Vegan Diet: Healthy, Happy, And Humane

A vegan diet is a way of eating that seeks to exclude all animal products and by-products. Vegans do not eat meat, poultry, fish, eggs or dairy, and some also avoid honey. Instead, a vegan diet is based on plants, including fruits, vegetables, grains, nuts, seeds, legumes and plant-based alternatives to animal products.

People choose to follow a vegan diet for a variety of reasons, including ethical, health and environmental concerns. Ethical vegans believe that all creatures have a right to life and freedom, and oppose the killing and exploitation of animals for human gain. Many also oppose the intensive farming methods used to produce animal products. Health-conscious vegans may be motivated by research that suggests a vegan diet can lower the risk of certain diseases, including cancer, heart disease and type 2 diabetes. Environmental vegans avoid animal products because of the environmental damage caused by the farming of animals, which requires more resources and causes higher emissions than plant-based alternatives.

What do vegans eat?

Vegans eat a variety of foods, typically replacing meat, eggs, and dairy with plant-based alternatives. This provides a lot of versatility to a vegan diet.

A vegan diet includes only plant-based foods such as fruits, vegetables, beans, grains, nuts, and seeds. Vegans do not eat any animal foods, including dairy, eggs, and honey.

• Beans, peas, and lentils: such as red, brown, or green lentils; chickpeas; split peas; black-eyed peas; black beans; white beans; and kidney beans
• Soy products: such as fortified soy milk, soybeans, and products made from them, such as tofu, tempeh, and natto
• Nuts: such as peanuts, almonds, cashews, and their butters
• Seeds: such as sunflower seeds, sesame seeds, and their butters, as well as flaxseed, hemp seeds, and chia seeds
• Whole grains: such as quinoa, whole wheat, whole oats, and whole grain brown or wild rice, as well as products made from these foods, such as whole grain bread, crackers, and pasta
• Starchy vegetables: such as potatoes, sweet potatoes, corn, squash, beets, and turnips
• Non-starchy vegetables: such as broccoli, cabbage, asparagus, radishes, and leafy greens; these may be raw, frozen, canned, dried, or pureed
• Fruits: such as apples, pears, bananas, berries, mango, pineapple, oranges, and tangerines; these may be purchased fresh, frozen, canned, dried, or pureed
• Other plant-based foods: such as algae, nutritional yeast, fortified plant milks and yogurts, and maple syrup

Vegan diets are made up of only plant-based foods. This type of diet includes fruits, vegetables, soy, legumes, nuts and nut butters, plant-based dairy alternatives, sprouted or fermented plant foods, and whole grains.

There are different types of vegan diets, including:

• Raw vegan diet: Raw vegans eat only raw plant foods. A raw vegan diet consists mainly of uncooked fruits and vegetables, raw nuts and seeds, sprouted and soaked grains, cold-pressed oils, and fermented foods such as kimchi and miso.
• Vegan keto diet: The keto diet is a very low-carb, high-fat, and moderate-protein diet. On this diet, you aim for 75%-80% of your calories to come from fat, 10%-20% from protein, and 5%-10% from carbs.
• Vegan diabetic diet: A diabetic diet is moderately low in carbohydrates, especially high-glycemic, refined carbs that quickly raise blood sugar.
• High-protein vegan diet: Protein is one of the nutrients often lacking in a vegan diet. A high-protein vegan diet focuses on higher-protein plant foods.
• Alkaline vegan diet: The alkaline diet prioritizes foods based on their pH value. Foods with a low pH are considered acidic, and foods with a high pH are alkaline.
• Vegan anti-inflammatory diet: Balanced vegan diets are naturally anti-inflammatory.
• Mediterranean vegan diet: This is the vegan version of the popular Mediterranean diet. It's rich in fruits, vegetables, grains, beans, nuts, seeds, and unsaturated oils.

Vegans tend to avoid animal products for ethical, health, or environmental reasons or a combination of the three.

What don't vegans eat?

Vegans do not eat any foods that come from animals, including meat, poultry, fish, eggs, dairy products, and honey. This means that vegans do not eat beef, pork, lamb, chicken, duck, shellfish, milk, cream, ice cream, cheese, butter, mayonnaise (because it includes egg yolks), and other animal-derived products.

Some less obvious animal-derived ingredients that vegans avoid include albumin, casein, carmine, gelatin, pepsin, shellac, isinglass, and whey.

Vegans also avoid wearing or using animal products, such as leather, wool, fur, and cosmetics that have been tested on animals.

The health benefits of veganism

Veganism is a practice that involves abstaining from the use of animal products and the consumption of animal source foods. Vegans do not eat any animal foods, including dairy, eggs, and honey. A vegan diet is based on plants such as vegetables, grains, nuts, and fruits, as well as foods made from plants.

Weight Loss

Vegan diets are often associated with weight loss. Observational studies suggest that vegans tend to be thinner and have lower body mass indexes (BMIs) than non-vegans. Several randomised controlled studies have also reported that vegan diets are more effective for weight loss compared to other diets.

Lower Risk of Type 2 Diabetes

Vegan diets are linked to a lower risk of developing type 2 diabetes. Vegans tend to have lower blood sugar levels and higher insulin sensitivity. A vegan diet may also help manage existing diabetes by lowering A1C levels.

Improved Kidney Function

Following a vegan diet may also improve kidney function. A 2009 study found that 43% of participants following a vegan diet were able to reduce their dosage of blood sugar-lowering medication, compared to only 26% of participants following a non-vegan diet.

