The Core Term: Vegetarian
The most straightforward answer to the question "What is a person called who only eats vegetables?" is a vegetarian. The term vegetarian refers to someone who abstains from eating meat, poultry, or seafood. However, the modern definition is more nuanced, as there are different types of vegetarians based on what animal products, if any, they choose to consume besides vegetables. For example, some may eat dairy and eggs, while others strictly avoid all animal-derived products.
Expanding on the term 'vegetarian'
While the simple term 'vegetarian' covers anyone who avoids animal flesh, the specific name for a person who literally only eats vegetables and no other food types (including grains, fruits, legumes, etc.) is not a common classification and is often referred to simply as a raw food diet or, more specifically, a fruitarian if only fruits are consumed. In practice, a standard vegetarian diet is more varied and includes a wider range of plant-based foods to ensure proper nutrition.
Different Types of Plant-Focused Diets
To understand a person's dietary choices fully, it is helpful to know the distinctions between the different labels. The following variations exist under the broad umbrella of plant-focused eating, clarifying what is and is not included beyond just vegetables.
Exploring the various labels
- Lacto-ovo vegetarian: Excludes meat, poultry, and fish, but includes dairy products (like milk, cheese) and eggs. This is one of the most common forms of vegetarianism.
- Lacto-vegetarian: Excludes meat, poultry, fish, and eggs, but includes dairy products. This is common in many cultures, such as in India, where dairy is a staple but eggs are avoided.
- Ovo-vegetarian: Excludes meat, poultry, fish, and dairy products, but includes eggs.
- Vegan: Excludes all animal-derived products completely. This includes meat, poultry, fish, dairy, eggs, and often honey or other animal by-products. Vegans typically extend this philosophy beyond diet to other areas of life, such as avoiding leather or wool.
- Flexitarian or Semi-vegetarian: A primarily plant-based diet that occasionally includes meat, poultry, or fish. This is sometimes referred to as a "part-time vegetarian" diet.
- Pescatarian: Excludes all meat and poultry but includes fish and other seafood. It typically also includes eggs and dairy. Pescetarianism is not strictly vegetarian, but is considered a plant-focused diet.
Comparison of different diets
To highlight the key differences, here is a comparison table outlining what is permitted in each diet.
| Diet Type | Meat (Beef, Pork) | Poultry (Chicken, Turkey) | Fish/Seafood | Dairy Products | Eggs | Animal By-products (Honey, Gelatin) |
|---|---|---|---|---|---|---|
| Lacto-Ovo Vegetarian | No | No | No | Yes | Yes | Sometimes (based on personal preference) |
| Lacto-Vegetarian | No | No | No | Yes | No | Sometimes (based on personal preference) |
| Ovo-Vegetarian | No | No | No | No | Yes | Sometimes (based on personal preference) |
| Vegan | No | No | No | No | No | No |
| Flexitarian | Sometimes | Sometimes | Sometimes | Yes | Yes | Sometimes |
| Pescatarian | No | No | Yes | Yes | Yes | Sometimes |
Motivations for a Plant-Based Lifestyle
People adopt a plant-based diet for a variety of reasons, often driven by a combination of health, ethical, and environmental considerations.
Health, ethical, and environmental reasons
- Health: Plant-based diets are often lower in saturated fat and cholesterol and higher in dietary fiber, vitamins, and antioxidants. Studies have linked vegetarian diets to a lower risk of chronic diseases such as heart disease, type 2 diabetes, and certain cancers.
- Ethical: Many choose vegetarianism out of respect for animal life and to oppose factory farming practices, which are often considered inhumane. Ethical vegans, in particular, oppose the exploitation of animals for any purpose.
- Environmental: The environmental impact of meat production, including greenhouse gas emissions, land use, and water consumption, is a major concern. Switching to a plant-based diet can significantly reduce one's carbon footprint and overall environmental impact.
Nutritional Considerations and Potential Risks
While a well-planned vegetarian or vegan diet can be very healthy, careful attention to nutrition is essential to avoid potential deficiencies, particularly for stricter diets.
Getting enough essential nutrients
Certain nutrients commonly found in animal products require conscious effort to obtain from plant-based sources. These include:
- Protein: Plant-based protein sources like legumes (beans, lentils), soy products (tofu, tempeh), nuts, and seeds can provide ample protein, but variety is key.
- Iron: The iron in plant foods (non-heme iron) is not as readily absorbed as the iron in meat. Pairing iron-rich plants like spinach and lentils with vitamin C-rich foods (e.g., bell peppers, citrus) can boost absorption.
- Vitamin B12: This vitamin is found almost exclusively in animal products. Vegans and many vegetarians must rely on fortified foods (plant milks, cereals) or supplements to meet their needs.
- Calcium and Vitamin D: While found in dairy, non-dairy sources like fortified plant milks, tofu, and leafy greens are available for those who avoid dairy.
- Omega-3 Fatty Acids: Important fatty acids like EPA and DHA are typically found in fish. Vegetarian sources include flaxseeds, chia seeds, and walnuts, but some may consider algal oil supplements.
How to Get Started with a Vegetarian Diet
Transitioning to a vegetarian diet can be a smooth process with the right approach. Here are some practical tips to help you get started:
- Start slowly: Begin by incorporating one or two meat-free days into your week. This can help you adapt to new flavors and meal ideas without feeling overwhelmed.
- Explore new recipes: Experiment with new cuisines that are traditionally rich in vegetarian dishes, such as Indian or Mexican. This can help keep your meals exciting and diverse.
- Focus on whole foods: Prioritize whole, minimally processed plant foods like fruits, vegetables, legumes, whole grains, nuts, and seeds. This ensures a higher nutrient intake compared to relying heavily on processed vegetarian alternatives.
- Plan your meals: Think about where you will get your protein, iron, and other key nutrients. Meal planning ensures a balanced diet and helps avoid grabbing unhealthy, convenient options.
- Learn to swap: Discover easy ingredient swaps. For example, use lentils instead of ground meat in a pasta sauce, or tofu in a stir-fry. Resources like the Academy of Nutrition and Dietetics provide excellent guidance.
- Consult a professional: If you are concerned about nutritional adequacy, especially if you plan to be a strict vegan, consider consulting a registered dietitian. They can help create a personalized plan to meet your nutritional needs.

Conclusion
In summary, a person who only eats vegetables and other plant-based items is a vegetarian. However, this term encompasses a range of dietary choices, from those who include dairy and eggs to strict vegans who avoid all animal products. A well-planned vegetarian diet can offer significant health benefits, but it requires thoughtful meal planning to ensure all essential nutrients are covered. By understanding the different types and nutritional aspects, individuals can make informed choices to suit their personal motivations, whether they are driven by health, ethical, or environmental concerns.
