Vegan Diets: Cheaper, Healthier, And More Sustainable

Veganism is on the rise, with an increasing number of people adopting plant-based diets for ethical, environmental, and health reasons. While vegan diets are widely regarded as better for the planet, not all plant-based foods have a small environmental footprint. This article will explore the economic implications of veganism, considering the costs and benefits of vegan diets in terms of environmental sustainability, personal health, and financial savings.

Vegan diets can reduce healthcare costs

In addition to being more affordable, vegan diets have been linked to improved health outcomes, including reduced risk of cardiometabolic diseases such as cardiovascular disease, type 2 diabetes, obesity, and non-alcoholic fatty liver disease. This is because vegan diets tend to be rich in nutrients and fiber, which can help prevent and manage chronic diseases. For example, a UK study found that a plant-based diet could reduce the risk of cancer, heart disease, bone fractures, and stroke.

Furthermore, vegan diets can lead to a reduction in the number of medications needed to treat chronic diseases. This is because plant-based diets can help lower body mass index, blood pressure, HbA1C, and cholesterol levels, which are all risk factors for various diseases. By managing these risk factors through diet, individuals may be able to reduce their reliance on medication, which can result in lower healthcare costs.

Vegan diets have also been associated with improved maternal and fetal health outcomes. A balanced maternal diet is crucial for optimal fetal growth and development. Vegan diets that are properly planned and supplemented can provide adequate nutrition for pregnant and breastfeeding women, reducing the risk of complications and promoting healthy fetal development.

Overall, vegan diets have the potential to reduce healthcare costs by preventing and managing chronic diseases, reducing the need for medication, and improving maternal and fetal health outcomes. By adopting vegan diets, individuals can not only improve their health but also reduce their healthcare expenses.

Vegan diets can reduce environmental damage

Veganism is on the rise, with a fourfold increase in vegans in the UK between 2014 and 2019. The environmental impact of veganism is a key reason for this increase, with meat, and beef in particular, contributing significantly to greenhouse gas emissions.

Reducing Greenhouse Gas Emissions

The environmental impact of meat production is well-documented, with meat and dairy accounting for 11.2% of man-made greenhouse gas emissions. A shift to a vegan diet could therefore have a significant impact on emissions, with scientists believing that a global shift to veganism could lead to a 68% drop in food-related emissions within 15 years.

Reducing Land Use

As well as reducing emissions, a vegan diet could also free up land for other uses. Currently, nearly 80% of the world's farmland is dedicated to rearing animals, and a shift to plant-based diets could cut land use by 76%. This would allow for "rewilding", with ecosystems recovering, carbon dioxide being absorbed from the atmosphere, and species destruction being halted.

Reducing Water Use

Vegan diets can also help to reduce water use. Meat production is a water-intensive process, and some vegan foods have a much lower water footprint. For example, it takes 74 litres of water to make a glass of almond milk, compared to the equivalent of over 200 litres of water for a glass of dairy milk.

Reducing Deforestation

Meat production is also a major driver of deforestation, with beef, pork, and poultry meat having a particularly detrimental impact. A shift to veganism could therefore help to reduce deforestation and protect sensitive biodiversity hotspots.

Reducing Transport Emissions

In addition to the environmental impact of food production itself, the transport of food can also have a significant carbon footprint. Air-transported fruit and vegetables, for example, can create more greenhouse gas emissions than some types of meat. Choosing locally produced, seasonal fruit and vegetables can help to reduce transport emissions.

While veganism can have a positive impact on the environment, it is important to consider the environmental impact of all aspects of food production and transport. Some vegan foods, such as avocados and almonds, can have a high carbon and water footprint. Overall, however, a shift towards plant-based diets has the potential to reduce environmental damage and help to address the climate crisis.

Vegan diets can reduce the risk of certain diseases

Vegan diets are associated with a reduced risk of developing certain diseases. Research has shown that a vegan diet can lower the risk of cardiometabolic diseases such as cardiovascular disease, type 2 diabetes mellitus, obesity, and non-alcoholic fatty liver disease. Additionally, vegans have been found to have a lower risk of cancer, heart disease, and hypertension compared to other dietary groups.

