These are also referred to as Honey Beans.
They are a pleasant Tasty Nutritious Savoury Bean.
Oloyin beans (also known as Nigerian Honey Beans or Ewa Oloyin, a cultivar of Vigna unguiculata / cowpeas) have a distinct protein and nutritional architecture compared to Kidney Beans, Faba Beans, and Chickpeas.
Because Oloyin beans belong to the cowpea/black-eyed pea family rather than the Phaseolus (common bean) or Vicia family, their protein structure behaves differently in terms of digestibility and antinutrient profile.
Protein & Amino Acid Breakdown
| Nutrient / Metric | Oloyin (Honey) Beans | Kidney Beans | Faba Beans Dried Split Broadbeans | Chickpeas |
| Species | Vigna unguiculata | Phaseolus vulgaris | Vicia faba | Cicer arietinum |
| Crude Protein (Dry) | 22% – 25% | ~23% – 24% | 26% – 32% | ~19% – 21% |
| Lysine Level | Very High | High | Extremely High | High |
| Methionine & Cysteine | Low (Limiting) | Low (Limiting) | Lowest (Limiting) | Slightly Higher |
| Digestibility Rate | High (Easier on gut) | Moderate | Moderate (Skin retards it) |
Key Comparisons Across the Four Legumes
1. Faba Beans (The Heavyweight Protein Champion)
- Protein Density: Faba beans hold the highest raw protein concentration of the four (often hitting 30%+ in split varieties).
