Vegan Diets: Unhealthy And Unsustainable For Humans

Veganism is often touted as a healthy and ethical approach to eating. However, there are several reasons why vegan diets may be a terrible idea and could even be considered unhealthy. Firstly, vegans may suffer from nutrient deficiencies, particularly vitamin B12, creatine, and testosterone. While vitamin supplements can help, they are not always effective or desirable. Secondly, vegan proponents often claim that vegan diets are scientifically superior to other diets, but this is not necessarily true. Carbohydrates, for example, are energy boosters, but excessive consumption can be detrimental. Thirdly, vegans may exaggerate the health risks of consuming meat and ignore the benefits, such as certain nutrients that are more easily obtained from meat. Fourth, any health benefits experienced by vegans may be due to other factors, such as avoiding added sugar, refined carbohydrates, and trans fats, or adopting healthier lifestyle habits like exercising and quitting smoking. Finally, there is no compelling health reason to avoid meat altogether, as unprocessed meat can be a nutritious part of a balanced diet. In conclusion, while veganism may work for some people, it is not necessarily the healthiest or most practical option for everyone.

Nutrient deficiency (e.g. vitamins B12 and D, creatine, calcium, zinc, iodine, iron)

Nutrient deficiency is a common criticism of vegan diets. Some nutrients are only found in animal products, so vegans must be mindful of their diet to ensure they are getting adequate nutrition.

Vitamin B12 is one such nutrient. It is critical for life and plays a role in the formation of blood and the function of the brain. It is mainly found in meat, eggs, and dairy products, so vegans are at a higher risk of deficiency. In fact, one study showed that 92% of vegans were deficient in this nutrient. Common symptoms of B12 deficiency include weakness and fatigue, tingling in the hands and feet, digestive problems, and a sore tongue or mouth ulcers.

Creatine is another nutrient that vegans may be deficient in. Creatine is an amino acid-like compound produced in the liver, kidneys, and pancreas, and it is important for muscle and brain function. While creatine supplements are available, there are no plant-based foods that contain creatine. Vegans can support their body's natural production of creatine by consuming protein-rich plant-based foods such as tempeh, tofu, edamame, textured vegetable protein, and plant-based milk.

Vitamin D is also commonly associated with animal products, as it is found in foods like salmon, egg yolks, and shellfish. However, there are some good vegan sources of vitamin D, including fortified foods like soy milk, breakfast cereals, and orange juice, as well as mushrooms exposed to ultraviolet light during growing. Additionally, the body can produce vitamin D when the skin is exposed to sunlight.

Iodine is another essential nutrient that can be lacking in a vegan diet. The iodine content of plant foods varies depending on how much iodine was present in the growing environment, and it can be difficult to know how much iodine is in these foods. Seaweed is a rich source of iodine for vegans, but regular consumption is not recommended due to the variable amounts of iodine in different types of seaweed. Taking an iodine supplement or consuming a milk alternative fortified with iodine are reliable ways for vegans to ensure they are getting enough of this nutrient.

Iron is another nutrient that vegans may need to be mindful of. While iron is available in dietary sources, vegans may need up to 1.8 times more iron than meat-eaters due to the presence of vitamin C in their diet, which improves the absorption of nonheme iron. Good vegan sources of iron include blackstrap molasses, lentils, tofu, tempeh, spinach, beans, and Swiss chard.

Finally, calcium is an important mineral for vegans to consider. While dairy is often thought of as the main source of calcium, there are also many plant-based sources, including soybeans and foods made from soybeans like tofu, tempeh, and natto; beans, peas, and lentils; nuts, especially almonds and Brazil nuts; seeds and their butters, such as tahini; grains like amaranth and teff; seaweed; and certain fruits and vegetables, including oranges, blackcurrants, blackberries, and raspberries.

Not scientifically better than other diets

Vegan diets are not scientifically better than other diets. While some studies have shown that a vegan diet may be associated with improved health outcomes, such as a reduced risk of cardiometabolic diseases, the negative health repercussions are rarely highlighted.

Veganism has been associated with adverse health outcomes, including nervous, skeletal, and immune system impairments, hematological disorders, as well as mental health problems due to the potential for micro and macronutrient deficits. Vegans have a greater prevalence of mental health problems, which may lead to a poorer quality of life.

A balanced diet should consist of lean meat, nuts, fresh fruits and vegetables, and olive oil. A wholesome diet is essential in maintaining a healthy gut flora, which in turn is pivotal in avoiding inflammatory disorders.

Vegans are at a higher risk of vitamin B12 deficiency since vitamin B12 is only available in animal foods. A lack of vitamin B12 has been linked to neurologic and hematologic problems. Low vitamin B12 intake has serious clinical consequences, although deficient symptoms appear gradually over time. Vegans must get their levels checked regularly and meet their daily requirements via supplements or fortified foods.

Vegans also have a zinc deficit. Meat, dairy, and eggs contain zinc, but some zinc-rich plant foods (e.g., nuts, seeds, and whole grains) have poor bioavailability due to the presence of phytate, which inhibits absorption in the gut. Inadequate zinc consumption may be associated with mental health problems (e.g., depression), dermatitis, diarrhea, and alopecia, all of which are more prevalent among vegans.

Additionally, vegans have greater iron needs than other diets, mainly because non-heme iron from plant-based foods is less bioavailable, and absorption is hindered by whole grains, legumes, and nuts due to their phytic acid content.

