In addition to conventional antioxidant nutrients like vitamin C and beta-carotene, green beans contain important amounts of the antioxidant mineral manganese. But the area of phytonutrients is where green beans really shine through in their antioxidant value. Green beans contain a wide variety of carotenoids (including lutein, beta-carotene, violaxanthin, and neoxanthin) and flavonoids (including quercetin, kaemferol, catechins, epicatechins, and procyanidins) that have all been shown to have health-supportive antioxidant properties. In addition, the overall antioxidant capacity of green beans has been measured in several research studies, and in one study, green beans have been shown to have greater overall antioxidant capacity than similar foods in the pea and bean families, for example, snow peas or winged beans. Green beans may be a particularly helpful food for providing us with the mineral silicon. This mineral—while less well known that minerals like calcium and magnesium—is very important for bone health and for healthy formation of connective tissue. Green beans have recently been shown to stack up quite well against other commonly-eaten foods as a good source of absorbable silicon. Grown by Wolf in Montville.
