Plant-Based Diet: What's Off The Menu?

A plant-based diet is a way of eating that focuses on foods derived from plants. While it is not strictly animal-free, it typically contains smaller portions of animal-sourced foods. A plant-based diet excludes meat, poultry, fish, eggs, and dairy products. It also excludes highly processed foods, such as fast food, added sugars and sweets, refined grains, and artificial sweeteners.

Meat

A plant-based diet emphasizes whole, minimally processed foods and prioritizes plants, including vegetables, fruits, whole grains, legumes, seeds, and nuts, which should make up the majority of what you eat. It is a flexible diet, and some people may choose to include small amounts of meat, but the basic principle is to minimize animal products.

The benefits of a plant-based diet include a reduced risk of heart disease, certain types of cancer, obesity, diabetes, and cognitive decline. It is also beneficial for the environment, as it reduces the environmental footprint by lowering greenhouse gas emissions, water consumption, and land use associated with factory farming.

Transitioning to a plant-based diet can be gradual, and it is important to ensure that nutritional needs are met, especially for certain nutrients that are more readily available in meat, such as vitamin B12 and zinc.

Poultry

A plant-based diet is not the same as a vegan or vegetarian diet, although it does share some similarities. A vegan diet excludes all meat and animal products, including meat, poultry, fish, seafood, dairy, and eggs. A vegetarian diet also excludes meat, poultry, fish, and seafood, but there are variations within a vegetarian diet that depend on whether eggs, dairy, and fish are included or excluded. For example, a semi-vegetarian or flexitarian diet includes eggs and dairy and may include small amounts of meat, poultry, fish, and seafood. A pescatarian diet includes eggs, dairy, fish, and seafood but no meat or poultry.

Plant-based diets offer all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health and are often higher in fiber and phytonutrients. They have been shown to have significant health benefits, including reducing the risk of heart disease, diabetes, and obesity.

It is important to note that a plant-based diet is not automatically healthy. It requires careful planning to ensure that all essential nutrients are obtained, especially for pregnant or breastfeeding women, infants, and young children. Additionally, it is important to meet with a healthcare professional or dietitian at least once a year to assess for any deficiencies.

Fish

Vegan and Vegetarian Diets

Vegans and vegetarians do not eat fish. As one source states:

> Fish are animals, not plants.

Veganism is a practice that involves abstaining from the use and consumption of animal products. This includes meat and poultry, as well as fish and shellfish. Vegans also avoid other animal-derived products such as honey, dairy, and gelatin.

Plant-Based Diets

Plant-based diets focus on foods primarily from plants, including fruits, vegetables, nuts, seeds, oils, whole grains, legumes, and beans. However, this does not mean that a plant-based diet is necessarily plant-exclusive. Some plant-based diets allow for moderate amounts of meat, poultry, fish, and seafood. For example, a pescatarian diet includes fish and seafood but not meat or poultry. Another type of plant-based diet, the "ostrovegan" diet, includes bivalve mollusks (such as clams, mussels, oysters, and scallops) in an otherwise vegan diet.

Health Benefits of Plant-Based Diets

Plant-based diets offer all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health, and are often higher in fiber and phytonutrients. Research has shown that following a plant-based diet can lower your risk of heart disease, diabetes, and obesity. Plant-based diets are also associated with lower risks of hypertension (high blood pressure) and colon and breast cancers.

Personal Preferences

Ultimately, deciding whether to include fish as part of a plant-based diet depends on your personal preferences and beliefs. If you are interested in losing weight and preventing heart disease and diabetes, a plant-based diet that includes fish in moderation may be a good option. However, it is important to note that a purely plant-based diet has been linked to a variety of health benefits.

Eggs

There is no universally agreed-upon definition of a "plant-based diet". However, it generally refers to a style of eating that focuses on foods derived from plants, including fruits, vegetables, whole grains, legumes, nuts, seeds, oils, and beans. While some plant-based diets include animal products in small amounts, others exclude them entirely.

The Exclusion of Eggs from Plant-Based Diets

The Argument for Including Eggs

However, some sources argue that eggs can be included in a plant-based diet. Manuel Villacorta, a registered dietitian, endorses the consumption of eggs as part of a plant-based diet. He defines a plant-based diet as a style of eating that includes mainly plant foods but does not necessarily exclude all animal products. Villacorta argues that completely cutting out all animal products could lead to nutrient deficiencies, and that eggs can help prevent these deficiencies while also complementing a plant-based diet.

The Nutritional Benefits of Eggs

Additionally, eggs can be a versatile addition to plant-based dishes, such as stuffed veggies, salads, and baked dishes. They can also be a convenient snack option, providing a good balance of protein, carbs, and healthy fats when paired with fruits or vegetables and a handful of nuts.

The Role of Eggs in a Plant-Based Diet

In summary, while eggs are often excluded from plant-based diets due to their status as an animal product, there are valid arguments for including them. Eggs provide essential nutrients and can enhance the absorption of nutrients from plant foods. When incorporated into plant-based dishes, they can make a nutritious and well-rounded meal. However, it is important to note that the decision to include or exclude eggs from a plant-based diet is ultimately a matter of personal choice and interpretation of the diet.

Dairy

For those adhering to a plant-based diet, dairy products are off the menu because they are not derived from plants. Instead, those on plant-based diets can opt for dairy alternatives, such as milk made from soy, oat, almond, hemp, or coconut. These alternatives can provide similar nutritional benefits to dairy, such as calcium and vitamin D, without the use of animal products.

Some people who follow a plant-based diet may choose to include small amounts of dairy in their meals. This is because a plant-based diet can be flexible and allow for some animal products, depending on individual dietary needs and preferences. However, the basic principles of a whole-foods, plant-based diet are to emphasise whole, minimally processed foods, limit or avoid animal products, and focus on plants.

The exclusion of dairy and other animal products from a plant-based diet can offer several health benefits. Research has shown that plant-based diets are effective at stimulating weight loss and improving health. Specifically, a plant-based diet can help lower body weight, reduce "bad" LDL cholesterol, and lower the risk of heart disease, certain types of cancer, obesity, diabetes, and cognitive decline.

In addition to the health benefits, a plant-based diet that excludes dairy can also be beneficial for the environment. Animal agriculture, including dairy farming, has a significant impact on the environment, contributing to greenhouse gas emissions, water consumption, and land use. By contrast, plant-based diets have a smaller environmental footprint and can help reduce these negative impacts.
