Chicken liver is a good source of folate, containing 254 mcg per serving
Folate, also known as vitamin B9, is a group of naturally occurring B-vitamins. In animals, the liver is the storage organ for folate. Chicken liver is also a good source of vitamin C, providing 47% of the RDA of vitamin C per 100 grams. This is in addition to its high protein content, with a protein density of approximately 25%.
Chicken liver is also a good source of other vitamins and minerals, including vitamin A, vitamin B12, selenium, and iron. It is relatively cheap and can be tasty when prepared well. However, it is important to note that chicken liver also contains a significant amount of copper, and pregnant women are advised to avoid consuming liver during pregnancy.
The cooking method can also affect the folate content of chicken liver. Studies have shown that cooking methods using hot, dry heat can cause significant folate losses. For example, applying 100% dry air at 180°C for 30 minutes can result in a folate reduction of more than 40%. On the other hand, steaming or sous-vide cooking at lower temperatures can help retain most of the folate content.

Cooking methods affect folate content, with steaming and sous-vide retaining the most
Chicken liver is one of the most nutrient-dense foods, being rich in high-quality protein and low in calories. It is a fantastic source of folate, a type of vitamin B. In animals, the liver is the storage organ for folate.
The folate content in chicken liver varies depending on the cooking method used. A study on the effect of different cooking methods on folate content in chicken liver found that steaming and sous-vide retained the most folate. After steaming (100°C/30 mins) or sous-vide (60°C/75 mins), the folate content in the liver did not differ significantly from that of raw liver (781 µg/100 g). Even liver cooked in a combi oven or grilled, which resulted in significant folate losses, showed much higher folate content (455-631 µg/100 g and 612-715 µg/100 g, respectively) than the most folate-abundant plant foods.
The stability of individual folate vitamers in chicken liver samples was also analysed in the study, and it was found that H4PteGlu was the least stable under different processing conditions. The lowest reduction of this folate form (not exceeding 60%) was observed in sous-vide (75°C/45 mins), steaming, and combi cooking with hot air (180°C) and relative humidity of 30% for 20 mins. In other cooking methods, losses ranged from 80% to 99%.
Cooking methods can significantly impact the nutrient content of food. In general, shorter cooking times, lower temperatures, and minimal water produce the best results for retaining nutrients. For example, microwaving is a good method for retaining nutrients due to its short cooking times. Boiling, on the other hand, can result in significant nutrient loss, with up to 40% of B vitamins and minerals lost during the process. Grilling and broiling can also result in nutrient loss as the juices drip from the meat.

Chicken liver is nutrient-dense, offering vitamins, minerals, and protein
Chicken liver is a nutrient-dense food, offering a wide range of vitamins, minerals, and protein. It is an excellent source of vitamin B12, vitamin A, selenium, and iron. Chicken liver is also a rare source of vitamin C within meat, containing 47% of the recommended daily amount per 100 grams.
Chicken liver is especially rich in folate, a natural form of vitamin B9, with one chicken liver providing 254 mcg of folate, which is about 64% of the daily recommended amount. The liver, in general, is the storage organ for folate in animals. The folate content in chicken liver can be preserved through certain cooking methods, such as sous-vide, steaming, and grilling, which result in minimal to moderate folate loss.
In comparison, an orange, a citrus fruit, is also a good source of folate, containing between 40 and 50 mcg, which is about 10% of the daily recommended value. Oranges are "orange foods" on the RMR Banting diet, meaning they are permitted in moderate amounts, while foods with higher folate content, like chicken liver, would be classified as "green foods", which can be eaten freely.
Chicken liver is also a significant source of protein, with a protein density of approximately 25%. This makes it comparable to chicken breast, which has a protein density of around 30%. However, when considering the additional nutritional benefits of chicken liver, it becomes a more attractive option for those seeking a high-protein diet.
While chicken liver is highly nutritious, it should be consumed in moderation as part of a balanced diet. It is also important to note that chicken liver has a distinct flavour that may be an acquired taste for some individuals. Overall, chicken liver is a nutrient-dense food, offering a wide range of vitamins, minerals, and protein, making it a valuable addition to a well-rounded diet.

Chicken liver is a nutrient-dense food, rich in high-quality protein and vitamins. It is a good source of vitamin C, vitamin B12, selenium, and folate. The liver, in general, is the storage organ for folate in animals. One chicken liver provides 254 mcg of folate, which is about 64% of the daily amount. However, the cooking method can affect the folate content in chicken liver. For example, grilling chicken liver results in a significant loss of folate, while steaming and sous-vide cooking methods preserve the nutrient better.
Oranges are also a good source of folate, with one orange providing about 10% of the daily value. Citrus fruits, in general, are known to be rich in folate. A glass of orange juice, especially if fortified with folic acid, can provide even more folate than the fruit itself.
While chicken liver provides a higher amount of folate per serving, oranges are also a folate-rich food. The recommended daily intake of folic acid is 400 micrograms, and including a variety of folate-rich foods in the diet can help meet this requirement.
In addition to oranges and chicken liver, other good sources of folate include leafy green vegetables, enriched grains, legumes, and other citrus fruits like avocados and pomegranates. A well-rounded diet that includes a variety of these foods can ensure adequate folate intake.
Folate, also known as vitamin B9, is important for overall health, especially for pregnant women. Adequate folate intake before and during early pregnancy can help prevent major birth defects of the brain and spine.

Folate is also known as folic acid, a B vitamin crucial for pregnant women
Chicken liver is a nutrient-dense food that is rich in high-quality protein and vitamins, including folate. Folate, also known as folic acid, is a B vitamin that is crucial for pregnant women. It helps the body make new cells, including blood cells, brain cells, skin, hair, and nails. Every new cell in the body needs folate, and it is especially important during early pregnancy for the development of the neural tube, which becomes the brain and spine.
Folic acid is the only form of folate that has been shown to help prevent serious birth defects called neural tube defects (NTDs). NTDs are major birth defects that occur in the first few weeks of pregnancy and can affect the baby's brain and spine. Taking folic acid supplements before and during pregnancy can help reduce the risk of these defects. For this reason, it is recommended that all women capable of becoming pregnant get enough folic acid in their diet or through supplements.
The recommended daily intake of folic acid for pregnant women is 400 to 600 micrograms. It is important to start taking folic acid at least one month before conception and to continue taking it during the first few months of pregnancy. If a woman has previously had a pregnancy affected by an NTD, the recommended daily intake of folic acid increases to 4,000 micrograms, and she should start taking it three months before becoming pregnant again.
Chicken liver is a good source of folate, but it is important to note that cooking methods can affect the folate content. Studies have shown that cooking with hot, dry heat can cause significant folate loss in chicken liver. However, cooking methods such as sous-vide, steaming, and combi cooking with hot air and relative humidity can help retain more folate content.
While chicken liver is a nutritious food, doctors generally recommend that pregnant women avoid eating livers during pregnancy due to the high amount of copper they contain. It is important for pregnant women to ensure they are getting enough folic acid through other dietary sources or supplements, as folate deficiency during pregnancy can have serious health consequences for the developing fetus.
