Why are vegetarians allowed to eat eggs?

Many people are confused about what vegetarians can and cannot eat. While vegetarians avoid meat, poultry, and fish, eggs are considered a gray area. So why are most vegetarians allowed to eat eggs? There are a few key reasons.

Quick Answers

– Most vegetarians avoid meat and animals that are killed for food but eat dairy and eggs from animals that don’t require killing.

– Eggs are seen as a by-product – hens lay eggs naturally, whether they are fertilized or not.

– Some vegetarians only eat free-range or organic eggs from hens treated humanely.

– Vegetarians avoid meat because of moral reasons, health reasons, environmental reasons, or a combination. Eggs do not go against these rationales.

– There are different types of vegetarians (lacto-ovo, lacto, ovo, pescatarian) with different dietary restrictions regarding eggs and dairy.

Understanding Vegetarianism

Vegetarianism is defined as abstaining from the consumption of meat, poultry, and fish. However, there are several variations of vegetarian diets:

– Lacto-ovo vegetarians eat dairy products and eggs but avoid meat, poultry, and fish. This is the most common type of vegetarian diet.

– Lacto vegetarians eat dairy products but avoid eggs, meat, poultry, and fish.

– Ovo vegetarians eat eggs but avoid dairy products, meat, poultry, and fish.

– Pescatarians eat fish and seafood but avoid poultry and meat. They may also eat eggs and dairy products.

As you can see, the only vegetarian diets that completely eliminate eggs are the vegan and lacto vegetarian diets. For all other vegetarian types, eggs are fair game.

Why Do Vegetarians Avoid Meat?

Vegetarians choose to forgo meat consumption for various reasons:

– **Ethical reasons** – Not wanting to harm animals that are killed for food production. object to the cruelty involved in factory farming and slaughterhouses.

– **Health reasons** – Concerns over the antibiotics, hormones, and contaminants present in conventionally raised meats. Some studies have linked vegetarian diets with lower risk of heart disease, diabetes, cancer, and obesity.

– **Environmental reasons** – Meat production requires far more land, water, and resources compared to plant foods. It also contributes to air and water pollution.

– **Religious/spiritual reasons** – Some religions promote vegetarianism or non-violence towards animals.

Eggs are not implicated in the ethical, health, and environmental problems associated with meat production. Let’s explore why in more detail.

Why Eggs Are Considered Different Than Meat

Here are some key reasons why eggs are exempt from most vegetarian diets:

Eggs Don’t Require Killing Animals

Vegetarians who give up meat for ethical reasons are opposed to killing and slaughtering animals for food. The production of eggs does not require the death of an animal.

Hens naturally ovulate and lay eggs whether they have been fertilized or not. The hens are kept alive to continue producing eggs. Vegetarians who eat eggs rationalize that eating an unfertilized egg does not constitute taking a life.

Eggs Seen as By-Product of Hens

Eggs are considered more of a by-product or plant-based food, rather than animal flesh. Hens will lay eggs regardless of whether humans collect and eat them. The hens do not have to be slaughtered, unlike cows, pigs, and chickens raised for meat.

For this reason, many vegetarians view eating eggs as aligned with a cruelty-free, meatless diet. The hens are not killed and are generally able to live out their natural lives.

Free-Range and Organic Options

Another factor is that there are more humane options for egg production, such as free-range, pasture-raised, and organic eggs. Vegetarians may seek out these specialty eggs from hens that are able to freely roam outdoors.

The living conditions are drastically different than the cramped, confined cages found in conventional factory farms. So for vegetarians concerned about animal welfare, eggs from humanely raised hens are aligned with their ethics.

Environmental Impact Lower Than Meat

In terms of environmental impact, eggs are also considered a more sustainable food choice than meat:

– Hens efficiently convert vegetable feeds into a highly nutritious food source (eggs).

– Commercially raised hens for egg production generate lower greenhouse gas emissions compared to other types of animal agriculture.

– Egg production has a lower overall environmental footprint than meat in terms of land, water, and energy required per gram of protein.

For vegetarians motivated by reducing their eco-footprint, eggs are generally considered acceptable over lamb, beef, pork, etc.

Nutritional Profile of Eggs

Eggs also remain a part of vegetarian diets because they serve as an excellent source of protein, nutrients, and health benefits:

High-Quality Protein

– One large egg provides 6 grams of protein, including all 9 essential amino acids. The protein quality in eggs is very high and utilized efficiently by the body.

Important Nutrients

– Eggs are a good or excellent source of choline, selenium, vitamins A, B2, B5, B12, iron, and zinc.

Powerful Antioxidants

– Egg yolks contain the antioxidants lutein and zeaxanthin, which support eye health and reduce risk of eye diseases.

Health Benefits

– Studies show eggs support weight management, muscle strength, brain function, eye health, and more.

