Veganism: A Lifestyle Choice, Not A Mandate

Veganism isn't for everyone, and there are several reasons why. Firstly, a vegan diet may not be suitable for everyone due to dietary restrictions or pre-existing health conditions. For instance, some people may not have the genetic disposition to maintain healthy bodily functions without certain nutrients. Genetic factors such as vitamin A conversion, gut microbiome makeup, and amylase levels can impact how well a person responds to a vegan diet. Additionally, a vegan diet can be restrictive and time-consuming, making it challenging for those with busy schedules or limited access to vegan food options. Furthermore, a vegan diet may not be affordable for everyone, as vegan food items tend to be more expensive than their non-vegan counterparts. While veganism has its benefits, it is important to recognize that it may not be the best choice for everyone, and individuals should make informed decisions about their dietary choices based on their personal circumstances and health needs.

Genetic factors, such as vitamin A conversion, can make it difficult for some to maintain healthy bodily functions without certain nutrients

Genetic factors, such as vitamin A conversion, can make it difficult for some people to maintain healthy bodily functions without certain nutrients. Vitamin A is a fat-soluble vitamin that plays a crucial role in maintaining vision, supporting the immune system, promoting healthy skin, assisting in normal growth and development, and is vital for reproductive function. While vitamin A is typically associated with animal-based foods, plants also contain precursors that the body can convert into vitamin A, the most well-known of which is beta-carotene.

However, the conversion of beta-carotene into vitamin A relies on the enzyme beta-carotene-15,15'-monooxygenase (BCMO1). Several gene mutations can reduce the activity of this enzyme, impacting the body's ability to convert beta-carotene efficiently. For example, the R267S and A379V polymorphisms in the BCMO1 gene can collectively reduce beta-carotene conversion by 69%, while the less common T170M mutation can reduce conversion by about 90% in people who carry two copies of the gene. These genetic variations are relatively common, with about 45% of the population classified as "low responders" to beta-carotene conversion.

The impact of these gene mutations becomes more apparent when individuals adopt a vegan diet. Animal-based foods provide vitamin A in the form of retinoids, which do not require BCMO1 conversion. In contrast, a vegan diet relies solely on plant-based sources of beta-carotene. For individuals with reduced BCMO1 activity, consuming carrots or sweet potatoes may not provide sufficient vitamin A to maintain optimal health. This can lead to vitamin A deficiency and associated health issues such as thyroid dysfunction, night blindness, impaired immunity, and problems with tooth enamel.

The consequences of vitamin A deficiency are not limited to physical health. Research suggests that vitamin A plays a role in mental health as well. A study comparing meat-eaters and meat-abstainers found that meat-abstainers had a higher prevalence of unipolar depressive and anxiety disorders. Additionally, vegetarian and vegan women may be more prone to disordered eating attitudes and practices, such as orthorexia nervosa, which involves a fixation on health-conscious eating behavior and self-imposed restrictions.

In summary, genetic factors influencing vitamin A conversion can impact an individual's ability to maintain healthy bodily functions on a vegan diet. The reduced conversion of beta-carotene to vitamin A can lead to vitamin A deficiency, affecting both physical and mental health. While a vegan diet can be healthy for some, it is important to consider individual genetic variations and ensure adequate nutrient intake to maintain overall well-being.

It can be a precursor to disordered or obsessive eating, which may have health consequences

Veganism can be a restrictive diet that cuts out many foods, which may be difficult for those at risk of developing eating disorders or who already have an unhealthy relationship with food. Veganism can be a precursor to disordered eating, which may have health consequences.

It is important that those on a vegan diet get the same nutrients as non-vegans and meet their personal caloric needs. While some foods, such as Oreos and potato chips, are technically vegan, they do not have the same nutritional value as fruits, vegetables, and whole grain breads. In some cases, veganism can lead to an even more unhealthy diet, as it is often easier to pick up a bag of Doritos than to prepare tofu or chop vegetables.

The vegan diet is time-consuming and inconvenient, and this is often the main reason veganism is not realistic for some. Many people do not realise the amount of time, effort, and money that goes into meal-prepping before adopting a vegan lifestyle. Additionally, vegan food typically comes with a heftier price tag and may cause your grocery bill to skyrocket.

It is still possible for non-vegans to live a healthy lifestyle by choosing nutrient-rich, diverse foods and choosing organic foods over processed ones.

It is time-consuming and expensive, and therefore not realistic for everyone

Veganism is a time-consuming and expensive commitment that is not realistic for everyone. It requires a lot of time, effort, and money for meal-prepping, and the price of vegan food can make your grocery bill skyrocket. For example, a single portion of Amy’s vegan macaroni and soy cheese costs $4.69, whereas the version with real cheese costs $3.69. Similarly, a 16oz container of coconut milk yogurt costs $5.49, while a container of Chobani yogurt costs $3.99.

The time and money required to maintain a vegan lifestyle can be a huge downfall and is often the main reason why veganism is not realistic for some. Many people do not realize the amount of time, effort, and money that goes into meal-prepping before adopting a vegan lifestyle.

