1. How to distinguish green heart black beans from regular black beans

Black beans are a nutritious bean with many health benefits. In particular, green-heart black beans are considered to be a type of black bean with more biological activity and nutritional value, so they are often more expensive. Therefore, it is very necessary to distinguish between these two types of beans.

1.1 Based on the color of the seed core: This is the simplest and most accurate way.

  • Regular black beans: Black shell, yellow, white or ivory inside.
  • Green-heart black beans: The shell is also black, but when split open, the seed core has a characteristic green color.

1.2 Based on particle size and shape

  • Green bean: Smaller, firmer, plumper, almost the size of green beans.
  • Regular black beans: Larger, slightly round, sometimes uneven in size.

1.3 Based on the taste after cooking

  • When cooked, green-heart black beans are more fragrant, fatty, and rich. The bean water is clear and has a light taste.
  • Black beans usually have a light smell, bland taste, and slightly cloudy water when cooked.

2. Health benefits of green beans

Black beans, also known as black beans, are a medicinal herb used in many Oriental medicine prescriptions. According to traditional medicine, black beans have a sweet and mild taste, are neutral in nature, and are classified into the spleen and kidney meridians. They have the effect of nourishing the liver and kidney, strengthening the spleen, nourishing blood, eliminating wind, activating blood circulation, and promoting urination.

This medicine is often used to treat kidney failure (back and knee pain, tinnitus, frequent urination), spleen failure (poor appetite, bloating, fatigue), edema, dizziness, premature gray hair, dry skin, acne, itching, and postpartum weakness.

Many modern studies have also proven the health benefits of black beans. Black beans contain a lot of protein, lipids, carbohydrates; provide minerals such as calcium, phosphorus, iron and some vitamins such as B vitamins, vitamin PP, vitamin C and carotene.

Black beans are rich in essential amino acids needed by the body. In terms of health benefits, black beans are noted to help maintain strong bones, help lower blood pressure, support weight loss, contribute to diabetes control, prevent some cardiovascular risk factors and are good for the digestive system.

Studies also show that the reason green-heart black beans have green hearts is because they contain chlorophyll, lutein, isoflavone, etc. Thanks to these active ingredients, this type of bean has stronger antioxidant properties, is good for the heart and eyesight, and is considered to have more medicinal value than regular black beans.