Vegans are also at risk of anemia due to a lack of heme iron. Iron-deficient anemia is the most common nutritional deficiency in the world, and both vegans and vegetarians are at higher risk of this condition. While plant foods contain a form of iron, it is called non-heme iron and it is much less absorbable by the body.

Furthermore, there is a risk of consuming too many carbohydrates on a vegan diet, especially since legumes are often consumed as a protein source but are very high in carbohydrates. Vegans may also replace the calories from protein sources with refined carbohydrates, including bread, crackers, and cookies. Over-consuming carbohydrates can lead to non-alcoholic fatty liver disease, blood sugar dysregulation, and other troublesome symptoms.

In conclusion, while some people may thrive on a vegan diet, it is considered an extreme diet because of the number of foods it excludes and the potential for nutritional deficiencies. It is not scientifically better than other diets and may lead to adverse health outcomes.

Lies and propaganda

Vegans have been accused of spreading misinformation about the health benefits of veganism and the health risks of consuming meat. However, these claims are often exaggerated and based on false assumptions. While it is true that meat can contribute to higher cholesterol levels and has been linked to cancer, there are also many benefits of meat consumption that are often left out of the equation.

For example, meat is a good source of certain nutrients, such as Vitamin B12 and Creatine, which are important for blood formation, brain function, and energy levels. Vegans may also have lower testosterone levels than their meat-eating counterparts. Additionally, vegan diets can be extremely restrictive and may lead to nutritional deficiencies, increased risk of depression, and even eating disorders.

Some people may claim that a vegan diet is the healthiest option, but this is not necessarily true. Carbohydrates, for instance, are important energy boosters, but if consumed in excess, they can have negative effects. Similarly, a low-carb, high-fat diet can be beneficial as long as the intake of fat is kept in check and is accompanied by proper nutrition and exercise.

It is important to note that the risks associated with vegan diets are often due to a lack of planning and supplementation. A well-planned vegan diet that includes a variety of whole foods, such as fruits, vegetables, legumes, grains, nuts, and seeds, can be healthy and nutritious. However, it requires careful planning to ensure all nutritional needs are met, and even then, some deficiencies may still occur.

In conclusion, while there may be some valid concerns about the health risks of vegan diets, it is important to separate fact from fiction. Veganism may not be the healthiest or most natural diet for humans, but that does not mean it is inherently terrible. However, it is essential to approach any extreme diet with caution and to prioritize getting all the necessary nutrients, whether through food or supplementation.

Lack of a health reason to avoid meat

There is a lack of health reasons to avoid meat, and some sources even suggest that veganism is a terrible idea because of this.

Firstly, meat provides essential nutrients that cannot be obtained from a vegan diet. For example, meat is a source of vitamin B12, which is important for the formation of blood and the function of the brain. Meat also contains creatine, which helps form an energy pool in cells. Avoiding meat can lead to a vitamin B12 deficiency, which can have irreversible health consequences.

Secondly, meat is a good source of protein and iron, which give you energy. While it is possible to obtain these nutrients from other sources, such as eggs, beans, nuts, and seeds, the body absorbs more iron from meat than from other foods. A vegan diet may, therefore, lead to fatigue and weakness.

Thirdly, a vegan diet is restrictive and can be difficult to follow. It requires careful planning to ensure that all nutritional needs are met, and even then, supplementation may be necessary. For example, vegans are often advised to take a high-quality vitamin B12 supplement.

Finally, some evidence suggests that meat consumption can have health benefits. For example, one study found that replacing just 1% of calories from animal proteins with plant proteins lowered the risk of developing type 2 diabetes by 18%. Additionally, meat can be a good source of lean protein, which has been shown to have a positive effect on satiety and weight management.

In conclusion, while there are some potential health risks associated with meat consumption, there is also a lack of compelling health reasons to avoid it altogether. A balanced diet that includes meat in moderation can be a healthy choice and may even provide some nutritional benefits that are difficult to obtain from a vegan diet.

Extreme and restrictive

Veganism is often regarded as an extreme and restrictive diet due to the exclusion of numerous food groups and the potential for nutritional deficiencies. This belief is supported by the notion that a vegan diet is challenging and may lead to health issues. Some people view veganism as an unnecessary restriction, believing that meat and other animal products are essential for optimal health.

The extreme nature of veganism is emphasised by those who argue that it excludes too many foods and that this restriction can lead to social isolation. The diet's limitations can make it challenging to obtain sufficient protein, specific vitamins, and minerals, leading to potential health consequences. For example, vegans are at a higher risk of developing a vitamin B12 deficiency, which can have irreversible health effects.

Additionally, the vegan diet is often associated with an increased risk of anaemia due to a lack of heme iron, which is more easily absorbed by the body than the non-heme iron found in plant-based sources. This can result in fatigue and is of particular concern for women of childbearing age.

Proponents of veganism may advocate for a strict exclusion of all animal products, including eggs, dairy, meat, fish, poultry, and even honey. This can be seen as extreme by those who believe that a more flexible or balanced approach to diet is preferable.

Furthermore, some individuals take veganism beyond diet and embrace it as a lifestyle, choosing to avoid purchasing or using any products containing animal-based ingredients, including clothing and personal care items. This can be seen as a restrictive lifestyle choice that significantly limits consumer options.

In conclusion, the perception of veganism as extreme and restrictive is influenced by the diet's exclusion of various food groups, the potential for nutritional deficiencies, and the social and lifestyle implications associated with avoiding all animal products.
