Finally, it is always better to vary our diet to get a wide range of nutrients rather than relying on a single type of food to provide our vitamin B9 intake.
III- The roles of vitamin B9 in the body:
A. Contributes to cell growth and division:
Vitamin B9, also called folic acid, plays a key role in cell growth and division. It helps in the production of new cells, which is crucial for the growth and development of the body, especially during periods of rapid growth such as pregnancy and early childhood. Vitamin B9 is also involved in the formation of DNA and RNA, the molecules that carry genetic information into our cells.
Additionally, vitamin B9 is essential for the formation of red blood cells, which carry oxygen in the blood, as well as for the production of neurotransmitters, the molecules that allow nerves to communicate with each other. Vitamin B9 can also help prevent chromosomal abnormalities, which is important for the long-term health of our body.
It is important to note that in order for vitamin B9 to play its role effectively in cell growth and division, it is necessary to have an adequate intake of vitamin B12 and iron, which work in tandem with vitamin B9. If we don’t get enough of these nutrients, our bodies may not be able to take full advantage of vitamin B9, which can affect our long-term health. It is therefore important to consult a health professional on how to maintain an adequate intake of vitamin B9, B12 and iron in our diet.
B. Participates in amino acid metabolism:
Vitamin B9, also called folic acid, is involved in the metabolism of amino acids, which are the building blocks of proteins. Amino acid metabolism allows our body to break down proteins into amino acids for use as an energy source or for the production of new proteins. Vitamin B9 is necessary for the formation of new proteins, especially for the formation of hemoglobin, which carries oxygen in the blood.
Additionally, vitamin B9 helps prevent protein deficiency by encouraging the production of new proteins. This can be especially important for people who are growing, athletes, the elderly, or people with chronic conditions that can cause protein loss.
It is important to note that for the metabolism of amino acids to function properly, it is necessary to have an adequate supply of vitamin B9 as well as other nutrients, such as vitamins B6 and B12, which also play a role in amino acid metabolism. If we don’t get enough of these nutrients, our bodies may not be able to metabolize amino acids properly, which can affect our long-term health. It is therefore important to consult a health professional on how to maintain an adequate intake of vitamin B9 and other nutrients in our diet.
C. Helps in the formation of red blood cells:
Vitamin B9 is essential for the formation of red blood cells. Red blood cells are blood cells that carry oxygen throughout the body. Vitamin B9 helps in the production of red blood cells by contributing to the formation of hemoglobin, the protein that carries oxygen in the blood.
Adequate vitamin B9 intake is important for avoiding anemia, a condition where the body lacks healthy red blood cells. Anemia can lead to fatigue, reduced physical and cognitive performance, and other health problems. Vitamin B9 can also help prevent anemia in cases of blood loss, by helping to produce new red blood cells.
It’s important to note that vitamin B9 works in tandem with other nutrients, such as vitamin B12 and iron, to support red blood cell formation. Therefore, it is important to consume a balanced and varied diet that includes rich sources of vitamin B9, B12 and iron, to support red blood cell formation and overall health. Foods rich in vitamin B9 include leafy green vegetables, legumes, fruits and fortified cereals. It is also possible to take vitamin B9 supplements in the form of tablets or capsules, but it is always better to consult a health professional to find out if these are suitable for our personal situation.
D. Intervenes in the production of DNA:
Vitamin B9 plays an important role in the production of DNA, deoxyribonucleic acid which is the fundamental molecule of genetic inheritance. DNA is the molecule that stores and transmits genetic information from one cell to another and from generation to generation.
Vitamin B9 is needed for cell division, an important process that occurs during tissue growth and repair. It also helps prevent chromosomal abnormalities by ensuring an accurate copy of DNA during cell division.
Vitamin B9 deficiency can lead to DNA deficiency and chromosomal abnormalities. Chromosomal abnormalities can lead to health problems, such as trisomy 21 (Down’s syndrome) and other chromosomal abnormalities that can cause genetic diseases and developmental problems.
It is important to consume enough vitamin B9 to support healthy DNA production and normal cell division. Foods rich in vitamin B9 include leafy green vegetables, legumes, fruits and fortified cereals. It is also possible to take vitamin B9 supplements in the form of tablets or capsules, but it is always better to consult a health professional to find out if these are suitable for our personal situation.
