Veganism: Unhealthy And Unsustainable

A vegan diet is a plant-based diet that does not include any animal products, including meat, dairy, eggs, and honey. While a vegan diet can be nutritious and ethical, there are several reasons why one might choose not to follow it. Firstly, vegans may be deficient in important nutrients such as vitamin B12, creatine, and certain fatty acids, which can lead to negative health outcomes. Secondly, there is a lack of scientific evidence from controlled trials showing that vegan diets are superior to other diets in terms of health benefits. Additionally, proponents of veganism are often accused of using fear-mongering tactics to promote their cause, and there is no health reason to completely avoid animal products. Furthermore, a vegan diet can be restrictive and challenging to plan, especially for those transitioning from a typical Western diet. Finally, the term vegan diet itself can be confusing, as veganism is often considered a lifestyle and ethical framework rather than just a diet.

Vegans are deficient in many important nutrients, including vitamin B12 and creatine

Vegans are at risk of deficiency in many important nutrients, including vitamin B12 and creatine. Vitamin B12 is an essential nutrient that is almost exclusively found in animal-sourced foods, such as fish, meat, dairy products, and eggs. It is a water-soluble nutrient involved in developing red blood cells and maintaining nerves and normal brain function. Vegans who do not take supplements are at a higher risk of vitamin B12 deficiency than vegetarians.

Creatine is a molecule found in animal foods and is stored as high-energy phosphates in the form of phosphocreatine, which helps produce ATP (adenosine triphosphate). ATP is the primary energy used by the body during periods of high energy, such as intense physical or mental activity. About half of the body's creatine supply comes from the diet, so a prolonged period of following a plant-based diet may lead to a creatine deficiency.

The body needs vitamin B12 to maintain healthy blood and a healthy nervous system. Many people get vitamin B12 from animal sources, such as meat, fish, and dairy products. Sources for vegans are limited, and a vitamin B12 supplement may be needed. Sources of vitamin B12 for vegans include fortified breakfast cereals, unsweetened soya drinks fortified with vitamin B12, and yeast extract, such as Marmite, and nutritional yeast flakes, which are fortified with vitamin B12.

The average person needs 1-3g of creatine per day, and athletes may need to consume between 5-10g per day to maximise performance. Creatine supplements can help improve strength and power output, leading to increases in lean mass and faster, more complete recovery. However, supplements alone will not make you stronger and more powerful; training, sleep, and overall nutrition are still key.

Vegans who are pregnant or breastfeeding need to ensure they get enough vitamins and minerals for their child to develop healthily. It is crucial for these diets to be well-planned and balanced.

There are no studies showing vegan diets are better than other diets

There is a common misconception that vegan diets are superior to other diets. However, this claim is not supported by scientific evidence. While a well-planned vegan diet can be nutritious and provide various health benefits, there is no conclusive evidence that it is better than other diets. Here are some key points to consider:

Lack of Controlled Trials

Despite assertions from proponents of veganism, there is a dearth of controlled trials demonstrating the superiority of vegan diets over other dietary approaches. The claim that low-carb, high-fat diets are dangerous and that vegan diets are unequivocally superior is not supported by rigorous scientific investigation.

Observational Studies and Confounding Factors

Some studies have shown health benefits and lower mortality rates among vegetarians and vegans. However, it is essential to note that these are primarily observational studies, which can only establish correlation, not causation. The improved health outcomes among vegetarians and vegans may be attributed to other factors such as overall health consciousness, increased vegetable consumption, lower smoking rates, and higher physical activity levels.

Comparison with Other Diets

When compared to other specific diets, vegan diets do not consistently outperform them. For example, in the A to Z study, the Atkins (low-carb, high-fat) diet led to greater improvements in weight loss, blood pressure, HDL ("good") cholesterol, and triglyceride levels compared to the Ornish (low-fat, near-vegan) diet. This suggests that vegan diets may not be superior in terms of health outcomes when compared to other dietary patterns.

Nutritional Deficiencies

Vegan diets can lead to nutritional deficiencies, particularly in vitamin B12, which is primarily found in animal-based foods. Vitamin B12 is critical for various bodily functions, including blood formation and brain function. Other nutrients that may be deficient in vegan diets include creatine, carnosine, docosahexaenoic acid (DHA), and specific amino acids. These deficiencies can have negative impacts on overall health and well-being.

Long-Term Health Impacts

While vegan diets may provide short-term health benefits, there are concerns about their long-term effects. The exclusion of animal-based foods can result in micro and macronutrient deficits, which may lead to adverse health outcomes over time. Additionally, the higher prevalence of mental health issues among vegans and the potential impact on fetal development further underscore the need for caution when considering a vegan diet as superior.

