/4 of all benefits would occur in developing countries although the per capita impacts of dietary change would be greatest in developed nations, as affluent countries consume more meat and have higher rates of obesity.

Regional differences were also taken into account to determine the best interventions for food production and consumption in different areas. In East Asia, the West, and Latin America, for example, lowering meat consumption would be most beneficial. In South Asia and sub-Saharan Africa, increasing fruit and vegetable intake was found to be the largest factor in reducing deaths. Lowering calorie intake in Western Nations, the Eastern Mediterranean, and Latin America would result in a decrease in obesity, which would extend life.

To achieve a diet that sticks to common guidelines, there needs to be a 25% increase in the number of fruits and vegetables eaten globally and a 56% decrease in red meat. Humans would also do well to consume 15% fewer calories.

It’s quite easy to cut caloric intake by eating a predominantly plant-based diet, as whole foods are full of fiber, minerals, and an assortment of nutrients which satiate the body’s cravings and fill the stomach. In addition, when the body is no longer nutrient deficient from eating refined, processed foods, cravings tend to subside.

Now that Oxford University promotes a predominantly plant-based (vegan) diet for health and the planet, will you transition your diet to include more greens, vegetables, and fruit?

  1. You fail to mention availability of healthy fruits and vegetables. I live in a place where access to fresh fruits and vegetables is very low. Produce here is of the lowest quality. What little that is available is almost entirely GMO. Why would I spend money on slimy lettuce, sour tomatoes, and potatoes that fully half are rotten? My only options are meat, dairy, or processed garbage. Availability is a huge issue for many. If healthy options were available many more people would buy them. I know I would.

      • Glad I could brighten your day captain. Since you seem like such a caring person, would you mind paying the medical bills for people in my area? Dietary deficiencies cause a lot of health problems for many people everywhere. Pop your address up so we know where to send the bills. Thank you for your support.

  2. Did you check to see who paid for all these studies? Remember:follow the money.
    And, as far as I am concerned, anything from the UN is suspect. Not mention that a Vegan diet can be detrimental as well. No one diet is perfect.

  3. That is true! I think the government should focus on supply and accessibility of health fruits and vegetables across the country such as local support on farmers.
    Also, it has been proven that one of the main causes of global warming, drought and water shortage is due to raising livestock. These fast food mongols are trying to reach the demands of mostly meat-hungry society. If the people will boycott eating meat, the companies would have no option of raising and killing animals, not to mention how animals are treated inhumanly manner.

  4. Study neglects to take into account exactly how we are going to produce all these fruits and vegetables. Bees are needed to pollinate a majority of the produce we already eat, and they’re currently dying off at staggering rates due to pesticide-induced colony collapse disorder.

    • Consider the vast amount of land needed for animal agriculture (grazing). A reduction of 56% red meat would greatly increase the available land space to grow crops. Now consider the amount of land needed to grow crops to feed animals. It’s a staggering amount, and lots of soy, but the land use would be much more efficient. Growing the necessary amount of grains, fruits, and vegetables would be much easier than you think.
