There are several types of vegetarian diets, and the best one for you depends on factors like nutritional quality, cost, and sustainability. A vegan diet is the most restrictive vegetarian diet, excluding all animal products, including meat, poultry, fish, eggs, and dairy. Lacto-ovo vegetarians, the most common type of vegetarian, eat dairy and eggs but no meat or fish. Other types of vegetarian diets include pescetarian, which includes fish but not meat, and flexitarian, which is mostly plant-based but includes small portions of meat and seafood.

Lacto-ovo vegetarians
There are several health benefits associated with a lacto-ovo vegetarian diet. Research suggests that it can improve heart health, support weight loss, and reduce the risk of certain cancers, type 2 diabetes, and gallstones. Lacto-ovo vegetarians have also been found to have lower cholesterol and saturated fat intake, contributing to a reduced risk of cardiovascular disease. Additionally, plant-based diets are typically high in fibre, which aids in weight management and improves blood sugar control.
People choose to adopt a lacto-ovo vegetarian diet for various reasons, including health, ethical, and environmental concerns. It provides a way to reduce animal product consumption without completely eliminating them, making it a popular choice for those transitioning to a more plant-based lifestyle.

Pescetarians
A pescetarian diet is a vegetarian diet that includes fish and seafood. The term "pescetarian" is a combination of the Italian word for fish, "pesce," and the word "vegetarian." The diet is sometimes referred to as "pesco-vegetarian."
Pescetarianism is a popular dietary choice, with approximately 3% of adults worldwide following this diet, according to research conducted from 2017 to 2018. It is more common among women than men and is particularly popular among young women in the United Kingdom. The popularity of pescetarianism has been increasing, with surveys showing a rise in the number of people adopting this diet in the mid-to-late 2010s.
Pescetarianism offers a balance between plant-based and animal-based foods. It is often chosen by individuals who want the health benefits of a largely vegetarian diet while still including seafood in their meals. Regular fish consumption and reduced red meat intake are associated with positive health outcomes. Additionally, seafood provides important nutrients such as omega-3 fatty acids, which are beneficial for heart and brain health.
Some historical contexts have also favoured pescetarian diets. For example, several orders of monks in medieval Europe restricted meat consumption for ascetic reasons but continued to eat fish. The "Hearers" of the ecclesiastical hierarchy of Manichaeism, for instance, consumed only fish, grain, and vegetables, believing that fish were pure and untainted by the impurities that polluted land animals.

Vegans
A vegan diet can have several health benefits. Research suggests that vegan diets can support weight loss and may help lower the risk of obesity and chronic diseases like type 2 diabetes, heart disease, and cancer. Additionally, vegans have lower rates of illness and death from some degenerative diseases. However, a vegan diet may be low in certain nutrients, such as vitamin B12, vitamin D, calcium, iron, and omega-3 fatty acids, which are typically found in animal products. For example, vegetarians can get vitamin B12 from eggs and dairy, which are excluded from a vegan diet. Therefore, vegans need to pay close attention to their diet to ensure they are getting all the required nutrients.
Despite the potential health benefits of veganism, it is important to note that not all vegan foods are nutritious. Vegan junk food, for example, is still junk food. Additionally, while there are many plant-based foods rich in protein and other nutrients, it may be more challenging for vegans to get enough protein without consuming animal products.

Ovo-vegetarians
Ovo-vegetarianism is a type of vegetarianism that allows for the consumption of eggs but not dairy products. The term ovo-vegetarianism was first used in 1952, with "ovo" derived from the Latin word "ovum", meaning egg. This diet is mostly followed by those who are lactose intolerant or allergic to dairy products.
There are several health benefits associated with ovo-vegetarianism. Research suggests that a vegetarian diet can help lower blood pressure and cholesterol levels, reduce the risk of diabetes, and aid in weight management. Vegetarian diets are typically low in cholesterol and saturated fat and high in antioxidants, contributing to lower blood pressure. Additionally, ovo-vegetarians can obtain sufficient protein from eggs and plant-based sources such as beans, lentils, tofu, and nuts.
However, it is important to ensure adequate nutrient intake on an ovo-vegetarian diet. Some nutrients that may be lacking include iron, calcium, zinc, omega-3 fatty acids, and vitamins D and B12. To compensate, ovo-vegetarians should include whole grains, nuts, seeds, legumes, and fortified foods in their diet. It is recommended to minimise the consumption of unhealthy vegetarian junk foods, such as French fries and cookies, which are highly processed and can be detrimental to health.
Overall, ovo-vegetarianism is a flexible and sustainable dietary choice that can provide health benefits while accommodating those who are lactose intolerant or ethically opposed to certain animal products.

Dairy vegetarians
The concept of lacto-vegetarianism has its roots in ancient India, and it was later promoted in the Western world by physicians and naturopaths in the 18th and 19th centuries. During World War I, Hindhede, a food advisor to the Danish government, played a significant role in introducing a lacto-vegetarian diet to the public. The system of rationing restricted meat and alcohol, resulting in a decrease in mortality and morbidity rates in Denmark.
Lacto-vegetarians obtain calcium, phosphorus, and vitamin D from dairy products, which are essential for bone health. However, it is important to note that some people may be lactose intolerant, and the addition of dairy to replace meat can cause problems for them.
Lacto-vegetarianism is considered a traditional form of vegetarianism. It allows for a variety of food options and can provide nutritional benefits. However, it is important to ensure that the diet is well-planned and includes all the essential nutrients.