Veganism is an expensive and tedious commitment that many people, such as college students, low-income individuals, or those who work multiple jobs, cannot realistically maintain.

It can be very restrictive, which could cause a deficiency in important nutrients

A vegan diet can be very restrictive, which could cause a deficiency in important nutrients. While a vegan diet can be nutritious and healthy, it is very restrictive in terms of food choices. Vegans must exclude all animal products, including meat, poultry, fish, dairy, eggs, and honey. This restriction can make it challenging to plan a balanced diet and ensure adequate nutrient intake.

One of the main concerns with a vegan diet is vitamin B12 deficiency. Vitamin B12 is found primarily in animal-based foods such as meat, poultry, and eggs. Vegans who do not supplement their diet with vitamin B12 or consume fortified foods may be at risk of deficiency, which can lead to neurologic and haematologic problems.

Another nutrient of concern is protein. Plant-based proteins are generally less digestible than animal proteins, and processing methods can further reduce their digestibility. As a result, vegans may struggle to meet their protein requirements, particularly if they do not consume a variety of plant-based protein sources.

In addition to protein, other nutrients that may be lacking in a vegan diet include calcium, omega-3 fatty acids, zinc, vitamin D, and iron. These nutrients are essential for maintaining overall health and preventing deficiencies that can lead to health issues.

The restrictiveness of a vegan diet can also make it challenging for those at risk of developing eating disorders or those who already have unhealthy relationships with food. The elimination of many food groups can lead to an even more unhealthy diet, as it may be easier to reach for less nutritious vegan options like chips or cookies instead of preparing tofu or chopping vegetables.

Furthermore, the time and effort required to plan and prepare vegan meals can be a significant inconvenience for some individuals. The cost of vegan food options is also typically higher, which may make it difficult for individuals on a budget to maintain a vegan diet.

While a vegan diet can be healthy and nutritious, its restrictive nature can lead to potential nutrient deficiencies if not carefully planned. It is important for individuals considering a vegan diet to ensure they are meeting their nutritional needs through a variety of plant-based sources or supplements.

It may not be suitable for those with pre-existing health conditions

Why a Vegan Diet May Not Be Suitable for Those With Pre-Existing Health Conditions

A vegan diet may not be suitable for everyone, and individuals with pre-existing health conditions should approach it with caution. While a vegan diet can be nutritious and ethical, it also has the potential to exacerbate certain health issues and create nutritional deficiencies.

Vitamin A Conversion

Vitamin A is essential for maintaining vision, supporting the immune system, and promoting healthy skin and growth. While plant foods contain beta carotene, a precursor to vitamin A, genetic factors can impact the body's ability to convert it effectively. Certain gene mutations can reduce the activity of the BCMO1 enzyme, which is responsible for converting beta carotene into vitamin A. As a result, those with these mutations may not be able to obtain sufficient vitamin A from plant sources, leading to potential deficiencies and associated health issues.

Gut Microbiome and Vitamin K2

The gut microbiome plays a crucial role in synthesizing specific nutrients, and some microbial communities may be more conducive to a vegan diet than others. Certain bacteria in the gut are responsible for synthesizing vitamin K2, which is important for skeletal health, insulin sensitivity, and cancer prevention. However, factors such as antibiotic usage, genetics, and environment can impact the levels of these bacteria, leading to potential vitamin K2 deficiencies in those following a vegan diet.

Amylase and Starch Tolerance

Amylase is an enzyme found in human saliva that aids in the digestion of starch molecules. Genetic factors influence amylase levels, and individuals with low amylase production may struggle to metabolize starchy foods effectively, leading to blood sugar spikes and an increased risk of metabolic syndrome and obesity. A vegan diet centered on starchy foods, such as grains, legumes, and tubers, may exacerbate these issues for individuals with low amylase production.

PEMT Activity and Choline

Choline is an essential nutrient involved in various bodily functions, including metabolism, brain health, and lipid transport. While plant foods contain choline, animal products tend to have higher amounts. Additionally, common mutations in folate pathways or the PEMT gene can increase choline requirements. As a result, a vegan diet may not provide sufficient choline for individuals with these mutations, leading to potential health issues such as muscle damage, cognitive problems, and heart disease.

Other Considerations

Vegan diets can also impact calcium, vitamin D, vitamin B12, zinc, and iron levels. These deficiencies can lead to nervous system impairments, skeletal issues, immune system impairments, and an increased risk of fractures. Pregnant and breastfeeding women, as well as children and adolescents, may be particularly vulnerable to the potential negative effects of a vegan diet and should consult with a healthcare professional before making any significant dietary changes.

In conclusion, while a vegan diet can be a healthy and ethical choice for some, it may not be suitable for everyone. Individuals with pre-existing health conditions or specific genetic factors should carefully consider their ability to maintain healthy bodily functions on a vegan diet and consult with a healthcare professional to ensure their nutritional needs are met.
