Blood cockles have a round, egg-shaped appearance with a thick outer shell. Inside, this shell is divided into two halves by a central ridge, creating a flat diamond shape.

Inside the shell, blood cockle meat is porcelain white and stands out with its high nutritional value.

Benefits of Blood Cockles:

• Cardiovascular Health: Blood cockles contain omega-3 fatty acids, which are good for the heart. While the omega-3 content is not as high as in other fish like salmon, it still supports heart function. Vitamin B12 in blood cockles is also beneficial for cardiovascular health.

• Brain Function: Nutrients in blood cockles, including omega-3 and vitamin B12, support brain health. Studies have shown that a lack of omega-3 and vitamin B12 can lead to brain development issues in children and affect brain function in adults. Blood cockles provide these nutrients and may help prevent brain aging.

• Immune System Boost: Blood cockles are rich in zinc, an essential mineral that strengthens the immune system. Zinc also acts as an antioxidant, helping to prevent inflammation and the risk of cancer.

Nutritional Composition of Blood Cockles:

• Blood cockles have high nutritional value, containing plenty of valuable nutrients with rich protein and low fat content. Additionally, they provide essential minerals that support overall health and development.
