Nutritional challenges such as vitamin B12, iron, and omega-3 deficiencies, along with digestive discomfort and energy shortfalls, can make vegan diets difficult to sustain. Social and cultural pressures, including limited dining options, family traditions, and identity strain, also influence decisions to abandon strict veganism. Economic factors, reduced availability of vegan products, and scepticism toward ultra-processed plant-based foods further contribute to the shift away from the diet.

Vitamin B12 Deficiency Risks for Vegans
Vitamin B12 is primarily found in animal-derived foods, so those following a vegan diet are at higher risk of deficiency. Without adequate supplementation or consumption of fortified foods, low B12 levels can cause fatigue, weakness, and potentially serious neurological problems. Careful dietary planning and the use of supplements are essential to maintain healthy B12 status in vegan diets.
Iron Absorption Difficulties in Vegan Diets
Vegans rely on non-heme iron from plant foods, which the body absorbs less efficiently than heme iron from animal products. This reduced absorption can increase the risk of iron-deficiency anaemia, especially for women of childbearing age. Careful dietary planning, pairing iron-rich plants with vitamin C sources, or using supplements can help maintain healthy iron levels.
Omega-3 Deficiency Risks in Vegan Diets

Vegan diets typically lack direct sources of long-chain omega-3 fatty acids such as DHA and EPA, which support brain and heart function. While plant foods like flaxseed and chia provide alpha-linolenic acid (ALA), the body converts ALA to DHA and EPA inefficiently. This makes fortified foods or supplements a common strategy for meeting omega-3 needs on a vegan diet.
High Fibre Diets Can Trigger Digestive Discomfort
A rapid increase in fibre intake, common when switching to a vegan diet, can cause bloating, gas, and abdominal discomfort. Foods like legumes, whole grains, and fibrous vegetables are nutritious but can be challenging for the digestive system to process in large amounts. Gradually increasing fibre consumption and incorporating a variety of sources may help reduce these symptoms.
Hormonal Changes Linked to Some Vegan Diets
Anecdotal reports suggest that some women experience menstrual irregularities or hormonal shifts after adopting very low-fat or calorie-insufficient vegan diets. These changes may be related to nutrient intake and can sometimes improve with dietary adjustments or by reintroducing certain foods. Not all individuals experience these effects, and responses to dietary changes vary widely.
UK Study Finds Mycotoxins in All Tested Plant-Based Foods
A survey of plant-based meat alternatives and beverages sold in the UK found that all tested samples contained at least one mycotoxin, though levels were below EU guideline limits. While occasional consumption is unlikely to be harmful, researchers caution that long-term cumulative exposure could increase health risks. Mycotoxins are naturally occurring toxins from fungi that can contaminate grains, legumes, and seeds used in these products.
Protein Adequacy Challenges in Vegan Diets
Some vegans, particularly athletes, express concern about meeting protein needs through plant-based foods alone. While it is possible to obtain sufficient protein from sources like legumes, grains, and nuts, many rely heavily on protein powders or soy products to reach their targets. This reliance reflects cultural associations between protein intake, strength, and satiety, and highlights the planning required for adequate nutrition on a vegan diet.
Energy Deficits from Low-Calorie Vegan Diets
Some vegan diets, especially those focused on low-calorie density foods, can lead to unintentional energy deficits. This may result in fatigue, weight loss, and other symptoms if calorie needs are not met. Including calorie-dense plant foods such as nuts, seeds, avocados, and whole grains can help maintain adequate energy levels.
Social Dining Challenges for Vegans

Vegans often face limited menu options when eating out, making it difficult to find suitable meals. The need to repeatedly explain dietary restrictions to servers and companions can add to the stress, leading some to avoid social dining situations altogether. Over time, this can reduce participation in gatherings and impact social connections.
Non-Vegan Households Can Challenge Vegan Commitments
Sharing a home with non-vegan partners or family members can create ongoing challenges for those following a vegan diet. Differences in meal preparation, negotiating holiday menus, and navigating social expectations can add daily stress. Over time, this social pressure can contribute to individuals easing their dietary restrictions or abandoning veganism altogether.
Cultural Traditions Influence Dietary Choices
In cultures where animal-based dishes hold symbolic or traditional importance, strict veganism can create emotional distance from family and heritage. Declining cherished recipes or holiday meals may feel like severing ties to ancestral practices. To maintain cultural continuity, some individuals choose to reintroduce traditional animal-based foods into their diets.
Vegan Identity Pressure Can Lead to Burnout

For some individuals, veganism evolves beyond dietary choices into a core part of their identity. The expectation to consistently represent the movement without error can create significant psychological strain. Over time, this pressure may lead some to step away from the label, even if they continue to eat mostly plant-based foods.
Plant-Based Foods Often Perceived as Costlier
Surveys indicate that a significant portion of consumers believe plant-based products are more expensive than animal-based alternatives. This perception, combined with the higher price of specialty vegan items, can discourage purchases and contribute to higher overall grocery costs for those choosing plant-based diets.
Vegan Diets Require Careful Meal Planning
Following a vegan diet can demand significant planning to ensure all essential nutrients are included. Nutrients such as vitamin B12, iron, omega-3 fatty acids, calcium, and high-quality protein often require deliberate food choices or supplementation. For many, the time and effort involved in balancing these needs can make long-term adherence challenging.
Plant-Based Meat Sales Fell by 4% in 2024
According to the Good Food Institute, sales of plant-based products dropped by about 4% in 2024. Imitation meat and seafood experienced the steepest declines, falling roughly 12–13% from their 2021–2022 peak. Consumers cited high prices and concerns over heavy processing as key reasons for reduced purchases.
Major Chains Scale Back Vegan Menu Options
Several major restaurant chains, including Wagamama and Domino's, have reduced their vegan menu offerings in response to lower consumer demand. This shift reflects a broader trend in the food service industry, where initial enthusiasm for plant-based dishes has waned. Economic pressures and changing consumer preferences have led some businesses to focus on more popular menu items.
Ultra-Processed Vegan Foods Spark Scepticism

As plant-based products have surged in popularity, many vegan options now rely on ultra-processed ingredients. These items often feature long ingredient lists, industrial oils, flavour enhancers, and protein isolates, shifting the focus from whole, organic foods to convenience products. This change has led some to question whether modern veganism aligns with its original health-focused ideals.
