Manganese, in which kidney beans are abundant, is one aspect of the antioxidant defense they provide. The crucial oxidative enzyme superoxide dismutase,responsible for disarming free radicals in mitochondria (the powerhouses of the cells), needs manganese. On top of that, the vitamin K in kidney beans has been shown to protect cells from oxidative stress, reducing chances of cancer.
The Vitamin K in kidney beans offers outstanding benefits for the brain and nervous system. The myelin sheath, or the outer wrapping around nerve, needs a fat called sphingolipids to form properly. Vitamin K is known to be essential for the synthesis of the sphingolipids, and therefore proper brain and nervous function. Kidney beans are also a good source of thiamin, which is critical for brain cell and cognitive function. This vitamin is needed for the creation of acetylcholine, a neurotransmitter used for memory and the lack of which is a significant factor in senility and Alzheimer’s disease.
The soluble fiber in kidney beans decreases the metabolism rate of the bean’scarbohydrates, which prevents blood sugar levels from rapidly spiking after ameal. The kidney bean’s high protein content also contribute to this effect.
Digestive Tract Health
The insoluble fiber in kidney beans helps to maintain bowel regularity by increasing stool bulk. The fermentation of dietary fiber in the large intestine also helps to maintain good bacteria in the digestive tract. Regular bowel movements are associated with a lower risk of colon cancer.