Lower Risk of Certain Cancers

Adopting a vegan diet may also reduce the risk of developing certain types of cancer. Vegans generally consume more legumes, fruits, and vegetables, which may explain why a 2017 study found that vegans have a 15% lower risk of developing cancer.

Improved Heart Health

Vegan diets are associated with improved heart health. Well-planned vegan diets typically include higher amounts of fresh fruits and vegetables, legumes, and fibre, which are linked to a lower risk of heart disease. Observational studies have reported that vegans may benefit from up to a 75% lower risk of developing high blood pressure.

Reduced Arthritis Symptoms

Some studies have reported positive effects of a vegan diet on individuals with different types of arthritis. A small study found that participants with arthritis who followed a vegan diet reported higher energy levels and better general functioning compared to those who did not change their diet.

Other Benefits

Vegan diets may also provide other health benefits, such as lower cholesterol levels, reduced risk of certain types of cancer (e.g. colon cancer), and improved management of diabetes.

Considerations

While veganism offers a range of health benefits, it is important to ensure a well-planned and balanced diet to avoid potential nutrient deficiencies. Vitamin B12, for example, is primarily found in animal products, so vegans may need to include fortified foods or supplements in their diet.

In conclusion, a vegan diet can provide numerous health benefits, but it is important to ensure a varied and balanced intake of plant-based foods to meet all nutritional needs.

The health risks of veganism

A vegan diet is a plant-based diet that excludes all animal products, including meat, poultry, fish, eggs, and dairy. Vegans also avoid using materials that originate from animals, such as leather and wool, and they do not use products that have been tested on animals.

While a vegan diet can be very nutritious, there are some potential health risks associated with it. Here are four to six paragraphs detailing the health risks of veganism:

Nutrient Deficiencies:

A vegan diet can lead to nutrient deficiencies, including calcium, iron, vitamin B12, iodine, selenium, and zinc. Vitamin B12, in particular, is only available in animal foods, and vegans are at a high risk of developing a deficiency, which can have irreversible health consequences. Iron deficiency is also common among vegans, as iron from plant-based foods is not as easily absorbed by the body. This can lead to iron-deficient anemia, causing fatigue and other serious symptoms.

Increased Risk of Stroke:

A study published in the medical journal The BMJ found that vegetarians may have a 20% higher risk of stroke compared to meat-eaters. However, the overall risk was small, and the findings may have been influenced by other factors, such as family history. More research is needed to confirm these results.

Risk of Anemia:

As mentioned earlier, iron deficiency is a concern for vegans, and it can lead to iron-deficient anemia. This is the most common nutritional deficiency worldwide, and both vegans and vegetarians are at higher risk. While plant foods contain non-heme iron, it is not as easily absorbed by the body, and anemia can lead to fatigue and other health issues.

Low Omega-3 Fatty Acid Intake:

Vegans may have a higher risk of depression due to low omega-3 fatty acid intake, which is commonly found in fish or fish oils. While algae-based sources of omega-3 fatty acids are an option, they can be expensive and hard to find. Consuming too many nuts, which are high in omega-6 fatty acids, can also throw off the balance of fatty acids in the body.

High Carbohydrate Intake:

Vegan diets can be lower in protein and higher in carbohydrates, which can cause blood sugar swings and lead to health issues such as non-alcoholic fatty liver disease. Legumes, often consumed as a protein source, are very high in carbohydrates. Vegans may also replace protein sources with refined carbohydrates, further increasing their carbohydrate intake.

Disordered Eating:

Orthorexia, an eating disorder characterized by an obsession with healthy eating patterns, may be more prevalent among vegans and vegetarians. Restrictive diets like veganism are not recommended for individuals recovering from eating disorders, as they can trigger or exacerbate disordered eating patterns.

It is important to note that a well-planned vegan diet can help mitigate these health risks. Including a variety of plant-based foods and supplements can ensure that vegans get all the necessary nutrients. Consulting a healthcare professional can help individuals determine if a vegan diet is suitable for them and how to address any potential deficiencies.

The ethics of veganism

Veganism is a way of living that seeks to exclude all forms of animal exploitation and cruelty, whether for food, clothing, or any other purpose. Ethical vegans strongly believe that all creatures have a right to life and freedom, and view all animals as conscious beings that wish to avoid pain and suffering. They are opposed to killing animals for food or using animal products such as leather and wool.

Veganism is often adopted for ethical, health, or environmental reasons. Those who follow a vegan diet typically do so for the perceived health benefits or to advocate for animal rights. Research has shown that vegan diets rich in plant-based foods are associated with improved blood glucose and blood pressure, and lower LDL cholesterol. However, there are some nutrients that individuals following a vegan diet should be mindful of, including vitamin B12, calcium, iron, and certain omega-3 fatty acids.

Some people choose a vegan diet for its potential health benefits, as diets high in meat, especially red meat, have been linked to cancer, heart disease, and type 2 diabetes. Plant-based diets have been linked to a lower risk of developing or prematurely dying from these diseases. Additionally, a vegan diet can help minimize the side effects linked to the antibiotics and hormones used in modern animal agriculture.

Others adopt veganism due to environmental concerns. Animal agriculture heavily contributes to greenhouse gas emissions, and meat eaters are thought to be responsible for 2-2.5 times more of these emissions than those following a vegan diet. Ruminant animals, such as cattle, sheep, and goats, emit the largest amount of greenhouse gases per gram of protein they deliver. As a result, diets that reduce or eliminate dairy also produce significantly fewer emissions.

Veganism also has a long historical background, with roots in ancient times. The term "veganism" itself was coined in 1944 by Donald Watson, with the aim of differentiating it from vegetarianism, which accepts the consumption of milk, dairy products, and eggs.
