Anthocyanins are healthful flavonoid pigments that give foods like blueberries, blackcurrants, raspberries, red grapes - and black beans - their intense color and superior antioxidant properties. The overall anthocyanin content of black beans is estimated to be around 214 milligrams per 100 grams 1. The strong antioxidant properties of black turtle beans are largely attributable to their high concentration of anthocyanins such as delphinidin, petunidin, and malvidin. The black bean has more antioxidant activity than any other bean. Among the tested varieties, white beans had the lowest levels of flavonoids and yielded the weakest antioxidant activity. The researchers also found that the darker the seed coat of the bean, the higher the flavonoid content (in general). Black beans came out on top, having more antioxidant activity, gram for gram, than the other beans. Black Beans Top the List of Antioxidant-Rich BeansĪ study published in the Journal of Agricultural and Food Chemistry in 2003 investigated the antioxidant activity of 12 common varieties of dry beans.

Note: Like all common beans, raw black turtle beans contain toxic lectins and therefore you should always cook them properly before eating them. Anthocyanins are flavonoid pigments that give many black and blue fruits, berries and legumes their extraordinary health benefits. But the health benefits of black turtle beans go way beyond the call of duty as these little black gems offer extraordinary antioxidant benefits resulting from their high concentration of anthocyanins. Like all common beans, black beans are loaded with protein, fiber, molybdenum, zinc, and copper. Health Benefits of Eating Black Turtle Beansīlack turtle beans, commonly known as black beans, are a variety of the common bean (Phaseolus vulgaris).
