Organic beans are very rich in dietary fiber and folic acid (vitamin B9). They are a good source of copper, manganese, phosphorus, thiamine (vitamin B1), proteins, iron, and magnesium. They also contain vitamins C and E, calcium, carbohydrates, and trace elements.

Some types of beans, such as black beans, red beans, and pinto beans, are also very rich in molybdenum, with a cup possibly containing up to 285% of the Daily Intake. They are very low in fat.

Organic beans differ from conventionally grown beans due to their higher concentration of nutrients, particularly antioxidants, vitamins, and trace elements.
