Global Vegetarian Stats

There are 1.5 billion vegetarians worldwide, but only 75 million exclude meat by choice, according to an older but frequently cited January 2010 estimate from the Economic and Social Research Institute.

The other 1.4 billion are vegetarians out of necessity but would eat meat if they could afford it. Many vegetarians also avoid meat because it's part of their religion.


  • Up to 35.7% of India's population is vegetarian, making it the country with the most vegetarians, according to a May 2017 article in the ‌Journal of Medical Research and Innovation‌. That's because two of the largest religions in India encourage abstaining from specific meats.
    • 79% of India's population is Hindu and 14% is Muslim, according to the Pew Research Center. Hinduism encourages vegetarianism and followers traditionally avoid beef; followers of Islam traditionally avoid pork.
  • Here is the percentage of people who are vegetarian by country, according to the World Population Review:
    • India:‌ 24%
    • Mexico:‌ 19%
    • Brazil:‌ 14%
    • Finland:‌ 12%
    • Denmark:‌ 10%
    • Philippines:‌ 5%
    • China:‌ 5%
    • Russia:‌ 1%
  • People spent $28 billion globally on plant-based meat, seafood, milk, yogurt and cheese in 2022, according to the Good Food Institute (GFI) 's 2022 State of the Industry Report.
  • Global sales for plant-based milk, cheese and yogurt hit $21.6 billion — up 7% from 2021, per the 2022 GFI report.
  • Plant-based food is expected to make up 7.7% of the global protein market by 2030, according to Bloomberg Intelligence.

    • India
    • Sri Lanka
    • Italy
    • Lebanon
    • Indonesia
    • Taiwan
    • U.K.



Vegetarians in the U.S.

The percentage of people following a vegetarian diet in the United States is low compared to the percentage of people who regularly eat meat. Approximately 6 percent or 15.48 million adults in the U.S. are vegetarian, according to a 2022 YouGov poll published by the Vegetarian Resource Group.

This number may sound surprising, as so many plant-based alternatives have hit store shelves over the past several years. Plant-based milk, cheese and meat aren't just for vegans or vegetarians — many meat eaters are now experimenting with at least a small amount of plant-based eating.


  • Up to 65% of Americans ate plant-based meat alternatives in 2021, and 42% eat meat alternatives at least once a week, according to a June 2022 National Consumers League report.
  • Total U.S. retail plant-based food dollar sales reached $8 billion in 2022, while plant-based meat dollar sales decreased 1% from the previous year, per the GFI's 2022 State of the Industry Report.
  • An estimated 86% of households that purchased meat alternatives also purchased conventional meat in 2022, per the GFI's 2022 State of the Industry Report.
  • 39% of consumers choose plant-based options because they believe they're healthier than animal-based products.
  • About half of vegetarians are also vegans — approximately 7.74 million U.S. adults.


Vegetarians in the U.S. by Age

Worldwide, people eat meat from a variety of animals, including chicken, beef, pork and turkey. In some countries, camel, duck and horse meat are common protein sources, too.

Here's how much meat was produced worldwide in 2021, according to the 2021 stats from the FAO.

  • Chicken and poultry: 152.01 million tons
  • Pork: 132.69 million tons
  • Beef and buffalo: 84.6 million tons
  • Lamb and goat: 18.03 million tons

Environmental Effects of Eating Meat

Plant-based meat is often viewed as a more environmentally friendly option compared to the resources needed to produce meat. Efficient water use is one environmental concern. Here's the amount of water needed to produce one pound of meat and poultry, according to The Water Footprint of Food Guide:

  • 1,850 gallons of water per pound of beef
  • 720 gallons of water per pound of pork
  • 520 gallons of water per pound of chicken


Over 40 countries participate in the global initiative known as Meatless Monday to help reduce the environmental and health effects of meat-centered diets. This movement encourages people to reduce their meat intake one day a week or more. Here are some of the other environmental effects of eating meat, per the Meatless Monday initiative:

  • 14.5% of all global greenhouse gas emissions from human activities are produced from livestock production.
  • If meat was eliminated globally for one day per week, it could reduce diet-related global greenhouse gas emissions by an estimated 1.0 to 1.3 Gigaton (Gt) per year, which would be equivalent to taking 273 million cars off the road.

Global Accessibility of Meat

While some countries have low meat intake because of religious dietary restrictions, low-income nations have the lowest meat intake per person because of affordability, according to the World Atlas.

Meat is a high-cost item compared to many plant foods. Many poorer countries produce meat, but export it to other countries, making it too expensive for the people who live there.

