Pulses & Legumes
This audit provides a comprehensive nutritional and environmental profile for the Pulse & Legume Power group. These eleven “protein engines” represent the primary structural foundations of a plant-based diet, distinguished by their exceptional delivery of Molybdenum, Folate, and Iron. From the complete amino acid profile of Soybeans to the unique neurological support of L-Dopa in Broad Beans and the cost-effective nutrient density of Red Kidney Beans, this group offers a dense matrix of slow-release carbohydrates and fermentable prebiotic fibres. Unlike animal proteins, these legumes provide significant antioxidant capacity—most notably in the anthocyanin-rich skins of Black Beans, Beluga Lentils, and Red Kidney Beans—while simultaneously acting as nitrogen-fixing agents that actively regenerate soil health during cultivation. 1 2 4
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 within a 16 storey building or a field/subterranean hybrid production system—to ensure every global citizen has local access to essential nutrition 1 2.
A high score indicates that the pulse can be grown in urban centres worldwide using aeroponics or hidden underground storeys, removing the “environmental debt” of global shipping and allowing for the rewilding of traditional agricultural land 1 10. Foods with lower Unity Scores are foods best suited to traditional production methods, that, while highly efficient at fixing nitrogen, currently rely on large-scale horizontal fields to reach full maturity and yield 1 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.
