Understanding the cons of a vegan diet

The rise of veganism has sparked conversations about ethical eating, environmental sustainability, and personal well-being. While a vegan diet offers numerous benefits, it’s important to shed light on its potential drawbacks and challenges. This article will discuss the drawbacks of a vegan diet and provide strategies to effectively mitigate them.

What nutritional challenge do vegans face?

Embracing a vegan diet necessitates careful attention to nutrient intake. Certain vital nutrients, such as vitamin B12, omega-3 fatty acids (EPA and DHA), iron, calcium, zinc, and vitamin D, are more abundant in animal-derived foods. Insufficient intake of these nutrients can lead to deficiencies, impacting energy levels, muscle health, cognitive function, and immune system resilience. While vegan-friendly sources and supplements are available, conscientious planning is crucial to avoid potential health risks.

Vitamin B12

Vitamin B12 is primarily found in animal products. Vegans are at a higher risk of deficiency because plant-based foods typically don’t contain sufficient amounts of this vitamin. Vitamin B12 is essential for nerve function, DNA synthesis, and red blood cell production. Vegans should consider taking a vitamin B12 supplement or consuming fortified foods like plant-based milk, breakfast cereals, or nutritional yeast.

Omega-3 Fatty Acids

Omega-3 fatty acids is important for our bodies because it supports heart health, brain function, reducing inflammation, and maintaining overall well-being. EPA and DHA in particular are two omega-3 commonly found in fatty fish. ALA, another form of omega-3, is present in plant sources like flaxseeds, chia seeds, walnuts, and hemp seeds. However, the conversion of ALA to EPA and DHA in the body is limited. Vegans might consider algae-based supplements to ensure an adequate intake of these important fatty acids.


Plant-based sources of iron (non-heme iron) are not as readily absorbed by the body as heme iron from animal sources.
To enhance iron absorption, vegans can consume vitamin C-rich foods (e.g., citrus fruits, bell peppers) alongside iron-rich foods. Cooking in cast iron cookware can also help increase iron content in meals.


While many plant-based foods provide calcium (e.g., fortified plant milks, leafy greens, tofu), vegans may need to pay closer attention to their calcium intake, especially if they avoid fortified foods and dairy alternatives. Adequate vitamin D intake and weight-bearing exercises can also support calcium absorption and bone health.


While plant-based foods do contain zinc, its bioavailability can be hindered by phytates, which impede absorption. To enhance zinc intake, incorporating zinc-rich foods such as legumes, whole grains, nuts, and seeds into your diet is essential. Food preparation methods, such as soaking, sprouting and fermenting foods, can help enhance zinc absorption.

Are plant-based diets poorer in protein quality?

Not all proteins are equal Since plant based protein has lower absorptivity you might need to consume more protein to match the nutrients you get from meat

Proteins, the building blocks of life, come in various forms, each with its own unique quality and nutritional fingerprint. These qualities are a culmination of their amino acid composition and bioavailability, two factors that play a pivotal role in determining how effectively our bodies can harness their benefits. Proteins from animal sources earn the title of “high-quality” due to their abundant presence of all nine essential amino acids (EAAs) and superior bioavailability. This rich amino acid profile, combined with the ease with which our bodies absorb these essential nutrients, highlights the nutritional benefits of animal-derived proteins.

While plant proteins offer a bounty of nourishment, they often exhibit variations in their essential amino acid content. For instance, some legumes, may be deficient in certain EAAs such as methionine, cysteine, and tryptophan.

Furthermore, the bioavailability of plant proteins can be influenced by the structural complexities of these proteins themselves. The presence of tannins and phytic acid can limit the ease with which our bodies extract nutrients from plant sources. This reduces the overall bioavailability of essential amino acids. Even dietary fiber, so celebrated for its health benefits, can sometimes inadvertently hinder protein digestibility.

In essence, the nutritional landscape of proteins reveals a fascinating interplay between animal and plant sources. While animal proteins dazzle with their high-quality composition and readily absorbable nature, plant proteins showcase their unique characteristics, sometimes necessitating thoughtful combinations and preparation techniques to unlock their full potential. As we navigate the culinary world with these insights, we embrace a holistic understanding of protein quality, recognising that each source brings its own nutrient-rich offerings to the table.

Does plant protein have a complete amino acid profile?

Adequate protein consumption is a concern for many vegans, as plant-based protein sources may lack certain essential amino acids. Crafting a balanced protein profile demands careful selection and combination of various plant foods. Without proper planning, vegans might find it challenging to meet their protein requirements, potentially hindering muscle maintenance and overall vitality. Consuming a variety of protein sources such as legumes, tofu, tempeh, seitan, quinoa, and nuts can help meet protein needs.

One common misconception surrounding plant-based diets is the notion of “incomplete proteins.” Unlike animal-based protein sources, some plants may lack one or more essential amino acids, which are the building blocks of protein. However, modern nutritional understanding allows vegans to consume a complete amino acid profile. By thoughtfully pairing different plant sources, you can effortlessly harness the full spectrum of essential amino acids required for robust protein synthesis.

Adequate protein consumption is essential for our health. It promotes muscle health, enabling you to develop strength and perform daily tasks. Inadequate protein intake can lead to gradual muscle mass loss, potentially causing muscle and joint deconditioning. When this occurs, you may experience back pain, neck pain, or even slipped disc. Over time, this may lead to the development of sarcopenia, a condition characterised by loss of muscle mass and diminished overall physical function.

Veganism can be expensive!

A vegan lifestyle can be expensive According to surveys done in the United States vegans spend almost 50 more on grocery bills

The perception that veganism is expensive is often linked to the availability and cost of specialty products. Dairy alternatives, plant-based meats, and other innovative substitutes designed to mimic animal-derived products tend to carry higher price tags due to production processes, research, and development. While these options can add variety to a vegan diet, they are not essential and can be supplemented with more budget-friendly whole foods.

he association of veganism with organic, locally sourced, and premium products contributes to its perceived cost. Opting for these food items can indeed elevate the grocery bill. However, it’s essential to recognise that a vegan diet can be achieved with a range of budget-friendly options, including conventional produce and pantry staples.

The decision to supplement can influence the perceived cost of veganism. Quality supplements, especially those sourced from whole-food ingredients and produced with sustainable practices, can come with a price tag. This can be a concern, particularly for individuals who are looking to maintain a budget-friendly vegan lifestyle. Viewing supplementation as a long-term investment in health is a prudent approach. Adequate intake of essential nutrients is vital for your well-being and can contribute to a reduced risk of chronic diseases. By prioritising necessary supplements, individuals can make informed choices that align with their health goals.

Eating out and and social events may become more complex

Dining out, gathering with friends, and embarking on adventures are all part of the rich tapestry of life. For vegans, however, these seemingly ordinary activities can sometimes present unique challenges, especially in regions where plant-based options are limited. The art of gracefully navigating these social situations while honoring your dietary choices is an essential aspect of the vegan journey.

When planning to dine out or attend a social gathering, consider reaching out to the hosts or the restaurant in advance. Many establishments are becoming increasingly accommodating to dietary preferences and restrictions, including veganism. Communicating your needs and preferences can pave the way for a smoother experience.

While it’s wonderful to find vegan options, sometimes you might encounter limitations. This is where flexibility comes into play. If there are no explicit vegan choices on the menu, consider customising existing dishes by omitting animal products or substituting them with plant-based alternatives. Most restaurants are willing to accommodate requests when possible.