The reduced risk of these diseases among vegans can be attributed to several factors. Firstly, vegans tend to consume more fruits, vegetables, whole grains, and legumes, resulting in higher intakes of beta-carotene, fiber, and omega-3 fatty acids. This diet is also associated with lower intakes of saturated fatty acids, which are linked to heart disease. Secondly, vegan diets can help maintain a healthy weight, as they are often lower in total protein and essential amino acids. Being within a healthy weight range reduces the risk of developing obesity-related diseases such as diabetes mellitus and coronary artery disease.

However, it is important to note that vegan diets may also be associated with some adverse health outcomes. For example, vitamin B12 deficiency is common in vegans due to the exclusion of vitamin B12-rich foods like meat and dairy. This deficiency has been linked to neurologic and hematologic problems and an increased risk of certain cancers. Vegans may also experience mental health issues, such as a higher prevalence of depressive and anxiety disorders, possibly due to nutritional deficiencies.

In conclusion, while vegan diets can reduce the risk of certain diseases, it is crucial to ensure adequate nutrient intake, especially vitamin B12, to mitigate potential health risks associated with a vegan lifestyle.

Vegan diets can be cheaper

Veganism is on the rise, with a fourfold increase in vegans in the UK between 2014 and 2019. A vegan diet can be cheaper than a meat-based diet, and there are several reasons for this.

Firstly, meat is an expensive food product. Beef, lamb, and pork, for example, are some of the most environmentally damaging foods, and they also tend to be costly. By cutting out meat, vegans can save money on their food bills.

Secondly, vegan diets tend to be based on plant-based proteins, which are often cheaper than animal-based proteins. Beans, pulses, and nuts, for example, are usually less expensive than meat or fish.

Thirdly, vegan diets can be healthier, which can lead to reduced healthcare costs. Research has linked plant-based diets to lower rates of heart disease, type 2 diabetes, and some cancers. As a result, a vegan diet may lead to fewer medical expenses over time.

Finally, a vegan diet can free up money for other things. For example, a Swedish study found that a vegetarian diet is around 10% cheaper than a meat-based diet, which frees up about 2% of an individual's budget. This extra money can be spent on other things, or saved.

Overall, a vegan diet can be cheaper than a meat-based diet due to the lower cost of plant-based proteins and the potential for reduced healthcare expenses.

Vegan diets can reduce emissions

Vegan diets are widely regarded as better for the planet than diets that include animal products. However, not all plant-based foods have a small environmental footprint.

The Impact of Meat

Meat, particularly beef, has an unparalleled impact on the planet's greenhouse gas emissions. It also consumes more land and water and causes more environmental damage than any other food product. Even the "greenest" meat sources produce more greenhouse gases than plant-based proteins.

The Benefits of Vegan Diets

According to the United Nations' Intergovernmental Panel on Climate Change, shifting from meat and animal products to plant-based diets has the potential to significantly reduce carbon footprints and mitigate climate change. A report from the United Nations Environment Programme states that animal products generally require more resources and cause higher emissions than plant-based alternatives.

A global shift to a plant-based diet could reduce food production-related mortality and greenhouse gas emissions by 10% and 70%, respectively, by 2050. Additionally, the World Health Organization notes that reducing livestock herds would decrease methane emissions, the second-largest contributor to global warming after carbon dioxide.

The Impact of Vegan Diets on Emissions

The environmental cost of industrialised animal farming is significant. The United Nations estimates that meat and dairy account for 11.2% of man-made greenhouse gas emissions. Scientists believe that if everyone adopted a vegan diet, the world's food-related emissions could drop by 68% within 15 years, helping to limit global warming.

The Impact of Specific Vegan Foods

While vegan diets are generally better for the environment, some specific vegan foods have a higher environmental impact than others. For example, avocados, almonds, and cashew nuts are water-intensive crops, requiring large amounts of water to grow. Similarly, the production of certain vegan foods, such as mushrooms and cocoa, can have a surprising impact on emissions due to the energy required to cultivate them.

While not all vegan foods have a low environmental impact, vegan diets can indeed reduce emissions. By eliminating animal agriculture and adopting plant-based diets, we can effectively halt the increase in atmospheric greenhouse gases and give humanity more time to end its reliance on fossil fuels.