In conclusion, while a vegan diet can be a valid choice for some individuals, there is insufficient evidence to claim that it is superior to other diets. Well-designed, controlled studies are necessary to establish the long-term health impacts of vegan diets compared to other dietary approaches. Until then, it is essential to respect individual dietary choices and not propagate misinformation or fear-mongering.

Vegan diets can be very restrictive, which could lead to a lack of important nutrients

Vegan diets can be very restrictive, and this has the potential to lead to a lack of important nutrients. Vegans do not eat any animal products, including meat, fish, dairy, eggs, and honey. This means they are at risk of missing out on certain nutrients that are primarily found in these foods.

For example, vitamin B12 is critical for life and is mostly found in animal products. Vegans must, therefore, be mindful of their vitamin B12 intake and may need to take supplements to avoid a deficiency. Similarly, vegans may need to supplement their diet with vitamin D, calcium, protein, and iron.

A well-planned vegan diet can provide all the nutrients required to be healthy, but it is more restrictive than vegetarian or meat-based diets, and it can be challenging to plan balanced meals. It is important to focus on variety, including fruits, vegetables, whole grains, beans, nuts, seeds, and fortified plant-based dairy products in the diet.

In addition to the potential for nutrient deficiencies, vegan diets may also be challenging for those with certain health conditions, such as diabetes, heart disease, or kidney disease. It is recommended that individuals with pre-existing health conditions consult a doctor or dietitian before transitioning to a vegan diet to ensure they are meeting all their nutritional needs.

There is no health reason to completely avoid animal foods

Humans have been eating meat for hundreds of thousands, if not millions, of years. Our bodies are perfectly capable of digesting, absorbing, and making full use of the many beneficial nutrients found in animal foods.

It is true that processed meat can be harmful, and that the way "conventionally raised" animals are treated is disgusting. However, animals that are fed natural diets (e.g. grass-fed cows) and given access to the outdoors are completely different. Unprocessed red meat, which has been demonized in the past, does not have any association with cardiovascular disease, diabetes, or the risk of death. It has only a very weak link with an increased risk of cancer, and this is probably caused by excessive cooking, not the meat itself.

Animal foods such as meat, fish, eggs, and dairy products are extremely nutritious. They are loaded with high-quality protein, healthy fats, vitamins, minerals, and various other nutrients that have important effects on health.

For example, vitamin B12 is critical for life and is involved in the function of every cell in the body, especially in the formation of blood and the function of the brain. B12 deficiency is very common in vegans, with one study showing that 92% of vegans are deficient in this nutrient. Animal protein also contains all the essential amino acids in the right ratios, which is important for muscle mass and bone health.

There may be ethical or religious reasons to avoid eating animals, but there is no scientifically valid health reason to completely eliminate animal foods.

It is important to note that a vegan diet can be healthy if it is well-planned and balanced. A balanced vegan diet can provide all the nutrients needed to be healthy, but it requires good planning and an understanding of what makes up a healthy, balanced vegan diet. Without proper planning, vegans could miss out on essential nutrients such as calcium, iron, vitamin B12, iodine, and selenium. Additionally, vegans who are pregnant or breastfeeding need to ensure they get enough vitamins and minerals for their child to develop healthily.

It can be harder to plan a balanced vegan diet

A vegan diet can be harder to plan than other diets because vegans are more limited in their food choices. A balanced vegan diet requires a good understanding of what constitutes healthy, balanced vegan eating and careful planning to ensure the body gets all the nutrients it needs.

A vegan diet is based on plants, including vegetables, grains, nuts, fruits, and foods made from plants. Vegans do not eat any animal products, including meat, fish, dairy, eggs, and honey.

A well-planned vegan diet can provide all the nutrients a person needs, but it is easy to miss out on essential nutrients such as calcium, iron, vitamin B12, iodine, and selenium. For example, vegans can get calcium from green leafy vegetables, fortified unsweetened soya, pea and oat drinks, sesame seeds, and tahini, but it can be harder to get enough calcium without eating dairy foods.

Vitamin B12 is another important nutrient that is mostly found in animal products, so vegans need to ensure they eat foods fortified with B12, such as breakfast cereals, or take a supplement.

Other nutrients that vegans may need to take particular care to include in their diet include vitamin D, iodine, selenium, and omega-3 fatty acids.

A vegan diet can be particularly challenging for people with pre-existing health conditions, such as diabetes, heart disease, obesity, or a gastrointestinal disorder. It is recommended that anyone with a health condition consults a doctor or dietician before starting a vegan diet to ensure they are getting the right nutrients.

It is also important to remember that a vegan diet is not automatically healthy. It is possible to eat a vegan diet that is high in fat and processed foods, which could lead to similar health problems to a meat-based diet.
