A plant-based diet is one that focuses on foods derived from plants. This includes fruits, vegetables, whole grains, legumes, nuts, and seeds. While some people interpret this diet as strictly avoiding all animal products, others may occasionally consume meat, fish, or dairy products alongside plant-based foods. The key difference between a plant-based and vegan diet is that being vegan extends beyond diet to a lifestyle that avoids using or consuming animals as much as possible. This includes avoiding items made from or tested on animals, such as clothing, personal care products, and medications.

What You'll Learn
A plant-based diet can include small amounts of animal products
A plant-based diet is centred around consuming foods derived from plants, including fruits, vegetables, whole grains, legumes, nuts, seeds, oils, and beans. While this type of diet prioritises plant-based sources, it does not necessarily exclude animal products altogether. In fact, a plant-based diet can include small amounts of animal products, allowing for flexibility and a diverse range of nutrients.
The key distinction between a plant-based diet and a vegan or vegetarian diet lies in the inclusion of animal products. Vegans and vegetarians abstain from meat, with vegetarians also typically refraining from seafood. However, a plant-based diet takes a more inclusive approach, allowing for the occasional consumption of meat and other animal-derived foods. This means that a plant-based diet can include small amounts of animal products, such as poultry, fish, eggs, and dairy.
The inclusion of small amounts of animal products in a plant-based diet is supported by the Mediterranean diet, which serves as a model for healthy eating. The Mediterranean diet is characterised by a foundation of plant-based foods, complemented by the inclusion of fish, poultry, eggs, cheese, and yoghurt a few times a week, with meats and sweets consumed less frequently. This approach demonstrates that a plant-based diet can be flexible and still offer health benefits.
When incorporating animal products into a plant-based diet, it is important to prioritise nutrient-dense options and practice moderation. Animal products can be a good source of essential amino acids, vitamin B12, and heme iron. However, it is advisable to limit the consumption of ultra-processed animal products, such as hot dogs and chicken nuggets, which tend to be high in unhealthy fats and sodium. Instead, opt for whole foods like eggs, salmon, chicken, and shellfish.
By including small amounts of animal products, a plant-based diet can become more sustainable and socially compatible. A purely plant-based diet may pose challenges in terms of nutrient deficiencies and higher cholesterol levels. Therefore, incorporating animal products can help ensure a diverse range of nutrients and a more well-rounded approach to nutrition.

Veganism is a lifestyle, not just a diet
Veganism is a lifestyle and philosophy that seeks to exclude all forms of animal exploitation and cruelty, be it for food, clothing, or any other purpose. It is a conscious choice to live a life that minimises harm and suffering, not just for animals but also for the environment and people.
While a plant-based diet is a significant aspect of veganism, it is just one part of this ethical framework. Vegans abstain from wearing or purchasing products made from animals, such as leather, wool, or fur, and opt for cruelty-free alternatives. They also avoid using products tested on animals, be it cosmetics, household items, or medication.
Entertainment choices are also impacted by veganism. Vegans avoid zoos, circuses, dog or horse racing, and other activities that exploit animals for entertainment. Instead, they may visit and support animal sanctuaries that provide safe and loving homes for rescued animals.
Veganism also extends to landscaping and gardening decisions, where the aim is to minimise the negative impact on wildlife.
The vegan lifestyle is about making ethical choices and embracing alternatives that do not cause harm. It is about recognising that all sentient beings deserve a life free of suffering and taking steps to reduce that suffering wherever possible.
Veganism is a commitment to compassion and empathy, and it is a way of living that seeks to create positive change in the world.

