The Pros And Cons Of Being A Vegetarian

The Pros And Cons Of Being A Vegetarian

The decision to become a vegetarian is a personal one that often involves ethical, environmental, and health considerations. Read on to find out about the advantages and disadvantages of being a vegetarian to help you make an informed decision about whether this dietary choice aligns with your values and goals.

Pros of Being a Vegetarian

One of the most significant advantages of a vegetarian diet is the potential for improved health. Vegetarians tend to have lower rates of heart disease, high blood pressure, type 2 diabetes, and certain types of cancer (particularly colorectal cancer). Their diets are typically rich in fibre, vitamins, minerals, and antioxidants found in fruits, vegetables, whole grains, nuts, and legumes.

Other pros include:

Weight Management

Vegetarians often find it easier to maintain a healthy weight or lose excess kilos. Their diets are lower in calories and unhealthy fats, making it more challenging to overconsume and gain weight. Plant-based diets are also associated with improved metabolism and fullness.


Lower Cholesterol Levels

A vegetarian diet is naturally low in saturated fats and cholesterol, as animal products are excluded. This can lead to lower levels of LDL (bad) cholesterol and a reduced risk of atherosclerosis and heart disease.


Ethical and Environmental Concerns

The meat industry is often associated with practices that raise ethical concerns, such as factory farming and animal cruelty. Choosing a vegetarian diet can align with one’s values of compassion and sustainability.

Cons of Being a Vegetarian

Nutritional Deficiencies

While a well-balanced vegetarian diet can be very nutritious, it may require careful planning to ensure all essential nutrients are obtained. Vegetarians need to pay attention to getting adequate protein, vitamin B12, iron, zinc, calcium, and omega-3 fatty acids, as some of these nutrients are more readily available in animal-based foods.


Limited Food Choices

Being a vegetarian may limit your food choices, especially when dining out or in social situations. You may find fewer menu options, and it may require extra effort to maintain a varied and balanced diet.


Social Challenges

It may be difficult to find suitable vegetarian options at gatherings or when dining with friends and family unfamiliar with vegetarian diets. This can lead to feelings of exclusion or having to compromise on your dietary choices.


Potential for Unhealthy Choices

A vegetarian diet can be unhealthy if it relies heavily on processed and high-sugar foods. Some vegetarians may opt for convenience foods that lack nutritional value, leading to weight gain and health issues.


Vitamin B12 Deficiency

Vitamin B12 is primarily found in animal-based foods, and a deficiency in this vitamin can lead to anaemia and neurological problems like memory loss. Vegetarians should consider B12 supplementation or enriched foods to ensure they meet their daily requirements.

Variations of Vegetarianism

There are various forms of vegetarian diets, each with its own set of restrictions:


This diet excludes meat, poultry, fish, and eggs, but includes dairy products.



Ovo-vegetarians exclude meat, poultry, fish, and dairy but consume eggs.


Lacto-ovo vegetarian

Lacto-ovo vegetarians exclude meat, poultry, and fish but include dairy products and eggs.



Vegans avoid all animal products, including meat, poultry, fish, dairy, eggs, and sometimes honey and gelatine.



Pescatarians exclude meat and poultry but include fish and other seafood.



Flexitarians are primarily vegetarian but occasionally consume meat or fish in small quantities.


Becoming a vegetarian is a personal choice that can benefit health, ethics, and the environment. However, it’s essential to approach this decision with awareness of the potential challenges and nutritional considerations. By carefully planning your diet to meet your needs and being mindful of the potential social and lifestyle adjustments, you can successfully embrace a vegetarian lifestyle that aligns with your values and promotes your well-being.
