Seeds & Essential Fats

This audit provides a comprehensive nutritional and environmental profile for the Seeds & Essential Fats group. These ten “superfoods” represent the primary vegan vehicles for fat-soluble nutrient delivery, specifically targeting Alpha-Linolenic Acid (ALA), Vitamin E, and diverse phytosterols. From the Selenium density of Brazil nuts to the complete amino acid profile of Sacha Inchi, these seeds and nuts provide the structural fats and mineral co-factors necessary for endocrine health and systemic anti-inflammatory responses. Unlike refined oils, these whole-food sources provide intact fibre and significant protein, making them the most nutrient-dense lipid sources in a plant-based diet.

Nutrition & Ethics

The Unity Score given below measures how effectively a food can be produced using open-source, decentralised technology—such as 8-storey vertical farms, bio-reactors, or controlled hybrid production system—to ensure every global citizen has local access to essential nutrition ^{1 15}.

A high score indicates that the food can be grown in urban centres worldwide, removing the “environmental debt” of global shipping and preventing wealthy nations from monopolising the land of developing regions ^{7 16}. Foods with lower Unity Scores are typically foods best suited to traditional production methods, that rely on specific, unique wild ecosystems; while these are vital for rewilding, they are less suitable for decentralised urban production ^{10 12}.

Google AI internal knowledge.
Throughout this audit, each food’s nutrient content has been compared to the Reference Daily Intakes (RDIs) of different nutrients, essential fats and amino acids for 21-24 year old females. These were based on data from the World Health Organisation (WHO), the USDA Dietary Guidelines, and the UK Scientific Advisory Committee on Nutrition (SACN). For full details, visit: https://naturalhuman.co.uk/reference-intakes/. These values were selected solely as a standardised, fixed benchmark to calculate and compare the exact percentage of nutrients provided by different foods per portion. Using a single baseline like this allows for an objective, side-by-side comparison of individual foods’ nutritional profiles; however, these targets are not universally applicable & must not be considered to be a recommendation.
