What is a 90% Vegan Diet?

5 min read

According to a 2024 survey, 19% of South Africans claimed to follow a flexitarian diet, a pattern of eating that is similar to what is known as a 90% vegan diet. This adaptable eating style prioritizes plant-based foods, such as fruits, vegetables, grains, and legumes, while still allowing for a small, occasional inclusion of meat, dairy, or eggs. The focus is on a plant-forward approach rather than strict adherence, providing a path to better health and sustainability without the rigidity of a 100% vegan lifestyle.

Quick Summary

This article explores the principles of a 90% vegan diet, detailing how this flexible eating style works and what foods are prioritized. It covers the health benefits, key nutritional considerations, and practical strategies for transitioning.

Understanding the 90% Vegan Philosophy

At its core, a 90% vegan diet is a form of flexible eating, akin to a flexitarian or semi-vegetarian diet. The '90%' aspect refers to consuming plant-based foods the vast majority of the time, with animal products making up the remaining 10% or less of one's diet. This approach differs from full veganism, which strictly avoids all animal products, by acknowledging that occasional consumption can make the diet more sustainable and realistic for many people. Instead of aiming for perfection, the goal is to significantly reduce the environmental and health impacts associated with a diet heavy in animal products.

This style of eating encourages a shift in mindset—from what you can't eat to what you can eat, focusing on a wide and colorful variety of plant-based options. It allows for flexibility, such as enjoying a specific non-vegan meal at a social gathering, dining out with limited vegan options, or simply indulging in a favorite dish on rare occasions without guilt. This moderation can prevent the feeling of restriction that leads some people to abandon dietary changes entirely. The emphasis is on wholesome, minimally processed plant foods, while viewing animal products as an accent rather than the main component of meals.

Potential Health Benefits of a Mostly Vegan Approach

Embracing a plant-predominant diet can lead to numerous health improvements. Research has linked plant-based eating patterns with a reduced risk of several chronic diseases. By focusing on fruits, vegetables, and whole grains, a 90% vegan diet can be naturally low in saturated fat and cholesterol.

  • Cardiovascular Health: Plant-based diets are associated with lower blood pressure, reduced cholesterol levels, and a decreased risk of heart disease.
  • Weight Management: The high fiber content and lower energy density of plant foods can promote satiety and aid in weight loss. Studies show that those following plant-based diets tend to have a lower body mass index (BMI).
  • Diabetes Management: A plant-based diet can improve insulin sensitivity and lower the risk of developing type 2 diabetes.
  • Cancer Prevention: Increased consumption of fruits and vegetables, rich in antioxidants and vitamins, has been linked to a reduced risk of certain cancers.
  • Improved Gut Health: The high fiber in plant foods promotes a healthy gut microbiome by feeding beneficial bacteria, which in turn can reduce inflammation.

How to Structure Your 90% Vegan Diet

Transitioning to a 90% vegan diet can be a gradual and rewarding process. The key is to make mindful choices and prioritize plant-based options most of the time.

  1. Start with Meatless Days: Designate specific days of the week, like 'Meatless Monday,' to be 100% plant-based. As you become more comfortable, you can increase the frequency.
  2. Focus on Whole Foods: Build your meals around whole plant foods such as legumes (beans, lentils), whole grains (quinoa, brown rice), nuts, seeds, fruits, and vegetables.
  3. Explore Plant-Based Proteins: Experiment with diverse plant protein sources like tofu, tempeh, lentils, and chickpeas. They offer versatility and can easily replace animal proteins in many dishes.
  4. Gradually Reduce Animal Products: Instead of eliminating animal products all at once, consciously reduce their portion sizes. Treat meat, dairy, and eggs as occasional additions rather than the main event.
  5. Master Vegan Substitutions: Learn to replace animal products with plant-based alternatives in your favorite recipes. For instance, swap cow's milk for fortified plant milks (soy, almond, oat) and use nutritional yeast for a cheesy flavor.
  6. Meal Planning: Prepare plant-based meals ahead of time to make adherence easier, especially on busy days. Having nutritious options readily available can prevent last-minute decisions that compromise your goals.

