The term 'vegan' is broad, covering anyone who avoids animal products. However, within this umbrella, there is a spectrum of strictness, ranging from those who follow a purely plant-based diet to individuals who adhere to highly disciplined dietary restrictions and uncompromising ethical codes. To understand what the strictest vegan is, one must examine these various levels of commitment.
Fruitarianism: The Ultimate Dietary Extreme
Perhaps the most restrictive form of veganism purely from a dietary perspective is fruitarianism. As a subset of both veganism and raw foodism, this diet typically consists of 50–75% fruit, with some variations allowing for nuts and seeds. For some, the motivation is not just about health, but a desire to not harm any living thing, including plants, by only eating what falls or can be harvested without killing the plant.
What a Fruitarian Eats
A fruitarian diet revolves around the consumption of botanical fruits. This includes items that are often considered vegetables in a culinary context, such as tomatoes, cucumbers, peppers, and avocados. Other allowed foods include:
- Acid fruits: Citrus, cranberries, and pineapples.
- Subacid fruits: Sweet cherries, raspberries, and figs.
- Sweet fruits: Bananas, grapes, and melons.
- Oily fruits: Avocados, coconuts, and olives.
- Nuts and Seeds: These may be consumed in smaller quantities.
Significant Risks and Drawbacks
Due to its highly restrictive nature, fruitarianism carries a high risk of nutritional deficiencies and is not recommended by health experts. Notable risks include:
- Nutrient Deficiencies: Lack of protein, calcium, iron, zinc, B vitamins (especially B12), and essential fatty acids.
- Blood Sugar Imbalance: High natural sugar content can be problematic for individuals with blood sugar control issues.
- Tooth Decay: The high sugar and acid content of fruits can erode tooth enamel.
- Malnutrition: Severe restriction can lead to fatigue, muscle loss, and in extreme cases, severe malnutrition.
Raw Veganism: Uncooked and Unprocessed
A raw vegan diet combines the principles of veganism and raw foodism. It involves eating only unprocessed, raw, plant-based foods that have not been heated above a certain temperature (typically 104–118°F or 40–48°C). The philosophy is that heating food above this temperature destroys essential enzymes and nutrients.
Raw Vegan Food Principles
A raw vegan diet includes a wider range of foods than a fruitarian one. Approved items include:
- Fruits
- Vegetables
- Nuts and Seeds
- Sprouted grains and legumes
- Cold-pressed oils
- Fermented foods like sauerkraut
Considerations and Challenges
While less restrictive than fruitarianism, a raw vegan diet still requires careful planning to avoid nutritional gaps. Potential deficiencies include vitamin B12, vitamin D, iron, calcium, and omega-3 fatty acids. It can also be a challenge to consume enough calories and protein to sustain a high-energy lifestyle.
Beyond Diet: Ethical Veganism
For many, strictness isn't just about what they consume but how they live. Ethical veganism is a comprehensive lifestyle philosophy that seeks to exclude all forms of exploitation of and cruelty to animals as far as is possible and practicable. This goes far beyond diet alone.
The Ethical Vegan Code
An ethical vegan rejects all products that involve animal exploitation, including:
- Food: No meat, dairy, eggs, or honey.
- Clothing: No leather, wool, silk, or fur.
- Household Items: Avoid products tested on animals or containing animal-derived ingredients (e.g., tallow in soap).
- Entertainment: Reject zoos, circuses with animal acts, or exotic pet ownership.
Defining a Truly Strict Vegan
An individual could be a raw vegan, a fruitarian, or a standard plant-based eater. But an ethical vegan, regardless of their specific diet, embodies the strictest form of the vegan philosophy by rejecting all animal exploitation. A person who practices Ethical Fruitarianism could be considered the strictest form of vegan, combining the most restricted dietary practices with a comprehensive ethical code against all animal and plant harm.
A Comparison of Strict Vegan Diets
| Aspect | Fruitarianism | Raw Veganism | Ethical Veganism (Dietary Aspect) |
|---|---|---|---|
| Primary Food Source | 50–75% raw fruits | Unprocessed raw plant foods | All plant-based foods, cooked or raw |
| Excluded Foods | All animal products, most grains and vegetables | All animal products, cooked/processed foods | All animal products (meat, dairy, eggs, honey) |
| Cooking Methods | No cooking | No heating above 104–118°F | Standard vegan cooking, all temperature ranges |
| Flexibility | Extremely low | Low to moderate | High |
| Nutritional Risks | High (B12, protein, fat, iron) | Moderate (B12, D, iron, calcium) | Low (with careful planning) |
| Core Motivation | Health, ethics (non-harm to plants) | Health, preservation of enzymes | Ethics (animal welfare), health, environment |
Conclusion
Identifying what is the strictest vegan involves looking at both diet and lifestyle. While fruitarianism represents the most extreme level of dietary restriction, the encompassing philosophy of ethical veganism is arguably the strictest lifestyle commitment. Adherents of either extreme face significant nutritional challenges that require meticulous planning or supplementation to avoid health risks. For most people, a well-planned standard vegan diet offers the proven benefits of a plant-based lifestyle without the severe restrictions and associated dangers of its more extreme subsets.
