The Pros and Cons of a Vegan Lifestyle

 A vegan lifestyle—often praised for its potential health benefits and environmental advantages—invites us to reconsider how we eat, live, and impact the planet. But, as with any choice, there’s more to the story. Here’s a deep dive into what adopting veganism truly entails.

About a decade ago, my best friend Katie decided to embrace Veganuary, vowing to eliminate all animal products from her diet for the month of January. That meant no meat, seafood, dairy, or any ingredients derived from animals. I had questions, of course. Was she aware that being vegan would mean giving up pizza? Wait, are Oreos vegan? And, would she let me borrow her leather boots? What began as a month-long experiment blossomed into a lifestyle; Katie has maintained a vegan diet ever since.

Many are drawn to veganism for personal health benefits or ethical reasons, and for those contemplating the shift, it’s crucial to understand both the upsides and downsides.

What Defines a Vegan Diet?

At its core, a vegan diet excludes any and all animal products, centering around plants like vegetables, fruits, whole grains, legumes, beans, nuts, and seeds. This approach strictly avoids:

  • Eggs
  • Dairy products
  • Honey

Plant-based foods are inherently high in fiber, packed with essential minerals and vitamins, and are typically low in calories and saturated fats. But with the benefits come some sacrifices, particularly of nutrients traditionally sourced from animal-based foods.

Vegan vs. Vegetarian: A Noteworthy Distinction

Think of vegans as the rigorous professors and vegetarians as the relaxed substitutes; both avoid meat, yet vegetarians often incorporate other animal products into their diets, like dairy and eggs. For instance, lacto-ovo vegetarians consume both dairy and eggs, while vegans strictly refrain from all animal-based foods.

Health Benefits of a Vegan Diet

Ample research connects veganism with a reduced risk of serious health conditions, including:

  • Type 2 diabetes
  • Cardiovascular disease
  • Heart disease
  • Cancer
  • Hypertension
  • Non-alcoholic fatty liver disease

A vegan diet can also help lower LDL cholesterol levels—"bad" cholesterol—and encourage weight loss. In a study involving identical twins, the twin adhering to a healthy vegan diet for eight weeks saw a 15% decrease in LDL levels and a 3% reduction in body weight compared to their omnivorous sibling.

Beyond individual health, the global implications of veganism are staggering. A study in the Proceedings of the National Academy of Sciences suggests that a worldwide transition to vegan diets could prevent an estimated 129 million deaths and save trillions in healthcare costs by 2050.

Yet, veganism isn’t without its challenges. Nutritional deficiencies are possible, particularly with B12, calcium, and vitamin D, which are commonly derived from animal products. Without careful planning, the vegan diet may also increase the risk of bone fractures, bleeding issues, and adverse outcomes in pregnancy due to insufficient intake of these nutrients.

Environmental Impact of Veganism

Could going vegan help "save the planet"? Science suggests it could. Animal farming, particularly cattle raising, generates significant methane and carbon dioxide emissions—greenhouse gases that contribute to climate change. Livestock production demands enormous resources like water and land, causing much higher environmental strain than plant-based agriculture. A vegan’s carbon footprint is therefore far smaller than that of a meat-eater.

The Cost of a Vegan Diet

While one might assume veganism to be expensive, studies across 150 countries reveal the opposite. In fact, diets rich in plants are generally more affordable than those involving animal products and processed foods. Veganism can reduce food costs by roughly one-third.

However, specialty vegan items like fortified foods, meat substitutes, and supplements can inflate grocery bills. So, while basics like beans and grains remain budget-friendly, niche vegan products might add to the cost.

Challenges of Adopting a Vegan Lifestyle

For those new to veganism, the transition isn’t always smooth. Dining out may present limited options, especially at non-vegan-friendly venues. Yes, there’s usually a salad on the menu—but is lettuce really a satisfying meal?

Grocery shopping can be equally daunting. Ingredient labels often require close inspection (looking at you, gelatin), and without proper planning, maintaining a balanced vegan diet might feel overwhelming. Additionally, access to vegan-friendly foods is not universal. In some areas, availability can be sparse, pushing vegans toward processed snacks like chips and cookies, which may be plant-based but lack nutritional balance.

All said, the journey into veganism is highly personal and demands thoughtful planning. Consult a healthcare provider if you’re considering this path, as they can help ensure you meet your nutritional needs and find a diet that aligns with your health goals.
