That is IRON.
Iron becomes red when combined to oxygen. Our body contains 3 to 5 g of iron. Hemoglobin containing iron carries oxygen to the whole body. Previously, the most important role of iron was considered as carrying oxygen to the whole body. However, it has turned out that iron is playing an important role for the heart. Our muscle doesn’t move without iron. The heart is a mass of muscles so it doesn’t move well if iron is insufficient. There is a possibility that the increase of heart failure is related to lack of iron.
What do you need to eat to take iron efficiently?
Iron is contained a lot in liver, red meat and animal heart.
Decrease of eating meat with age is considered as a cause of insufficient iron.
