Unlike soybeans, haricots contain only small amounts of isoflavones antioxidants. Total value of isoflavones is 0.27 mg per 100 grams of beans; daidzein and genistein at levels 0.01 mg and 0.20 mg respectively. Isoflavones have been found to reduce post-menopausal cancers and osteoporosis.
Haricots carry relatively less amounts of dietary fiber among the white beans. Nonetheless, they carry higher fiber than lentils and some green beans. Dietary fiber works as a bulk laxative that helps to protect the colon mucosa by decreasing its exposure time to toxic substances as well as by binding to cancer-causing chemicals in the colon.

Dry navy beans hold 364 μg of folates (94% of DV). Folate, along with vitamin B-12, is one of the essential co-factor for DNA synthesis and cell division. Adequate folate in the diet around conception and during the pregnancy may help prevent neural-tube defects in the babies.

100 g of beans hold 1185 mg or 25% potassium. It is essential electrolyte of cell and body fluids which helps to counter pressing effects of sodium on heart and blood pressure.
