Plant-Based Diets: Vegetarianism's Healthier, Eco-Friendly Cousin?

There is a common misconception that a plant-based diet is the same as a vegetarian one. However, there are some key differences between the two. A plant-based diet focuses on eating whole grains, fruits, vegetables, legumes, nuts, seeds, and healthy oils like olive oil. While it does not include meat as a central part of the diet, small amounts of animal protein may still be consumed. On the other hand, a vegetarian diet excludes meat, fish, and poultry but may include animal by-products such as eggs, milk, and other dairy items.

Plant-based diets can include small amounts of meat, poultry, and fish

A plant-based diet is primarily made up of food from plants, including fruits, vegetables, nuts, seeds, whole grains, legumes, and beans. This does not mean that you are vegetarian or vegan and never eat meat or dairy. Instead, it means that most of your nutrient intake comes from plant-based sources.

There is no set ratio of plant to animal foods on a plant-based diet, but a good way to start is to ensure that at least two-thirds of each plate of food or meal you eat is plant-based. The emphasis is on plants, but animal products are allowed, and eaten less often and in smaller portions. This means that a plant-based diet can include small amounts of meat, poultry, and fish.

A plant-based diet is a lifestyle change, not a diet. It is a very healthy way of eating and can meet all of your nutrient needs. It is nutrient-dense and packed with fiber, healthy fats, protein, vitamins, and minerals. It has been shown to have many health benefits, especially for heart health. Research shows that plant-based diets may prevent and treat chronic diseases and reduce dependence on medications.

A good general guideline to follow if you want to include meat in your plant-based diet is to aim for two meatless meals per day. This means that you are making an effort to reduce your intake of meat and choosing plants as your primary fuel source.

Vegetarian diets exclude meat but may include dairy and eggs

Vegetarian diets are defined by the exclusion of meat, specifically meat, fish, and poultry. However, this does not mean that vegetarians do not eat any animal products. Indeed, vegetarian diets may include animal by-products such as eggs, milk, and other dairy items.

There are different types of vegetarian diets, depending on which animal products are included or excluded. The most common type is the lacto-ovo vegetarian diet, which includes both eggs and dairy foods but excludes meat, poultry, fish, and seafood. Another type is the lacto-vegetarian diet, which includes dairy products but not eggs. Conversely, ovo-vegetarians eat eggs but not dairy products.

Vegetarian diets are often chosen for religious, cultural, or ethical reasons. For example, a person may have concerns for animal welfare, or feel that killing animals for food is unnecessary. Others may be vegetarian because they were raised in a culture or religion that considers animals to be holy or sacred.

Vegetarian diets can be healthy, but careful meal planning is required to ensure adequate nutrient intake. While vegetarians tend to eat more vitamins C and E, dietary fiber, folic acid, potassium, magnesium, and phytochemicals, they may be at risk of insufficient vitamin B12, iron, calcium, zinc, omega-3 fatty acids, and vitamin D. As such, it is important for vegetarians to include alternative sources of these nutrients in their diet or take supplements.

Vegan diets exclude all animal products

Vegan diets are a type of plant-based diet. While plant-based diets do not necessarily exclude animal products, vegan diets do. Vegans do not consume any animal products, including meat, poultry, fish, eggs, and dairy. This also extends beyond food, with vegans avoiding materials such as leather, wool, and silk, as well as products tested on animals.

Veganism is a way of living that seeks to exclude all forms of animal exploitation and cruelty, not just in diet but also in other aspects of life. This means that vegans will avoid products with any animal-derived ingredients, such as additives derived from animals, natural food dyes, and glazing agents.

Some of the animal-derived ingredients that vegans avoid include:

• E120 Carmine, also known as cochineal, carminic acid, or natural red 4, which is made from crushed beetles and used as a red food colouring.
• E441 Gelatine, a gelling agent made from ground-up animal bone and skin, often found in confectionery.
• E542 Bone phosphate, made from ground-up animal bones to keep foods moist.
• E901 Beeswax, a glazing agent made by bees.
• E904 Shellac, a glazing agent made from the secretions of the lac bug.
• E910, E920, E921 L-cysteine and its derivatives, made from animal hair and feathers and used as a proving agent in some breads.
• E913 Lanolin, a greasy substance secreted by sheep and other woolly animals, used in cosmetics and to make vitamin D3.
• E966 Lactitol, a sweetener derived from lactose, which is made from milk.
• Cochineal or carmine, made from ground cochineal scale insects and used as a natural dye to give food a red colour.
• Gelatin, a thickening agent made from the skin, bones, and connective tissues of cows and pigs.
• Isinglass, a gelatin-like substance derived from fish bladders and used in the making of beer and wine.
• Natural flavourings, such as castoreum, a food flavouring that comes from the secretions of beavers' anal scent glands.
• Omega-3 fatty acids, which are mostly derived from fish; omega-3s derived from algae are vegan alternatives.
• Shellac, a substance secreted by the female lac insect and used as a food glaze for candy or a wax coating for fresh produce.
• Vitamin D3, which is mostly derived from fish oil or sheep's wool; vitamin D2 and D3 from lichen are vegan alternatives.
• Dairy ingredients such as whey, casein, and lactose.

Some foods that may be expected to be vegan can also contain animal-derived ingredients, so it is important for vegans to carefully check ingredient lists. These foods include bakery products, beer and wine, sweets and candy, deep-fried foods, pesto, pasta, crisps, roasted peanuts, dark chocolate, fresh produce, and Worcestershire sauce.

A plant-based diet is often chosen for health reasons

Vegetarian diets, on the other hand, typically exclude meat, fish, and poultry but may include dairy and eggs. Vegan diets, a subset of plant-based diets, exclude all animal products.

Plant-based diets offer a range of health benefits. They are associated with a reduced risk of heart disease, high blood pressure, diabetes, and some forms of cancer. They can also lead to lower blood pressure, lower body mass index, and reduced low-density lipoprotein (LDL) cholesterol. The Mediterranean diet, for example, has been shown to reduce the risk of heart disease, metabolic syndrome, diabetes, certain cancers, and depression.

Vegetarian diets can also be healthy, but they allow for more processed and refined foods, fast food, and salty snacks. Well-planned vegetarian diets can be nutritious, but they may require careful meal planning to ensure sufficient nutrient intake.

When choosing a plant-based diet, it's important to remember that not all plant-based options are automatically healthy. Some processed plant-based foods, such as cookies, French fries, and ice cream, are high in added sugar, salt, and refined carbohydrates. Therefore, it's crucial to read nutritional labels and choose products wisely.

Overall, a plant-based diet centered on whole, minimally processed plant foods is a healthy choice that can provide numerous benefits and reduce the risk of chronic diseases.

Vegetarian diets are often chosen for religious, cultural, or ethical reasons

Religious Reasons

Vegetarianism is often chosen for religious reasons, with many religions preaching respect for all living beings and adopting nonviolence principles, such as Hinduism, Jainism, Sikhism, Buddhism, the Hare Krishna movement, and the Seventh-day Adventist Church.

Cultural Reasons

Vegetarianism is also influenced by cultural factors, with some cultures considering certain animals sacred and unsuitable for consumption. For example, in India, cows are considered sacred and not consumed.

Ethical Reasons

Ethical concerns are the main reason for adopting a vegetarian diet, with many people believing that animal slaughter for human consumption is morally inappropriate. Some also believe that eating meat supports cruelty to animals, as it involves keeping animals in cramped and oppressive conditions on factory farms. Additionally, vegetarianism is seen as a way to promote global peace, as it aligns with the principle of nonviolence.
