Addressing Nutritional Gaps in the 80/10/10 Diet
The 80/10/10 diet, popularized by Dr. Douglas Graham, is a low-fat, raw vegan eating plan built on a macronutrient ratio of 80% carbohydrates, 10% protein, and 10% fat. While this approach emphasizes consuming whole, unprocessed fruits and vegetables, its restrictive nature makes it prone to certain nutritional deficiencies. To ensure a complete diet, you must deliberately supplement and incorporate specific foods to cover these gaps.
Essential Vitamins and Minerals to Add
The most commonly lacking nutrients on a strict 80/10/10 plan include vitamins B12, D, and E, as well as minerals like iodine, zinc, and calcium. Since vitamin B12 is not available in plant-based whole foods, a reliable supplement is non-negotiable. Vitamin D, essential for bone health, is often deficient in vegan diets and requires either supplementation or adequate sunlight exposure. Iodine, crucial for thyroid function, is another nutrient to address, as the diet avoids iodized salt.
- Vitamin B12: A B12 supplement is the only reliable way for vegans to meet this requirement.
- Vitamin D: Fortified plant milks or orange juice can help, but a supplement is often necessary, especially for those with limited sun exposure.
- Iodine: Small amounts of dried seaweed like kelp or nori can be added to meals.
- Zinc: Foods like pumpkin seeds, hemp seeds, and lentils are good sources. Zinc supplements may also be beneficial.
- Calcium: Increase intake of calcium-rich greens such as kale, collard greens, and spinach. Fortified plant milk is another option.
Incorporating Essential Fatty Acids
The low-fat nature of the 80/10/10 diet can lead to a deficiency in omega-3 fatty acids, particularly EPA and DHA, which are vital for brain and heart health. While the diet allows for limited nuts and seeds, they primarily contain ALA, which has a poor conversion rate to EPA and DHA in the body.
To ensure adequate intake, consider these additions:
- Algae oil supplements: These are a direct source of preformed EPA and DHA and are the most efficient option for vegans.
- Ground flaxseed or chia seeds: While not as efficient, incorporating these daily can still contribute to your omega-3 intake.
- Walnuts: A handful of walnuts can provide some ALA omega-3s and add a crunchy texture to salads.
The Importance of Plant Matter Variety
While the 80/10/10 diet emphasizes fruits, adding a broader range of non-fruit plant foods is essential for a complete nutritional profile. Leafy greens are a primary source of many vitamins and minerals, but other vegetables and legumes offer unique benefits, including fiber and unique micronutrients.
For improved digestion and gut health, some advocates suggest lightly steaming vegetables. Adding a small portion of cooked lentils or beans can also provide a more significant protein boost without deviating too far from the dietary philosophy.
Comparison of Standard 80/10/10 vs. Complete 80/10/10
| Aspect | Standard 80/10/10 Diet | Complete 80/10/10 Approach |
|---|---|---|
| Micronutrients | Potentially deficient (B12, D, iodine, zinc, calcium) | Addresses deficiencies with targeted additions |
| Fatty Acids | Low in essential omega-3s (EPA/DHA) | Includes direct sources like algae oil for EPA/DHA |
| Protein | Relies on minimal fruit/green protein | Supplements with high-protein seeds or legumes |
| Food Variety | Predominantly fruits and tender greens | Expands to include diverse vegetables, legumes, and seeds |
| Sustainability | Difficult for long-term adherence due to restrictions | More sustainable with strategic, balanced additions |
A Path Toward a Complete Raw Diet
Achieving a complete nutritional profile on a raw vegan diet requires careful planning and a willingness to look beyond the strictest interpretation of the 80/10/10 rule. By incorporating specific supplements for crucial nutrients like B12, supplementing with reliable omega-3 sources, and expanding the range of plant matter beyond just fruits and leafy greens, you can transform this restrictive diet into a more sustainable and nutritionally sound eating plan. Always listen to your body and consult with a healthcare professional or registered dietitian when making significant dietary changes, especially regarding supplementation.
A Note on Supplements and Whole Foods: For those on a raw food diet, finding a reliable and bioavailable source of key nutrients is paramount. While some followers may argue against supplements, scientific evidence clearly indicates they are necessary to prevent serious deficiencies. Choosing whole food sources like seeds, algae, and seaweed whenever possible is a great way to augment nutrition naturally, but critical needs like B12 must be met via supplementation.

Conclusion
Making the 80/10/10 diet nutritionally complete involves proactive supplementation and diversifying your food choices. By adding key vitamins like B12 and D, essential omega-3s from algae oil, and a wider variety of plant-based whole foods, you can mitigate the risks of common deficiencies. This approach shifts the focus from a rigid ratio to a balanced, sustainable, and truly nourishing raw vegan lifestyle. The result is a diet that not only aligns with its core philosophy but also supports long-term health and well-being.