Nutritional Considerations for a Mostly Vegan Diet

While a 90% vegan diet has many benefits, it's important to be mindful of certain nutrients, especially if you move closer to a 100% plant-based intake.

  • Vitamin B12: Primarily found in animal products, B12 is crucial for nerve function and red blood cell production. Fortified foods or a supplement may be necessary.
  • Iron: The non-heme iron found in plants is less easily absorbed than the heme iron in meat. Combining iron-rich plant foods (e.g., lentils, dark leafy greens) with a source of vitamin C can improve absorption.
  • Omega-3 Fatty Acids: While some plant sources exist (chia seeds, walnuts), those on a mostly vegan diet should ensure adequate intake.
  • Calcium and Vitamin D: These are essential for bone health. Good plant sources include fortified plant milks, tofu with added calcium, and leafy greens. Sunlight exposure and fortified foods can help with vitamin D intake.
  • Protein: While often a concern, a varied plant-based diet provides sufficient protein. Legumes, nuts, seeds, and whole grains are excellent sources.

90% Vegan vs. Flexitarian vs. Vegan

This comparison table helps clarify the differences between common plant-forward eating patterns.

Feature 90% Vegan Flexitarian Vegan
Primary Focus Plant-based, with flexibility Mostly plant-based, some meat Exclusively plant-based
Animal Products Allows occasional, limited animal products Allows meat, fish, and dairy in moderation Excludes all animal products (meat, fish, dairy, eggs)
Motivations Health, environmental, animal welfare, personal balance Health, environment, ethical reasons, flexibility Ethical, environmental, health
Strictness Moderate and self-defined Variable, often more lenient Strict adherence, no exceptions
Ease of Transition High, gradual reduction High, allows for flexibility Lower, requires full elimination
Nutritional Risks Lower risk if planned, minimal risk with occasional animal products Low risk if well-planned Higher risk of B12 and other deficiencies if not well-planned and supplemented

Conclusion

A 90% vegan diet offers a realistic and accessible entry point into plant-based eating, providing significant health and environmental benefits without the rigid constraints of a 100% vegan lifestyle. By prioritizing whole plant foods and being mindful of nutrient intake, individuals can experience better health outcomes, including a lower risk of heart disease, diabetes, and certain cancers. The flexibility of this approach makes it a sustainable choice for many, fostering a positive relationship with food rather than one of restriction. Whether as a long-term strategy or a stepping stone toward a fully vegan diet, a 90% vegan eating pattern is a powerful way to make healthier, more conscious food choices.

Frequently Asked Questions

A 90% vegan diet is a specific form of flexitarianism. Both focus on mostly plant-based eating with moderate animal product consumption. The '90%' specifies a higher proportion of vegan foods, whereas flexitarianism is a broader term encompassing various levels of meat and dairy reduction.

Yes, a well-planned 90% vegan diet can be nutritionally complete. The small allowance for animal products can help address nutrients that can be harder to obtain on a fully vegan diet, such as Vitamin B12. As with any diet, planning and variety are key to ensuring sufficient intake of all nutrients.

Since Vitamin B12 is found almost exclusively in animal products, those on a mostly vegan diet should consume fortified foods (like some plant milks and cereals) and/or a supplement. The occasional inclusion of animal products in a 90% vegan diet can also help, but supplementation is a reliable safeguard.

Yes, it can. The high fiber content in plant-based foods tends to promote a feeling of fullness, and these foods often have a lower calorie density compared to animal products. This can help with weight management, though overall calorie intake and exercise are also important factors.

Excellent sources of plant protein include legumes (beans, lentils), tofu, tempeh, seitan, nuts, seeds, and whole grains. Consuming a variety of these throughout the day helps ensure a complete amino acid profile.

By significantly reducing consumption of animal products, a 90% vegan diet helps lower your environmental footprint. Animal agriculture contributes to greenhouse gas emissions, land use, and freshwater use, so even a partial shift to plant-based eating has a positive impact.

No, it doesn't have to be. While some specialty vegan products can be pricey, the foundation of a plant-based diet—legumes, grains, vegetables, and fruits—is often more affordable than meat and dairy. Buying in bulk and focusing on seasonal produce can also help manage costs.
