Vegan Diets: Should You Make The Switch?

Should you go on a vegan diet? The answer to this question is a personal one and depends on your values, health, and lifestyle. A vegan diet is based on plants and foods made from plants, excluding all animal products, such as meat, fish, dairy, eggs, and honey. Here are some reasons why someone might consider going on a vegan diet:

Health Benefits

Following a well-planned vegan diet can provide all the necessary nutrients and is suitable for every age and stage of life. Research suggests that vegans tend to have lower blood pressure and cholesterol and lower rates of heart disease, type 2 diabetes, and certain types of cancer. A vegan diet is typically high in fibre and low in cholesterol, protein, calcium, and salt. However, it is important to ensure adequate intake of certain nutrients like vitamin B12, vitamin D, calcium, iron, and omega-3 fatty acids, which may require supplementation or consumption of fortified foods.

Environmental Impact

Adopting a vegan diet is one of the most effective ways for an individual to lower their carbon footprint and reduce their impact on the planet. Animal agriculture, particularly meat production, contributes significantly to deforestation, habitat loss, species extinction, and water usage. A plant-based diet requires less land and resources, helping to reduce environmental damage and increase sustainability.

Animal Welfare

A vegan lifestyle prevents the exploitation and slaughter of animals, promoting compassion and standing against animal cruelty. Factory farming methods often involve inhumane conditions and cruel practices, causing unnecessary suffering to animals.

Personal Values and Ethics

For some, the ethical arguments against eating industrially farmed animals are compelling. Additionally, the idea of speciesism, where the exploitation of animals is justified based on their species, is seen as a form of discrimination similar to racism or sexism.

Weight Loss and Energy

Vegan diets are associated with lower body mass indexes and can help with weight loss. Vegans also tend to have higher energy levels due to the absence of cholesterol and saturated animal fats in their diet.

Delicious Food Options

Vegan food options are becoming increasingly diverse and delicious, with companies offering meat and dairy-free alternatives that taste great and are much healthier.

In conclusion, there are several compelling reasons why someone might consider going on a vegan diet, including health benefits, environmental impact, animal welfare, personal values, and weight loss. However, it is important to note that a vegan diet requires proper planning to ensure adequate nutrient intake, and individuals should consult a healthcare professional or registered dietician before making any significant dietary changes.

Animal cruelty

Animal agriculture is a cruel industry. In the UK alone, around 1 billion animals are farmed and slaughtered for consumption annually, and this figure does not even include fish and other marine animals. The vast majority of these animals are raised in intensive conditions, commonly known as factory farming.

On factory farms, animals are forced to live in cramped, windowless sheds with no natural sunlight, fresh air, or grass. They are often injured due to the stressful conditions and live in environments that are breeding grounds for disease outbreaks. Many of their natural instincts and needs are denied, all in the name of producing meat and dairy products as quickly and cheaply as possible. As a result, many animals die before they even leave the farm, and the rest face a brutal death at the slaughterhouse.

Labels like "free-range" and "organic" do little to improve conditions for animals. Investigations have uncovered shocking scenes of animal cruelty in farms and slaughterhouses that are considered to be "high welfare" and "certified organic".

The dairy industry is particularly cruel. Dairy cows face a lifetime of forced impregnation and have their babies taken away from them. When they are no longer considered profitable, they are sent to the slaughterhouse. Male calves in the dairy industry are either sent to veal farms, killed shortly after birth, or exported to other countries for consumption.

The egg industry is no better. Male chicks are seen as a useless byproduct and are often gassed to death at just one day old. Other permitted methods include being minced while alive and fully conscious. Egg-laying hens suffer from mutilations such as de-beaking and are forced to live in packed cages and sheds, where disease and illness are common. At about 18 months old, when they can no longer produce enough eggs to be profitable, they are sent to the slaughterhouse.

The fishing industry also causes immense suffering to animals. Fish feel pain, and ripping them from the sea causes them horrific suffering. Additionally, non-target species such as whales, dolphins, and turtles often get caught in fishing nets and die.

