Chirimenjako / Dried Young Sardines

Chirimenjako is rich in calcium, which helps maintain healthy bones and teeth. Because chirimenjako can be eaten with the bones, it is an efficient source of calcium, and is recommended for growing children and elderly people who need to prevent osteoporosis. Chirimenjako is also rich in vitamin D, which helps with calcium absorption.
Chirimenjako also contains a lot of DHA and EPA, which are omega-3 fatty acids that support the health of the heart and brain. These lower cholesterol levels in the blood and help prevent arteriosclerosis and heart disease. They also contain a lot of vitamin B12, which is involved in important parts of the body, such as the synthesis of nucleic acids necessary for protein and DNA and the growth of red blood cells.
However, as chirimenjako is boiled in salt water it is high in sodium, so it is best to be aware of the quantity you eat. It is a good option to use chirimenjako instead of salt and other salty seasoning on your dishes, such as sprinkling it on a salad and eating it with vegetables that are high in potassium, or even putting it on rice or bread.
