Faba beans (Vicia faba L.) are suitable for tropical to temperate climates. They are more tolerant of acidic soils. The optimal pH level for growing fava beans is between neutral and alkaline (pH 6.5 to 8.0). Flowers are usually pollinated by insects such as honey bees, bumblebees, and solitary bees. Faba beans are one of the most important edible legumes. These beans are very nutritious due to their high content of proteins, minerals, vitamins, and numerous bioactive compounds such as polyphenols and carotenoids. It is a good source o lysine-rich protein and a good source of levodopa (1-3,4-dihydroxyphenylalanine), a dopamine precursor that has potential as a drug to treat Parkinson's disease. These beans are high in non-nutritive secondary metabolites and high in fiber, both of which are good for human health.
