Vegan Diet Retention Rates: How Many Stick With It?

Veganism is on the rise, with an estimated 79 million vegans worldwide as of 2021. This equates to just over 1% of the global population, with 2% of people in the US identifying as vegan and 3% following a vegan diet. However, the retention rate of those adopting a vegan lifestyle is unclear, with estimates ranging from 16% to 85%. While some sources claim that 84% of vegans and vegetarians abandon their diet, others argue that this figure is overstated and the true percentage is much lower. The controversy surrounding these statistics lies in the definition of veganism, the sample size and demographics of the studies, and the potential bias in the questions asked. Nonetheless, it is evident that veganism is gaining traction, with a growing number of people embracing plant-based diets and lifestyles.

Why people stay vegan

While it is challenging to estimate the global vegan population, there are approximately 79 million vegans worldwide. This number is expected to grow, with projections suggesting that by 2040, only 40% of the global population will continue eating meat.

There are several reasons why people choose to stay vegan. Here are some of the most common motivations:

Animal Welfare

The primary motivation for many vegans is animal welfare. People who choose veganism for this reason aim to exclude animal cruelty and exploitation from their lifestyle choices. Since 1970, the collective weight of free-living animals has reduced by 82%, and only 4% of cows and pigs worldwide are free-living. By choosing veganism, individuals can save animals from being used for food and contribute to reducing animal suffering.

Health Benefits

Some people adopt veganism due to the potential health benefits associated with a plant-based diet. A vegan diet is often linked to a reduced risk of certain diseases, including cardiovascular disease, type 2 diabetes, and certain types of cancer. It can also lead to lower blood pressure and cholesterol levels. However, it is important to note that a vegan diet may also be associated with adverse health outcomes, such as nervous, skeletal, and immune system impairments, and vitamin deficiencies, especially vitamin B12.

Environmental Concerns

Another reason people choose to stay vegan is to reduce their environmental impact. The meat and dairy industry is a significant contributor to global greenhouse gas emissions, with farming for animal products using a large amount of land and resources. A vegan diet can help reduce an individual's carbon footprint, preserve water resources, and contribute to a more sustainable future.

Personal Values and Ethics

For some individuals, veganism aligns with their personal values and ethical beliefs. This may include a belief in the inherent rights of animals to life and freedom, as well as a desire to reduce suffering and exploitation. Additionally, veganism can be a way to stand against inefficient food systems that disproportionately affect the poorest people globally.

Social and Cultural Influences

Veganism has gained mainstream popularity, and this social influence can be a factor in people choosing to stay vegan. The availability of vegan products, restaurants, and communities can provide support and make it easier for individuals to maintain a vegan lifestyle.

In conclusion, people choose to stay vegan for a variety of reasons, including animal welfare, health benefits, environmental concerns, personal values, and social influences. With the growing popularity of veganism, it is important to understand the motivations behind this lifestyle choice.

The health benefits of a vegan diet

A vegan diet, when planned and executed well, can be a very healthy choice. Research has shown that a vegan diet can help reduce the risk of heart disease, lower the chances of getting certain types of cancer, and manage diabetes.

Weight Loss

A vegan diet can help with weight loss. Observational studies suggest that vegans tend to have lower body mass indexes (BMIs) than non-vegans. In addition, some randomised controlled studies have reported that vegan diets are more effective for weight loss than other diets.

Heart Health

A well-planned vegan diet can include more whole grains, nuts, fruits, and vegetables than a standard Western diet. These foods are linked to a lower risk of heart disease. Observational studies comparing vegans with vegetarians and non-vegetarians report that vegans may benefit from up to a 75% lower risk of developing high blood pressure.

Diabetes

A vegan diet may also provide benefits for type 2 diabetes. Vegans tend to have lower blood sugar levels and higher insulin sensitivity and may have a lower risk of developing type 2 diabetes. A 2006 study reported that a vegan diet lowers blood sugar levels in people with diabetes more than the recommended diet from the American Diabetes Association (ADA).

Cancer

According to the World Health Organization, at least one-third of all cancers can be prevented by factors within your control, including diet. A 2017 study found that vegans may benefit from a 15% lower risk of developing cancer. Eating legumes regularly may reduce your risk of colorectal cancer, and eating more plant-based foods reduces your risk of several types of cancer, including stomach, lung, mouth, and throat cancers.

Arthritis

Some studies have reported that a vegan diet has positive effects on people with arthritis. A small study found that people with arthritis who switched to a whole food, plant-based vegan diet for six weeks reported higher energy levels and better general functioning than those who didn't change their diet.

Nutrients

A vegan diet can be richer in certain nutrients, including fibre, antioxidants, and beneficial plant compounds. They also appear to be richer in potassium, magnesium, folate, and vitamins A, C, and E. However, it is important to ensure a well-rounded diet, as poorly planned vegan diets may not provide sufficient amounts of vitamin B12, niacin, riboflavin, vitamin D, calcium, iodine, selenium, or zinc.

Protein

It is a common misconception that protein only comes from animal sources. Soy products (tofu, edamame), seitan, chickpeas, lentils, and nutritional yeast are all good sources of protein for vegans.

Vitamin B12

Vitamin B12 is essential, as a lack of it can make you feel tired and weak. It can be challenging for vegans to get enough vitamin B12, as it is not found in plants. Fortified cereals and rice, soy drinks, and supplements are good sources of vitamin B12.

Essential Fatty Acids

A lack of essential fatty acids has been linked to problems related to brain health, such as cognitive impairment and depression. Whole grains and leafy green vegetables (kale, spinach, collards) are good sources of essential fatty acids.

