Vegans choose their diet, and lifestyle, for a number of reasons, including the desire to eat a healthier diet, for environmental concerns, and prevention of cruelty to animals. While there are commonly known pros and cons of going vegan, there are some lesser known pros and cons of following a vegan diet and lifestyle. 

Pros of going vegan 

Most sources that tout the pros of going vegan mention the healthy cardiovascular benefits, and lower risk of developing diabetes. Other pros likely leads some individuals to change their diet to that of a true vegan. Vegetarians include dairy, and eggs in their diet, while vegans exclude all meat products from their diet and lifestyle. 

One pro related to going vegan is the environmental benefits. Results of a study published by the Proceedings of the National Academy of Sciences (PNAS) indicates that eating a plant-based diet: 

  • Reduces pressure on land use 
  • Potentially reduces greenhouse gasses 
  • Possibly helps avoid the devastating consequences of climate change 
  • Likely prevents other negative environmental impacts

Another pro is the fact that in a study involving 840 participants, results show that when compared to individuals following one of several vegetarian diets, vegans fared better in reducing their risk of developing serious medical conditions. Vegan study participants had higher levels of compounds that reduce inflammation, higher biomarkers that prevent cancer and hypertension, higher levels of antioxidants, and Omega-3 fatty acids, compared to the other groups. 

Participants following the vegan diet, along with those following the vegetarian diets, provided urine, blood, and fat samples, explains Nina Parker, writing for the Atlanta Journal-Constitution (AJC). 

The BBC recently revealed the seriousness of eating a poor diet. A 17-year-old British teenager actually went blind after consuming a strict diet of a certain brand of potato chips (crisps), fries (chips), and white bread. Doctors attribute the blindness to his refusal to change his eating habits, which resulted in severe vitamin and mineral deficiencies, and malnutrition damage.

Cons of going vegan

While there are many pros associated with going vegan, there are some cons to adopting a vegan lifestyle. One example is that choline, most often present in animal foods, is a crucial nutrient likely lacking in a vegan diet. The nutrient is important in liver function, and in brain health, including during fetal development. 

Science Daily quotes Dr. Emma Derbyshire, who calls the potential choline deficiency associated with a vegan diet “concerning.” She suggests taking choline supplements.

There are other cons related to going vegan, including:

  • Vegans must adjust their diet gradually to minimize the possibility of developing gastrointestinal discomfort
  • Most vegans recognize the need to monitor their B12, Vitamin D, and iron levels 
  • Some vegans develop Orthorexic eating disorder, which occurs in people that take the idea of following a strict diet to the extreme, possibly leading to depression or anxiety related to the obsessive thoughts

There are outstanding benefits of going vegan, along with some cons. Following a vegan diet potentially helps you lose weight, and experience improved health.

Check with your physician before starting a vegan diet and lifestyle, particularly if you currently experience any medical condition.
