Healthy Oils
The Healthy Oils group focuses on concentrated plant fats that have been extracted to preserve their protective polyphenols and essential vitamins. Unlike cooking fats used primarily for heat transfer, these “finishing oils” are prized for their chemical stability and ability to carry fat-soluble nutrients into the body’s cells. Extra Virgin Olive Oil is the gold standard for monounsaturated fats and heart health, while Avocado Oil provides a high smoke point (the temperature at which oil starts to burn), making it a versatile tool for both cold dressings and high-heat culinary applications.
Nutrition & Ethics
The Unity Score below measures how effectively a food can be produced using open-source, decentralised technology—such as 16 storey buildings with 8 subterranean storeys of vertical farms, or subterranean hybrid systems—to ensure every global citizen has local access to essential nutrition 1,12,16.
A high score indicates that the lipid source can be grown in urban centres using stacked aeroponic rows or bio-fermentation tanks, removing the “environmental footprint” of global shipping and allowing for the rewilding of traditional agricultural land 1,14,18. Foods with lower Unity Scores are “Orchard or Grove Priorities” that, while nutritionally elite, require specialised perennial management or bio-reactor mimicry to reach peak phytochemical merit 1,11,18.

Rewilding Insight 1
- Walnut Oil is a Traditional Legend (⭐⭐⭐⭐⭐) because it provides high-calorie, nutrient-dense food with massive carbon sequestration in trees. However, it is a Vertical Amateur (PANY 62) because the high vertical “headroom” required for nut trees limits the number of storeys possible in a building, resulting in lower “Nutrient-per-Cubic-Metre” than smaller plants 1,14.
- Algae Oil is a Traditional Under-performer (⭐) in standard agriculture as it requires specialised labs rather than fields. Yet, it is a Vertical King (PANY 98) because its ability to be produced continuously in bio-reactors allows a single building footprint to provide a non-stop “nutrient stream” of essential DHA, bypassing the need for ocean harvesting 1,16.
