Veganism: A Healthier, Happier, And More Sustainable Diet

There are many reasons why someone might choose to adopt a vegan diet. The evidence supporting a vegan diet from an environmental and health standpoint is substantial. Research has shown that a vegan diet is better for your heart, can help feed the hungry, improve your mood, and has been linked to a reduced risk of several chronic conditions. In addition, animal agriculture negatively affects the environment through greenhouse gas emissions, water consumption, and land usage and pollution. Finally, animal welfare is also a key factor in the decision to go vegan, with many people believing that all sentient creatures have a right to life and freedom.

Animal welfare

The conditions in which animals are kept are also a cause for concern. Intensive breeding and factory farming often subject animals to cramped conditions, early separation from their offspring, and painful slaughter processes. These practices prioritise profit over animal wellbeing, resulting in health issues for the animals.

The environmental impact of animal agriculture further exacerbates the issue of animal welfare. Animal agriculture is a significant contributor to greenhouse gas emissions, water consumption, and land usage. The high demand for meat drives industrialised meat production, leading to inhumane practices and a negative impact on the planet.

Some people also believe that killing animals for food is inherently inhumane and unnecessary. With plant-based sources providing all the necessary nutrients, there is an ethical argument for avoiding animal products altogether.

Cultural and spiritual beliefs also play a role in promoting animal welfare. Followers of religions such as Buddhism, Hinduism, and Jainism advocate for benevolence among all species, and traditional African and Caribbean communities have long-standing vegan practices rooted in their ancestral heritage.

Adopting a vegan diet is seen as a way to respect animal welfare, reduce their suffering, and minimise the environmental impact of animal agriculture.

Environmental impact

Adopting a vegan diet can have a significant positive impact on the environment. Animal agriculture is an incredibly water-intensive process. For instance, it can take several thousand litres of water to produce 1kg of beef when accounting for the water needed to grow feed, provide drinking water for the animals, and process the meat. In contrast, crops like lentils or beans require a fraction of that amount. Water is a precious resource, and reducing water consumption can help preserve this vital resource for future generations.

Animal agriculture also contributes significantly to greenhouse gas emissions, with the production of red meat, particularly beef, emitting twice as many greenhouse gases as plant-based foods. Cows produce methane, a greenhouse gas with a much higher global warming potential than carbon dioxide. By reducing or eliminating meat consumption, individuals can play a crucial role in reducing their carbon footprint and mitigating climate change.

In addition to water consumption and greenhouse gas emissions, animal agriculture also has a significant impact on land usage and pollution. Raising animals for meat is generally less land-efficient than growing plants for direct human consumption. The process of raising and killing animals for meat requires vast amounts of land, leading to deforestation and the destruction of natural habitats, which results in a loss of biodiversity.

The environmental impact of animal agriculture extends beyond resource consumption and emissions. The industrialised ways of meat production often result in inhumane treatment and living conditions for animals, with profit being prioritised over animal welfare. This inhumane treatment of animals and the environmental degradation caused by animal agriculture are ethically troubling to many, especially when considering global hunger and the potential to better utilise resources for direct human consumption.

By adopting a vegan diet, individuals can help conserve vital resources, reduce pollution and emissions, preserve biodiversity, and promote more ethical and sustainable practices. It is a comprehensive approach to sustainability, offering benefits not only for personal health but also for the planet. With the growing awareness of the environmental impact of food choices, individuals are increasingly empowered to make conscious decisions about their diets, contributing to a more sustainable future.

Personal health

Adopting a vegan diet has been linked to a multitude of health benefits. Research has shown that vegans, on average, have a lower body mass index (BMI) compared to meat-eaters. This is because vegan diets tend to be rich in dietary fibre and essential nutrients, but relatively low in calories, helping individuals feel full without consuming excess calories, which leads to a healthier weight.

Vegan diets have also been linked to a reduced risk of several chronic conditions. For example, diets high in saturated fats (often derived from animal products) are associated with an increased risk of coronary heart disease (CVD). However, research has shown that CVD is less prevalent among vegans. Similarly, the dietary choices made by vegans could result in better glycaemic control, which is an important factor in the prevention of type 2 diabetes.

High blood pressure, or hypertension, is another condition that can be positively influenced by a vegan diet, potentially due to the increased intake of potassium-rich foods and a reduction in sodium intake. Furthermore, epidemiological studies have indicated a correlation between plant-based diets and a decreased risk of certain cancers, including postmenopausal breast cancer, prostate cancer, and colorectal cancer. This protective effect is attributed to the diet's richness in antioxidant vitamins and micronutrients.

Switching to a vegan diet has also been shown to improve mental health. The high level of antioxidants in fruits and vegetables has beneficial effects on mental health, and carbohydrates like brown rice help regulate serotonin levels, which is important in controlling mood.

Religious reasons

Followers of Buddhism, Hinduism, and Jainism follow a vegan diet, advocating for benevolence among all species. There are also traditional African and Caribbean vegan communities, and Black veganism is historically rooted in pre-colonial African diets, the Civil Rights Movement, and anti-racist advocacy. In Hispanic communities, the diet is regaining popularity, thanks to young community members and groups like the Veggie Mijas, who are reconnecting with their ancestral heritage.

Cultural and spiritual beliefs in non-violence and respect for all life further inspire many to adopt a vegetarian or vegan diet. The earliest known documentation of vegan eating is from 500 BC, when the Greek philosopher Pythagoras, known for the Pythagorean Theorem, wrote about a vegetarian-like diet.

Food intolerances

The most common food items that cause intolerance are dairy (milk and its products, including cheese and butter), gluten, and caffeine, but there are many other common offenders. The symptoms of a food intolerance can begin soon after eating the food, or they may take a few days to appear, making it difficult to identify the offending food. Some common symptoms of food intolerances include bloating, fatigue, diarrhoea, abdominal pain, eczema, nausea, and a runny nose.

Vegan diets can be beneficial for those with food intolerances, as they eliminate some of the most common triggers, such as lactose intolerance, which is caused by dairy products. Additionally, there is evidence that a diet high in fibre and low in saturated fats and proteins, like a vegan diet, can be beneficial for gut health.

However, a vegan diet can also set the stage for new food intolerances to develop. Dramatic shifts in diet, such as those experienced when adopting a vegan lifestyle, can trigger the development of new food intolerances. This is because the change can throw off your system, making it harder to process foods that were previously digestible.

Another concern is the overconsumption of specific foods. Vegans may find themselves relying heavily on certain foods to meet their nutritional needs, and this can lead to the development of intolerances over time. For example, vegans may consume large amounts of soy, which is found in meat substitutes and dairy alternatives. This over-exposure can lead to the development of soy sensitivities.

It is important to note that anyone with a limited diet, not just vegans, is more likely to experience intolerances due to a lack of variety in their food choices. Therefore, it is crucial to ensure a diverse and well-balanced vegan diet to minimise the risk of developing new food intolerances.
