  • Minerals: One serving of black beans provides an impressive amount of minerals like iron (essential to transport oxygen), phosphorus (required for bone health), magnesium (critical to hundreds of biochemical reactions), potassium( critical in maintaining normal heartbeat), copper( used by many enzymes in cellular metabolism)and zinc(essential for growth, immune system function and wound healing).
  • Phytonutrients: Black beans are a rich source of antioxidants like flavonoids and other phytochemicals that can help to prevent several chronic diseases and reduce inflammation.

How Cooking Affects the Nutritional Value:

The method of cooking black beans affects their nutritional content. Overcooking can destroy some of its nutrients. However, soaking the beans overnight before cooking increases its nutrient absorption rate. Boiling or pressure-cooking black beans is the best way to retain maximum nutrient value.

  • Incomplete digestion of raw beans can lead to trouble such as bloating, gas, and indigestion due to an increased load on the digestive system.

Health Risks Associated with Eating Raw Beans

  • Eating raw or undercooked black beans can cause food poisoning symptoms such as nausea and diarrhea caused by naturally occurring toxins in the bean cells called lectins.
