Nuts, Butters & High-Density Minerals
The Nuts, Butters & High-Density Mineral group focuses on nutrient-dense kernels that act as “biological storage units” for essential fats and rare minerals. Unlike many vegetables, nuts provide concentrated levels of Vitamin E, an antioxidant that protects cell membranes from damage, and Selenium, a trace mineral critical for thyroid function and DNA production. These items are the “high-capacity batteries” of the plant world, offering deep mineralisation and healthy lipids that support brain and skin health.
Nutrition & Ethics
The Unity Score given below measures how effectively a food can be produced using open-source, decentralised technology—such as the integration of dwarf nut varieties into 8-storey green living walls or the use of subterranean bio-reactors—to ensure every global citizen has local access to essential nutrition 1 2.
A high score indicates that the nut can be grown on the “vertical skin” of urban buildings or produced via precision fermentation in hidden underground storeys, removing the “environmental footprint” of global shipping and allowing for the rewilding of traditional tropical and temperate landscapes 1 14. Foods with lower Unity Scores are those best suited to traditional outdoor production, which currently rely on massive, slow-maturing wild canopies or expansive horizontal orchards to reach full yield 1 15.

- 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.