Plant-based diets are associated with health benefits
A plant-based diet is one that focuses on foods derived from plants, including fruits, vegetables, nuts, seeds, oils, whole grains, legumes, and beans. It does not necessarily exclude animal products like meat and dairy but rather emphasises choosing more of your foods from plant sources.
Plant-based diets are associated with numerous health benefits, including:
Lower Risk of Chronic Diseases
Plant-based diets have been linked to a reduced risk of developing various chronic diseases. These include heart disease, with the Mediterranean diet, for example, shown to reduce the risk of heart disease. Plant-based diets are also associated with a lower risk of high blood pressure, diabetes, and certain cancers.
Weight Management
Vegetarian diets have been found to be beneficial for weight management, with vegetarians generally having lower body weights than their meat-eating counterparts. This may be due to the higher consumption of nutrient-dense foods and lower consumption of total fat associated with plant-based diets.
Blood Sugar Management
Several studies have indicated that plant-based diets can be beneficial for both the treatment and prevention of type 2 diabetes. This is possibly due to improved insulin sensitivity and decreased insulin resistance.
Lower Cholesterol Levels
Plant-based diets have been shown to lower cholesterol levels, which may contribute to the reduced risk of heart disease observed in individuals following these diets.
Reduced Medication Needs
Adopting a plant-based diet may also reduce the number of medications needed to manage chronic diseases. This is likely due to the positive impact of these diets on various health markers, such as blood pressure, blood sugar, and cholesterol levels.
While plant-based diets offer many health benefits, it is important to note that not all plant-based diets are equal. The specific benefits may depend on the types of plant-based foods consumed and the overall diet quality. Additionally, some individuals following plant-based diets may need to supplement their diet with certain nutrients, such as vitamin B12, to ensure adequate intake.

Plant-based diets are environmentally friendly
Plant-based diets have been advocated for millennia, and large segments of the world's population have thrived on them. Adopting plant-based diets worldwide seems to be a reasonable alternative for a sustainable future. They can simultaneously optimise the food supply, health, environmental, and social justice outcomes for the world's population.
Plant-based diets focus on whole grains, fruits, and vegetables, while still allowing for small portions of animal products like meat, fish, poultry, and dairy. They offer all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health and are often higher in fibre and phytonutrients.
However, it is important to note that not all plant-based diets are created equal. For example, a plant-based diet rich in fried vegetables and refined grains has been associated with a higher risk of heart disease. Additionally, certain plant-based foods, such as avocados, mangoes, and almonds, have a high water footprint and may contribute to environmental damage.
Overall, plant-based diets have the potential to be environmentally friendly, but it is essential to consider the specific details of the diet and the impact of individual food choices.

A plant-based diet is not automatically healthy
A plant-based diet does not automatically equate to a healthy diet. While it is true that plant-based diets can be beneficial for health, it is important to understand that not all plant-based diets are created equal.
Plant-based diets focus on whole grains, fruits, vegetables, legumes, unsalted nuts, and healthy oils like olive oil. They do not necessarily exclude meat and animal products but rather emphasise choosing more foods from plant sources. The Mediterranean diet, for example, includes plant-based foods as its foundation but also incorporates fish, poultry, eggs, cheese, and yoghurt a few times a week, with meats and sweets less often. This diet has been shown to offer various health benefits, including a reduced risk of heart disease, metabolic syndrome, diabetes, certain cancers, and depression.
However, it is essential to recognise that simply following a plant-based diet does not guarantee improved health. Vegetarian diets, for instance, can include processed and refined foods, fast foods, and salty snacks. A person who consumes a lot of refined grains, canned vegetables, fruit juices, and salty snacks is not eating healthily, even if they are not consuming animal products.
Additionally, plant-based diets may be lacking in certain nutrients. Vegans, in particular, may need to add supplements, such as vitamin B12, to ensure they receive all the required nutrients. Furthermore, some plant foods are considered incomplete proteins, lacking one or more essential amino acids. However, this can be easily addressed by combining plant protein sources, such as having a peanut butter sandwich or hummus with pita bread.
It is also worth noting that plant-based diets are not always lower in calories than meat-based meals. A study analysing fast food meals found that plant-based options had less protein and sodium and more carbohydrates and sugar, with no significant difference in calorie count.
Therefore, while plant-based diets can be a healthy choice, it is important to make informed decisions and ensure a balanced and varied intake of nutrients, just as one would with any other diet.
