The formation of cells of the immune, bone and cardiovascular systems occurs with the participation of vitamin B9. It plays a major role in the functioning of the male reproductive system, supporting spermatogenesis, and in the early stages of gestation in women. In order to increase the intake of the substance from food, you need to know which foods contain folic acid.
Folic acid in foods.
The role of vitamin in the human body
Folic acid (folate, pteroylglutamic acid) is a water-soluble B vitamin that is not produced in human tissues. The main synthesis in the body occurs due to the microflora of the gastrointestinal tract, the remaining part of the substance comes from the outside (from food, synthetic forms of the vitamin in preparations).
Functions of folic acid.
Folates perform the following biological functions:
- regulate the production and development of new cells, which is important in early childhood and childhood (due to intensive growth, an increased amount of nutrients is required);
- participate in the synthesis of DNA molecules (disruption of this process threatens the appearance of cancerous tumors);
- support the formation of bone tissue cells, which is why they are prescribed for osteoporosis, restless legs syndrome and other musculoskeletal disorders;
- promote hematopoiesis, influence the synthesis of erythrocyte precursor cells (red blood cells);
- stimulate the immune system, provoking the formation of new cells in it, which increases the body’s resistance and protective functions;
- participate in the production of organic compounds (choline, nucleic acids, purine), individual amino acids (serine, glycine, histidine, methionine);
- improve the activity of the cardiovascular system, reducing the concentration of homocysteine in the body (blood pressure, cholesterol levels, and blood clotting are stabilized);
- regulate the functions of the central nervous system (reduce the risk of developing Alzheimer's disease, prevent the development of depression and nervous exhaustion);
- have a healing effect on infectious lesions of the oral mucosa;
- stimulate the production of viable sperm.
The effect of vitamin B9 is enhanced in the presence of ascorbic acid, tocopherol, and B vitamins.
For pregnant
When planning or carrying a pregnancy, folic acid is prescribed to prevent the following pathologies :
- early termination of pregnancy;
- intrauterine disorders in fetal development;
- anemia;
- placental insufficiency;
- premature birth.
The positive effect of the substance on the reproductive functions of the female body has been established.
Folic acid for pregnant women.
Planning pregnancy against the background of thrombophilia requires complex treatment with vitamin B9 to correct the level of homocysteine, which increases thrombosis.
Pregnancy in this case is associated with the risk of eclampsia and decreased placental function, and therefore also requires the administration of folic acid.
With the participation of the substance, the risk of pathologies of the fetal neural tube, brain development disorders (anencephaly, microcephaly), and congenital spinal canal bifida is reduced.
Folic acid stimulates the full formation of organs and systems of the unborn child, ensures the replication of cells of the nervous, hematopoietic, skeletal and visual systems.
Eggs
Including eggs in your diet is a great way to increase your intake of some essential nutrients, including folate.
Just one large egg contains 23.5 mcg of folate, or about 6% of the RDI ().
Including even a few servings of eggs each week is an easy way to increase your folate intake and help meet your needs.
Eggs also contain protein, selenium, riboflavin and vitamin B12 ().
They also contain high amounts of lutein and zeaxanthin, two antioxidants that may help reduce the risk of vision disorders such as macular degeneration (,).
Summary:
Eggs are a good source of folate, with about 6% of the RDI coming from just one large egg.
Daily requirement
The daily dose of folic acid required for the body , depending on age and hormonal levels:
- from birth to 1 year - 0.05 mg;
- 1-3 years - 0.07 mg;
- 4-6 years - 0.1 mg;
- 6-10 years - 0.15 mg;
- adults and adolescents over 11 years of age - 0.2 mg;
- pregnant women - 0.4 mg;
- during breastfeeding - 0.3 mg.
It is recommended to increase the dosage by 0.05 mg per day if:
- puberty;
- prolonged exposure to ultraviolet radiation;
- heavy sports loads and physical work;
- nervous tension or depression.
The synthetic (medicinal) form of folic acid is absorbed better than vitamin B9 obtained from food. The maximum permissible daily intake of the substance is 1 mg.
Daily requirement table.
Asparagus
Asparagus contains concentrated amounts of many vitamins and minerals, including folate.
In fact, a 90-gram serving of cooked asparagus contains about 134 mcg of folate, or 34% of the RDI ().
Asparagus is also rich in antioxidants and has anti-inflammatory and antibacterial properties ().
What's more, it's an excellent source of heart-healthy fiber, providing approximately 7% of the RDA for fiber in just one serving ().

Features of assimilation
Folacin is better absorbed by the body with the simultaneous presence of other vitamins in food: E, B12 and B6. In this sense, nuts are an ideal balanced option, especially since they can be eaten raw.
At the same time, salads made from green vegetables should be seasoned with corn or sunflower oil; they contain a lot of tocopherols. It is beneficial to add cottage cheese and hard cheese to these dishes. These dairy products are a source of three B vitamins at once.
What you cannot combine beneficial compounds with is alcohol and nicotine . Also, do not consume foods or medications containing folate and zinc at the same time. These substances interfere with the absorption of each other.
If there are problems with the intestines, then folacin will not be formed in the body, and if it comes with food, it will be poorly absorbed. Therefore, it is necessary to regulate the microflora of this organ by regularly consuming fermented milk drinks, fiber, fruits and vegetables.
Anti-seizure medications, hormones and contraceptives significantly affect the intestines, so taking them makes folate less absorbed. Stress and chronic diseases also interfere with their absorption.
Papaya
