What does rich in iron and rich in protein mean?

There is some confusion between iron and proteins, more particularly about the properties of a food on the body. rich in iron or rich in protein. We can assume that the complication to differentiate between the trace element and the macronutrient comes from the cartoon. Popeye. In fact, the famous character only has to swallow a can of spinach to magically have big powerful muscles.

Since muscles are associated with protein, some have concluded that iron and protein are the same. Others say that Spinach they are rich in iron and protein.

Difference between iron and protein: the role of each for the body

The difference between the iron and protein can be seen in the role they play in the body.

Role of iron for the body

Iron is a trace element essential for the transport and storage of oxygen in the body. In fact, it represents one of the main components ofhemoglobin contained in red blood cells. They are those that transport the oxygen collected by the lungs to all the organs of the body.

Know that iron is also part of the composition of myoglobin, a metalloprotein found in the muscles of vertebrate organisms. Myoglobin is used to transport and store oxygen, but in the muscles. The body also needs iron to produce the enzymes necessary for essential metabolic reactions. For example, the synthesis of DNA or organic compounds like dopamine and norepinephrine.

Finally, this trace element allows the process of cellular division.

Usefulness of proteins for the body

In the body, proteins serve several important functions. The best known is undoubtedly the one that is filled at a structural level. This is the cbuild and renew muscle cells. Athletes consume it regularly to optimize their recovery after a training session.

Aside from the structural function provided by collagen and keratin, proteins serve other functions. Particularly at the level of oxygen transport in the body. Function provided by hemoglobin and myoglobin, which are transporter proteins.

We look at other proteins, such as:

Also, proteins are the only source of nitrogen for the human body.

The daily iron requirements are as follows:

What foods are rich in iron?

Among the foods rich in iron, we can find (per 100 g of product):

Recommended daily protein intake

In a healthy adult, the recommended daily dose of protein is 0.83 g / kg / day.
