Loach fish, often referred to as 'underwater ginseng', is a nutrient-rich food with numerous health benefits. It is high in essential amino acids, antioxidants, protein, calcium, phosphorus, and low in fat, making it ideal for malnourished individuals and those recovering from illness. It is also beneficial for liver and kidney diseases, blood circulation, and vitality-depleting diseases. The fish is believed to lower blood sugar, prevent diabetes, osteoporosis, and promote kidney metabolism. It is particularly beneficial for men due to its high lysine content, essential for sperm formation. The fish's high calcium and trace elements content is good for bone health, preventing rickets in children and osteoporosis in the elderly. Its skin mucus has anti-inflammatory and antibacterial effects, and the niacin content can help prevent cardiovascular disease.
