Anemia is the consequence of an abnormal decrease in hemoglobin and red blood cells in the blood. The causes and types of anemia are multiple. Among these causes, certain vitamin deficiencies predispose to so-called macrocytic or megaloblastic anemia, different from iron deficiency anemia linked to iron deficiency. Indeed, vitamin B9 (folic acid) deficiency causes a dysfunction in the production of red blood cells. Therefore, to prevent this type of anemia it is essential to focus on foods rich in vitamin B9.

The place of vitamin B9 in anemia

Anemia corresponds to a hemoglobin level in the blood substandard. There is no single anemia, but several anemias. This guide supports nutritional deficiency vitamin B9, that is to say macrocytic anemia (normochromic and aregenerative).

Vitamin B9 is hematopoietic: it is essential for the production of red blood cells. Without it, the maturation of red blood cells is incomplete: we observe a delay and a defect in cell division. As a result, red blood cells are “larger” (macrocytic) and more fragile. Insufficient intake through food is the primary cause of vitamin B9 deficiency.

Vitamin B9 deficiency is rarely symptomatic. It is detected during a “ordinary” blood test. However, the repercussions of a vitamin B9 deficiency are serious, particularly for fetuses: in a pregnant woman, vitamin B9 deficiency leads to neural tube defects in the fetus. As for macrocytic anemia, it is expressed after a significant and long deficiency. It causes the typical symptoms of anemia: intense fatigue, paleness, shortness of breath, etc.

The role of diet

We are unable to synthesize vitamin B9. In addition, the stocks in the body are tiny. Food must cover vitamin needs daily.

A vitamin B9 deficiency is recurrent when the insufficient consumption of fruits and vegetables. Indeed, vitamin B9 is found mainly in foods of plant origin. In case of macrocytic anemia, it is essential to restore vitamin B9 stocks.

Foods rich in vitamin B9

Liver, the food richest in vitamin B9

The liver is a rather unusual red offal. Due to its storage role in the body, it offers a wide range of numerous micronutrients, including vitamin B9. On average, 100 g of liver provides 700 mcg of vitamin B9.

We recommend you :

  • 1 meal per week with liver: 50 g of liver meets the daily requirement of vitamin B9.
  • de promote minimally invasive cooking: steam, poach, etc.

Dried vegetables

Dried vegetables are rich in vitamin B9. Indeed, for 100 g of dried vegetables, we find on average 400 µg of vitamin B9.

We recommend you :

  • 2 meals based on dried vegetables per week. A portion of dried vegetable (60 g of dried vegetable, weighed raw) provides approximately 250 µg of vitamin B9, or 75% of the nutritional references for the population (RNP).

  • to vary the dried vegetables: red beans, white beans, flageolet beans, broad beans, chickpeas, split peas, coral lentils, green lentils, lupins, soybeans, etc.

  • be careful not to overcook dried vegetables, due to the sensitivity of vitamin B9 to heat.

Fresh fruits and vegetables

Vitamin B9, or folic acid, is omnipresent in fruits and vegetables. It is mainly present in leafy vegetables, from which it takes its scientific name: “folium” means leaf in Latin.

We recommend you :

  • minimum five fruits and vegetables per day, with a majority of leafy vegetables.

  • the vegetables richest in vitamin B9: spinach, cabbage, lettuce and asparagus. 100 g of raw spinach provides 200 µg of vitamin B9, or 60% of the RNP.

  • to favor raw vegetables or quick cooking methods: steam, wok, snacks, etc.

  • to favor seasonal fruits and vegetables, because they are richer in vitamin B9.

  • to favor local fruits and vegetables, to reduce transport times: a factor reducing the vitamin B9 content in plants.

A pollen cure

This product made from the stamens of the flower contains many micronutrients, including vitamin B9. Depending on the quantities consumed during a pollen cure (1 tablespoon per day), we find 200 µg of vitamin B9, or 60% of the daily needs.

We recommend you to introduce a cure of pollen, when it's necessary.

Nuts and seeds

Nuts and seeds contribute to vitamin B9 intake. However, given the quantities consumed, they alone do not completely meet the daily needs of vitamin B9.

We recommend you :

  • 15 g of seeds and nuts per day, which meets approximately 15% of the daily requirement for vitamin B9.

  • to favor unroasted and unsalted nuts.