By going vegan, you can help stop this cruelty. Refusing to pay for animal products reduces the demand for them, which ensures fewer animals suffer and die.

Health benefits

A vegan diet can have many health benefits, but it is important to consult a healthcare professional before making any significant dietary changes. Here are some potential health benefits of a vegan diet:

Weight Loss

Following a vegan diet may support weight loss. Plant-based protein sources tend to be lower in calories than animal products, and a vegan diet is naturally lower in calories, making calorie counting and portion control less necessary. Observational studies suggest that vegans tend to have lower body mass indexes (BMIs) than non-vegans, and several controlled studies have found that vegan diets are more effective for weight loss than other diets.

Heart Health

A vegan diet may also support heart health and reduce the risk of heart disease. This is because vegan diets are typically rich in whole grains, legumes, fruits, and vegetables, which are associated with a lower risk of heart disease and stroke. In addition, following a vegan diet may help lower blood pressure and improve cholesterol levels, particularly in men.

Blood Sugar Control and Diabetes Risk

Adopting a vegan diet may help with blood sugar control and reduce the risk of type 2 diabetes. Vegan diets tend to be rich in lower glycaemic index (GI) foods, which are high in dietary fibre and help stabilise blood sugar. People who follow a vegan diet also tend to have higher insulin sensitivity and lower blood sugar levels, reducing the risk of developing type 2 diabetes.

Cancer Risk

Eating a vegan diet may also reduce the risk of certain types of cancer. This is because vegan diets are typically high in legumes, fruits, and vegetables, which are associated with a lower risk of cancer. In addition, avoiding animal products may help reduce the risk of prostate, breast, stomach, and colorectal cancers, as these are thought to be promoted by the consumption of red meat, smoked meat, and processed meats.

Gut Health

Switching to a vegan diet can lead to rapid and positive changes in the gut microbiome, increasing the number and diversity of beneficial microbes. This is because plant-based diets are typically high in dietary fibre, which feeds gut bacteria and allows them to flourish. A diverse microbiome is important for fighting disease, as a loss in species diversity has been linked to negative health outcomes.

Environmental impact

A vegan diet is widely regarded to be better for the planet than diets that include animal products. However, not all plant-based foods have a small environmental footprint.

Positive Impacts

According to the United Nations' Intergovernmental Panel on Climate Change, shifting diets from meat and other animal products to plant-based foods has a high potential for reducing carbon footprints and mitigating climate change. A report from the United Nations Environment Programme states that animal products, both meat and dairy, generally require more resources and cause higher emissions than plant-based alternatives.

A vegan diet is probably the single most effective way to reduce your impact on the planet, not just in terms of greenhouse gases, but also global acidification, eutrophication, land use, and water use. A quarter-pound Beyond Burger, for example, generates 90% less greenhouse gas emissions, requires 46% less energy, 99.5% less water, and uses 93% less land compared to the production, packaging, and distribution of a quarter-pound beef burger in the United States.

Multiple reports have found that a vegan diet has the most potential for reducing greenhouse gas emissions. A vegan diet could reduce global agricultural emissions by 84% to 86%, and the reduction in air pollution would prevent approximately 236,000 premature deaths per year. If animal agriculture were phased out over 15 years, greenhouse gas emissions could stabilize for 30 years and offset 68% of carbon dioxide emissions through the remainder of this century.

Smaller shifts towards plant-based diets can also have a large impact. Globally, replacing 50% of animal-sourced foods with plant-based alternatives would reduce agricultural and land-based emissions by 31% by 2050, while also increasing food security. In the United States, replacing half of all animal-based foods with plant-based foods could result in a 35% decrease in diet-related emissions, reducing roughly 224 million metric tons of emissions annually by 2030.

Negative Impacts

Some plant-based foods can have a disproportionately negative impact on the environment. For example, avocados, almonds, and cashew nuts are water-intensive crops, requiring large amounts of water, pesticides, and fertilizers. Similarly, the production of cocoa and soy has been linked to deforestation, particularly in sensitive biodiversity hotspots.