Iron

While red meat and egg yolks are the richest sources of iron, they are also high in cholesterol. Good plant sources of iron include black-eyed peas, tofu, and dried fruits.

Vitamin D

Vitamin D is important for regulating calcium and phosphate levels in the body, keeping bones, teeth, and muscles healthy. Sunlight exposure is a good source of vitamin D, as are fortified orange juice and soy products.

Calcium

Calcium is needed to maintain healthy bones and teeth. While non-vegans get most of their calcium from dairy, vegans can get it from green leafy vegetables (broccoli, cabbage, but not spinach), fortified unsweetened soya drinks, sesame seeds and tahini, bread, and dried fruit.

The environmental impact of veganism

Veganism has become increasingly popular in recent years, with more and more people adopting a vegan lifestyle. In 2021, there were an estimated 79 million vegans globally, which is just over one percent of the whole population. While veganism was initially propelled by ethical concerns about animal cruelty, it has also been driven by health, sustainability, and climate change concerns.

The meat and dairy industry is responsible for around 14.5% to 16.5% of global greenhouse gas emissions, a leading cause of climate change. Animal agriculture uses roughly 83% of global farmland but only provides about 18% of the world's calorie intake. A shift to veganism could therefore significantly reduce greenhouse gas emissions and land use.

A study of over 55,000 Britons found that vegan diets produce 75% less heat-trapping gas, generate 75% less water pollution, and use 75% less land than meat-rich diets. Vegan diets were also found to be higher in fibre and lower in cholesterol than omnivorous diets.

However, it is important to note that a vegan diet may not be suitable or accessible for everyone. Some individuals may struggle to meet their nutritional needs on a vegan diet, particularly those with certain health conditions or limited access to a variety of plant-based foods. Additionally, the environmental impact of veganism may be mitigated by factors such as the use of pesticides and soil degradation in crop production.

Overall, while veganism has the potential to significantly reduce environmental impacts, it is important to consider the limitations and ensure that any dietary changes are well-planned and informed by the latest research.

The rise of veganism

Veganism has seen a surge in popularity in recent years, with more people adopting a vegan lifestyle and diet every day. While it is difficult to estimate the global vegan population, there are approximately 79 million vegans worldwide, which is just over one percent of the world's population. This number is expected to grow, with projections suggesting that by 2040, only 40% of the global population will continue eating meat.

The Impact of the Rise of Veganism

Demographics of Vegans

It is worth noting that certain demographics are more likely to adopt a vegan lifestyle. Research suggests that most vegans are female, and a significant portion are millennials. Additionally, vegans tend to have a liberal political orientation and earn slightly less than the average American.

Challenges and Criticisms

While veganism offers many benefits, it is not without its challenges and criticisms. Some people view veganism as restrictive and difficult to maintain, especially when it comes to ensuring proper nutrition. There are also debates within the vegan community about the definition of veganism, with some advocating for a more inclusive approach that focuses on reduction rather than elimination of animal products.

The Future of Veganism

The future of veganism looks promising, with increasing consumer demand, corporate support, and environmental concerns driving the growth of plant-based alternatives. It is likely that veganism will continue to gain traction and become more mainstream, influencing not only dietary choices but also fashion, beauty, and other aspects of daily life.

The challenges of a vegan diet

A vegan diet can be challenging to adopt and maintain for several reasons. Here are some of the key challenges:

Nutritional deficiencies

One of the biggest challenges of a vegan diet is the risk of nutritional deficiencies. Vegans may struggle to get enough of certain essential nutrients, such as protein, calcium, omega-3 fatty acids, zinc, vitamin B12, and vitamin D. These nutrients are crucial for maintaining overall health and can be more difficult to obtain from plant-based sources. For example, vitamin B12 is primarily found in animal products, so vegans may need to rely on fortified foods or supplements to meet their needs.

Restricted food choices

Vegan diets are more restrictive than vegetarian or omnivorous diets, as they exclude all animal products. This restriction can make it challenging to plan balanced meals and ensure adequate nutrient intake. Vegans may need to be more mindful of their food choices and may have to put in more effort to ensure they are getting a variety of nutrients.

Social and practical challenges

Adopting a vegan diet can also present social and practical challenges. Eating out or attending social events where food is involved may become more complicated, as vegan options may not always be available. Additionally, vegan diets can require more time and effort in meal preparation, especially for those who are new to the diet or unfamiliar with plant-based cooking.

Lack of support

Maintaining a vegan diet can be challenging without a supportive community or network. Some people may face resistance or criticism from family, friends, or peers who do not understand or agree with their dietary choices. Finding a community of like-minded individuals, whether through local groups or online forums, can be crucial for staying motivated and committed to a vegan lifestyle.

Health conditions and life stages

For individuals with certain health conditions or those in specific life stages, a vegan diet may pose additional challenges. For example, pregnant or breastfeeding women need to ensure they are getting adequate nutrients for their own health and the development of their child. Similarly, ensuring proper nutrition for infants and children on a vegan diet requires careful planning and monitoring. In such cases, it is essential to consult a healthcare professional to ensure that nutritional needs are being met.

Limited options when dining out or travelling

While plant-based options are becoming more widely available, there are still limitations when it comes to dining out or travelling. Vegan options may be scarce or less varied in certain restaurants or locations, requiring more planning and preparation when eating outside the home.

Temptation and relapse

Finally, the challenge of temptation and the risk of relapse are real concerns for many vegans. With animal products being so prevalent and easily accessible, some individuals may struggle with staying committed to a vegan diet long-term. This challenge is particularly prominent in the early stages of adopting a vegan lifestyle, and having a supportive community can be instrumental in overcoming these hurdles.