Here are the countries where people eat the lowest amount of meat because of affordability and accessibility, and the average amount of meat eaten per year per person:

  • India:‌ 6.6 pounds of meat per person per year
  • Bangladesh:‌ 7.5 pounds of meat per person per year
  • Ethiopia:‌ 10 pounds of meat per person per year
  • Nigeria:‌ 13 pounds of meat per person per year
  • Tanzania:‌ 15.4 pounds of meat per person per year
  • Mozambique:‌ 16 pounds of meat per person per year
  • Ghana:‌ 19.9 pounds of meat per person per year
  • Indonesia:‌ 26.4 pounds of meat per person per year
  • Pakistan:‌ 27.9 pounds of meat per person per year
  • Haiti:‌ 29.9 pounds of meat per person per year

U.S. Meat Consumption Stats

  • This is how many times U.S. teens eat red and processed meat per day, per a May 2022 study in ‌Public Health‌.
    • Once a day: 58.4%
    • Twice a day: 29.8%
    • Three or more times a day: 13.2%
  • And the number of times adults eat red or processed meat per day:
    • Once a day: 52.2%
    • Twice a day: 33.9%
    • Three or more times a day: 13.9%

    • 70% of all beef food service purchases came from restaurants and bars in 2018, per the Cattleman's Beef Board and National Cattleman Beef Association.

Vegetarian Diet Health Statistics

The 2020-2025 Dietary Guidelines recommend the "Healthy Vegetarian Eating Pattern" as a nutritious diet for vegetarians. Following a proper vegetarian and vegan diet could lead to better health outcomes.

  • Plant-based eating patterns are linked to a decreased risk of kidney disease in people with type 2 diabetes and a decreased risk of death among people with chronic kidney disease, according to the American Diabetes Association. Compared to meat eaters, vegetarians eat less saturated fat and more:
    • Fiber
    • Vitamin C
    • Vitamin E
    • Magnesium
    • Potassium
    • Folic acid
    • Carotenoids
    • Flavonoids
  • The length of time a vegetarian diet is followed makes a difference in health outcomes, too, according to a March 2018 study in Nutrition and Diabetes.
    • "Consistent" adherence to a vegetarian diet was associated with a 35% lower risk of developing diabetes.
    • Those who adopted a vegetarian diet after being non-vegetarian had a 53% lower risk for developing diabetes than non-vegetarians.
  • The type of vegetarian diet followed makes a difference in the prevalence of diabetes, per an older May 2009 study in Diabetes Care, which analyzed the diets of over 60,000 adults. The prevalence of diabetes was:
    • 2.9% for vegans
    • 3.2% for lacto-ovo vegetarians
    • 4.8% for pescatarains
    • 6.1% for semi-vegetarians
    • 7.6% for non-vegetarians
  • Vegetarian diets are adequate for all stages of life and have been linked with the following health benefits, according to a December 2016 position statement in the ‌Journal of the Academy of Nutrition and Dietetics‌:
  • Researchers followed 12,168 middle-aged adults for 29 years and found plant-based diets protected many people from heart disease and heart-disease-related deaths compared to people who ate the most meat, per an August 2019 article in the Journal of the American Heart Association.
  • People following a plant-based diet had a 16% lower risk of heart disease.
    • People following a plant-based diet had a 31% to 32% lower risk of death from heart disease.
    • People following a plant-based diet had an 18% to 25% lower risk of death from all causes.

Health Risks of a Vegetarian Diet

It's no surprise diet affects mental and physical health. Some research suggests vegetarianism may be associated with a higher risk for mental health conditions and nutrient deficiencies compared to a meat-eating diet.

  • Vegetarians are twice as likely to experience depressive episodes than meat eaters, according to a January 2023 study in the Journal of Affective Disorders.
  • Up to 86% of vegetarian adults are deficient in vitamin B12
  • Up to 45% of vegetarian infants are deficient in vitamin B12
  • Up to 33% of vegetarian children are deficient in vitamin B12
  • Anywhere from 7% to 73% of vegetarians are iron deficient, according to a May 2017 study in the Annals of Nutrition and Metabolism.

Vegans and vegetarians have a higher risk of vitamin B12 and iron deficiency compared with people who eat meat, according to a December 2016 article in ‌Nutrients.

Iron from plant-based foods, known as non-heme iron, is not absorbed as well as iron from animal sources, according to a March 2021 article in ‌Biomolecules.‌ That means vegetarians need to eat twice the amount of iron to meet their needs.

Talk to your doctor or a registered dietitian before starting any new diet plan, but especially about how to plan a vegetarian or vegan diet that meets all your nutritional needs and dietary preferences. They may also recommend certain supplements if you are low in key nutrients on a vegetarian or vegan diet.