Additionally, the transportation of fruits and vegetables can contribute to a higher carbon footprint. Delicate fruits like blueberries and strawberries are often imported by air to fill gaps when local fruits are out of season, resulting in higher greenhouse gas emissions.

While a vegan diet has the potential to significantly reduce environmental impact, it is important to be mindful of the specific plant-based foods consumed and their sources. Some vegan foods may have a higher environmental cost than others. Overall, a vegan diet is still considered to be better for the environment than diets that include animal products.

Weight loss

A vegan diet can be an effective way to lose weight, but it is not a guarantee. Vegans tend to be thinner than non-vegans, and studies have shown that a vegan diet can lead to an average weight loss of 4.1kg (9lb) over three months, or 5.6 pounds in 18 weeks. However, results may vary depending on the individual, and there are several factors to consider when using a vegan diet for weight loss.

Firstly, it is important to understand the potential complications of a vegan diet. Vegan diets are already quite restrictive, and adding further restrictions for weight loss may be challenging to maintain. It is crucial to ensure proper nutrition and not simply focus on weight loss, as this can lead to unhealthy habits and yo-yo dieting. Additionally, rapid weight loss can have physical risks such as fatigue, headaches, constipation, dizziness, and malnutrition.

To lose weight on a vegan diet, it is recommended to focus on nutrient-dense foods that are low in calories but high in nutrients. These include fruits, vegetables, whole grains, beans, legumes, nuts, and seeds. High-fiber foods are particularly beneficial, as they promote fullness and slow digestion, making it easier to maintain a calorie deficit. It is also important to limit processed foods, even if they are vegan, as they may contain oils and ingredients that contribute to weight gain.

When adopting a vegan diet for weight loss, it is crucial to be mindful of portion sizes and overall calorie intake. Women typically need 2,000 calories per day to maintain weight and 1,500 calories to lose weight, while men need 2,500 and 2,000 calories, respectively. It is also important to be cautious of ""healthy" drinks and plant-based desserts, as these can still contain high amounts of sugar and calories.

In addition to diet, physical activity plays a crucial role in weight loss. Engaging in regular exercise, such as walking, cycling, or strength training, can help burn more calories and promote weight loss. It is also beneficial to address other factors that may impact weight loss, such as sleep, stress levels, and emotional eating.

While a vegan diet can be an effective tool for weight loss, it is important to remember that individual results may vary, and it is always advisable to consult with a healthcare professional before making significant dietary changes.

Energy levels

Many people experience a boost in energy after switching to a vegan diet. This may be due to the removal of processed meat, which is common in omnivorous diets, and its replacement with fruit, vegetables, and nuts. A vegan diet may also lead to an increase in vitamin, mineral, and fibre intake, which can contribute to higher energy levels.

However, it is important to note that the connection between veganism and energy is not entirely clear. The increase in energy may be a result of adopting a generally healthier diet, especially one that avoids sugary treats and processed foods, which can cause sharp spikes and crashes in blood glucose levels.

To maintain optimal energy levels on a vegan diet, it is crucial to ensure a proper balance of nutrients. This includes consuming a variety of whole, fibre-rich, and complex carbohydrates, along with healthy fats, plant-based proteins, vitamins, and minerals.

Some specific vegan foods that can boost energy include:

• Peanut butter or other nut/seed butters
• Potatoes and other carbohydrate-rich root vegetables
• Oats and other whole grains
• Fruits, especially those high in vitamin C
• Beans and lentils
• Tempeh and other soy-based foods
• Nutritional yeast
• Chia seeds and other plant-based sources of omega-3 fatty acids

Additionally, combining iron-rich foods with vitamin C-rich foods can help prevent fatigue. Vitamin B12, which is largely absent from plant-based foods, can be obtained through fortified foods or supplements to support healthy energy levels.

It is worth noting that energy levels are not solely dependent on diet. Adequate sleep, hydration, and healthy lifestyle behaviours also play a crucial role in maintaining consistent energy levels.