– The high nutrient density and versatitily of eggs makes them a simple way for vegetarians to meet their nutritional needs.

For vegetarians looking to avoid nutritional deficiencies, eggs offer a powerhouse of protein and micronutrients that are more difficult to obtain from plant foods alone.

Are There Any Arguments Against Eggs?

While the majority of vegetarians include eggs in their diet, there are some counter-arguments:

Male Chick Culling

– In commercial hatcheries, male chicks are killed right after hatching because they cannot lay eggs and are not suitable for meat production. This could be an ethical concern.

Poor Living Conditions

– Most hens are intensively confined in small cages with no access to outdoors. Some vegetarians avoid conventional eggs due to the poor welfare standards.

Environmental Impact

– Large factory farm egg production generates significant greenhouse gas emissions, manure, and nitrogen pollution. From that perspective, eggs may not be considered sustainable.

However, it is possible to find pasture-raised, free-range, or organic eggs where the animal welfare and sustainability concerns are minimized.

Ultimately eggs represent a gray area, and vegetarians have to weigh the pros and cons of eating eggs from an ethical framework.

Types of Vegetarians Who Avoid Eggs

There are some vegetarian diets where egg consumption is prohibited:

Lacto Vegetarians

Lacto vegetarians avoid all animal flesh and eggs but do consume dairy products. An example meal plan for a lacto vegetarian:

– Breakfast: Oatmeal with dairy milk, fruit, toast with nut butter
– Lunch: Grilled cheese sandwich and vegetable soup (with milk)
– Dinner: Cheese ravioli with marinara sauce, side salad (with cheese)


Vegans follow a strict plant-based diet avoiding all animal products including meat, eggs, and dairy. An example meal plan:

– Breakfast: Avocado toast, oatmeal with almond milk, banana
– Lunch: Lentil vegetable soup, side salad with vinaigrette
– Dinner: Veggie stir fry with tofu over rice

Some Religious Vegetarians

Certain religious sects like Jainism also avoid eggs to minimize harm and violence to living creatures as part of their core tenets.

In Summary

While eggs come from animals, the production does not require directly killing animals as is the case for meat production. Eggs are seen as more of a by-product, while the hens live out long, natural lives.

For these reasons, eggs are generally considered acceptable in most vegetarian diets. However, there are some objections related to industrial production practices. The killing of male chicks and poor living conditions for layer hens represent ethical issues that some vegetarians cite for avoiding eggs.

Overall eggs fall into a gray zone. Most vegetarians make room for eggs due to their high nutrient levels and lower ethical and environmental footprint compared to meat. But eggs are avoided by strict vegetarians like vegans and some religious groups seeking to minimize harm to animals.

Within the spectrum of vegetarian diets, there remains disagreement about egg consumption. Each vegetarian must weigh the arguments for and against eggs and make an individual choice according to their own moral framework.

Frequently Asked Questions

Are eggs considered vegetarian?

Yes, eggs are generally considered vegetarian, except for vegans and some religious vegetarian diets that exclude all animal products. The majority of vegetarians (lacto-ovo, pescatarian, etc.) do include eggs in their diet.

Do vegetarians eat eggs from the supermarket?

Many mainstream vegetarians do consume common supermarket eggs from factory farm hens. However, some vegetarians only eat free-range, organic, or local farm eggs where they can ensure the hens are raised humanely.

Why don’t vegans eat eggs?

Vegans avoid eggs because their diet eliminates all forms of animal exploitation. They object to commercial practices like killing male chicks, confined housing, forced molting, overbreeding hens, etc. that are unethical from an animal rights standpoint.

Are eggs healthier than meat?

Yes, eggs are a nutritious protein source packed with vitamins and minerals. Studies show eggs improve cholesterol profiles in most people. Red meat has higher risks of saturated fat, heart disease, cancer, and mortality according to large reviews.

Do vegetarians eat egg whites only?

Most vegetarians consume whole eggs. The egg yolk contains beneficial nutrients like choline, antioxidants, vitamins A, D, E, K. Removing the yolk significantly reduces the nutritional value. Whites alone are not as healthy or satisfying.

Can eggs be produced ethically?

There arearguments that small-scale, free-range egg production can be ethical if practices like grinding/suffocating male chicks are avoided. Some vegetarians seek out only these humanely produced eggs.


Eggs represent a unique food choice for vegetarians. While eggs come from animals, vegetarians generally find eating eggs more aligned with their diets compared to meat and other animal flesh. This is because hens can live well and lay eggs naturally without being killed.

However, large-scale commercial egg production involves practices that some vegetarians may object to on ethical grounds. There are pros and cons that each vegetarian has to evaluate for themselves when it comes to including eggs in their diet. With options like free-range and local eggs available, Vegetarians can adapt egg consumption to fit their own moral standards and principles.
