Vegan Vs. Omnivore: Which Diet Is More Destructive?

The vegan diet has been a topic of debate for its supposed health benefits, but it is not without its drawbacks. While it may be better for heart health, it can also lead to nutritional deficiencies and other health problems. On the other hand, the omnivorous diet has been linked to an increased risk of certain cancers and other health issues. So, which diet is more destructive? The answer may lie in moderation and balance, with a plant-forward omnivorous diet being the most sustainable and healthy option.

Nutritional deficiencies in vegan diets

A vegan diet, while often promoted as being good for heart health, may cause nutritional deficiencies and lead to negative health consequences. A review published in the medical journal *Progress in Cardiovascular Diseases* found that a vegan diet may lead to nutritional deficiencies in vitamin B12, omega-3, calcium, zinc, iron, magnesium, and high-quality protein. These deficiencies have been linked to an increased risk of certain types of cancer, stroke, bone fractures, preterm birth, and failure to thrive.

A Stanford study, featured in the Netflix documentary, *You Are What You Eat: A Twin Experiment*, found that vegan participants were not able to gain lean muscle mass as easily as omnivores. They also had lower intakes of protein and vitamin B12, and reported lower satisfaction with their diet.

• Vitamin B12: This nutrient is essential for developing red blood cells and maintaining nerves and normal brain function. It is almost exclusively found in animal-sourced foods such as fish, meat, dairy products, and eggs. Vegans who do not take supplements are at a higher risk of vitamin B12 deficiency, which can lead to impaired brain function, neurological and psychiatric disorders, and anemia.
• Creatine: Creatine is a molecule found in animal foods and plays a role in muscle and brain function. It is not essential in the diet as it can be produced by the liver, but vegetarians and vegans tend to have lower amounts in their muscles.
• Carnosine: Carnosine is an antioxidant that is concentrated in the muscles and brain and is important for muscle function. It is only found in animal-based foods, but it is considered non-essential as the body can form it from the amino acids histidine and beta-alanine.
• Vitamin D3: Vitamin D is essential for various functions in the body, and while it can be produced by the skin when exposed to sunlight, those with limited sun exposure may need to get it from food or supplements. The best sources of vitamin D3 are fatty fish and egg yolks, so vegetarians and vegans may be at a higher risk of deficiency.
• Docosahexaenoic acid (DHA): DHA is an essential omega-3 fatty acid that is important for normal brain development and function. It is mainly found in fatty fish, fish oil, and certain types of microalgae. Vegetarians and vegans often have lower levels of DHA than meat-eaters.
• Heme iron: Heme iron is a type of iron found only in meat, especially red meat, and is much better absorbed than non-heme iron, which is found in plant foods. Vegetarians and vegans are more prone to anemia due to the lower absorption rate of non-heme iron.
• Taurine: Taurine is a sulfur compound found in various body tissues, including the brain, heart, and kidneys. It is found only in animal-sourced foods but is not considered essential as the body produces small amounts.

While a vegan diet can offer many health benefits, it is important to be aware of these potential nutritional deficiencies and consider supplementation or a more flexible approach to ensure adequate nutrient intake.

Health problems caused by vegan diets

Veganism is often touted as a healthy way of eating, but it is not without its drawbacks. While vegan diets can be beneficial for heart health, they can also lead to nutritional deficiencies and other health issues. Here are some of the health problems that can be caused by following a vegan diet:

Nutritional Deficiencies

One of the biggest concerns with a vegan diet is the risk of nutritional deficiencies. Vegan diets tend to be lower in certain key nutrients, including:

• Vitamin B12: Found only in animal foods, vitamin B12 is essential for preventing irreversible health conditions. Vegans are at a high risk of developing a deficiency.
• Omega-3: A lack of omega-3 fatty acids from fish or fish oils can increase the risk of depression and affect fetal brain development in pregnant women.
• Calcium: Dairy-free, vegan diets often provide less calcium than dairy products. This can increase the risk of bone fractures over time.
• Zinc: The high consumption of plant foods containing phytic acid in a vegan diet may inhibit the body's ability to absorb zinc, leading to a deficiency.
• Iron: Vegans are at a higher risk of iron-deficient anemia, the most common nutritional deficiency worldwide. Plant sources of iron (non-heme iron) are less easily absorbed by the body.
• Iodine: Without seafood, vegans may not get enough iodine, leading to hypothyroidism and other health issues.

Other Health Problems

In addition to nutritional deficiencies, other health problems have been observed in people following strict vegan diets, including:

• Hair loss
• Weak bones
• Muscle wasting
• Skin rashes
• Hypothyroidism
• Anemia
• Higher rates of depression and anxiety
• Increased risk of certain types of cancer, stroke, and preterm birth

Extreme Diet and Restriction

A vegan diet is considered extreme due to the number of restricted food groups, and it can be challenging to ensure adequate nutrient intake. This restriction can also lead to orthorexia, an eating disorder characterized by an obsession with healthy eating patterns and restrictive diets.

Weight Loss and Blood Sugar Swings

Vegan diets tend to be lower in protein and can cause blood sugar swings. They may also lead to overconsumption of carbohydrates, especially if legumes are the primary protein source. This can result in non-alcoholic fatty liver disease and blood sugar regulation issues.

In conclusion, while a vegan diet may offer some health benefits, it is not without its risks. It is important to carefully plan a vegan diet to ensure adequate nutrient intake and avoid potential health problems.

Environmental impact of vegan and omnivorous diets

The human body is adaptable to an omnivorous diet, but the rise of veganism has sparked debates about its health and environmental effects. This article will explore the environmental impact of vegan and omnivorous diets, examining their pros and cons to determine which is more ecologically sustainable.

Environmental Impact of Vegan Diets

Veganism has gained popularity due to its perceived health and environmental benefits. A vegan diet can help lower LDL cholesterol and improve heart health. However, it may also lead to nutritional deficiencies, including vitamins B12, D, omega-3, calcium, zinc, and high-quality proteins. To compensate, vegans may need to rely on intensive monocropping, which can have detrimental effects on the environment, such as deforestation and loss of biodiversity.

Environmental Impact of Omnivorous Diets

Omnivorous diets, when balanced and paired with physical activity, can provide various health benefits. They offer quality complete proteins that are easily absorbed and are a good source of vitamin B12, zinc, vitamin D, and omega-3 fatty acids. However, they can also increase the intake of saturated fats and cholesterol, contributing to higher LDL cholesterol levels. Additionally, intensive animal farming and meat production have been associated with significant environmental impacts, including greenhouse gas emissions, land degradation, and water consumption.

Comparison of Environmental Impacts

Both vegan and omnivorous diets have unique environmental impacts. While vegan diets may reduce the carbon footprint associated with meat production, they can also contribute to intensive crop production and monocropping, leading to soil degradation and biodiversity loss. On the other hand, omnivorous diets, especially those with high meat consumption, have been linked to increased greenhouse gas emissions and land degradation due to animal farming.

In conclusion, both vegan and omnivorous diets have their advantages and disadvantages regarding environmental sustainability. A vegan diet may reduce the environmental impact of meat production but may contribute to intensive crop production. In contrast, an omnivorous diet provides a diverse range of nutrients but can have higher environmental costs due to animal farming. Ultimately, the most ecologically sustainable diet may lie in moderation and balance, incorporating elements of both vegan and omnivorous approaches while minimizing overconsumption and promoting sustainable agricultural practices.
